I love the enthusiasm, Raw-Al, and thanks for the stuff from Dr. Campbell-McBride, but I suspect that diet is a much larger factor in autism than vaccines. In my own experience, dietary change cleared up my brain fog, despite a typical history of vaccination. Don't worry, I don't discount completely the potential influence of modern vaccinations and other modern factors, but I think vaccination greatly misdirects people from the primary cause of autism--modern diet.
People like Jenny McCarthy and others change their childrens' diets with great success, but seem to assume nonetheless that vaccination is the primary cause. How odd it is that even in a dietary forum like this one that vaccination seems to still be pointed to primarily, over diet.
I suspect that one factor is that it's much easier to just avoid vaccinations than to dramatically change one's diet, into which are tied so many cultural influences.
