I think COVID is now considered endemic globally, it's more manageable than it was when it first broke out but it still causes deaths and weird after effects, probably not as many as before but will probably stay with us for some time to come.
It may be better to do what we do with the flu, reevaluate the vaccine from time to time, and give the new version to everybody.
But also, around here covid seems to be a smaller problem than influenza, by a rate of 2 if you count only deaths. So it's understandable why people don't want to mess with it.
