This is a problem for scientific communication. A total lack of causation can never be proven for anything. You cannot prove that playing cello in your underwear doesn't cause autism. These charlatans exploit that.
@elizabethjacobs.bsky.socialThis is completely disgusting. Today, the CDC updated their vaccine safety page. It now says:
“The claim "vaccines do not cause autism" is not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism”.
