$50 Million NIH Autism Study Ignores Link to Vaccines, CHD Scientist Says

A $50 million federal research initiative examining the potential causes of autism is sidestepping any examination of a possible vaccine-autism link and is instead funding research by establishment scientists who have denied such a link, a new letter to National Institutes of Health (NIH) Director Jay Bhattacharya alleges.

The NIH announced the $50 million Autism Data Science Initiative (ADSI) last year. In his letter, Children’s Health Defense (CHD) Chief Scientific Officer Brian Hooker wrote that three projects funded by the initiative are led by scientists who “built their careers on explicit, public denial that vaccines could play any role in autism etiology.”

Hooker wrote that his review of the ADSI portfolio turned up no studies examining “vaccines or vaccine components.” The ADSI appears designed to come to a predetermined conclusion that vaccines are not linked to autism, Hooker alleged.

The NIH-funded research instead largely focuses on connecting autism to a range of genetic and environmental causes while ignoring a possible link to vaccines, Hooker said.

In an assessment accompanying his letter, Hooker called the ADSI, as currently structured, “not a search for the truth” but, instead, a “validation engine” for mainstream autism narratives.

Hooker told The Defender he was motivated to write the letter after the Aug. 19 ADSI update meeting and the Aug. 27 meeting of the federal Interagency Autism Coordinating Committee.

At the latter meeting, NIH Principal Deputy Director Matthew Memoli said the agency is “working toward more investigation of vaccines as a cause of autism,” according to Hooker’s original letter.

“Those are reassuring words. They are also, unfortunately, contradicted by the facts on the ground,” Hooker wrote. He told The Defender the ADSI instead “consists of a bunch of re-tread genetics projects that have been altered to look like gene-environmental interaction projects.”

Hooker’s allegations come despite recent reports that studying the vaccine-autism link is a priority for President Donald Trump and U.S. Health Secretary Robert F. Kennedy Jr.

Where Is the Outrage? Profound Autism Didn’t Used to Exist — Now It’s Everywhere

If I had walked into my fourth-grade classroom in 1978 and told my teacher that one day virtually every school district in America would have multiple classrooms dedicated to children who could not speak, who required one-on-one aides, who wandered, who self-injured, who had seizures, who would require lifelong care, she would have assumed I was describing some dystopian science fiction novel. Yet here we are. Why are we just accepting it?

Country artist Tyler Hudson came bombing through the U.S. last week (he’s a Texan living in Australia), and one of his Instagram posts about autism did something that really doesn’t happen to me anymore after 22 years as an autism dad: it choked me up.

His post was a read-aloud excerpt from his new book, “The Missing Lyrics,” that discussed a poem written by his NT (neurotypical) daughter about his teenage son with profound autism, whose name is Lyric.

I was fine until these words:

“He’s never been to a party, never walked into a friend’s house … if I could cure him I would. Acceptance looks really nice on a T-Shirt until he bites himself so hard he bleeds. If I could cure him I would … It’s love that makes us fight for a cure, a life.”

I want to personally thank Tyler Hudson and his family for reigniting something in me that’s faded with time and with my focus on optimizing my son’s life: outrage.

I’m 57 years old, which means I have one advantage in this conversation that many people don’t: I remember the world before profound autism became commonplace.

That’s not nostalgia talking. It’s memory.

I went to elementary school in the 1970s. I played Little League. I rode my bike around the neighborhood until the streetlights came on. I went to church, summer camp, birthday parties, county fairs, airports, shopping malls and movie theaters.

I sat in packed gymnasiums and crowded cafeterias. I stood in line for the Scrambler at the fair behind a hundred kids I’d never met. I was surrounded by children everywhere I went, constantly, for my entire childhood.

Looking back, I can remember many of them. The kid who always picked his nose. The kid who couldn’t stop talking. The class clown, the bully, the shy girl, the future valedictorian. I even remember the girl in my sister’s grade with Down syndrome, because there was exactly one.

What I cannot remember — not a single time, not once, not anywhere — is a child who couldn’t speak. A child who wore a helmet because he smashed his head into concrete.

A child who shrieked uncontrollably for hours. Parents wrestling a teenage son twice their size to keep him from hurting himself. A mother scanning a parking lot in a panic because her nine-year-old bolted and can’t say his own name.

I’ve asked hundreds of people my age the same question, and I get the same answer every time, usually after a long pause and a puzzled look. They don’t remember it either. (Ask a former nurse or teacher over the age of 70, and you’ll get the same response, too.) If those children existed in our world, they were so extraordinarily rare that none of us ever encountered them.

Today, they are everywhere. And the most astonishing part isn’t that our world changed. It’s that we’ve stopped acting like it did.

Think about that for a minute. If I had walked into my fourth-grade classroom in 1978 and told my teacher that one day virtually every school district in America would have multiple classrooms dedicated to children who could not speak, who required one-on-one aides, who wandered, who self-injured, who had seizures, who would almost certainly require lifelong care, she would have assumed I was describing some dystopian science fiction novel.

She would have asked what happened. She would have wanted to know what we did about it. Any reasonable adult in 1978 would have.

Yet here we are. We built an entire infrastructure around this new reality — special education departments, behavioral therapy franchises, sensory gyms, respite care agencies, Medicaid waivers, sibling support groups, adult residential services, a whole professional class of people whose careers exist because of it.

We did it fast, and we did it without ever really pausing to say out loud what the construction of that infrastructure implies. You do not build all of that for a population that has always been there. And somewhere along the way we collectively decided to stop asking the most obvious question in the world:

How the f*&^ did this happen?

Two CDC studies on vaccines and autism using the same data find opposite conclusions. Both cannot be correct

Two US Centres for Disease Control and Prevention (“CDC”) studies of the autism rate in Denmark in the 90s: the first one, produced by admitted felon Poul Thorsen, says the autism rate increased from 1995 to 2000, which was then used to claim there is no connection between giving infants mercury in vaccines and autism; the second study found that the autism rate in Denmark not only decreased from 1995 to 2000, but was more than 10 times higher than the rate claimed by Thorsen. At least one of these studies is bogus. 

Thorsen was a Danish researcher hired by the CDC in 1999 to do a series of studies, including several on the role of vaccines causing autism. He was indicted for embezzling more than $1 million from the CDC and other crimes by a US federal court in 2011.  He lived openly in Denmark, where he was an instructor at Aarhus University, but was finally arrested and extradited to the US in 2025. Yesterday he pleaded guilty.

The first study, ‘Thimerosal and the Occurrence of Autism: Negative Ecological Evidence from Danish Population-Based Data’, a widely publicised and highly influential study released in 2003, claimed that mercury in vaccines played no role in causing autism because the rate of autism in Danish children increased after mercury was removed from Danish-produced vaccines in 1992. 

Another CDC study, ‘Recurrence of Autism Spectrum Disorders in Full- and Half-Siblings and Trends Over Time: A Population-Based Cohort Study’, led by Therese K. Gronborg and released in 2013, however, shows the exact opposite: that the rate of autism in Danish children decreased after mercury was removed. And if the increasing rate of autism claimed in the earlier study showed that mercury had no role in causing autism, then logic would also require that the rate of autism going down, as shown in the current study, indicates that mercury in vaccines may very well have a great deal to do with causing autism.

Former CDC Scientist Whose Studies Were Used to ‘Debunk’ Vaccine-Autism Link Will Plead Guilty

A former Centers for Disease Control and Prevention (CDC) scientist who played a crucial role in research rebutting any link between vaccines and autism is expected to plead guilty next week to wire fraud and money laundering.

Poul Thorsen, 65, is finalizing a plea deal with prosecutors relating to charges stemming from a 2011 federal indictment, Nathan Kitchens, assistant U.S. Attorney for the Northern District of Georgia, told The Defender.

Thorsen, who began working for the CDC in the late 1990s, faces two counts of wire fraud and nine counts of money laundering related to over $1 million in CDC grant money. The funds were earmarked for autism and public health research, but Thorsen allegedly used them to buy a home, two cars and a motorcycle.

Kitchens declined to comment on whether Thorsen will plead guilty to all or some of the charges.

Thorsen has been held in federal custody without bail since his extradition from Germany to the U.S. in May. The case is being heard at a federal court in Georgia, where the CDC is headquartered.

Researcher James Grundvig, the parent of a child with autism who was vaccine-injured, called the expected guilty plea “a very big deal.”

Grundvig, who wrote “Master Manipulator: The Explosive True Story of Fraud, Embezzlement, and Government Betrayal at the CDC,” which focused on the Thorsen case, praised U.S. Health Secretary Robert F. Kennedy Jr. for extraditing Thorsen “in record speed.”

He said Thorsen likely understands that the FBI and U.S. Department of Justice have “all the goods” to prosecute him.

“I guess Thorsen’s realizing, since he’s in American jail already and has no chance for bail, he might as well make a plea deal,” Grundvig said.

Vaccine Cartel Desperately Clings to New MMR Vaccine–Autism “No Link” Study Riddled With Major Flaws

A new Pediatric Infectious Disease Journal study is being promoted by the pharma-captured mass media apparatus as a massive 2.56-million-child analysis disproving an MMR–autism association, but major methodological problems undermine the entire paper.

They did not use a truly unvaccinated control group, did not clinically adjudicate autism, did not interview parents, did not independently verify vaccine histories, and used a narrow ICD-coded autism definition.

No True Unvaccinated Control Group

Most importantly, there was no true unvaccinated control group. The comparison children were only those without a recorded MMR vaccination during the relevant analysis. They were not required to be vaccine-naive and could have received other routine childhood vaccines. The study itself reports that 62.1% of the overall cohort received a PCV booster.

Even their MMR status was not independently verified. Vaccination exposure came from Epic records, including historically documented doses, with no reported state immunization-registry confirmation, parent interview, or outside-record review. That means some children classified as “unvaccinated” in the dataset could theoretically have received MMR outside the participating Epic/Cosmos system without that dose being captured.

Autism Was Based on ICD Codes, Not Clinical Adjudication

The study relied entirely on electronic health records. Autism was defined by an ICD-10 F84.0 encounter code, not by independent clinical adjudication, ADOS testing, chart review, or parent interview. Nearly 9% of autism cases had only a single encounter carrying the diagnosis. Vaccine status was likewise taken from Epic records, with no reported state-registry verification, parent confirmation, or external record review.

The Study Did Not Measure the Full Autism Spectrum

The investigators counted only ICD-10 F84.0 “childhood autism,” a relatively narrow diagnostic code, rather than the broader range of autism-spectrum diagnoses captured under F84.Yet the 3.2% national benchmark they cite reflects that broader autism-spectrum definition. This means their 2.55% autism prevalence is not directly comparable to the national 3.2% figure and may miss children coded under other autism-spectrum categories. The authors themselves acknowledge this limitation and state that future studies should examine the full F84. spectrum.

Is a Federal Autism Committee Ignoring Vaccine-Autism Research?

draft strategic plan publicized by a federal autism committee last month outlines a framework for developing “precision” medical treatment and supporting better long-term care for autistic people — but, according to critics, makes no provision for studying a possible link between vaccines and autism.

The Interagency Autism Coordinating Committee (IACC), which advises U.S. Health Secretary Robert F. Kennedy Jr. on autism policies, released the draft plan for public comment last month. The plan recommends defining autism as a condition that may have more than one cause, and that may lead to multiple medical conditions.

The draft plan is also linked to ongoing federal research examining the possible causes of autism and the reasons for its increased prevalence in the U.S. — rising from 1 in 150 children in 2000 to 1 in 31 children in 2022.

According to a statement by the Autism Action Network reviewed by The Defender, while the role of vaccines in autism “is the most contentious and important of the many unanswered questions about autism,” the draft strategic plan includes no mention of studying a possible link.

“Nowhere in the current draft … are ‘vaccines’ or ‘immunizations’ even mentioned, nor are they identified as research subjects for causing autism,” the statement reads.

According to the statement, the report cites environmental factors and medical products as possible factors contributing to the onset of autism. But while these are “broad categories which could include vaccines,” the plan lacks “unequivocal, explicit language” calling for vaccine-autism research.

However, a person familiar with the workings of the IACC who asked to remain anonymous told The Defender that “nothing is excluded and nothing is off the table.”

The source said it was “very important” for the committee to avoid focusing on any one particular potential cause, and for “multiple members of the committee not to be reductionistic and not to reduce autism to one cause or one factor, because I think it’s very clear at this point that this is a sort of a multifactorial process.”

The individual said that the community of autistic people and their caretakers is “drowning” — and requires care and support instead of negative attention.

“Our community is drowning. We have parents, support givers and caregivers who are just inundated with behavioral and caregiving stress … it was very important to the many members of the committee that we make headway on those areas without encountering the massive onslaught of negative attention and coverage that would come from naming any particular environmental exposure.”

Data from a large autism clinic shows 40% of sudden regression autism happened within 2 days after vaccination

Even though this is a crisis, we do not really want to know the true cause of autism.

Why? Because if we used a time proximity analysis, it would reveal that the parental decision to follow their pediatrician’s advice and vaccinate their kids is the cause.

Congress will not investigate because they will lean on large studies which use methods designed specifically not to find a signal to claim vaccines don’t cause autism. But those studies only prove that bad studies can fail to find a signal if they use the wrong methods.

The most sensitive method is simply to make a histogram of the time between a child’s most recent vaccine and the onset of rapid regressive autism. The methodology was described in my earlier Substack article.

You can do this in any autism practice anywhere in the world retrospectively. It is simple. NOBODY HAS DONE THIS. I wonder why?

It took a long time, but I finally located a large autism treatment clinic who was willing to share the statistical information that they had gathered from the parents of autistic kids in the clinic that I wrote about in an earlier Substack article.

This is new. This has never been revealed to the world before. Nobody would dare do that.

The clinic examined 182 patient records.

84 were “rapid onset autism” cases (46%).

Of those cases, a “routine vaccination” was mentioned as happening before the event in 98% of those cases.

In 40% of the cases, the regression happened within 2 days after routine vaccination.

In 76% of the cases, the regression happened within 2 weeks after routine vaccination.

These numbers cannot happen by chance.

The only explanation is vaccines cause autism. Adding acetaminophen post-vaccine makes the autism outcome more likely.

However, if you believe otherwise, please explain in the comments what you think is causing these cases.

I predict there will be no follow ups on this from any country in the world because they don’t want to know the truth that they are causing the autism epidemic.

This data is stunning. I’m arranging funding of a larger version of this study and hopefully, we can get it on a preprint server. It will likely never be published in any mainstream journal.

‘Three-Way Collision’: How Genes, Mold and Vaccines Might Lead to Autism

Take a genetically susceptible child, expose that child to mold, and then add an immune trigger — like a vaccine — that “tips an already-strained system over the edge,” and you may create a “three-way collision” that can lead to autism, according to Dr. Christian Bogner.

Bogner, a physician and researcher, and other experts told The Defender that environmental triggers have become more prevalent in recent decades, with the expansion of the childhood immunization schedule and the widespread use of toxic pesticides, including glyphosate, to produce food.

Many blame toxic exposures for the drastic increase in autism diagnoses among U.S. children, which the Centers for Disease Control and Prevention measured at 1 in 31 children in 2022 — up from 1 in 10,000 in the 1970s.

Physician and author Dr. Neil Nathan believes there is “clearly a relationship” between one of those toxic exposures — mold toxicity — and autism, though studies attempting to identify a link have so far been few and inconclusive.

“It’s hard enough to get any studies done on toxic mold that get into the mainstream narrative — to say nothing of the vaccine issue,” said Dr. Margaret Christensen, a trained gynecologist, clinical educator and co-founder of the Carpathia Collaborative.

According to Christensen, exposure to toxic mold “affects everybody … as it is such a common environmental toxin.” She noted that at least half of homes and 60% of commercial buildings “have had sufficient water damage to have a toxic mold issue as a component to common environmental exposures, creating illnesses.”

Bogner said that each child has different levels of susceptibility when exposed to toxins. Even within the same household, two children exposed to the same toxins may have different outcomes — one may become very ill or develop autism while the other may remain healthy.

But there’s at least one common denominator among the sick children he’s treated: an imbalance in the gut.

“Triggers vary — some children were pushed by vaccines, some by mold, some by antibiotics, some by none of those — but every autistic child I have evaluated has dysbiosis,” Bogner said. These children “carry specific bacterial overgrowths” that lead to toxicity in the gut and the potential onset of neurological disorders.

What’s Behind Skyrocketing Autism Rates — Better Diagnostics? Or an Avalanche of Toxins?

A new study in JAMA Psychiatry suggests rising rates of autism and attention-deficit/hyperactivity disorder (ADHD) diagnoses are likely driven by broadening diagnostic criteria. But scientists at Children’s Health Defense said better diagnostics can’t on their own explain the steep increases in autism and ADHD rates since the 1990s.

Children’s Health Defense (CHD) scientists are pushing back against a study in JAMA Psychiatry suggesting that the global increase in autism and attention-deficit/hyperactivity disorder (ADHD) diagnoses is likely driven by broadening diagnostic criteria.

Brian Hooker, Ph.D., CHD chief scientific officer, and Karl Jablonowski, Ph.D., CHD senior research scientist, criticized the authors of the JAMA study for failing to consider that environmental toxins might be driving the increase.

Hooker said the authors overlooked the possibility that there are now so many toxic exposures that it takes very little genetic susceptibility to trigger autism or ADHD. Changes in diagnostic criteria may be a factor, Hooker said, but there is no way that it explains the steep increase in autism and ADHD rates since the 1990s.

Hooker told The Defender:

“What we’re seeing instead is a lowering of the genetic threshold required to reach a toxic tipping point as the toxic load between 1994 and 2016 skyrocketed with the expanding vaccination schedule, acetaminophen use, the GMO [genetically modified organism] revolution, etc.”

The authors of the JAMA study analyzed data from over 37,000 individuals in Denmark diagnosed with autism or ADHD over two decades. They reported that genetic risks for the conditions decreased over time, while diagnoses increased.

The study concluded that since genetic risk didn’t explain the increase in autism and ADHD diagnoses, the global surge in diagnoses was likely because the criteria used for diagnosing the conditions had broadened.

The authors claimed that the diagnosis threshold for autism and ADHD had lowered over time, so that kids who showed only mild symptoms were now being diagnosed.

The researchers examined three hypotheses for why diagnosis rates have increased — none of which took into account environmental toxins.

First, they thought it possible that diagnostic criteria for autism and ADHD may have broadened over time to include kids with milder symptoms.

Second, they thought maybe that psychiatric disorders that previously had been diagnosed as separate from autism or ADHD were getting lumped into autism or ADHD diagnoses.

Third, they speculated that there is now better detection of autism and ADHD than in the past.

Their data matched the first hypothesis but not the other two, they said.
