The cost-benefit analysis on vaccination shows that it is not a huge benefit to the individual as long as everybody is doing it however it is a huge benefit to the society if everyone can be coerced in to doing it even though the decision is not a huge personal benefit. It is a classic example used in economics and if you have an issue with it, you basically are rejecting all rational modern economics. So, have fun with your faith based arguments, not much else to say.
