I think you are wise to wait until 2. A book you may like to read is "What your Pediatrician Won't Tell You About Childhood vaccinations (something like that) by Dr. Stephanie Cave. That may help you make a decision.
My son has had some vacs because I was living abroad and had little access to informaation. He has not has all of them though. If I could do it over, I likely would have only done maybe polio or tetanus.
I would now like to find a way for my son to contract either mumps, measles or rubella during childhood but think it will be very difficult amongst a mostly vaccinated public.
