If vaccines cause autism, then there should be less autism among those religious groups that refuse vaccinations, yet I've never read a study that shows that. Likewise 3rd world countries.

I believe this is true. There has been much info about the fact that the Amish have almost NO autism.

if it's thimerosal, then things should start to improve because they stopped using it

This is also beginning to happen.

"Amish have almost NO autism."

Yet their rate of SIDS is very high. There may well be a genetic filter at work.
