Not all vaccines are of equal worth. I once got into a long discussion with my kids' pediatrician, in which he eloquently defended vaccines in general, but at the end he shook his head and said, "well, the chicken pox vaccine...that was sort of forced upon us by the pharmaceutical industry". His point was that chicken pox is not that dangerous a disease, and that exposure to it provides better immunization than the vaccine. But it's a lucrative little industry, and the disease itself is a huge inconvenience to working parents. So it became required, but the motivation was questionable.
Vaccines in general are hugely beneficial, but it's also healthy to question each one. The combination of an overly-protective government and a greedy pharmaceutical industry could be dangerous.
