It used to be done this way, however. (I had the small pox vaccine at school the rest at the doctor, and I needed a doctors note to attend school showing that I was vaccinated)
1) Spend the money on public health
2) make it mandatory, with specific medically approved exemptions.
3) Viruses and bacteria are really excited about the religious exemptions
I do believe that people have forgotten the serious nature of disease, because of the success of the vaccination programs. (No or limited personal experience of the diseases themselves)
