Yes, zero out of 30,000 is an extraordinary figure. If true, it suggests that vaccinations are not just the major cause of autism but the ONLY possible cause of autism. I suppose it's possible, but it seems odd that nothing else could ever have the same effect, genetic or environmental.

Not Cause. Thats the word that opens the doors for the sophists.

Vaccinations are the major Trigger....

Vaccinations are the major Trigger

Good term. I think we are basically talking about immune reactions, at least in the case of asthma and probably also of autism, if this story is true.

Immune reactions have been intensively studied since the onset of AIDS, but they are still not well understood.
