For all the talk on how its important for everyone to get vaccinated, not a single country has so far made the COVID vaccine mandatory for adults. Some states are making it mandatory for college students but none are planning to enforce it for other groups of adults. Even China isn't making them mandatory despite them having little respect for human rights otherwise and no courts to limit the power of the government.

So where does this reluctance come from? At least in the US such a law would be constitutional so the decision not to go ahead with such a mandate is purely political.
