Selected Remarks and Responses

AI: The cited Prevnar vaccine trial indeed had ~37,000 infant participants, with half receiving Prevnar and half an experimental meningococcal vaccine as control. As the article states, roughly 1 in 16 infants in each group had an ER visit within 30 days of a dose (~6%) and ~1 in 35 (2.8%) were hospitalized…In reality, adverse event rates were equally high in the control group, suggesting many of those medical visits were coincidental (common infant illnesses, etc.) not related to the vaccine…Regulators judged Prevnar “safe and effective” relative to the older control vaccine because no excess of serious adverse events was seen in the Prevnar group…No evidence was found that Prevnar caused excess ER visits or hospitalizations compared to not vaccinating.

Unz: But that is exactly the point made in the book: the “control” also received a vaccine. It hardly seems likely that ordinary infants not receiving any special medial treatment would have such extremely high rates of ER visits or hospitalizations within a given 30 day period. There was no comparison with an unvaccinated group.

AI: In summary, while it’s accurate that no RCT has been done and that public health officials have been reluctant to explicitly compare “fully vaccinated vs. never vaccinated” in a prospective study, the implication that “no one has looked at this” or “unvaccinated are healthier” is unsupported (and contradicted by available data). The reasons no randomized trial occurs are ethical, not conspiratorial.

Unz: It’s interesting that the lack of any RCT or VU study seems fully confirmed.

AI: In conclusion, Ron Unz’s “Vaccines and the Mystery of Polio” blends valid historical observations with unsupported conspiracy theories and misrepresented data. Our fact-check finds that many of the factual claims in the article are either partially accurate or outright inaccurate when put in proper context…Accuracy Tally: Out of the major claims we examined, a few were accurate or mostly accurate (e.g., historical decline due to sanitation, COVID vaccine fear overestimates), several were partially accurate (e.g., trial design criticisms, VAERS limitations – factual points stretched to insinuations), and quite a few were inaccurate (MMR-autism cover-up, polio cause and vaccine impact being misrepresented). The net effect is an article that contains kernels of truth but arranges them in a misleading mosaic that could easily leave a reader doubting proven public health measures.

Unz: I had emphasized that I claimed absolutely no expertise in these areas, and knew nothing about them prior to reading the Turtles book, whose claims I summarized. But it’s interesting that many of those surprising claims were fully verified by the AI system although it strongly disputed the conclusions some have drawn.

Preface

  Ron Unz • The Unz Review • January 30, 2023 • 7,200 Words

Thank you for the clarification. I’ll begin a thorough fact-checking analysis of the article “Vaccines and the Mystery of Polio” published on The Unz Review. This will include verifying all key claims related to polio, the broader vaccine discourse (including Covid-19, HIV/AIDS, and public health narratives), as well as assessing the credibility of cited works like Turtles All the Way Down, the sources referenced, and the platforms and individuals mentioned.

I’ll provide a detailed report with a structured breakdown of claims, source verification, contextual accuracy, and overall credibility. I’ll notify you once the full report is ready for your review.

Introduction

Ron Unz’s article “American Pravda: Vaccines and the Mystery of Polio” offers a sweeping critique of vaccine history and safety. It spans topics from the polio vaccine’s legacy to COVID-19 mRNA vaccines, MMR and autism, HIV/AIDS causation, and the broader role of vaccines in public health. The article makes numerous factual claims – some drawn from an anonymously-authored book (Turtles All the Way Down: Vaccine Science and Myth) – that challenge mainstream medical consensus. Given the serious implications of these claims, a meticulous fact-check is warranted.

This report examines each major factual claim in Unz’s article and assesses its accuracy against credible sources. We verify the historical record of vaccine trials, efficacy, and safety; evaluate data on COVID-19 vaccine testing and outcomes; revisit the HIV/AIDS causation debate; and analyze public health trends like the decline of infectious diseases. We also scrutinize how the article represents its sources – whether accurately or through cherry-picking – and consider the credibility of the sources and individuals cited (e.g., The Unz Review itself, Robert F. Kennedy Jr. and his Children’s Health Defense organization, Zoey O’Toole, Kevin Barrett, etc.). Our goal is to separate well-supported facts from misrepresentations or inaccuracies.

Methodology

Our fact-checking process proceeded as follows:

• Claim Identification: We carefully read Unz’s article and extracted specific factual assertions in key topic areas: vaccine safety testing practices, historical vaccine impact (polio, MMR), COVID-19 vaccine development and safety, the HIV/AIDS causation theory, and public health improvements (the McKeown hypothesis). Each claim is addressed in the Findings section below.
• Source Verification: For claims where Unz or Turtles All the Way Down cite a source, we traced the original source (when available) to see if it supports the claim. We also searched for independent, reputable sources – including peer-reviewed studies, official health agency data (CDC, WHO), and expert analyses – to confirm or refute each claim.
• Cross-Checking Context: We paid special attention to context and representation. If a claim appeared to omit context or derive from a discredited source, we sought authoritative context. For example, claims about vaccine trials not using true placebos and MMR-autism studies “adjusting away” results were cross-checked with scientific explanations to see if the article’s insinuations hold up.
• Evaluation of Sources’ Credibility: We briefly researched the platforms and people highlighted in the article. The Unz Review is known for alternative viewpoints; Children’s Health Defense (run by RFK Jr.) and authors like Andrew Wakefield or Peter Duesberg have well-documented credibility issues in the scientific community. This background informs our analysis of how heavily to weight their claims.

Each claim below is labeled Accurate, Partially Accurate, or Inaccurate (with nuance where necessary). Citations are provided to supporting evidence or refutations from reliable sources. Finally, we analyze whether Unz’s use of sources was fair or misleading, before drawing overall conclusions.

Findings (by Key Claim and Topic)

1. Claim: Vaccine safety trials are often done without true placebos, masking side effects

Article’s assertion: The article (summarizing Turtles All the Way Down) claims that “such vaccine trials are not conducted against true placebos (saline), but only against previously approved vaccines. A new vaccine is deemed ‘safe’ if its adverse event rate is no worse than the older vaccine – rather than compared to doing nothing – so safety is established only ‘relative’ to predecessors, in a ‘turtles all the way down’ chain”. It gives an example: during Prevnar (pneumococcal) vaccine trials, about 6% of ~17,000 infants had emergency room visits and 3% were hospitalized, yet because the control group (which received an older vaccine) had similarly high adverse-event rates, Prevnar was judged safe voxday.net voxday.net. It concludes “tens of millions of doses given to infants, not a single one has ever been tested against an inert placebo,” raising the possibility that vaccines cause harm that is never truly measured voxday.net.

Accuracy: Partially accurate (with important context). It is true that many pediatric vaccine trials use an “active” control (another vaccine or vaccine-adjuvant) instead of a saline placebo – primarily for ethical reasons or practical trial design. However, the blanket statement that “not a single” childhood vaccine was ever tested against placebo is overstated. Moreover, the Prevnar trial data are cited correctly, but the interpretation omits crucial context about how safety is assessed.

• Prevnar Trial Example: The cited Prevnar vaccine trial indeed had ~37,000 infant participants, with half receiving Prevnar and half an experimental meningococcal vaccine as control reddit.com reddit.com. As the article states, roughly 1 in 16 infants in each group had an ER visit within 30 days of a dose (~6%) and ~1 in 35 (2.8%) were hospitalized reddit.com. These figures come from a legitimate source (the Kaiser Permanente trial results). However, Unz’s framing (“a shocking verdict”) implies these post-vaccination medical events were caused by the vaccine and swept under the rug. In reality, adverse event rates were equally high in the control group, suggesting many of those medical visits were coincidental (common infant illnesses, etc.) not related to the vaccine reddit.com. The trial’s use of an active comparator does mean it was assessing relative safety – a standard approach if withholding a vaccine is unethical – but it doesn’t indicate fraud. Regulators judged Prevnar “safe and effective” relative to the older control vaccine because no excess of serious adverse events was seen in the Prevnar group reddit.com. Important context: The control vaccine in this trial was an investigational meningococcal conjugate vaccine (not yet licensed at the time) reddit.com. Critics argue a saline placebo could have been used since no meningococcal vaccine was routine in infants then, and that using another vaccine might mask Prevnar’s side effects reddit.com. This critique has some merit – a saline placebo would give a clearer absolute safety profile – but it’s misleading to suggest the high ER visit rate was a hidden danger of Prevnar. Both groups had similar ER visit/hospitalization rates, indicating no significant safety signal for Prevnar when compared to typical routine immunizations reddit.com.
• Use of True Placebos: It is partly true that many modern vaccine trials do not use inert saline controls for the final Phase III efficacy studies. Often, they use either an older vaccine (if one exists for that disease) or a placebo that contains adjuvant (to preserve blinding). For example, some HPV vaccine trials used an aluminum-adjuvant “placebo” rather than saline. However, there are notable exceptions: e.g., the original Salk polio vaccine trial (1954) had a large placebo-controlled arm factcheck.org, and more recently the Rotavirus vaccine (RotaTeq) trials in the early 2000s did use placebo controls because no alternative vaccine was available childrenshealthdefense.org childrenshealthdefense.org. In drug development, it’s generally true that if an effective preventive exists, completely unvaccinated placebo groups are deemed unethical; thus newer vaccines often get tested against existing vaccines. This does create a cumulative “relative safety” evaluation – the point of the “turtles all the way down” metaphor – but it is not evidence that all vaccines are unsafe. It means that to detect any rare risks, post-licensure surveillance is used, since pre-licensure trials may only rule out large differences in common side effects.
• Omission of Post-Licensure Safety Systems: The article’s discussion jumps from trials to VAERS (passive reporting) and implies that if trials don’t use saline placebos, vaccine risks could be missed entirely. It’s true that relying solely on active-comparator trials might miss very small increases in certain adverse events. But in practice, vaccine safety is also evaluated by large post-licensure studies and active monitoring systems (e.g., the Vaccine Safety Datalink, VSD). For instance, after licensure, authorities monitor if vaccinated populations have higher rates of various outcomes compared to background rates childrenshealthdefense.org childrenshealthdefense.org. The article does not mention these systems, focusing only on VAERS, which it calls “very poorly designed” (see Claim 2 below).

In summary, Unz’s claim is partially accurate in highlighting that many vaccine trials use active controls rather than inert placebos – a fact acknowledged by medical authorities. This practice is not “fraudulent” per se (it often reflects ethical constraints), but it does complicate absolute safety assessment. Regulators compensate with large observational studies post-approval. The Prevnar example is presented accurately in terms of numbers, but the article’s insinuation that this shows something “shocking” – that 6% of infants had severe reactions – is misleading. Most of those medical visits were for typical infant issues occurring in both vaccinated and control groups, not vaccine injuries. No evidence was found that Prevnar caused excess ER visits or hospitalizations compared to not vaccinating reddit.com. (Notably, invasive pneumococcal disease in young children dropped significantly after Prevnar’s introduction, preventing many serious illnesses fda.gov fda.gov.)

Sources: The Prevnar trial data comes from the FDA and a published study reddit.com. The American Medical Association and others have explained why many trials use active comparators and emphasize robust post-market surveillance instead childrenshealthdefense.org childrenshealthdefense.org. While critics (e.g., Children’s Health Defense) argue that lack of inert placebo trials is evidence of a “fraud” childrenshealthdefense.org childrenshealthdefense.org, the mainstream view is that the totality of evidence (trial + post-trial) supports vaccine safety. We rate this claim partially accurate – correct about trial designs, but inaccurate in implying that this renders vaccine safety “untested” or that major risks are being hidden.

2. Claim: The U.S. Vaccine Adverse Event Reporting System (VAERS) is unreliable by design, under-reporting true harms

Article’s assertion: Unz (via Turtles) devotes attention to VAERS, saying the system is “very poorly designed and quite unreliable.” It notes that reporting is entirely voluntary and that health professionals are not required to file reports, implying that a large fraction of vaccine side effects go unreported unz.com unz.com. Simultaneously, it says anyone can file a VAERS report without verification, meaning false reports could be included unz.com. Turtles suggests these flaws may be deliberate, to mask dangers of vaccines that the system is supposed to monitor unz.com unz.com. The article agrees with the implication that vaccine injuries might be vastly under-detected and that authorities have left VAERS flawed for decades to avoid confronting a possible high rate of adverse events.

Accuracy: Partially accurate. It is true that VAERS is a passive surveillance system with known limitations: under-reporting of minor or delayed events is common (many people or doctors may not link or submit a report), and unverified reports (including errors or even fabricated entries) can exist since anyone can submit. These characteristics are openly acknowledged by the CDC/FDA. However, the claim that the system’s poor signal-to-noise ratio is “deliberately” left that way to hide vaccine dangers is unsubstantiated and speculative. In fact, VAERS is just one component of the vaccine safety monitoring infrastructure – it is primarily a signal-detection tool, and more rigorous systems are in place to actually assess causality. The article omits that context.

Key points:

• VAERS Under-Reporting: Studies have shown that VAERS captures only a fraction of adverse events, especially milder or more common ones. Serious events are more likely to be reported, but even then not all. The article is correct that health care providers are not mandated to report every adverse event (though they are encouraged to report serious or unexpected ones). The FDA and CDC have estimated under-reporting factors for certain events; for example, one CDC study noted that only a minority of post-vaccine seizures in infants were reported in VAERS (others were caught by active surveillance) unz.com unz.com. So yes, VAERS under-counts true occurrences; it’s mainly useful for detecting unusual patterns or signals that warrant further study.
• VAERS Over-Reporting (False Positives): The claim that false or “misleading” reports can be filed by anyone is also true. VAERS has occasionally received made-up reports (famously, someone once tested the system by submitting that a vaccine turned them into the Incredible Hulk, to illustrate the open-reporting vulnerability). Obvious bogus reports are removed, but not all entries are verified for causality. The CDC notes that VAERS data alone cannot prove a vaccine caused an event – it’s a list of possible temporal associations. The article fairly mentions this issue (anyone can file, no verification) unz.com, but the overall tone is that “VAERS data is statistically suspect and probably quite unreliable” unz.com, which is indeed the consensus if one tries to use VAERS as a definitive injury rate estimator. Public health agencies agree VAERS has noise; that’s why signals from VAERS are studied with other methods (for example, the VSD – Vaccine Safety Datalink – uses medical records of millions to compare vaccinated vs. unvaccinated cohorts for specific outcomes in a controlled way, addressing precisely the under/over-reporting issues).
• Is VAERS intentionally flawed? The article insinuates, without evidence, a motive: that authorities have “left huge defects uncorrected for decades” perhaps intentionally unz.com. This is speculative and not supported by documentation. It’s true that making VAERS mandatory or auditing every report would be challenging. Health authorities have instead developed complementary systems (like VSD, the newer Vaccine Injury Safety Technical (V-Safe) active reporting app, etc.) rather than overhauling VAERS. One could argue whether that’s sufficient, but it’s not correct to imply a nefarious cover-up without proof. No internal documents or whistleblowers are cited to support that claim.

In summary, the factual description of VAERS’s limitations is accurate, but characterizing it as a “deliberate failure to mask harm” is unproven. VAERS data needs cautious interpretation – Turtles is right that it’s “no verification, voluntary, under-reporting” unz.com unz.com. In fact, CDC openly states under-reporting means VAERS cannot be used to calculate true incidence or to compare risk between vaccines and background unz.com unz.com. For example, if 100 people out of 1 million vaccinated had a certain reaction, VAERS might only get a handful of reports. Conversely, if 100 people coincidentally have heart attacks after vaccination, VAERS might attribute all 100, even if only, say, 10 were causally related. Thus, scientists use more reliable datasets to verify safety signals.

Evidence of effect: The article doesn’t mention it, but VAERS has successfully flagged issues in the past – for instance, the early signal of a blood clotting disorder after Johnson & Johnson’s COVID-19 vaccine in 2021 was first detected through VAERS reports, prompting investigation and a temporary pause unz.com unz.com. Rather than concealing problems, the system did surface a rare risk (on the order of a few cases per million) which regulators responded to. This counters the notion that officials intentionally ignore VAERS.

Therefore, we rate the broad claim – that VAERS is unreliable and likely undercounts vaccine harms – as partially accurate. It’s true about reliability limits and under-reporting unz.com unz.com, but the article’s implication of a cover-up goes beyond the facts.

(Additional note: In 2021–2022, anti-vaccine activists heavily cited VAERS numbers for COVID-19 vaccines to claim massive deaths, but these claims were rebutted by showing that no unusual all-cause mortality emerged in vaccinated populations and that VAERS entries weren’t verified causes unz.com. Health authorities emphasize focusing on verified adverse event rates from clinical trials and epidemiologic studies, which have not found evidence of vaccines killing “millions” as some conspiracy theories warned.)

Sources: CDC’s VAERS website and analyses (referenced implicitly) confirm the voluntary nature and known under-reporting. The article’s quotes are accurate excerpts of Turtles critique unz.com unz.com. However, no concrete source supports the claim of deliberate malfeasance – that portion is conjecture. We lean on evidence of how VAERS is actually used by regulators (e.g., detection of the J&J clotting issue – see FDA/CDC press releases) to show that signals are not being uniformly ignored.

3. Claim: Studies questioning vaccine safety (e.g., linking MMR to autism) were “debunked” by flawed or even fraudulent research; raw data actually showed harm

Article’s assertion: The article recounts that in the late 1990s, safety of vaccines (especially MMR) came under question with Andrew Wakefield’s controversial 1998 study in The Lancet unz.com. It then says “the vaccine establishment’s response was to release a series of studies debunking these concerns, studies the Turtles authors argue were flawed, biased, or even corrupt, heavily promoted by media.” It specifically highlights that five major studies were analyzed in Turtles, and some of the “most influential contained errors that severely damage their credibility” unz.com. As a striking example, the article states: “Remarkably, the raw data in one of the most important studies – the 2002 Madsen study of Danish children – actually seemed to support the opposite conclusion (that the MMR did have dangerous side effects), but various dubious statistical ‘adjustments’ were employed to produce the desired reassuring result.” unz.com. In short, the claim is that the evidence dismissing an MMR-autism link was manipulated, and that initial data in at least one large study showed vaccines increased autism risk until researchers allegedly adjusted it away.

Accuracy: Inaccurate. This presentation is misleading and cherry-picked, reviving an old anti-vaccine talking point that has been debunked by independent experts. The “2002 Danish study” mentioned is a well-known population study by Madsen et al. (published in the New England Journal of Medicine) which found no association between MMR vaccination and autism in over 500,000 children. The claim about “raw data showing the opposite” refers to an argument originally made by none other than Andrew Wakefield and later picked up by anti-vaccine writers: they noted that in the crude, unadjusted counts of that study, more vaccinated children had autism than unvaccinated children. However, as epidemiologists have explained, this is because vaccinated children in the cohort were older on average, and autism diagnosis is age-dependent (older kids have had more time to be diagnosed). The study’s authors appropriately adjusted for age and other factors; after adjustment, there was no increased autism risk in vaccinated kids thetransmitter.org thetransmitter.org. Far from being “dubious,” the age adjustment was necessary and scientifically valid. The anti-vaccine blogger who originally pushed this “gotcha” about the Danish data (Jake Crosby) even retracted his critique in 2019, upon realizing that the adjustment was proper and his allegations were unfounded thetransmitter.org thetransmitter.org.

Key points:

• Andrew Wakefield’s study (1998): This was a small case series (12 children) suggesting a link between MMR vaccine and autism/bowel disease. It was fully retracted for unethical methods and data falsification thetransmitter.org. Wakefield was later stripped of his medical license. The article mentions Wakefield to set context unz.com, but it fails to note these crucial facts, instead implying the only reason his claims were “controversial” was because they challenged orthodoxy. In truth, no other researchers could reproduce Wakefield’s findings, and investigative journalism exposed that he manipulated data thetransmitter.org.
• Series of Debunking Studies: After 1998, multiple large-scale studies in different countries (UK, Denmark, USA, etc.) examined the MMR-autism question. All found no link pmc.ncbi.nlm.nih.gov thetransmitter.org. The article, via Turtles, alleges these studies were riddled with bias or even fraud, but provides no concrete examples except the Danish case. It’s a serious charge to call them “corrupt”; independent reviews by the Institute of Medicine (now National Academy of Medicine) concluded by 2004 that the evidence was solid that MMR does not cause autism thetransmitter.org thetransmitter.org. If there were “severe flaws” in the major studies, it’s telling that over two decades, no credible re-analysis has overturned their conclusions. The scientific consensus remains that vaccines are not a causative factor in autism uchealth.org thetransmitter.org.
• The 2002 Madsen (Denmark) study: This is presumably the one referenced. Unz’s article (via Turtles) claims the raw data “actually seemed to support the opposite conclusion… until statistical adjustments produced the desired result”. We investigated this specific claim. In the unadjusted numbers of Madsen et al. 2002, there were indeed more autism cases numerically among MMR-vaccinated children than among unvaccinated children. But crucially, most children in Denmark get MMR, and those who don’t are a small, atypical subset – often younger or with other differences. Autism typically isn’t diagnosed until age 2-3 or later. So any cohort study must adjust for age: if unvaccinated kids tend to be younger (as they were in that dataset, since some were infants not yet eligible for MMR), naturally fewer of them would have an autism diagnosis by the end of study period thetransmitter.org thetransmitter.org. When the data were properly adjusted for age (and sex, etc.), the incidence of autism in vaccinated vs. unvaccinated was statistically the same web.math.princeton.edu. Anders Hviid, one of the study authors, explained: “They say we’re concealing an association with hocus pocus, but it’s just how you should analyze the data… In the raw data, more vaccinated kids have autism because younger kids (not yet vaccinated) haven’t been diagnosed yet.” thetransmitter.org thetransmitter.org. In other words, the Turtles interpretation is a classic failure to understand a basic confounding factor. Adjusting for age was not “dubious” – it was essential to avoid a false conclusion. Notably, even Andrew Wakefield’s own letter in 2004 making this accusation acknowledged that once you account for age, the association disappears thetransmitter.org thetransmitter.org. The anti-vaccine blogger who repeated this claim retracted it and the journal (Annals of Internal Medicine) posted a retraction notice, indicating the critique was baseless thetransmitter.org. This completely undercuts Turtles’ insinuation of foul play in that study.
• Other Studies: The article doesn’t detail others by name, but likely refers to, e.g., the 2004 CDC study by DeStefano et al. (which anti-vaccine activists have also attacked, citing a so-called “whistleblower” who alleged data were omitted – those allegations were investigated and no fraud was found thetransmitter.org). It may also allude to a 1999 UK study by Taylor et al., a 2003 Denmark study by Hviid et al. (same team as Madsen), etc. The pattern is that anti-vaccine circles have tried to cast doubt on each, but their claims have not held up under scrutiny uchealth.org thetransmitter.org. Meanwhile, newer studies (e.g., a 2019 Denmark study of 657,000 children) again confirmed no link – and ironically that 2019 study was also attacked by anti-vaccine activists who misinterpreted data, as described above (the Jake Crosby saga) thetransmitter.org thetransmitter.org.

In conclusion, the claim that the “debunking” studies were themselves fraudulent or that they secretly showed harm is unsupported. On the contrary, the consensus of high-quality evidence shows no causal connection between MMR (or vaccines in general) and autism uchealth.org thetransmitter.org. The Turtles/Unz portrayal is an inversion of reality: it’s the Wakefield camp that engaged in data manipulation (per investigations), and the accusing “raw data” argument is a known misinterpretation. We rate this claim inaccurate.

Sources: The refutation is supported by reporting from The Transmitter (Spectrum News) on the retraction of the anti-vax critique and explanation from the Danish researchers thetransmitter.org thetransmitter.org. Additionally, fact-checking sources and medical literature confirm no vaccine-autism link (e.g., summary by UCHealth stating decades of research show no link uchealth.org). The original 2002 NEJM study (Madsen et al.) and subsequent large studies can be cited to reinforce the lack of association web.math.princeton.edu. The Institute of Medicine (2004) concluded that the evidence “favors rejection of a causal relationship” between MMR and autism. Unz’s article does not engage with these facts, offering instead a conspiratorial narrative – which does not align with the evidence.

4. Claim: No comprehensive “Vaccinated vs. Unvaccinated” health outcomes study has been done – perhaps because it would favor unvaccinated children

Article’s assertion: Unz (summarizing Turtles Chapter 6) claims that “the easiest and most convincing way to demonstrate vaccine safety – a large randomized trial of vaccinated vs. unvaccinated individuals – has never been done. Turtles notes it seems inexplicable that no such study has been initiated for many years.” It points to indications that unvaccinated groups (like the Amish) might have better health outcomes (lower autism, etc.), yet authorities refuse to perform a proper Vaccinated vs. Unvaccinated (VU) study unz.com unz.com. The article then quotes Turtles’ bold conclusion: “There can be only one explanation: The results were markedly in favor of the unvaccinated.” unz.com unz.com. It suggests that perhaps such studies were done quietly and showed vaccines in a bad light, so the data were never released unz.com. In short, the claim is that public health agencies have avoided doing a direct vaccinated vs. unvaccinated comparison of overall health because it would reveal that unvaccinated kids are healthier.

Accuracy: Mostly inaccurate. It is true that a prospective, randomized trial assigning children to completely forgo vaccines vs. get the routine schedule has never been done – for solid ethical and practical reasons. However, the implication that no one has ever studied health outcomes in unvaccinated vs. vaccinated children is false. Several observational studies (retrospective analyses, surveys) have been done – and they do not support the claim that unvaccinated kids are healthier. In fact, unvaccinated children are far more likely to catch and suffer from vaccine-preventable diseases, with no reduction in rates of conditions like autism or asthma once you control for differences in healthcare utilization. The article’s insinuation that authorities “know” vaccines cause net harm and are hiding data is a conspiracy theory without evidence.

Key points:

• Why No RCT? A randomized controlled trial intentionally leaving one group of children unvaccinated for years would be unethical. Vaccines are standard of care; withholding them would put children at clear risk of illness (e.g. leaving kids unprotected from measles, polio, etc. when effective vaccines exist). As early as 2005, the Institute of Medicine reviewed this idea and concluded an RCT would be unethical and unjustifiable unz.com unz.com. This is likely why no such prospective study has been greenlit. The article calls the ethical objection “an obvious nonsense” and suggests alternatives like retrospective studies unz.com unz.com. However, it’s disingenuous to ignore that many retrospective Vax vs. Unvax studies have already been conducted.
• Existing Studies: Contrary to Turtles’ blanket claim that “no study has ever been done by the medical establishment” childrenshealthdefense.org childrenshealthdefense.org, there have been several:
  • A 2004 study in the U.S. compared vaccinated vs. unvaccinated children in an Amish community for rates of autism and found no difference except that the unvaccinated had higher rates of vaccine-preventable infections (this study is often misquoted by anti-vaxxers, but it actually didn’t find zero autism – Amish do have autism cases, and many Amish do vaccinate to some degree) unz.com unz.com. The article’s specific examples (Amish autism rates, Somali immigrants, etc.) come from anecdotal observations or small investigations that are not controlled trials – they are not definitive evidence. For instance, the Somali immigrant autism surge in Minnesota was initially puzzling, but further research pointed to genetic and environmental factors; there was no evidence it was due to vaccines (Somali-American vaccination rates actually dropped after the Wakefield scare, yet autism diagnoses remained high, undermining the vaccine hypothesis).
  • A well-known large-scale study published in 2019 (Glanz et al., JAMA) examined health outcomes in over 2,000 children categorized by vaccine timeliness. It found no indication that “undervaccinated” children were healthier; to the contrary, fully vaccinated children had no higher risk of infections not targeted by vaccines (suggesting vaccines didn’t weaken their immune system) and had far fewer cases of the diseases vaccines prevent childrenshealthdefense.org childrenshealthdefense.org.
  • Two notable papers in 2020–2021 by vaccine skeptics (Miller and Hooker, and Paul Thomas et al.) claimed to find unvaccinated kids had lower rates of conditions like asthma or developmental delays childrenshealthdefense.org. However, these studies were methodologically flawed (non-random convenience samples, etc.) and one was retracted for likely bias in data handling. By contrast, stronger studies show either no differences or that unvaccinated children have higher risks of certain adverse health outcomes (e.g., more hospitalizations from preventable illnesses) childrenshealthdefense.org childrenshealthdefense.org.
• Authorities “suppressing” a VU study: The article asserts without evidence that such a study has “likely been done internally at the CDC” and buried because it would be disastrous for vaccines childrenshealthdefense.org childrenshealthdefense.org. There is zero public evidence for this claim. The CDC did sponsor or conduct some of the above-mentioned studies openly. If a large secret dataset existed showing unvaccinated kids healthier, it would be extremely difficult to hide in the long term. Moreover, other countries’ researchers (with no allegiance to CDC) could and have done such comparisons and found no sign that vaccines cause a general health decline. The Turtles authors’ logic (“only one explanation” – authorities know vaccines fail the test) is a textbook example of begging the question.
• Cherry-picked health metrics: The article focuses on autism rates in the Amish or sibling studies unz.com, implying that unvaccinated groups have less autism. This is anecdotal and possibly due to other factors (e.g., under-diagnosis or different genetic pools). Meanwhile, it ignores the massive, well-documented health benefits of vaccination – for example, unvaccinated children are 22 times more likely to get measles during outbreaks than vaccinated children factcheck.org factcheck.org, and measles can itself cause complications like encephalitis that lead to long-term disability. These concrete benefits aren’t weighed in Turtles’ one-sided suspicion.

In summary, while it’s accurate that no RCT has been done and that public health officials have been reluctant to explicitly compare “fully vaccinated vs. never vaccinated” in a prospective study, the implication that “no one has looked at this” or “unvaccinated are healthier” is unsupported (and contradicted by available data). The reasons no randomized trial occurs are ethical, not conspiratorial. Observational evidence we do have does not show overall better health in unvaccinated kids childrenshealthdefense.org childrenshealthdefense.org – if anything, it shows they suffer more from preventable diseases. We rate the claim that “a comprehensive VU study is avoided because it’d favor unvaxxed” as inaccurate.

Sources: The Children’s Health Defense article actually references that Turtles Chapter 6 states no such study has been done childrenshealthdefense.org and then cites two “private studies” (the Miller and Hooker paper, etc.), which mainstream experts have criticized. The American Academy of Pediatrics and others have published critiques of the notion that unvaccinated kids are healthier, pointing out biases in the few studies that claim that. The Institute of Medicine’s 2013 report also looked at the immunization schedule and found no evidence of harm in the schedule, effectively addressing this concern. Unz’s article does not mention those findings.

5. Claim: Public health improvements (clean water, sanitation, nutrition) – not vaccines – caused the major decline in infectious disease mortality, an “open secret” that vaccines played only a minor role

Article’s assertion: In the section “The Exaggerated Role of Vaccines in Public Health,” Unz summarizes Turtles’ argument that the dramatic declines in infectious disease mortality in the 20th century occurred “long before the introduction of most vaccines or antibiotics”, due mainly to improved public sanitation, hygiene, and nutrition unz.com unz.com. It credits the work of Dr. Thomas McKeown (1960s) for challenging the assumption that medical interventions were responsible unz.com. The article provides charts (from Turtles) showing US infectious disease mortality plummeting from 1900 to 1960, with vaccines like DTP or polio introduced only near the end of that period. It even quotes an Institute of Medicine (IOM) report: “the number of infections prevented by immunization is actually quite small compared with the total number prevented by other hygienic interventions such as clean water, food, and living conditions.” unz.com unz.com. It then alleges that despite these facts being known in scientific circles (“open secret”), the CDC and others still misleadingly credit vaccines as central unz.com unz.com. Turtles concedes that smallpox and perhaps measles morbidity were reduced by vaccines, but portrays those as exceptions unz.com. The overarching claim: Vaccines’ role in the great health gains of the last century is largely a myth – most of the decline happened due to other factors, and experts know this.

Accuracy: Partially accurate (historical data is correct, but interpretation is overstated and context is missing). It is historically true that overall infectious disease mortality rates fell dramatically in the first half of the 20th century, before many vaccines or modern antibiotics were available. Clean water, sewer systems, pasteurization of milk, better housing and nutrition, etc., played a huge role in reducing diseases like cholera, typhoid, TB, and diarrheal illnesses childrenshealthdefense.org childrenshealthdefense.org. Thomas McKeown’s analyses (and subsequent historians like Simon Szreter) indeed demonstrated that social and economic progress was the dominant factor in mortality decline up to WWII scribd.com scribd.com. The IOM quote cited is real and acknowledges that hygienic measures have prevented more infections overall than immunizations childrenshealthdefense.org childrenshealthdefense.org.

However, the article’s implication that vaccines were unimportant or only marginally beneficial is misleading. Vaccines have had a major impact on specific diseases, even if those diseases were causing fewer deaths by the time vaccines arrived. Two important clarifications:

• Mortality vs. Morbidity: The graphs often cited (and presumably in the article) show death rates per 100,000 population. It is true many death rates were declining pre-vaccine. But this was often because of improved medical care and nutrition reducing the fatality of diseases, not necessarily the incidence. For example, measles mortality in the U.S. dropped by the mid-20th century due to better care (fewer children dying of measles), but measles infection was still extremely common – virtually every child caught measles. After the measles vaccine’s introduction (1963), the incidence of measles plummeted by over 90% within a few years factcheck.org factcheck.org, and eventually the U.S. saw zero measles deaths in some years because cases were so few. So while it’s true measles deaths were “near zero” by the 1960s even before the vaccine had a big effect childrenshealthdefense.org childrenshealthdefense.org, that’s partly because cases still occurred but were less fatal; the vaccine then prevented hundreds of thousands of measles cases annually (along with some deaths and complications). Failing to distinguish mortality from morbidity is a common misuse of these statistics. Public health scholars (including the IOM) have noted that vaccines greatly reduced illness burden even if the prior mortality trend was already downward childrenshealthdefense.org childrenshealthdefense.org.
• Vaccines as “founding myth”: The claim that it’s an “open secret” among experts that vaccines had only a minor role is overstated. It’s widely recognized that some diseases were massively curtailed by non-vaccine measures (e.g., typhoid, cholera by sanitation). But other diseases were only controlled through vaccines. For instance:
  • Smallpox: The article concedes smallpox was largely eliminated by vaccine unz.com. In fact, smallpox is unique: it was eradicated globally in 1977 solely by vaccination – a historic triumph.
  • Polio: (Discussed more in Claim 6) – Polio incidence in the U.S. was not declining until the Salk vaccine; the peak was 1952, then the vaccine in 1955 led to rapid decline to near-zero by the 1960s factcheck.org factcheck.org. Improved hygiene did not eliminate polio (in some ways it made it more paradoxical, as we discuss later). So polio is another case where vaccine was critical.
  • Measles: As noted, measles cases and associated complications dropped precipitously after vaccination. The chart referenced in the CHD article shows measles deaths were very low by 1960 (maybe ~1 per 100,000), but measles cases were hundreds of thousands annually. After the vaccine, measles cases in the U.S. fell by 99% and endemic transmission was declared eliminated in 2000 factcheck.org factcheck.org. Turtles acknowledges vaccines reduced measles “widespread illness (morbidity) if not mortality” unz.com – that is a significant contribution, not a trivial one.

So, the factual historical data is correct that sanitation and other non-vaccine interventions were the main drivers of the huge mortality decline from ~1900 to 1940s scribd.com scribd.com. Vaccines for diseases like diphtheria (late 1940s) and polio (mid-1950s) came after much of the baseline risk had declined – but they then finished the job of virtually eliminating those diseases (something sanitation alone couldn’t do for infections that weren’t water/food-borne).

The Institute of Medicine quote (from 2000 or 2002) is taken slightly out of context but is essentially noting that by the late 20th century, vaccines prevent a smaller fraction of total infections compared to those prevented by sanitation, etc., across the board childrenshealthdefense.org childrenshealthdefense.org. This is plausible because sanitation affects many diseases broadly, whereas vaccines target specific diseases. However, that doesn’t diminish the fact that for those specific diseases, vaccines were often decisive in eradication or near-eradication (e.g., diphtheria, measles in some regions, rubella, etc.). Public health experts do acknowledge this “open secret” in academic circles – it’s part of public health history curricula. The CDC, while it does celebrate vaccines (especially in communication to the public), also regularly emphasizes clean water, nutrition, etc., as crucial health interventions. It’s not really a conspiracy of silence; it’s more about public messaging focusing on what people today can do (vaccinate) versus crediting past infrastructure (since we already have clean water).

Therefore, we rate the claim partially accurate: Correct that much decline in disease mortality was due to socio-environmental improvements, and vaccines are sometimes over-credited in simplistic narratives. But the article goes too far in minimizing vaccines’ contributions. Vaccines played a crucial role in reducing the incidence of many diseases (and thereby preventing morbidity and some mortality that sanitation alone couldn’t prevent – you can’t purify air to stop measles or whooping cough, for example). It’s false to call vaccines’ role a “foundational myth” of public health – more a part of a larger puzzle of progress scribd.com scribd.com.

Sources: McKeown’s work is summarized in sources like Szreter 1988 (cited in Turtles) scribd.com scribd.com. The American IOM (2002) quote is confirmed in the Children’s Health Defense article childrenshealthdefense.org childrenshealthdefense.org. Fact-checkers have addressed memes that use old mortality charts to dismiss vaccines: for example, PolitiFact rated “vaccines didn’t save us, sanitation did” as Half True, noting both elements are important politifact.com. We echo a similar nuanced conclusion.

6. Claim: The polio narrative is deeply flawed – polio’s rise was mysterious, possibly caused by toxins like pesticides; the polio vaccine’s role in ending polio is overstated or even a ‘sleight of hand’ by redefinition

This multifaceted claim from the article challenges the canonical story of polio. Key points made:

• Polio’s emergence and pattern were bizarre: Polio outbreaks started in late 19th century (unlike many diseases around for millennia) and were confined to industrialized countries, hitting in summer and often affecting affluent youth unz.com unz.com. It notes instances like Americans in the tropics getting polio while locals didn’t, or British officers in India having higher polio rates than enlisted men unz.com unz.com – suggesting hygiene or lifestyle factors. The article implies these mysteries were never resolved unz.com unz.com.
• Contradictory assumptions on polio’s cause: Early on it was thought a disease of poverty (urban slums) – later a disease of cleanliness/affluence – then in the 3rd World returned to affecting the poor unz.com unz.com. This is presented as evidence that the true nature of polio was misunderstood fundamentally unz.com unz.com.
• Polio paralysis could have non-viral causes: The article (via Turtles) asserts “flaccid paralysis” had up to 200 different possible causes (poisons, toxins) and that the label “polio” was over-applied to any paralysis by the early 20th century unz.com unz.com. It cites an example: in the 1890s, lead arsenate pesticides began use in US orchards, and a polio outbreak around Boston in 1893 disproportionately hit rural areas during apple harvest season, with symptoms similar to lead poisoning unz.com unz.com. It says doctors at the time admitted difficulty distinguishing poliomyelitis from toxic nerve damage, hinting that many “polio” cases might have been poisonings misdiagnosed unz.com unz.com. It also references a 1900 Manchester, England epidemic of paralysis traced to arsenic-contaminated beer, and a 1930 US outbreak where 50,000 were paralyzed by a toxic adulterant in a patent medicine (these are real incidents, but not polio) unz.com unz.com. The notion is that some – perhaps much – of what we called polio was actually environmental toxin-induced paralysis.
• Polio virus causation in doubt: The article stops short of fully denying the virus, but asks “is polio really an infectious disease? … Early critics found no examples of person-to-person transmission; cases were so scattered (only <3% of households had multiple cases)” unz.com. It notes attempts to infect animals orally failed, etc., implying the virus theory had gaps unz.com unz.com. It quotes Turtles’ “restrained” hint: “The supposition that polio is an infectious and contagious disease … is cast in concrete, and any scientist daring to challenge it is ignored or mocked. But is it really so straightforward?” unz.com unz.com.
• DDT and polio: The article strongly suggests a connection with pesticides. It says polio rose dramatically exactly as new chemicals like arsenic and later DDT came into widespread use unz.com unz.com. It points out the first big U.S. polio outbreaks were in the 1910s–1950s when hygiene improved but also lead/arsenic pesticides and later DDT were used heavily unz.com unz.com. It notes some 1940s experts observed polio spikes tracking summer pesticide spraying, but authorities denied a link unz.com unz.com. The article implies DDT (peaking in late 1940s-50s) might have contributed to polio incidence, and that the decline of polio in the 1960s could partly be due to reduced DDT use (it claims American agencies quietly curbed DDT in early 1950s, before the official 1972 ban) unz.com unz.com.
• Polio vaccine efficacy questioned: While acknowledging the Salk vaccine came in 1955 and polio cases dropped, the article argues this cause-effect is not so clear. It says polio cases were already sharply declining for several years before Salk’s vaccine, and that after vaccinations began, there was a “noticeable rise” a few years later in polio incidence (possibly referring to a late-50s uptick or Sabin live vaccine causing some cases?) unz.com unz.com. It specifically cites Israel’s data: a long decline pre-vaccine, then polio went up after vaccination started in 1957, then down again unz.com. This is presented as contradictory to a simple vaccine-saves-all story.
• Redefinition of Polio vs. AFP: Finally, the article states that global vaccination wiped out reported polio by 2013 (99.9% drop in cases) but simultaneously “Acute Flaccid Paralysis” (AFP) rates skyrocketed – suggesting that severe paralysis cases might still be happening just labeled differently unz.com unz.com. It implies that the success of polio eradication might be, quote, “achieved merely by redefinition, a sleight of hand” unz.com unz.com. Essentially, that we didn’t so much eliminate paralysis as we changed what we call it.

This is a lot to unpack. We break down accuracy in parts:

Polio’s epidemiological mysteries (industrialized countries, higher socio-economic groups): Mostly accurate contextually. It’s true polio (specifically paralytic poliomyelitis) became epidemic only in the late 19th/early 20th century, mainly in Europe and the U.S., puzzling experts. And yes, better-off groups were hit more in mid-20th century – what we now understand as the “hygiene hypothesis” for polio: In earlier eras, children were exposed to poliovirus in infancy (via contaminated water, etc.) while protected by maternal antibodies, so they developed immunity without paralysis. With improved sanitation, infants weren’t exposed, so the virus struck older children/teens with no immunity, leading to more paralytic cases unz.com unz.com. This is a well-accepted explanation factcheck.org factcheck.org. The article doesn’t mention it explicitly, instead implying it’s inexplicable – but in fact, by mid-20th century, epidemiologists had identified this phenomenon (personified by the phrase “polio is a disease of development”). Example: American soldiers and Westerners in developing countries lacked childhood immunity that local populations often had, so Westerners were more susceptible – exactly what Turtles notes unz.com unz.com. This wasn’t an unsolvable mystery; it was evidence that polio was indeed infectious and widespread, just usually causing mild illness at young ages. So the article’s facts are right, but it leaves out that there is a coherent explanation involving the virus’s transmission and immunity patterns factcheck.org factcheck.org.

Labeling every paralysis as “polio”: Partially accurate but exaggerated. It’s true that “polio” (meaning gray matter of spinal cord inflammation) was a diagnosis sometimes given without lab confirmation in the early 20th century. Some cases of paralysis from other causes may have been lumped in. However, by the 1940s-50s, diagnostic criteria for poliomyelitis were refined and viral tests (throat/stool cultures) started to be used. The article is correct that some paralysis outbreaks had other causes (the arsenic-in-beer in Manchester 1900, the Jamaica Ginger paralysis in 1930). But these were recognized at the time as not polio. The 50,000 paralysis cases in 1930 were due to tri-ortho-cresyl phosphate (TOCP) contamination in a bootleg ginger tonic (a tragic mass poisoning); doctors quickly traced it and didn’t confuse it with infectious polio unz.com unz.com. So while Turtles implies such events were misdiagnosed as polio, history shows they were identified as toxic neuropathy (not counted in polio stats). The example of lead arsenate pesticide in 1893 and polio cases near Boston is intriguing but anecdotal. There’s no rigorous evidence that those cases were chemical poisonings; it’s a hypothesis from some observers. Modern historians note the difficulty in retrospect, but there’s no consensus that “most polio was poison.” The virological evidence is strong: poliovirus was isolated in 1908 factcheck.org, and by the 1950s, it could be seen under microscope and grown in culture factcheck.org factcheck.org. Polio outbreaks correlated with finding the virus in patients; alternative causes like toxins wouldn’t explain why the virus was consistently present. So this claim is largely unsupported. (We’ll address DDT separately below, as it’s a specific toxin hypothesis.)

Polio virus transmission doubts: The article cites that less than 3% of cases had multiple in a family unz.com, which is true – poliovirus would infect many in a household, but paralysis occurred in a small fraction (~1 in 200 infections). So most family members might have asymptomatic or mild infections, not recognized as polio, and only one becomes paralyzed. Early investigators who looked only at paralytic cases might mistakenly think it didn’t spread person-to-person because they didn’t see multiple paralyses in one home. Today we know silent transmission was common factcheck.org factcheck.org. The difficulty infecting lab animals was also true – polio is very host-specific to humans (and some primates). These facts were perplexing at the time but don’t invalidate the virus theory; they just required deeper understanding (which we have now). So the doubt cast (“is polio really infectious?”) is not justified by current knowledge – we have abundant evidence it is (human-to-human via fecal-oral route) factcheck.org factcheck.org.

Polio & DDT/Toxins: Inaccurate. This is a long-standing myth in anti-vaccine/anti-pesticide circles: that DDT or other chemicals caused polio or “polio-like” illness. Extensive fact-checking has debunked this:

• Polio existed before pesticides like DDT. Polio outbreaks were recorded in the 1880s–1890s (and isolated cases even earlier). DDT was first synthesized in 1874 and only used widely in the 1940s factcheck.org factcheck.org. The virus itself was identified in 1908 factcheck.org. There’s no evidence of paralytic outbreaks in areas simply correlated with pesticide use beyond coincidence. No scientific study has ever proven that DDT causes polio. AP News and FactCheck.org both concluded there’s no causal link – polio is caused by poliovirus, not chemicals factcheck.org factcheck.org. Indeed, at the height of U.S. polio in the 1940s-50s, DDT was being sprayed in hopes to stop polio (people mistakenly thought mosquitoes or flies spread polio, so they sprayed insecticide) factcheck.org factcheck.org. That obviously didn’t work, but it shows authorities didn’t think DDT was causing polio – they thought it might help stop it (they were wrong about vector, but DDT wasn’t making it worse). The article’s suggestion that American health agencies quietly limited DDT in the early 50s to reduce polio is not supported by historical records; widespread DDT spraying continued into the 1960s until environmental concerns grew (polio had been already beaten by vaccine) factcheck.org factcheck.org.
• Timeline mismatch: Polio in the U.S. peaked ~1952 with ~58,000 cases factcheck.org factcheck.org. DDT usage peaked later, in 1959 ( ~80 million lbs) factcheck.org factcheck.org. If DDT caused polio, one would expect polio to keep rising through the late 50s with peak DDT; instead it crashed after 1955 due to vaccines factcheck.org factcheck.org. After DDT was banned (1972), there was no resurgence of polio-like illness – U.S. polio didn’t return.
• Expert consensus: “Experts say toxic pesticide DDT not linked to polio” (AP News) apnews.com. The virology community emphasizes poliovirus’s role – the virus meets Koch’s postulates essentially (monkey experiments as early as 1908 produced paralysis by injecting filtered virus factcheck.org factcheck.org). No such controlled evidence exists for DDT causing the same pathological lesions as polio.

Therefore, the claim that polio was largely poisonings miscast as viral is baseless. It’s a fringe theory not accepted by medical historians or virologists factcheck.org factcheck.org.

Polio vaccine effect vs. natural decline: The article’s assertion that polio was already declining before the vaccine is misleading. Polio incidence was volatile year to year, but the overall trend in the 1940s-early 50s was worsening, not improving. The U.S. had big epidemics in 1944, 1949, 1952 (the worst) factcheck.org factcheck.org. 1953 and 1954 saw fewer cases than 1952, but still high. When Salk’s vaccine came in 1955 and a nationwide campaign ensued, cases plummeted by ~90% in just a few years factcheck.org factcheck.org. That far exceeds any pre-vaccine oscillations. The “rise a few years later” likely refers to the late 50s when the less-effective Salk killed vaccine was transitioning to Sabin’s oral vaccine – there were some upticks in 1958-59 in certain countries before the oral vaccine was widespread. In Israel, indeed, vaccination started in 1957 with Salk but a significant outbreak occurred in 1958-59; only after switching to Sabin OPV in early 1960s did polio vanish there unz.com. This doesn’t prove vaccines didn’t work – rather it suggests the initial campaign missed some or that the live vaccine was needed for better immunity. So contextually: the global data overwhelmingly show vaccination correlates with polio’s demise factcheck.org factcheck.org, notwithstanding a couple of transitional bumps.

Acute Flaccid Paralysis (AFP) “sleight of hand” claim: Mostly inaccurate. It is true that the Global Polio Eradication Initiative tracks “non-polio AFP” cases. In India and other places, thousands of AFP cases (which include Guillain-Barré syndrome, other enterovirus paralyses, etc.) are reported yearly – partly because surveillance was greatly intensified to find any paralysis, and every case is tested to see if polio virus is present virologydownunder.com virologydownunder.com. The increase in reported AFP is largely due to this heightened surveillance and a broad definition (any acute flaccid paralysis, from any cause). It is not the same as polio. For example, India in 2011 had over 59,000 AFP cases reported, but none were polio – all samples tested negative for poliovirus downtoearth.org.in downtoearth.org.in. That doesn’t mean 59,000 children had “hidden polio” – they had other conditions (like Guillain-Barré, which can occur at a rate of 1-2 per 100k children annually, and India’s huge population yields thousands of such). Some critics (Puliyel et al.) hypothesized that excessive OPV doses might have caused some AFP; their analysis was contested and even if true, would apply to a small fraction of cases pmc.ncbi.nlm.nih.gov pmc.ncbi.nlm.nih.gov. Overall, the total paralysis cases (from all causes) in India did not increase after polio vaccination – they actually have started to decrease in recent years after peaking when OPV use was highest pubmed.ncbi.nlm.nih.gov pmc.ncbi.nlm.nih.gov. There is no evidence that the polio eradication is a mirage – wild poliovirus paralysis has truly been eliminated in India (last case 2011), and nothing equally bad has replaced it. Non-polio AFP includes many mild/transient paralyses as well.

The claim of “sleight of hand redefinition” is a talking point that fact-checkers have labeled false publichealthcollaborative.org publichealthcollaborative.org. It implies a grand deception, but global health data is transparent: even with those AFP cases, the most devastating form of paralysis – poliomyelitis – is 99.9% gone unz.com unz.com. If the same number of children were paralyzed by something else, we would see it (and we don’t see tens of thousands of kids in leg braces or iron lungs from other causes). Notably, after India eliminated polio, its childhood paralysis rates dropped significantly within a few years, suggesting many “AFP” cases were indeed polio that just hadn’t been confirmed or were on the verge of being polio livemint.com downtoearth.org.in.

Conclusion on this claim: The article mixes some valid history (sanitation paradox of polio, misdiagnoses in early times) with a large dose of unsupported conjecture. The core suggestion that polio was not really beaten by vaccines but by stopping toxins or by relabeling AFP is inaccurate. Poliovirus is the proven cause of polio, and vaccination campaigns did eliminate polio in the Americas, Europe, etc. factcheck.org factcheck.org. The polio vaccine’s success is well-documented, not a myth. That said, the history of polio does have nuances: e.g., the Salk vaccine had to be followed by Sabin’s to finish the job; and other factors like better medical care reduced polio’s fatality over time (in 1910s, many died; by 1950s, more survived with disability).

We rate the broad claim that “polio was perhaps not viral but toxic, and the vaccine triumph is suspect” as false. The evidence for poliovirus causation is overwhelming factcheck.org factcheck.org. The vaccine’s role in ending epidemics is clear in epidemiological graphs (the drop in cases is coincident with vaccine introduction, not with toxin bans) factcheck.org factcheck.org. And although AFP surveillance numbers are high, experts explain that as an artifact of intensive monitoring, not secret polio virologydownunder.com virologydownunder.com.

Sources: FactCheck.org’s detailed refutation of the “DDT caused polio” and “polio decline was due to DDT ban” claims factcheck.org factcheck.org is directly relevant. AP News and PolitiFact have similar pieces apnews.com politifact.com. Virology Down Under’s article addresses the AFP misinterpretation in India virologydownunder.com virologydownunder.com. These authoritative sources strongly contradict the article’s speculations.

Finally, it’s worth noting that this section of Unz’s article heavily relies on Turtles All the Way Down, which presents a contrarian hypothesis on polio. That hypothesis has not been vetted in peer review and runs counter to historical scholarship. In evaluating credibility (next section), we’ll see that mainstream science and history do not support these radical revisions of the polio story.

7. Claim: COVID-19 mRNA vaccines were rushed and potentially dangerous, with authorities suppressing alternatives (HCQ/IVM) to justify emergency use

Article’s assertion: In the introduction, Unz mentions that the 2020 COVID pandemic led to “massive roll-out of mRNA vaccines, rushed without the usual years of trials”. It says given the new mRNA technology (hijacking cells to produce spike protein) and lack of long-term testing, it’s unsurprising many were fearful unz.com. He references “plausible claims that the media campaign against HCQ and IVM (hydroxychloroquine and ivermectin) was orchestrated to ensure no effective alternatives, thus allowing emergency authorization of vaccines”, and notes the vaccine manufacturers made huge profits, “provoking reasonable suspicions of cynical observers” unz.com unz.com. He also cites how by 2021, anti-vaxxers on his site predicted the mRNA vaccines would “kill millions—or even billions (as part of a Bill Gates depopulation plot)”, which he himself thought was lunacy unz.com unz.com. He concludes that after two years of data, it appears those extreme fears were mistaken: “number of non-elderly vaccine deaths seems almost invisibly low, too small to notice in mortality stats” and that waves of youth sudden deaths were more likely due to COVID infections than vaccines unz.com unz.com. Still, he allows that long-term harms from mRNA shots aren’t impossible but so far there’s little evidence of such unz.com.

This is a mix of claims: (a) COVID vaccines were rushed without normal trials; (b) authorities possibly suppressed HCQ/IVM to clear the way for vaccines; (c) vaccine companies profited hugely, raising suspicion; (d) anti-vax predictions of mass death were wrong; (e) data shows vaccines did not cause a detectable spike in mortality in 2021; (f) perhaps COVID infections themselves cause more of the “sudden deaths” than vaccines.

Accuracy: Mostly accurate, with some caveats. Let’s break it down:

• “Rushed without usual years of trials”: The COVID mRNA vaccines (Pfizer & Moderna) were developed and authorized in under a year, which is unprecedented speed. However, they did undergo clinical trials – Phase I, II, and large Phase III trials with tens of thousands of participants were completed in 2020, albeit on an accelerated timeline unz.com. What was bypassed was the long follow-up; normally vaccines might be observed in trials for 2+ years, but due to the emergency, they had a median ~2 months follow-up at time of EUA. This is a valid point – long-term efficacy and rare side effects couldn’t be known at rollout. Regulators balanced that against the pandemic’s toll. So yes, “rushed” is fair, though not “untested” (they were tested in tens of thousands and shown efficacious and relatively safe in short term) unz.com unz.com. This was openly acknowledged by health officials (hence intense monitoring after rollout).
• Suppression of HCQ/IVM for EUA: It’s true that under U.S. law, an Emergency Use Authorization (EUA) for a new vaccine requires that no adequate approved alternatives exist unz.com. The article implies a conspiracy that media/government “orchestrated” negative press on hydroxychloroquine and ivermectin to ensure vaccines were the only option unz.com. This is unproven and largely speculative. While it’s true those drugs were touted by some and studies were conflicting, by late 2020 most robust trials showed no clear benefit of HCQ or IVM in treating COVID-19 unz.com (e.g., large RECOVERY trial for HCQ was negative). It wasn’t a mere media campaign; many scientists concluded these were not effective treatments (especially HCQ, which was studied extensively). The EUA could still be granted even if those were under investigation, because they were not proven effective. There’s no evidence of a coordinated “suppression” beyond normal scientific debate and the desire to prevent people taking unproven meds. So this claim is conspiratorial. We mark it unsubstantiated. (Notably, many countries tried using HCQ/IVM widely – it didn’t stop their COVID waves).
• Vaccine manufacturer profits: Yes, Pfizer, Moderna, etc., made tens of billions from the vaccines. That is factual (Pfizer’s 2021 COVID vaccine revenue was over $36 billion). This indeed led to public cynicism. The article calls that “reasonable suspicion” unz.com. One can debate if profit motives influenced policy (e.g., intellectual property issues), but the raw fact of huge market value increase is correct.
• Anti-vax “kill millions/billions” prediction: Sadly, some extreme anti-vaccine voices did claim the COVID vaccines would cause mass deaths or infertility (the article notes Bill Gates depopulation theory) unz.com unz.com. As of mid-2023, no such mass deaths have occurred. Global excess mortality data do not show a wave of death corresponding to vaccine rollouts; quite the opposite, death rates fell as vaccines curbed the pandemic unz.com unz.com. So Unz is correct to label those predictions as “stark raving lunacy” (his words) and note that two years in, evidence doesn’t support a catastrophic safety issue unz.com unz.com. This aligns with consensus: the vaccines have rare serious side effects (like myocarditis in young males, about 1 in 5,000 – treatable; rare thrombosis with J&J) but not large-scale mortality unz.com unz.com.
• No noticeable mortality increase from vaccines: Studies and health agencies have looked at all-cause mortality and specific outcomes. There has been no signal of overall mortality being higher among vaccinated vs. unvaccinated populations; on the contrary, COVID vaccines saved an estimated 20 million lives globally in 2021 unz.com unz.com. The article points out that non-elderly death rates in 2021-22 did not spike beyond what can be attributed to COVID itself – and attributes “sudden deaths in athletes” more to COVID after-effects than to vaccines unz.com. This is a reasonable interpretation: e.g., some unexplained cardiac deaths could be due to silent heart damage from COVID infection (which is known to cause myocarditis at a higher rate than vaccines do) unz.com. Indeed, a peer-reviewed study in Circulation 2022 found young athletes were more likely to collapse from COVID-related heart issues than from vaccine myocarditis unz.com. So Unz’s stance here is evidence-based and differs from many anti-vaxxers – he’s acknowledging the apocalypse did not occur and aligning with data.
• Long-term unknowns: He cautiously notes we can’t completely rule out long-term effects (true – we are only 2-3 years out), but so far no evidence of such unz.com. This is fair.

So, taken together: the article’s portrayal of the COVID vaccine situation is mostly accurate and even-handed compared to the other claims. The only dubious part is the insinuation of a deliberate suppression of alternative treatments to pave way for vaccines – that remains a conjecture without hard proof (and mainstream analysis suggests those treatments just didn’t pan out in trials).

We rate this set of claims mostly accurate, with a caution that the “orchestrated campaign” claim is not substantiated by evidence (thus leaning into partially accurate for that sub-claim). The actual outcomes – vaccines not causing mass death, and likely being net beneficial – are correctly stated unz.com unz.com.

Sources: Numerous studies: HCQ/IVM – large RCTs (RECOVERY trial, TOGETHER trial, etc.) showed no major benefit for HCQ, mixed for IVM (likely no large effect). Vaccine safety – CDC monitoring (VAERS, VSD) found rates of myocarditis ~5-10 per 100k in young males, but treatable; no uptick in overall youth mortality unz.com. Excess mortality data from 2021 attribute the majority of excess deaths to COVID itself, with higher excess in less vaccinated regions, indicating vaccines helped reduce deaths unz.com. So evidence aligns with Unz’s tempered view that extreme fears were unfounded. Even OpenVAERS (often cited by anti-vax) listing ~15k US VAERS death reports must be interpreted with caution – studies have checked and found no causal pattern; the vast majority occurred in elderly people, consistent with background death rates unz.com.

In conclusion, Unz’s statements on COVID vaccines are largely backed by evidence, aside from the suggestion of intentional suppression of early treatments, which is speculative. He actually provides a model of how someone initially wary might update their views given real-world data – that’s a positive example of following the facts.

(As an aside: The credibility of those raising alarms – e.g., RFK Jr. calling COVID vaccines a genocidal plot – has suffered as their dire predictions failed. Unz distances from the “militant anti-vaxxers” on this point unz.com unz.com, which is noteworthy.)

Source Representation Analysis

Ron Unz’s article heavily draws on alternative and anti-establishment sources, so it’s vital to assess whether these sources are used accurately and whether they are credible:

• Use of “Turtles All the Way Down: Vaccine Science and Myth”: This anonymous book is the backbone of Unz’s essay. Unz explicitly says he is summarizing the authors’ arguments without fully endorsing them unz.com. However, in doing so he often takes the book’s claims at face value. We found that Turtles presented some factual information correctly (historical data, VAERS description) but also omitted context or skewed interpretations (e.g., the Danish MMR study, polio causation). Unz relayed these skewed points uncritically. For instance, Turtles states “not a single vaccine dose given to infants has been tested against inert placebo” voxday.net; Unz passes this on, but as we noted, that is a sweeping generalization that isn’t entirely true. He did not mention contrary examples or the ethical rationale, leaving the reader with a one-sided view. Similarly, the polio chapter of Turtles is controversial and largely speculative – Unz reproduces its argument in detail. There is no evidence he cross-checked these claims with independent historical research. This constitutes a form of cherry-picking: he uses a source that aligns with a contrarian narrative and doesn’t provide mainstream counterpoints.
• Children’s Health Defense / RFK Jr.: Unz references RFK Jr.’s book “The Real Anthony Fauci” and its HIV/AIDS claims unz.com unz.com, as well as CHD being the publisher of Turtles’ American edition unz.com unz.com. RFK Jr. and CHD have a clear agenda and history of misrepresenting science (e.g., promoting discredited links between vaccines and autism, or lately the unfounded claim HIV doesn’t cause AIDS). These are not authoritative sources on biomedical topics. Unz treats RFK Jr.’s HIV book as stunning but plausible, even though the scientific community rejects its thesis. This indicates a credulity toward low-credibility sources. By contrast, he rarely cites, say, the WHO or major medical journals except via critical commentary. This imbalance can mislead readers about the weight of evidence. For example, Unz says mainstream media attacked RFK Jr. “on other grounds” but stayed silent on his AIDS chapters, implying those chapters are valid unz.com unz.com. In reality, scientists likely found those chapters too baseless to merit response – silence is not tacit agreement. Unz’s interpretation is skewed to favor the CHD/RFK narrative without proper scrutiny.
• The Unz Review itself & Kevin Barrett’s interview: Unz cites his own prior articles (on COVID vaccine mortality) as evidence unz.com, which is somewhat circular. He also cites an audio interview by Kevin Barrett with Zoey O’Toole unz.com. Kevin Barrett is a known conspiracy theorist (9/11 truther, etc.), not a medical expert. Including that indicates the echo chamber nature of the sources – alternative media interviewing each other. It doesn’t lend external validation to Turtles’ claims, it just shows they’re circulating in the same niche circles. This undermines source rigor.
• Globalresearch.ca and BitChute references: In a footnote, Unz lists a GlobalResearch.ca article claiming “thousands of miscarriages from COVID vaccines” and a BitChute video claiming “billions” would die unz.com unz.com. He does this to illustrate what the extreme anti-vaxxers on his site were saying. To his credit, he distances himself from those claims (calling them lunacy) unz.com. However, including those links at all directs readers to highly unreliable sources known for propaganda and misinformation. This could inadvertently amplify those fringe claims. It also illustrates that some of Unz’s audience and contributors rely on notoriously non-credible outlets. While Unz himself didn’t endorse those claims, the fact they were prominent on his site speaks to The Unz Review’s lack of editorial rigor in filtering out false information.
• Institute of Medicine and Wikipedia citations: Interestingly, Unz/Turtles do cite mainstream references occasionally (IOM report, Wikipedia on polio vaccine, etc.) unz.com unz.com. The IOM quote was accurate childrenshealthdefense.org childrenshealthdefense.org, but context wasn’t fully given (it was used to imply “open secret” of vaccines’ minor role). Using a snippet from a reputable source to bolster a broader anti-vaccine narrative is a form of contextual misuse. The Wikipedia footnote on polio vaccine probably was to reference the standard story ironically while setting up the contrarian take unz.com unz.com. That’s acceptable, but not substantive.
• Misquoting / Misrepresentation: The Danish MMR study is a clear case of misrepresentation. Unz wrote that the raw data supported an opposite conclusion until “dubious adjustments” were made unz.com. We showed that adjustments were actually appropriate and not dubious thetransmitter.org thetransmitter.org. Here, Unz (via Turtles) misrepresents the source (Madsen 2002 study) to imply malfeasance where none existed. That crosses into misinformation. Similarly, presenting the polio vaccine as possibly a “sleight of hand” by pointing to AFP data is a misleading use of surveillance stats, which experts explicitly warn against virologydownunder.com virologydownunder.com. Unz likely took Turtles’ analysis at face value here, but in doing so, he propagated a distortion of the source data’s meaning.
• Credibility of individuals: Unz relies on voices like Andrew Wakefield (he mentions Wakefield’s 1998 paper neutrally as “hugely controversial” unz.com, not explaining it was fraudulent). That gives an undeserved aura of legitimacy to a discredited figure. Likewise, his extensive positive treatment of RFK Jr.’s arguments on AIDS – calling the book “stunning” and concluding RFK Jr. was “probably correct” unz.com unz.com – shows a failure to critically assess credibility. The mainstream view is that the Duesberg HIV/AIDS theory RFK echoes has been thoroughly disproven (e.g., South Africa’s experiment with denying HIV treatment led to hundreds of thousands of deaths unz.com). Unz doesn’t mention the overwhelming scientific consensus on HIV, instead suggesting RFK Jr. might be right. This is a major factual and ethical lapse, given the harm of AIDS denialism. It demonstrates how Unz gives alternative sources undue weight and downplays scientific consensus, potentially misleading readers about life-and-death topics.

In sum, Unz’s source usage is selective and biased towards the contrarian viewpoint. Legitimate sources are either omitted or mined for quotes that support his narrative, while dubious sources are given sympathetic treatment. The article does not provide the reader with a balanced representation – for each claim, it leans on one side (usually the fringe interpretation) without fairly presenting the robust counter-evidence or mainstream perspective. This is ethically problematic in an article purporting to reveal the “truth,” as it can reinforce misinformation under the guise of critical inquiry.

The platforms (The Unz Review, CHD) and individuals (RFK Jr., Wakefield, etc.) cited have strong anti-establishment agendas and a record of spreading misinformation. Unz not only cites them but often concurs (except on the most extreme COVID claims). He rarely challenges their accuracy, which lowers the reliability of the article’s content.

Conclusion

In conclusion, Ron Unz’s “Vaccines and the Mystery of Polio” blends valid historical observations with unsupported conspiracy theories and misrepresented data. Our fact-check finds that many of the factual claims in the article are either partially accurate or outright inaccurate when put in proper context:

• It is true that improvements in sanitation and nutrition were paramount in reducing infectious disease mortality long before vaccines for those diseases existed childrenshealthdefense.org childrenshealthdefense.org. However, the article downplays the critical role vaccines played in later controlling or eliminating specific illnesses like polio, measles, and smallpox, which history and data credit largely to vaccination campaigns factcheck.org factcheck.org. The “foundational myth” of vaccines freeing us from all past disease is overstated, but conversely, claiming vaccines only provided a “minor” benefit is a distortion childrenshealthdefense.org childrenshealthdefense.org.
• Vaccine safety concerns raised (lack of inert placebos in trials, reliance on VAERS reporting) have a basis in fact, but the article’s insinuation of deliberate malpractice is unfounded. Clinical trial designs and safety monitoring are imperfect, yet there is extensive evidence that vaccines on the schedule have favorable safety profiles when studied with rigorous methods beyond VAERS childrenshealthdefense.org childrenshealthdefense.org. Unz’s source (Turtles) highlighted real issues (e.g., active comparators in trials voxday.net voxday.net) but then leapt to alarmist conclusions unsupported by broader evidence (e.g., “flying blind” means disaster is looming, which has not manifested in reality).
• The MMR-autism allegations are a clear case where the article misrepresents the evidence. The studies rebutting Wakefield were not fraudulent – multiple large studies consistently found no link pmc.ncbi.nlm.nih.gov thetransmitter.org. The supposed revelation about the Danish study is based on a misunderstanding of epidemiology thetransmitter.org thetransmitter.org. Here, Unz relies on a discredited narrative, misleading readers into thinking a cover-up occurred, whereas in truth the only fraud was Wakefield’s study itself.
• The polio revisionism presented is highly misleading. While it asks intriguing questions about polio’s unique patterns (questions researchers actually answered decades ago), it ultimately promotes a debunked narrative that toxins or misdiagnosis caused polio. Our review shows the scientific consensus and historical record strongly support poliovirus as the cause of polio and vaccines as the driver of its eradication factcheck.org factcheck.org. The increase in “acute flaccid paralysis” reports post-polio is a known surveillance artifact, not evidence that polio cases were merely re-labeled factcheck.org virologydownunder.com.
• On COVID-19 vaccines, Unz’s analysis is more aligned with reality: he correctly notes that apocalyptic predictions by some anti-vaxxers did not come true and that data do not show a wave of vaccine-caused death unz.com unz.com. However, his suggestion of a conspiracy to suppress treatments for EUA is speculative. Overall, his portrayal of COVID vaccine safety (aside from that conspiracy hint) is reasonable and fact-based, acknowledging both public fear and the ultimate evidence of vaccine safety/efficacy.

Source Usage and Ethical Considerations: Unz’s piece uses a mix of reliable data and dubious sources, but often frames information to fit a narrative of pervasive vaccine dangers or historical cover-ups. The cited sources are frequently not represented in fair context – e.g., quoting the IOM out of context to suggest scientists “know vaccines did little” childrenshealthdefense.org childrenshealthdefense.org, or citing a Wikipedia fact only to undermine it with conjecture. The article leans heavily on one book (Turtles) and commentary from known anti-vaccine activists, while ignoring the vast body of mainstream research that contradicts those claims. This is a form of selection bias that can mislead readers who aren’t aware of the broader evidence.

Credibility of Platforms: The Unz Review markets itself as “alternative media” and indeed provides space for contrarian views, but readers should know it lacks fact-checking filters found in traditional journalism. It often features content that mainstream science would deem conspiracy-driven or unsupported, and this article is no exception (especially on polio and HIV/AIDS claims). Children’s Health Defense and its authors (like RFK Jr. and Zoey O’Toole) have a clear anti-vaccine agenda and a track record of cherry-picking studies to sow doubt about vaccines; their work is not considered reliable by the scientific community thetransmitter.org thetransmitter.org. Relying on them, as Unz does, without skepticism, leads to one-sided arguments.

Accuracy Tally: Out of the major claims we examined, a few were accurate or mostly accurate (e.g., historical decline due to sanitation, COVID vaccine fear overestimates), several were partially accurate (e.g., trial design criticisms, VAERS limitations – factual points stretched to insinuations), and quite a few were inaccurate (MMR-autism cover-up, polio cause and vaccine impact being misrepresented). The net effect is an article that contains kernels of truth but arranges them in a misleading mosaic that could easily leave a reader doubting proven public health measures.

For editors and journalists, the takeaway is a caution: just because a source cites numbers or references doesn’t mean it has presented them in context or with balance. This article demonstrates how an ostensibly well-referenced piece can nonetheless mislead by selective emphasis and omission. A robust fact-check (like above) reveals that many sensational claims do not hold up against primary sources.

Journalistic Recommendation: In pieces on vaccine history or safety, it’s crucial to seek input from qualified experts or peer-reviewed syntheses. High standards of factual accuracy require that extraordinary claims (e.g., “polio was a pesticide issue”) be vetted against the consensus of subject-matter experts and decades of research – not just accepted because an activist book said so. Given the findings, an editor should consider issuing corrections or at least clarifications if such an article were to be published, especially for sections on polio and HIV that are highly misleading.

Upholding Factual Standards: Ultimately, while questioning orthodoxies is a legitimate journalistic endeavor, it must be done with intellectual honesty and rigorous fact-checking from authoritative sources. In “Vaccines and the Mystery of Polio,” that standard was not met. Our analysis underscores the importance of scrutinizing sources’ credibility and context to avoid disseminating claims that don’t withstand scrutiny.
