REALITY PROJECT #1: VACCINES & AUTISM
The Claim: Childhood immunizations are fueling an autism epidemic
On November 19, 2025, the CDC modified its webpage on vaccines and autism with an asterisk an a barrage of claims about possible causal links between childhood vaccinations and autism. RFK Jr and his supporters have made these arguments repeatedly. Let’s break down the elements of this assertion and consider the evidence
This entry evaluates long-standing claims linking childhood vaccines to autism, consolidating authoritative evidence, diagnostic trends, and methodological context into a single, continuously updated resource. A summary of the evidence will be provided here a more complete catalog with raw data, references, and a discussion forum is being built on the Science Collaborative website.
Summary conclusion:
There is no evidence that any childhood vaccine causes autism, and strong evidence that the MMR vaccine does not cause autism.
