The only thing all libertarians would have issue with is coercing people to take it.Mass immunisation only works because all/most people do it. If everyone waits for a "large history" for a vaccine, they don't work.
Again the public good argument wins, but I know that is irrelevant to a Libertarian.
Do you consider people that have caught the virus, recovered and developed natural immunity as more or less or the same level of risk as someone that has taken the vaccine?
