The CDC’s website now says a link between vaccines and autism cannot be ruled out.

That’s a sharp reversal from the CDC’s stance that there is no link. The change comes even though a connection between vaccines and autism has long been debunked by a large body of high-quality research. But Health Secretary Robert F. Kennedy Jr. has long promoted the discredited claim.

The move has alarmed public health experts already worried about a drop in childhood vaccination, which has led to a resurgence of dangerous childhood diseases like measles and whooping cough.
