I raised 2 boys who rec'd all their shots on schedule and suffered no serious adverse affects, and I am not personally aware of anybody's children who have, nor have I heard from word of mouth~~friend of a friend thing. The reason is because serious adverse affects are so extremely rare. However, if you want to modify the vaccination schedule, your pediatrician should be willing to work this out with you. If he/she's not, then obviously you need to find another doctor.
As for the poster who said vaccines weren't necessary, they were developed to save lives, and they've done that. Diseases that killed, maimed or crippled thousands to millions every year---smallpox, the various plagues, polio, german measles, TB, etc. With so many parents opting out of the vaccinations, TB in the U.S. is on the rise and has been found in many of our schools, along with a handful of other illnesses that we haven't seen in years. We've become complacent and have forgotten the severity of these diseases that vaccines have protected us from for so many years. However, if we raise a generation of un-vaccinated children, they will re-surface and our children will see the results firsthand---in their own families. For ME, I'd rather have one or two days with a fussy infant!
Hep B can definitely be postphoned til baby is older. It can be transmitted by body fluids contact, which means the obivious.....blood,etc., but also the less obvious....sharing toothbrushes.
