FALSE

Hello! I’m happy to help you look into this important topic. After reviewing the latest evidence, it's clear that the claim that vaccines cause autism is false 1 4. This idea originally gained traction from a 1998 study that has since been retracted and thoroughly debunked due to critical flaws and ethical concerns 6 7. Major health organizations, including the World Health Organization (WHO) and Johns Hopkins University, have reviewed vast amounts of scientific data and reaffirm there is no link between vaccinations and autism 2 9. While a 2025 revision to the CDC website suggests that a link hasn't been 100% ruled out 8, experts have clarified that this specific change is not evidence-based and contradicts decades of established science 5. Most experts agree that while autism symptoms often appear around the same time children receive routine shots, this is a coincidence of timing rather than a cause 3.
