I would recommend that unless you are a health professional yourself, leave the issue and don't spread things which you have learnt over internet or email. There is a lot that you cant understand / or cannot be explained on a public forums.

1. FDA has very strict guidelines for approval of medicine and vaccination. They will not approve anything which causes more harm than good.

2. before recommending any intervention (not just vaccination) a lot is considered including side effects, long term benefits, statistical benefits and many other things.
( You have to be a public health expert to understand that ).

Bottom line is that you see chicken pox, polio, whooping cough in African and Asian countries and not in western ( at no where near the same prevalence).

I agree that you also see more autistic children but it is more down to better ways of recognizing the symptoms and special program aimed at them. There are far more number of "insane" children neglected in the streets in Asian countries who no one has tried to count.
