Risk Factors for Autism Spectrum Disorder: What We Already Know From Scientific Evidence

Secretary of Health and Human Services Robert F. Kennedy Jr., who as of late August 2025 says he is nearly ready to announce “causes” of a supposed “autism epidemic,” has a long history of fraudulent claims about autism spectrum disorder (ASD), including his repeatedly-disproven theory that vaccines cause it. Kennedy clearly decided long ago that vaccines in particular cause ASD, rejecting data that debunk this claim and energetically searching for anything that supports his preconceived notion – no matter how tenuous or far-fetched.
In order to clear the air and prepare the public to understand any falsehoods in Kennedy's announcement, DPH has put together a review of what research truly tells us about ASD, including why the whole notion of an "autism epidemic" is false.
