Autism: Resources & Information

Claims that vaccines cause autism have led some parents to delay or refuse vaccines for their children. The most common claims are that autism is caused by the MMR vaccine, vaccines that contain thimerosal, or too many vaccines. Many scientific studies have been done to test these claims. None has shown any correlation between vaccines and autism.

Vaccines Don't Cause Autism: Healthcare Triage #12

There is almost no topic in health and health policy that immediately polarizes people more than the idea that vaccines cause autism.

But there is a very, very large amount of research showing that vaccines and autism are unrelated.
