I'm coming late to the discussion, but I am a Mom who made the decision to vaccinate after a lot of careful consideration and research. My family medical history includes several cases of family members who had serious complications from vaccine preventable diseases, so that factored into my decision.
My son was born with autism. Vaccines had nothing to do with it. He also has several other genetic conditions, including albinism and a rare chromosome anomaly. He also had developmental issues in the womb (cystic hygroma).
(And before anyone asks: No I did not get any vaxes while pregnant - I had colds all during flu season, so I wasn't able to get the vax. And No, DS did not get the Hep B at birth - at the time our doc routinely gave it at the 2 month check up.)
I have no regrets for vaccinating my child and I respect the decisions that other families make for their kids.
