Vaccinations are interesting, because they provide a kind of network externality. If I get vaccinated against a disease, not only am I less likely to get the disease, you are less likely to get it too, because there are fewer possible incubators.
I'm curious about something, just as a little thought experiment.
There's a contagious disease, the Martian Death Flu. Each individual in society has a chance c(i) of getting the disease - so person number 1 has chance c(1), person 2 has chance c(2), and so on, and these chances are based on a bunch of risk factors: age, ethnicity, income, dietary habits, exercise routines, medical history, etc., which means some people are at higher risk for catching the martian death flu, and some are at lower risk.
For some reason, some people have a negative reaction to the vaccine - a very strongly negative reaction. We'll say the newly developed vaccine for the martian death flu causes reactions as bad as the illness itself in people with probability p. It's a small chance, in the <1% range, but a perceptible chance nonetheless.
Now, some people are going to be at high risk for the martian death flu, and should obviously get immunized. Some people are going to be at low risk, and they would actually be less likely to get complications if they didn't get the vaccine - but if they do catch the martian death flu, they'll raise the likelihood that other people get it. So, what should the government do?
1) Require everyone to get the vaccine, under penalty of fine and/or imprisonment. Despite their objections, those who were at low risk get sick at a higher rate than they otherwise would, and can rightfully blame the government for their miserable lot in life, but it doesn't matter because their misery has prevented the misery of the high risk people.
2) Require everyone to get the vaccine, where those who can show records that they are at low risk pay a lower price to receive the vaccine, or get a small tax break to offset their increased risk of getting sick. In this case, the low risk people get back some of the benefits they give to society.
3) Require only those who are at high risk to get the vaccine, while those who can show records that they are low risk are exempted.
4) Do not require anyone to get the vaccine, but spread information about the risk factors and dangers of illness, so that those at high risk will get vaccinated and those at low risk will not.
5) Whatever other option you prefer, of which there are very many.
