Do we know yet how long the covid vax is good for?

6. They are uncertain

The last article I read about it (NYT or WaPo), had a discussion about post vaccine guidelines. The experts appeared to be at a loss over its time line. The general consensus I got from my read was that just as the flu shot is updated annually with what the expected flu variations will/are, so too would a covid shot.

The big concern was how fast the virus is mutating, and how many different mutations were popping up. It then went into more scientific specs that were above me. The specs had to do with protein on specific spikes, types of mutations, less "sticky" more "sticky", less virulent, more virulent, easier to spread, harder to spread. Umm, mostly they just are uncertain what is going to happen.
