The idea that vaccines cause autism has been a persistent myth, but it’s one that science has thoroughly debunked. 

The concern first surfaced in 1998 when a now-retracted study suggested a link between the MMR (measles, mumps, and rubella) vaccine and autism. 

Since then, numerous large-scale studies involving hundreds of thousands of children have found no evidence connecting vaccines to autism.

Health authorities around the world — including the CDC, WHO, and the American Academy of Pediatrics — all agree: vaccines are safe and do not cause autism. 

Misinformation can be powerful, but facts matter. Vaccines protect children from serious, life-threatening diseases, and avoiding them can have dangerous consequences for both individuals and communities.

So, What Causes Autism?

Autism spectrum disorder (ASD) is a complex condition influenced by genetic and environmental factors — not vaccines. It typically appears in early childhood and affects behavior, communication, and social interaction. 

While the exact cause is still being researched, there’s a growing understanding that brain development differences play a key role.

Instead of focusing on outdated and disproven theories, families are better served by focusing on early diagnosis and effective support. One of the most trusted and effective treatments is Applied Behavior Analysis (ABA) therapy.
