FACT CHECK #ET8LQJWM

WHAT WE FOUND

Extensive scientific research and high-credibility medical organizations confirm that vaccines do not cause autism 1 5 8 11. While a 2026 update to CDC guidance removed the categorical statement that vaccines do not cause autism based on data quality requirements 3, the National Medical Association emphasizes that no credible scientific evidence exists to demonstrate a causal link 4. Peer-reviewed studies involving over 1.2 million children found no association between the MMR vaccine and autism 10. Experts from Johns Hopkins and the American Academy of Pediatrics note that the original research suggesting a link was based on a flawed, small-scale study with no control group 6 and that autism is primarily driven by genetic factors rather than immunizations 1 7. The research is considered clear and consistent across more than a dozen major studies 12.
