CDC Updates Vaccine-Autism Guidance to Reflect Gold Standard Science

by | Nov 20, 2025

A Centers for Disease Control and Prevention webpage that previously stated outright that vaccines do not cause autism has been revised, stating that health authorities may have ignored potential links between vaccines and the condition.


The updated page now reads, “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.” The revision was posted Wednesday.

The page also notes that the Department of Health and Human Services has launched “a comprehensive assessment” to investigate the causes of autism, though details on the assessment’s scope or methods are not provided. HHS spokesman Andrew Nixon said the update was intended “to reflect gold standard, evidence-based science.”
