Do Vaccines Cause Autism

I keep hearing that certain vaccines may cause Autism? Do you believe this? Is it true?

At one time, there was a debate that Thiomersal (a mercury-based additive used as a preserative) was linked to childhood autism. However, almost all doctors and scientists studing this issue, as well as all major health agencies (CDC, World Health Organization, etc.) have found no link between vaccines and autism. In fact, many are concerned that this misconception will result in children going unvaccinated and causing an rise in preventable diseases (like measles).

This study from the American Association of Pediatrics has more information: http://www.aap.org/profed/thimaut-may03.htm

So where did this rumor come from? For autism to be diagnosed, the symptoms have to startaround three years of age. If childhood vaccines are given frequently during this time, it is not unlikely that a significant number of people will notice an association between a vaccine panel and the first onset of the symptoms of autism simply by chance.

In 2001, Thiomersal was phased out of vaccines,yet autism rates continue to increase.
