As a mother of a 23 month old dd and a nurse -- DD gets all vaccines on schedule for the same reason I banked her cord blood. I wouldn't be able to live with myself if she got a preventable [or treatable - cord blood] serious illness and I hadn't done all in my power. ASD is in my family, so I didn't discount the very real fears about vaccines either. It was a risk v. benefit analysis in the end, just like all medical decisions. [The risk of penicillin?]When I was preggers, I had all the family get updated pertussis vaccines too, much to their grumbling, for the same reasons - and they were shocked when each of their doc's said that they needed it!
Talk to people who lived through the diseases that we vaccinate for. Diptheria - could you imagine sitting vigil every night over your sleeping child to remove the membrane that might form over the airway? Tetnus - when did you last see someone with lockjaw? My grandfather died at 44 of heart problems caused by mumps from childhood. My grandmother was deaf after rubella in childhood. Meningococcus - I've seen 2 college kids go through the ICU for this - neither came out whole, toes and fingers missing, dyspharthrias, possible anoxic injury. With 3 close girlfriends who've fought and 1 loss from cervical cancer, DD will be getting the HPV vaccine in turn.
