I read that whole post and the comments. As much as I sympathised with what happened to that womans child, I still don't believe you should make scientific claims if you aren't at least a consultant.
I also found that thread extremely offensive because all the males in my family have Autism. My Grandad, my Dad, me, my Son. I have aspergers and we think my son will have it too, although Aspergers won't be recognised until later. He has an official diagnosis of Autism right now.
If you think vaccination causes Autism then you're a fucking lunatic. Sorry.
