As I understand it, you don't have to vaccinate everyone in a population to prevent an epidemic. The unvaccinated ones will not form a pool of disease unless they all live together! If a few unvaccinated ones are spread out among the population, they won't get the disease, because they won't be exposed to it.
So, let all the high minded liberal do-gooders please themselves by going and getting vaccinated, and tell everyone how conscientions they are, and let a few poor uneducated religious types forgo that option so that they can tell their mates how good they are.
Peace.
