WASHINGTON (AP) 鈥� The nation’s top health agency will undertake a 鈥渕assive testing and research effort鈥� to determine the cause of autism, Health and Human Services Secretary Robert F. Kennedy Jr. announced Thursday.

Kennedy, a longtime vaccine critic who has pushed a discredited theory that routine childhood shots cause the developmental disability, said the effort will be completed by September and involve hundreds of scientists. He shared the plans with President Donald Trump during a televised Cabinet meeting.

Trump suggested that vaccines could be to blame for autism rates, although decades of research have concluded there is no link between the two.

鈥淭here’s got to be something artificial out there that’s doing this,鈥� Trump told Kennedy. 鈥淚f you can come up with that answer, where you stop taking something, eating something, or maybe it’s a shot. But something’s causing it.”

Autism is a developmental disability caused by differences in the brain. It presents with a wide range of symptoms that can include delays in language, learning, and social or emotional skills.

There鈥檚 scientific consensus that childhood vaccines don鈥檛 cause autism. Leading autism advocacy groups, including , agree.

Research, including studies of twins, shows genes play a large role. No single environmental factor has been deemed a culprit. The National Institutes of Health, which already spends more than $300 million yearly researching autism, lists some possible risk factors such as prenatal exposure to pesticides or air pollution, extreme prematurity or low birth weight, certain maternal health problems or parents conceiving at an older age.

Trump and Kennedy have both expressed concerns about rising autism diagnoses rates.

Some of that increase is due to increased awareness and a change in how the disability is diagnosed. For decades, the diagnosis was given only to kids with severe problems communicating or socializing and those with unusual, repetitive behaviors. But around 30 years ago, the term became shorthand for a group of milder, related conditions known as 鈥砤utism spectrum disorders.鈥� Milder autism cases are far more common than severe ones.

With improved screening and autism services, diagnosis is increasingly happening at younger ages, too. And there鈥檚 been more awareness and advocacy for Black and Hispanic families, leading to an increase in autism diagnosed among those groups.

Still, anti-vaccine advocates, including Kennedy, have claimed that vaccines are to blame. The theory largely stems from a 1998 paper that was later retracted.

Scientists have since ruled out a link between vaccines and autism, finding no evidence of increased rates of autism among those who are vaccinated compared to those who are not.

Kennedy has hired David Geier, a man who has repeatedly claimed a link between vaccines and autism, to lead the autism research effort. The hiring of Geier, who the state of Maryland found was practicing medicine on a child without a doctor’s license, was .

HHS did not immediately response to a request for comment.
