delighting anti-vaccine activists, drawing a rebuke from a key Republican senator and sparking an uproar among medical professionals and autism advocates who questioned whether the agency’s credibility is now gone. Before the Wednesday update, the CDC webpage stated that studies have shown that there is “no link” between vaccines and developing autism, and that “no links” have been found between any vaccine ingredients and the disorder, according to archived webpages. Robert F. Kennedy Jr. said he personally instructed the CDC to abandon its position that vaccines do not cause autism.

The American Academy of Pediatrics (AAP) provides an alternative source of information, as does the American Medical Association (AMA) and other medical organizations like Restored CDC or The Public Health Collaborative for health guidance. These groups are responding to recent changes on the CDC website regarding vaccine safety and offer evidence-based information through their own platforms.
