No, autism is not caused by vaccines. This has been confirmed by extensive research over many years.
Large-scale studies from organizations like the Centers for Disease Control and Prevention (CDC) and the World Health Organization have found no link between vaccines and Autism Spectrum Disorder (ASD).
The concern originally came from a small study published in 1998, which has since been retracted due to serious flaws and misinformation. Since then, multiple high-quality studies involving hundreds of thousands of children have consistently shown that vaccines are safe.
So what causes autism?
Research points to a combination of:
- Genetic factors
- Early brain development differences
In our work with families, we often hear this concern, and we always emphasize that vaccines protect children from serious diseases without increasing autism risk.
