The agency cites the Data Quality Act, a 2001 information integrity statute, as its authority. Critics say the change contradicts decades of large scale studies and arrived just before a key Senate vote on the CDC director nominee.
Eight days before the Senate Health Committee votes on President Trump's nominee to lead the Centers for Disease Control and Prevention, the agency replaced the long-standing line "vaccines do not cause autism" on its public autism page with the claim that the original statement is "not evidence-based." The new text, dated July 22, 2026, cites the Data Quality Act — a 2001 federal information-integrity statute that lets the public challenge the accuracy of information disseminated by federal agencies — as the legal authority for the change.
The swap landed in the middle of a confirmation fight the White House needs Sen. Bill Cassidy (R-LA) to win. Cassidy chairs the Senate Health, Education, Labor and Pensions (HELP) Committee and had publicly demanded scientific-integrity assurances before he would back the administration's pick to run the CDC. The Independent reports the page is part of an "olive branch" intended to secure his vote. The committee vote is rescheduled for July 30.
The change is being reported as the public tail of a directive Health and Human Services Secretary Robert F. Kennedy Jr. first issued in 2025. In announcing the revision, the CDC said the prior statement had been "historically disseminated by the CDC and other federal health agencies within HHS to prevent vaccine hesitancy." HHS has launched a "comprehensive assessment" of autism causes that the page says will supply "gold-standard science" to replace the old language.
The legal wrapper is procedural. The Data Quality Act gives the public a procedural right to challenge the accuracy of information disseminated by federal agencies. CDC has not pointed to any outside scientific review that supports the new framing. FactCheck.org and KFF Health News have both, in coverage of an earlier CDC revision, characterized the revised framing as not evidence-based. The current revision is more recent than those characterizations.
The page also retains material that does not hold up. It still cites a 2010 hepatitis B vaccine and autism study by Cannon and colleagues, retracted in May 2026 after an independent statistical reviewer found "fundamental methodological flaws" and an "overstated conclusion." The page also says "approximately one in two surveyed parents" of autistic children believe vaccines played a role, citing a 2006 study, and points to a temporal correlation between rising autism prevalence since the 1980s and the rising number of infant vaccines, while itself noting that "correlation does not prove causation."
Reviews by the Institute of Medicine and the Agency for Healthcare Research and Quality, cited on the CDC's own page, concluded that the evidence does not support a causal connection between infant vaccines and autism. The page restates that finding as a procedural hedge — that there are "no studies that support the specific claim" — and uses the language to leave the larger question open in framing. The CDC's prior framing, preserved in a November 19, 2025 Wayback Machine capture, stated the conclusion directly. The current page does not.
Cassidy controls the HELP Committee vote on the CDC director nominee. Sean Kaufman, Trump's nominee to lead the Administration for Strategic Preparedness and Response — the HHS division that manages emergency medical countermeasure stockpiles — faces a separate hearing because of his past anti-vaccine statements. If the nominee is confirmed, the CDC director who inherits the new page will be the incoming agency head. If she is not, the page's authority to speak for the agency becomes the next fight.
For parents and clinicians with questions, the American Academy of Pediatrics continues to recommend the routine childhood vaccine schedule, and pediatricians can walk through family-specific data the new page does not. Watch the HELP Committee vote on July 30, the HHS assessment timeline, and any further edits to the autism page itself.
