I saw a great doco on vaccines in SBS where a doctor discusses how vaccines seemed to speed up the symptoms of another disease and her conjecture was that vaccines do a similar thing for autism. They might not cause it, but they seem to provoke it if there is an underlying condition. It makes sense to me.

I think the idea of gut health and psychology is also well documented and I do think vaccines can put pressure on the body which is fine in most people but can bring about other problems.

So I think there is something linking vaccines and autism I don't think we will fully understand it for many years.
