One of the reasons that pro-vaccine supporters argue that Autism is not caused by vaccines is that there are cases of Autism in children who were not vaccinated. I'm wondering: Has anyone ever asked the parents of these children if and when the mother had been vaccinated? We know that so many things are passed on from the mother to her child via the womb. Example: I have heard that dietary choices made by the great grandmother while pregnant can affect the health of offspring 2-3 generations out. Has anyone ever suggested the possibility that the Autism was passed on to the child from the mother's vaccinations?
