When you have measles, it is exactly the same as walking around town with a handful of hypodermic needles, injecting random passers-by with viruses.
How far does that argument extend? Should everyone be required to get all available vaccines, no matter how ineffective and how many risky side effects they have?
The HPV and Varicella (Chickenpox) vaccines now mandated for school children certainly bother me on that front. The first is only a sexually transmitted disease which shouldn't be possible to spread on school campuses. The latter is a rather mild disease for children, while getting the vaccine puts your child at risk for potentially more severe side-effects.
