As for there being more risk than benefit with vaccinations, I think that is entirely untrue. Vaccines have been proven to reduce the RISK of many deadly childhood diseases (although they are not 100% effective...but is anything?). They are effective enough though to warrant government subsidies, WHO recommendation and vaccine programs in almost all developed countries. In fact, if more children in undeveloped nations had access to the kinds of vaccines we do, they wouldn't be such a high morbidity/illness rate from diseases such as polio.
One of the problems here though (and a little bit of a tangent here), is that kids in underdeveloped countries are at higher risk to the side effects because their immune systems are already so low. A mass vacc in the Philippines blew he death rate for the same diseases through the roof.

The man who discovered the Polio vaccine readily admitted the cause of the cause in 100% (I think) of the cases sometime in the 60's was his own vaccine....
