What baby vaccines are considered "dangerous" and why?

Okay, I'm totally freaked and didn't know you were "allowed" to not have your kid vaccinated. Do you know which vaccines are considered dangerous and if so why? And, our little girl is 9 months old and has already had 3 sessions of shots for DTP, HiB, Polio, Hep B, PCV, and RV. Any info anyone... show more Okay, I'm totally freaked and didn't know you were "allowed" to not have your kid vaccinated. Do you know which vaccines are considered dangerous and if so why?
