- you get outbreaks of measles What is a base of this hypothesis? - why anyone would prefer to let their childs body be ravaged by all kinds of exotic viruses rather than protect them with the generally gentle and safe vaccines. If there is no reasonable possibility to get in touch with that virus, why should you "put" it in body of your health child by medical intervention that is based on irrelevant fear? But it's choice that every parent can freely make. Should we all be vaccinated against for example malaria?
