Is Autism Caused by Vaccines?

October 21, 2025

The short answer is no vaccines do not cause autism. This claim has been widely debunked by decades of scientific research. Major health organizations, including the CDC and WHO, confirm there is no link between childhood vaccines and autism spectrum disorder (ASD).


The myth began with a flawed study in the late 1990s that was later retracted due to serious errors and ethical violations. Since then, numerous large-scale studies have found no connection between vaccines like the MMR (measles, mumps, rubella) shot and autism.

Autism is a neurodevelopmental condition influenced by genetics and early brain development. It’s not caused by external factors like vaccines. Spreading misinformation can delay diagnosis and prevent children from receiving timely support.
