Trump also urged not giving Tylenol to young children, but scientists say that research indicates autism develops in the fetal brain. The theory is that some, not all, children with autism may not properly metabolize folate, Mandell said. Decades of studies show no link between vaccines and autismDuring the press conference, Trump said he's a believer in vaccines but claimed without evidence that giving vaccinations close together at the recommended ages has a link to autism. Though anti-vaccine activists, including Kennedy, have long suggested a link between vaccines and autism, widespread scientific consensus and decades of studies have firmly concluded there isn't one.
