CDC in turmoil after agency backpedals on debunking vaccines-autism link; The Washington Post, November 20, 2025

Lena H. Sun,  The Washington Post ; CDC in turmoil after agency backpedals on debunking vaccines-autism link

"The Centers for Disease Control and Prevention has repudiated its past insistence that vaccines do not cause autism after decades of fighting misinformation linking the two, blindsiding career staff and delighting anti-vaccine activists.

The agency’s website on vaccines and autism, updated Wednesday, now makes several false claims about a connection, echoing longtime rhetoric from Health Secretary Robert F. Kennedy Jr., who has a lengthy history of disparaging vaccines and linking them to autism.

Career scientists at the agency responsible for information about vaccine safety and autism had no prior knowledge about the changes to the website and were not consulted, according to five agency officials, who spoke on the condition of anonymity for fear of retaliation."

"The Centers for Disease Control and Prevention has updated its website to promote the widely debunked claim that vaccines may cause autism. 

Why it matters: Health Secretary Robert F. Kennedy Jr. has repeatedly linked vaccines to autism, and now the public health agency he oversees is publicly reversing its position to reflect that belief. 

Multiple studies over decades have disproven links between childhood vaccines and developing autism. 

State of play: The agency's webpage on vaccines and autism, updated Wednesday, now says the statement that vaccines don't cause autism "is not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism."

"Studies supporting a link have been ignored by health authorities," the website continues. 

HHS in September released plans to contract with Rensselaer Polytechnic Institute to research connections between vaccines and autism. 

Career scientists at the agency were not consulted about the changes and were caught off guard by them, the Washington Post reported.

The CDC site previously said studies showed there was no connection between receiving vaccines and developing autism."
