Even if the non-vaccinators are correct, the vaccinations cause could not possibly "harm or kill" 100 children in one day-care center. If the most dire concerns of the anti-vaccination claims are true you would be harming ~0.000001 child by insisting that all the kids in one day care center or one school be vaccinated for the sake of the child with cancer. In other words, you would be exposing children to an extremely low risk in order to benefit this one child. It is probably at the level of crossing the street in front of the school a few times. Suppose the child with cancer was weak, and having trouble carrying a bookbag, and your child wanted to cross back over the street to help, would you tell your child: "Don't do that. There is a slight chance that a car will come and kill you. Never do anything for anyone that might subject you to any risk, even a one-in-a-million risk."

Put it that way and you see that your view is anti-social hysteria.

As it happens, the non-vaccinators have no case at all. Vaccinations do not cause autism. Of course they do occasionally cause other illnesses and side effects, but the risk that the child will get a serious disease from not vaccinating far outweighs the risk of harm from the vaccination.
