I kind of like Matt, at the end.

The subject is controversial. It isn't just autism, but the rest of the new "childhood" illnesses previously unheard of in children (diabetes, MS, RA, etc.)
The scientists themselves admit that they don't know much about the immune system of human beings. No one in their right mind would agree that shooting up kids with dozens of viruses, preservatives and all the other crap can do nothing to a healthy human being. When I was a baby, my first year I had 2 shots (TD). That's it, not 25 viruses.
I've been saying this for a while: "When I see doctors', pharm reps, pharm owners, CDC, FDA people vaccinate their kids on TV with all the vaccines that they want to shoot up my baby with, then I might reconsider."
Anyway, I think Offit and pharma's point is moot - they have no legal/financial responsibility for what they say and do everyday and see to profit from it -- so they are no experts to me.
