The Trump administration is urging public health agencies to prioritize investigations of vaccine injuries, prescription drug use and autism's causes.

The Centers for Disease Control and Prevention plans to contract with Rensselaer Polytechnic Institute to investigate the debunked idea that vaccines cause autism, according to a notice on the federal website.

A much-investigated question about autism, dismissed in many studies, is getting a surge of new federal research money.

Health Secretary Robert F. Kennedy Jr. has promised to reveal what he calls the true cause of autism, a complex developmental disorder.

A special court's Thursday ruling that no proven link exists between autism and certain early childhood vaccines seems to have done little to change the sometimes-passionate opinion fueling the debate.

The video, which appears to be old, features Dr. Mark Geier and his son David, who together published numerous studies purporting to show the connection.

Notably, Gottlieb said during the interview that he believes HHS Secretary Robert F. Kennedy Jr. could use a forthcoming agency report to claim an association between alum -- an aluminum-based adjuvant used in some vaccines -- and autism, and that this claim could ultimately " take down the whole pediatric vaccine enterprise ."

Trump’s post comes just days after Kennedy was grilled by senators, including multiple Republicans, on his stance on vaccines.
