Flu shots are “updated” every year for new variants. I might be wrong, but I think covid boosters so far are all just extra doses of the same old material. I don’t think anyone would get flu shots if we were expected to get 4 doses of the same thing with demonstrated lower efficacy. I’m perfectly fine with getting boosters if they’re adjusted to be more effective against new strains. Getting a third, fourth, or fifth…
Which is why all of these companies are currently working on "v2" of the vaccine which specifically targets omicron. But since the current version of the vaccine was found the be effective anyway, that's why it's being used. I imagine by the time next year it won't be in use anymore, purely because of its lack of effectivness for whatever variant is around then.
A yearly shot for vulnerable people possibly rolled in with your flu shot (or at least scheduled the same way).
I go get my flu shot every year since I'm classed as vulnerable for health reasons - the exact same reasons I went and got both covid shots and the booster the second I could.
