I vaccinate. We're on schedule, BUT i'm in the UK and the vaccines and schedule are pretty different here. If i were in the US i'd be selective and delayed, simply because many of the routine vaxes there i don't think are useful. One of the good side-effects of the NHS having so little cash is that the vaccines it does offer need to be cost-effective, so each addition to the schedule is weighed differently.
I have never read anything compelling to make me think i shouldn't (and i read everything i could find, including things with words like "guinea pig" and "conspiracy" in the titles). I'm comfortable with my decision but believe that for some families there is a definite case for not vaccinating and believe every family should be able to decide for themselves. I have friends who choose not to vaccinate and in a way it works great for both of us, because she sees my kids are fine after vaccines, i see hers survived whooping cough just fine. It's a good reality check to remember the best decision for me might not be the best for another person and that in this, as with so so many other parenting decisions, there are no absolutes.
There is autism in my family, none of those who have it were vaccinated on the modern schedule (too old) and so i neither fear autism nor would have a justifiable case for saying a vaccine caused it (when the genetic links are so strong). I had a childhood friend die of measles so herd immunity does play into my thinking. My kids have had reactions along the lines of a sore injection site, nothing worse. I myself had the DTaP last Tuesday as i'd been scratched and pricked up terribly in the garden and not had a tetanus for 18 years! I have a hard sore bruised lump, about what my kids get, possibly a little worse in me.
I find it depressing how much people seem to argue on MDC about this topic.
