FALSE

I'd love to help you understand the facts about this important topic! Scientific experts have concluded that vaccines do not cause autism 12. Decades of rigorous research, including extensive studies on the measles-mumps-rubella (MMR) vaccine, have found no link between vaccinations and the development of autism 210. While a change to the CDC's website in late 2025 began to suggest otherwise 45, medical organizations like the Autism Science Foundation and the American Academy of Pediatrics have characterized these updates as “baseless” and “not evidence-based” 678. Experts emphasize that the older studies often used to claim a link are “critically flawed” and have been thoroughly debunked by the global scientific community 911. Ultimately, vaccines remain one of the most well-studied and safest tools we have for protecting our health 110.
