“Vaccines do not cause autism” — true or false? According to investigative journalist Jeremy Hammond, “No studies have been designed to test the hypothesis that vaccines administered according to the CDC or AAP recommendations can contribute to the development of autism in susceptible subpopulations of children. Consequently, it is not logically possible for the hypothesis to have been falsified.” Watch his presentation, today, for a detailed breakdown of this statement. But first, Karl Jablonowski, Ph.D. joins the show to fact-check claims made by a well-known vaccine advocate. Viewers won’t want to miss it!
Well, I’ve investigated that body of literature over the course of many years.
The truth is that no studies have been designed to test the hypothesis that vaccines administered according to CDC or AAP recommendations can contribute to the development of autism in susceptible subpopulations of children.
Consequently, it is not logically possible for the hypothesis to have been falsified.
I titled the presentation “A Tale of Two Studies” because it highlights the following two studies:
Hviid et al. 2019 — a Danish study purporting to prove no assication between the MMR vaccine and autism even among genetically susceptible children
Andersson et al. 2025 — a Danish study purporting to prove no association between aluminum-containing vaccines and chronic illnesses, including allergic diseases, autoimmunity, and developmental disorders
I reveal how both studies were systematically biased in favor of the null hypothesis.
That is to say, they were designed to find no association.
Today, we are airing a special presentation by investigative journalist Jeremy Hammond, and the presentation is on aluminum adjuvants in vaccines. This is such an important presentation. Jeremy is a good friend of CHD, a good friend of mine, and you really need to watch this.
Watch it in the above episode ofDoctors & Scientists(starts at 20:11 in the video).

Three weeks after the McCullough Foundation released its Landmark Autism Report—a comprehensive 300-study analysis detailing decades of overlooked and suppressed evidence—the CDC has quietly reversed its 30-year public position on vaccines and autism.
In a stunning update to its own website, the agency now concedes that the long-repeated claim “vaccines do not cause autism” is not evidence-based, and further acknowledges that studies supporting a link have been ignored by health authorities. For the first time, a major U.S. public health institution is admitting that its categorical denials were not grounded in scientific certainty.
In this livestream, Epidemiologist Nicolas Hulscher, MPH, and Dr. Peter A. McCullough will break down exactly what the CDC changed, why the reversal happened now, and how the McCullough Foundation’s Landmark Autism Report forced global scrutiny of long-ignored data. Together, they will analyze the scientific evidence the CDC can no longer dismiss, the collapse of the “settled science” narrative, and the implications for families, medical ethics, public policy, and institutional accountability. This is a historic turning point, and the truth — backed by evidence — is finally breaking through.
I have met a fair share of people with identical experiences to the parents in this audience. I suspect that in the near future we will see the same for those with COVID-19 injuries, and like before, almost everyone will deny they exist.
Former CDC Director Tom Frieden made an unusual post on X.
His post included these two images:
We’ve seen these studies before. But now, from Frieden others have cited a small subset of studies—a tightly curated list of 14 papers—as definitive prof that vaccines do not cause autism.
First problem: They left out of bunch of studies, and failed to report that not all vaccines have been tested for association with autism, and failed to report that association analyses are not critical tests of causality in the first place.
(My “Magic” slide from Life University, GA where the audience first learned that not all vaccines had been tested and that some positive results DID exist that linked vaccines and autism – 2015)
Beneath Frieden’s canned but polished talking points and “official” (e.g., AAP) institutional endorsements of the list of 14 lies a brittle and contradictory foundation. A closer examination reveals that not one of these 14 studies was equipped to test falsify (i.e., test to the point of rejecting it if it was false) the causal hypothesis. Each either used the wrong design, wrong comparison groups, or wrong statistical assumptions. What follows is a forensic critique of all 14 studies as presented in two pro-vaccine infographics presented by Frieden.
In addition to these substantial voices below stating that vaccines cause autism, the Institute of Medicine claimed in 2004 that vaccines are a plausible cause of autism and anyone who understands study design will know that there has never been a properly designed study that has debunked this fact. Vaccines are the main environmental factor that ALL children have been exposed to for three decades, and any study that has examined the cause of autism and NOT included the vaccination schedule in the investigation, is flawed before the study was even started. When I asked health officials why they were not including vaccines in these studies, they looked me in the eye and said “it would be unethical to deny a child a vaccine!”. Yet apparently it is not unethical to add unlimited drugs called “vaccines” to an infants body without testing them for safety or efficacy. That parents, is the stupidity of the so called “evidence-based medicine” that your government is using and these officials know they have been lying to you for decades.
Introduction: Autism spectrum disorder (ASD) is now estimated to affect more than 1 in 31 children in the United States, with prevalence rising sharply over the past two decades and posing an increasing burden to families and public health systems. Most of the literature on ASD characterizes it as a complex neurodevelopmental condition shaped by multiple determinants, including genetic liability, immune dysregulation, perinatal stressors, and environmental toxicants. Since 1996, the possible role of childhood vaccination has also been discussed and debated. This review synthesizes the full range of evidence to clarify both vaccine-related and non-vaccine contributors to ASD risk.
Conclusion: The totality of evidence supports a multifactorial model of ASD in which genetic predisposition, neuroimmune biology, environmental toxicants, perinatal stressors, and iatrogenic exposures converge to produce the phenotype of a post-encephalitic state. Combination and early-timed routine childhood vaccination constitutes the most significant modifiable risk factor for ASD, supported by convergent mechanistic, clinical, and epidemiologic findings, and characterized by intensified use, the clustering of multiple doses during critical neurodevelopmental windows, and the lack of research on the cumulative safety of the full pediatric schedule. As ASD prevalence continues to rise at an unprecedented pace, clarifying the risks associated with cumulative vaccine dosing and timing remains an urgent public health priority.
For over a century, vaccination has been repeatedly linked to severe neurological injuries including brain damage — with many modern studies showing a 3 to 7 fold increase in common chronic illnesses
To dodge this massive liability, all research into vaccine injuries (and many other catastrophes like Agent Orange) was suppressed so that health authorities could claim there was “no evidence” of vaccine harm
Another scheme was to redefine the brain injury as “autism” rather than encephalitis (which the U.S. government was legally required to provide injury compensation for)
Previously, children with significant vaccine brain damage were referred to as “mentally retarded.” However, after a multi-decade campaign cancelled “retarded” they were instead diagnosed as autistic — a vague term which blurs severe and minor disability together, thereby effectively concealing the severe cases from the public’s awareness
This article will reveal the manipulative techniques and wordplay that have been used to conceal vaccine injuries from the public’s awareness, as now is the time when we can at last end this atrocity
n my first “Mapping” article I covered about 850 studies and showed the six that stand out as the best — Gallagher and Goodman (2008 & 2010), Mawson et al. (2017A & 2017B), Hooker and Miller (2021), and Mawson and Jacob (2025).
In this article, I’ve covered several thousand more sources including hundreds of studies and a wealth of alternative data sources that provide a comprehensive picture of the autism epidemic in the United States. Together these two articles provide the most comprehensive map of the autism epidemic ever created. Previously I’ve made the case that medical decisions should be made based on the totality of evidence — well, this is the totality of the autism evidence as it stands right now.
Anexplosive peer-reviewed studyreveals a chilling reality: the childhood vaccine schedule is directly tied to the majority of autism cases among Medicaid-enrolled children.
This isn’t speculation, it’s data. The findings show that routine vaccinations account for most autism diagnoses in the study group.
This is a devastating crime against our children.
No one has been punished for it, and don’t expect that to change anytime soon.
Scientists have found that in children with autism: • Inflammatory chemicals like IL-1β, IL-6, and IL-8 are elevated • Their brains are often enlarged—a sign of swelling • Their blood-brain barrier and gut barrier are leaky • And aluminum—a known neurotoxin—is often found at sky-high levels inside their brains. • One study even found aluminum levels in autistic brain tissue that were higher than almost any human brain tissue ever recorded.
“The science is settled” is a phrase invoked not to convey certainty but to halt inquiry. This rhetorical flourish has been used repeatedly in public health communications, particularly regarding the long-standing controversy over a potential link between vaccines and autism spectrum disorders (ASD). A recent example of this can be found in the March 19, 2025 article from Johns Hopkins Public Health, titled“Vaccines Don’t Cause Autism. Why Do Some People Think They Do?”
The purpose of this rebuttal is not to assert that vaccines do cause autism in all cases, but to make the case—based on published literature and verifiable findings—that the issue remains scientifically unresolved, and prematurely declaring it “settled” is a disservice to science, to public trust, and to families seeking answers, and that the Johns Hopkins article blissfully ignores peer-reviewed studies worth considering that show their conclusion is recklessly irresponsible.
Science is a process—a dynamic, self-correcting, and transparent one. It requires that inconvenient evidence be explored, not erased. It requires that questions be welcomed, not stigmatized. And it demands, above all, that institutions committed to public health also commit to intellectual honesty.
The vaccine-autism connection has not been disproven. It has been politically and institutionally suppressed.
For the sake of public trust, scientific integrity, and the countless families still seeking answers, it is time to open the conversation—not close it.
An honest AI Chatbot read thelatest Mawson study, and concluded that the CDC should warn parents that it’s more likely than not that vaccines cause autism.
Vaccinations required for school attendance have increased nearly threefold since the 1950s, now targeting 17 infectious diseases. However, the impact of the expanded schedule on children’s overall health remains uncertain. Preliminary studies comparing vaccinated and unvaccinated children have reported that the vaccinated are significantly more likely than the unvaccinated to be diagnosed with bacterial infections, allergies, and neurodevelopmental disorders (NDDs).
Vaccines and autism:
There is no science that shows vaccines cause Autism …except in these published studies which show vaccines cause Autism:
Dr Wakefield’s special interest was inflammatory bowel disease and this paper reported a case series of 12 children with developmental disorders whose mothers also described a constellation of bowel symptoms appearing shortly after their child’s vaccination.
Wakefield’s co-authors included specialist physicians in psychiatry, histopathology, radiology and gastroenterology. After carefully documenting their research findings in the paper, the investigators cautiously concluded: “We have identified a chronic enterocolitis in children that may be related to neuropsychiatric dysfunction. In most cases, onset of symptoms was after measles, mumps, and rubella immunisation. Further investigations are needed to examine this syndrome and it’s possible relation to this vaccine.”
Factcheck.org is, once again, fact-checked by Dr. Lyons-Weiler and their opinion-based claims are debunked. Problem #1 The first problem is that there ARE studies that have found links between vaccines and autism. Here’s a figure of the CDC schedule in 2015. Problem #2 The second problem is two-fold: the studies that are alleged to have reported no association suffered miserably from low statistical power, they tested the wrong hypothesis..
1. Contrary to popular belief, there is actually a great deal of compelling evidence linking vaccines to autism. For example, regressive autism always develops shortly after vaccination—but never before, something that cannot happen unless one causes the other. Likewise, there is a significant amount of evidence correlating vaccine uptake with autism rates.
2. There is presently no accepted explanation for what is causing the explosion of autism we are facing.
3. The explosion of autism is one of the costliest diseases facing our country, so decades of hand waiving that has insisted there’s no scientifically valid explanation for this explosion doesn’t cut it.
If we want to see if the MMR vaccine causes autism, the best and simplest way to do that is simply to plot every autism case relative to the closest MMR vaccination date of that child. The date is the date when the parent or expert observer first noticed telltale ASD behaviors (andnot when a clinical diagnosis is made which could be years later).
” We have identified a chronic enterocolitis in children that may be related to neuropsychiatric dysfunction. In most cases, onset of symptoms was after measles, mumps, and rubella immunisation. Further investigations are needed to examine this syndrome and its possible relation to this vaccine.”
