Reply #2: There is a strong implication that the autism epidemic is largely environmentally caused. [View All]

Either people are genetically predisposed to vulnerability to this environmental trigger, or the environmental triggers are actually causing genetic mutations. Are vaccines that trigger? Probably not exclusively.

Given the increased rate of occurrence of late onset autism (like my son who displayed no symptoms until age four) it seems that the first scenario is more likely.
