Concerns Regarding Recent Revision to CDC’s Autism and Vaccine Information

The Pediatric Infectious Diseases Society expresses deep concern regarding the recent revision to the CDC’s Autism and Vaccines page, which now states that “the claim ’vaccines do not cause autism’ is not an evidence-based claim”. This change, presented without accompanying evidence, undermines confidence in the agency’s longstanding commitment to protecting the health of the American public. Reports that this revision occurred without the knowledge of career CDC staff raise additional questions about the process behind this decision.

Vaccines are amongst the most rigorously studied environmental exposures in relation to autism. Research over decades – conducted globally and across multiple independent institutions – has thoroughly examined vaccine schedules, timing, and immunologic responses, as well as the rates of autism in those with and without exposure to vaccines and their components. The consistent conclusion from this extensive body of evidence is clear: vaccines do not cause autism.

Revising official public health information in ways that are inconsistent with established scientific evidence causes confusion for parents and guardians trying to do the best thing for their children, ultimately putting children at risk for preventable infectious diseases by undermining vaccine confidence. They also erode the public’s trust in healthcare providers and evidence-based guidance regarding vaccine safety and efficacy, and encourage the redirection of precious autism research funding dollars towards questions which have already been thoroughly addressed, taking away from other areas of real need.

PIDS respectfully urges CDC to review and correct the altered language regarding vaccines and autism to ensure it accurately reflects the scientific consensus. We also request that appropriate oversight bodies evaluate the process that led to this change and make certain that future content updates fully engage the expertise of CDC scientific staff.
