Key Facts
Kennedy, pointing to studies he claimed show “the countries that use the most [acetaminophen] have the highest level of autism,” said “it’s not proof. We’re doing the studies to make the proof.”
He also said there are “two studies that show children who are circumcised early have double the rate of autism, and it’s highly likely it’s because they’re given Tylenol,” to which Trump replied “there’s a tremendous amount of proof or evidence,” without giving examples.
Previous studies on a potential link between autism and acetaminophen have produced inconclusive results, and major medical groups have refuted the Trump administration’s recommendations that pregnant women shouldn’t take Tylenol, reiterating that it is safe to treat fever and pain and noting untreated fevers during pregnancy carry significant health risks.
