CDC's rewritten autism page (first changed Nov 19-20, 2025): the headline 'Vaccines do not cause Autism*' is retained with an asterisk — a footnote says it was kept due to an agreement with the Senate HELP Committee chair — while the body invokes the Data Quality Act, compares the 1986 and 2025 infant schedules, criticizes the Danish MMR studies as retrospective epidemiology that cannot prove causation, discusses aluminum content, and announces that 'HHS has launched a comprehensive assessment of the causes of autism.'
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.

CDC's rewritten autism page (first changed Nov 19-20, 2025): the headline 'Vaccines do not cause Autism*' is retained with an asterisk — a footnote says it was kept due to an agreement with the Senate HELP Committee chair — while the body invokes the Data Quality Act, compares the 1986 and 2025 infant schedules, criticizes the Danish MMR studies as retrospective epidemiology that cannot prove causation, discusses aluminum content, and announces that 'HHS has launched a comprehensive assessment of the causes of autism.' This is the primary document for the 2025-2026 federal-shift claim; its content departs from CDC's prior position and is contested by AAP, the Autism Science Foundation, and Sen. Cassidy (MMD-16, MMD-17, MMD-18).
