U.S. President Donald Trump on Monday exposed autism to the use of a child’s vaccine and the popular painkillers for women when they are pregnant and raised claims that are not supported by scientific evidence, which is the forefront of U.S. health policy.
During an extraordinary press conference at the White House, the Republican president provided medical advice to parents of pregnant women and young children, repeatedly not using or managing Ponciller’s ratings, and taking non-acceptance of common vaccines.
Trump’s advice, who said he is not a doctor, opposes the advice of the medical society, has shown that numerous studies have shown that acetaminophen, the active ingredient in Tylenol, plays a safe role in the well-being of pregnant women.
“What I want to say is, don’t take Tylenol. Don’t accept it,” Trump said.
“Other things we recommend, or what I would do anyway… don’t let them attract your kids with a bunch of the biggest things in your life,” he said, referring to the vaccine.
Trump administration supports leucovorin as treatment
Trump’s team recommends leukolic acid (a form of folic acid) as a treatment for symptoms of autism.
Dozens of medical, research and autism advocacy groups, including the American Academy of Pediatrics and the American Academy of Obstetricians and Gynecology, condemned the president’s announcement.
“The data cited does not support the claim that Tylenol causes autism, and white blood cells are a cure, with only Stoke and false tips proposing hope when there is no simple answer,” the alliance of autism scientists said in a statement.

“Independent, sound science clearly shows that taking acetaminophen does not cause autism. We strongly disagree with any advice and pay deep attention to the health risks of expectant mothers and parents,” said Kenvue, a manufacturer of Tylenol.
Kenvue stock recovers in late-night trading
Shares of consumer health company Kenvue recouped 5% in expansion trading after falling more than 7% in Monday’s trading session.
Since September 5 Wall Street Journal Kennedy plans to link acetaminophen to autism, the report said. Kenvue broke away from Johnson and Johnson in 2023.
Trump says he is a loyal believer in the vaccine, his first pandemic initiative Accelerate the development of Covid-19 vaccines. Nevertheless, he called for the removal of mercury from the vaccine and said children should not receive the hepatitis C vaccine before the age of 12. Usually given within the first 24 hours of birth. He also said that the measles pancake rubella combination vaccine should be divided into three separate lenses.
The Tylenol-autism link announcement is reminiscent of Trump’s regular press conferences in the early days of the pandemic, when he often assigned science-based advice, including those he ingested later, his advice was his supporters.
Research shows that vaccines are safe and can eliminate childhood diseases such as polio and measles. Michael J. Nyenhuis, U.S. president and CEO of UNICEF, said that over the past 50 years, it is estimated that basic vaccines have saved at least 154 million lives.
Only one in four Americans believe that the Trump administration’s latest recommendations for the Feer vaccine are based on scientific evidence and facts, Reuters/ipsos Polls show this month.
“I can’t say I’ve ever experienced anything in the vaccine,” said Dr. Norman Baylor, former director of the FDA’s Office of Vaccine Research and Review.
Trump administration announces steps
Food and Drug Administration head Marty Makary told reporters that the Trump administration has asked pharmaceutical companies to prepare for the disaster to make up for treatment for some people with autism.
The FDA approved a version of the drug made by GSK to treat autism-related diseases, but drugmakers no longer produce it. The government said Medicaid coverage for low-income people will cover medications with symptoms of autism once use is established.
During its approval process, the FDA cited a review of the use of leukocyte protein in 40 patients with rare metabolic diseases, called cerebral folate deficiency, which may lead to a range of neurological symptoms, some of which have been found in patients with autism.
The FDA said this would make label changes for over-the-counter Tylenol and its universal version to reflect evidence that use during pregnancy may be associated with an increased risk of neurological conditions such as autism and ADHD in children. The FDA also sent a letter to the doctor and said that no causal relationship has been established.
Researchers say there is no causal relationship
There is no solid evidence for a link between Tylenol use and autism, the researchers say. A 2024 study of nearly 2.5 million children in Sweden found no causal relationship in uterus with acetaminophen and neurodegenerative disease.
Reviews of 46 early studies in 2025 did show a link between exposure to prenatal acetaminophen and an increased risk of these diseases, but researchers at the Icahn School of Medicine at the Islamic Mountains of Harvard, Harvard University, etc. said the study did not provide the drug.
They recommend that pregnant women continue to use acetaminophen as needed in the lowest box and the shortest period. Trump officials cited the review and used similar language to recommend how much Tylenol should be taken.
“It’s obvious that the Tylenol-Autism link is not a new problem – in many different studies, it has been studied.”
“No evidence was shown to support them, so the announcements became reckless and potentially harmful.” The researchers said that leucovorin used to treat some cancer patients in chemotherapy showed some hope in very small trials, but large randomized trials are still needed.
“There is no sufficient evidence to show that it works. There are some studies, but they are small and not the best ones. So, that’s certainly not something I actively recommend.”
