Confirmed: ChatGPT, if it uses the CDC as a web source, now spouts vaccine misinfo.
![ChatGPT prompt: according to the cdc, do vaccines cause autism?
Response: Short answer: as of the CDC’s own webpage update on **November 19, 2025**, the agency says the plain claim **“vaccines do not cause autism” is not an evidence-based claim** because studies have not *completely* ruled out the possibility that infant vaccines could contribute to autism — and HHS has launched a review to look more closely. ([CDC][1])
Important context (why this looks confusing):
* For decades the CDC — and many large, well-conducted studies and reviews — have reported **no causal link** between routine childhood vaccines (including MMR) or vaccine ingredients like thimerosal and autism. Examples: CDC summaries, VSD studies and large population studies (e.g., Denmark) have found no increased autism risk. ([CDC Stacks][2])
* The November 19, 2025 CDC webpage represents a change in wording: rather than saying “vaccines do not cause autism” as an unequivocal statement, the CDC now says that that absolute claim is not fully evidence-based and that further assessment is underway. ([CDC][1])
What this means practically: the scientific literature to date contains many rigorous studies finding no causal relationship, but the CDC’s updated wording acknowledges that science is ongoing and that HHS is doing a fresh assessment. If you want, I can summarize the major large studies and reviews that found no link (or give the exact CDC wording and date).
