Ann Bauer, a researcher who studies Tylenol and autism, felt queasy with anxiety in the weeks leading up to the White House’s much-anticipated autism announcement. In August, Bauer and her colleagues published an analysis of 46 previous studies on Tylenol, autism, and attention-deficit/hyperactivity disorder. Further, research has not deeply examined Tylenol risks in young children, and many rigorous studies refute a link between vaccines and autism. In addition, both Trump and Kennedy have repeated the scientifically debunked notion that childhood vaccines may cause autism. Helen Tager-Flusberg, director of the Center for Autism Research Excellence at Boston University, called Trump’s comments dangerous.
