Trump made sweeping claims that would have ended political careers in any other era. His health officials tried to narrow the edges, but the President ensured that the headlines would be his.
Autism has long been the untouchable subject in American politics. For decades, federal agencies tiptoed around it, steering research toward genetics while carefully avoiding controversial environmental or pharmaceutical questions.
That ended at the White House this week, when President Donald Trump tore through the taboo with a blunt and sometimes incendiary performance that left even his own health chiefs scrambling to keep pace.
Flanked by Health Secretary Robert F. Kennedy, Jr., NIH Director Jay Bhattacharya, FDA Commissioner Marty Makary, CMS Adminstrator Dr Mehmet Oz, and other senior officials, Trump declared autism a “horrible, horrible crisis” and recounted its rise in startling terms.
“Just a few decades ago, one in 10,000 children had autism…now it’s one in 31, but in some areas, it’s much worse than that, if you can believe it, one in 31 and…for boys, it’s one in 12 in California,” Trump said.
The President insisted the trend was “artificially induced,” adding: “You don’t go from one in 20,000 to one in 10,000 and then you go to 12, you know, there’s something artificial. They’re taking something.”
Trump’s Blunt Tylenol Warning
The headline moment came when Trump zeroed in on acetaminophen, the common painkiller sold as Tylenol — known as paracetamol in Australia.
While Kennedy and Makary described a cautious process of label changes and physician advisories, Trump dispensed with nuance.
“Don’t take Tylenol,” Trump said flatly. “Don’t take it unless it’s absolutely necessary…fight like hell not to take it.”
Kennedy laid out the evidence base, citing “clinical and laboratory studies that suggest a potential association between acetaminophen used during pregnancy and adverse neurodevelopmental outcomes, including later diagnosis for ADHD and autism.”
Makary reinforced the point with references to the Boston Birth Cohort, the Nurses’ Health Study, and a recent Harvard review, before adding: “To quote the dean of the Harvard School of Public Health, there is a causal relationship between prenatal acetaminophen use and neurodevelopmental disorders of ADHD and autism spectrum disorder. We cannot wait any longer.”
But where the officials spoke of “lowest effective dose” and “shortest possible duration,” Trump thundered over the top: “I just want to say it like it is, don’t take Tylenol. Don’t take it if you just can’t. I mean, it says, fight like hell not to take it.”
Vaccines Back on Center Stage
The President then pivoted to vaccines, reviving arguments that the medical establishment has long sought to bury. He blasted the practice of giving infants multiple injections at a single visit.
“They pump so much stuff into those beautiful little babies, it’s a disgrace…you get a vat of 80 different vaccines, I guess, 80 different blends, and they pump it in,” Trump said.
His solution was simple: “Go to the doctor four times instead of once, or five times instead of once…it can only help.”
On the measles, mumps, and rubella shot, Trump insisted: “The MMR, I think should be taken separately…when you mix them, there could be a problem. So there’s no downside in taking them separately.”
The moment was astonishing — echoing arguments that had once seen doctors like Andrew Wakefield excommunicated from medical circles.
It was the kind of line of questioning the establishment had spent decades trying to banish from mainstream debate.
Hep B Vaccine under Attack
Trump dismissed the rationale for giving the hepatitis B vaccine at birth.
“Hepatitis B is sexually transmitted. There’s no reason to give a baby that’s just born hepatitis B [vaccine]. So I would say, wait till the baby is 12 years old,” he said.
He made clear that he was “not a doctor,” stressing that he was simply offering his personal opinion. But the move could also be interpreted as Trump choosing to take the heat himself, to shield Kennedy’s HHS from what was sure to be an onslaught of criticism.
The timing was remarkable.
Only last week, the CDC’s Advisory Committee on Immunisation Practices (ACIP) had been preparing to vote on whether to delay the hepatitis B shot until “one month” of age — a modest proposal that mainstream outlets derided as “anti-vax extremism.”
By contrast, Trump told the nation to push the jab back 12 years. His sweeping denunciations made the supposedly radical ACIP vote look almost tame.
The irony was inescapable — the same media voices who had painted Kennedy’s reshaped ACIP as reckless now faced a President willing to say far more than the panel itself dared.
A New Treatment and Big Research Push
The administration also unveiled what it deemed a breakthrough: FDA recognition of prescription leucovorin, a folate-based therapy, as a treatment for some autistic children.
Makary explained: “It may also be due to an autoimmune reaction to a folate receptor on the brain not allowing that important vitamin to get into the brain cells…one study found that with kids with autism and chronic folate deficiency, two-thirds of kids with autism symptoms had improvement and some marked improvement.”
Dr Oz confirmed Medicaid and CHIP (the Children’s Health Insurance Program, which provides low-cost health coverage to children in families that earn too much to qualify for Medicaid) would cover the treatment.
“Over half of American children are covered by Medicaid and CHIP…upon this label change…state Medicaid programs will cover prescription leucovorin around the country, it’s yours,” said Oz.
Bhattacharya announced $50 million in new NIH grants under the “Autism Data Science Initiative.”
He explained that 13 projects would be funded using “exposomics” — the study of how environmental exposures like diet, chemicals, and infections interact with our biology — alongside advanced causal inference methods.
“For too long, it’s been taboo to ask some questions for fear the scientific work might reveal a politically incorrect answer,” Bhattacharya said. “Because of this restricted focus in scientific investigations, the answers for families have been similarly restricted.”
Mothers’ Voices
The press conference also featured raw testimony from parents.
Amanda, mother of a profoundly autistic five-year-old, told Trump: “Unless you’ve lived with profound autism, you have no idea…it’s a very hopeless feeling. It’s very isolating. Being a parent with a profound autistic child, even just taking them over to your friend’s house is something we just don’t do.”
Jackie, mother of 11-year-old Eddie, said: “I’ve been praying for this day for nine years, and I’m so thankful to God for bringing the administration into our lives…I never thought we would have an administration that was courageous enough to look into things that no prior administration had.”
Their stories underscored what Kennedy said at the announcement about “believing women.” Here were mothers speaking directly about their lived reality, demanding that uncomfortable conversations could no longer be avoided.
Clashes with the Press Corps
Reporters pressed Trump on the backlash from medical groups.
Asked about the American College of Obstetricians and Gynecologists (ACOG) declaring acetaminophen safe in pregnancy, Trump shot back, “That’s the establishment. They’re funded by lots of different groups. And you know what? Maybe they’re right. I don’t think they are, because I don’t think the facts bear it out at all.”
When one journalist raised the argument that rising diagnoses reflected better recognition, Kennedy bristled,
“That’s one of the canards that has been promoted by the industry for many years,” he said. “It’s just common sense, because you’re only seeing this in people who are under 50 years of age. If it were better recognition or diagnosis, you’d see it in the seventy-year-old men. I’ve never seen this happening in people my age.”
Another reporter then asked Trump, “Should the establishment media show at least some openness to trying to figure out what the causes are?”
“I wish they would. Yeah, why are they so close-minded?” Trump replied. “It’s not only the media, in all fairness, it’s some people, when you talk about vaccines, it’s crazy…I don’t care about being attacked.”
Breaking the Spell
For years, autism policy has been shaped by caution, consensus, and deference to orthodox positions. That spell was broken at today’s press conference.
The dynamic was striking. Kennedy, Makary, Bhattacharya, and Oz leaned on scientific papers, review processes, and cautious advisories. Trump, by contrast, brushed it all aside, hammering his message home through repetition and personal anecdotes.
Trump made sweeping claims that would have ended political careers in any other era. His health officials tried to narrow the edges, but the President ensured that the headlines would be his.
“This will be as important as any single thing I’ve done,” Trump declared. “We’re going to save a lot of children from a tough life, really tough life. We’re going to save a lot of parents from a tough life.”
Whatever the science ultimately shows, the politics of autism in America will never be the same.
