Most of the "evidence" for autism caused by vaccines is statistical manipulation, anecdotes, and scare-mongering. There is perhaps a very remote chance of a correlation but its almost certainly a case of "When I changed the windshield wipers on my car the AC quit. You wiper-villains owe me a new AC!" When bad stuff happens, people desperately grasp for a simple cause they can understand.

Get vaccines. Not only is it the responsible thing to do for your own children, it is the socially responsible thing to do for everyone else's children as well.
