I would encourage you to actually study the history of vaccinations. Most diseases were subsiding before a vaccination was even produced. Millions of people were exposed to disease and never affected. What was the difference? Immune systems were able to fight off disease in millions of cases. The idea to stab every kid with 20-30 direct diseases straight into the blood stream is questionable. There has to be a balance between supporting the immune system to fight disease and just jabbing every kid with needles full of disease in the believe that it will "prevent" disease.
The more people refuse to have their kids vaccinated, the more chances of epidemics of these once almost completely done away with/controlled break out, as the above article proves.
The ONLY reason that the aforementioned diseases rarely appeared in America, in the past several decades, is due to parents having their kids vaccinated against having them and nothing else.
Immune systems usually fought off repeats of many diseases only after one had had them!
Wait - are you claiming that vaccines do not prevent disease?
