The CDC has made significant changes to its official website regarding the link between vaccines and autism, now suggesting that vaccines may cause autism, a reversal from its longstanding position that vaccines do not cause autism. This revision has been widely criticized as promoting debunked claims and reflecting the anti-vaccine views associated with Robert F. Kennedy Jr. The agency’s new language has sparked outrage among scientists and public health advocates who argue that it distorts established scientific evidence and undermines vaccine safety. The changes have created turmoil within the CDC, raising concerns over political influence on public health messaging.
