BTW, I am in favor of imunization. I'm not in favor of denying unimmunized children healthcare because their parents did not have them immunized.
Yeah, reading your post, you don't say you are agaist providing care. I'm pretty sure that my response was to a different post. Strange.
Anyway, to answer your questions...
Death by kitchen fire alone is 3x greater than pre-vaccine chicken pox. No doubt that including various other ways people die would increase that number. Even worse is that while 95% of all chicken pox cases were in children, 50% of all deaths were in adults. Then add to it that the chicken pox vaccine does not offer life long immunity, and you have a situation where, for that perticular vaccine, the numbers just don't pan out for childhood immunization. If they offered it to adults who never caught chicken pox as children, the numbers would come out entirely different.
This is why I find it highly irresponsible for doctors to try to scare people into getting 'vaccinations'. Not all vaccinations are created equal, and not all diseases with available vaccines are equally dangerous. When doctors (and anti-anti-vaxers) equate chicken pox with something like polio or small pox, they lose credibility. When they lose credibility, they are far less effective at convincing people to vaccinate against the real threats.
The number of people opting out of mumps vaccines can also be set at the feet of the medical industry. A doctor (you know, one of the 'experts') indicated that the combined mumps, measles and rubella vaccine caused autism. He recommended taking the vaccines seperately. The response from the medical industry was to rely on brow beatings, insults, and lies. They assumed that everyone would just fall into line due to their appeal to authority. If they had just shrugged their shoulders and offered the three vaccines seperately, the movement against vaccines as a group would not have gotten as much of a foothold has it has.
