But here's the thing: One would think that if the older people were worried about getting covid, they would have gotten the vaccine when it became available first. If they aren't worried enough about it to act, then why should others worry about them?
The military is a special case.
Suppose a reservist, in a non-deploying unit, will be out of the military in 3 months, and they don't want the virus...should they be ordered to take it (matter than encouraged)?
