People protesting against vaccinations could do well to study the history of them. Since mid 18th century several dozen major diseases have been successfully treated and some eliminated. Vaccinations are extremely successful and serious problems are very rare. Mild unwanted effects, if any, very quickly disappear. The recent measles outbreak is an example of what can happen when vaccinations fall behind or are refused. Yes, dozens of dead children! Refusing to be vaccinated without a very valid reason seems to me quite selfish and refusal does not warrant support.
