The Centers for Disease Control and Prevention (CDC) recently updated its online information on vaccines and autism. In earlier versions, the agency’s page explicitly dismissed any association between immunizations and autism spectrum disorders.
The latest revision no longer features the definitive statement that vaccines cannot be linked to autism. Instead, the page now acknowledges that some experts continue to question the strength of the existing evidence and that ongoing research is needed to address lingering concerns.
Health activist Robert F. Kennedy Jr., who has long advocated for a re‑examination of vaccine safety, welcomed the amendment. He said the CDC’s new wording “reflects the doubts many parents and scientists have raised about the original conclusion.”
While the CDC has not altered its overall stance that vaccines are safe and effective, the softened language may influence public perception and could prompt further scientific inquiry into the complex relationship between immunizations and neurodevelopmental outcomes.
