FACT CHECK #EVW2BYUI

WHAT WE FOUND

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 This idea originally gained traction from a 1998 study that has since been retracted and thoroughly debunked due to critical flaws and ethical concerns 6 7.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.
