Why the annual flu shot then? All the various strains/mutations?

By my limited understanding, yes, influenza, like many other viruses, mutates quickly enough that you need new antibodies each year when transmission is highest. Basically the vaccine helps stamp down the most common strains that year.
I'm not sure myself how the coronavirus vaccine works, but I recall hearing about multiple strains, so I would think the vaccine would still be a good idea for those that have had covid.
