@BowsacNoodle @Shadowman311 And that, along with expense, is why we don't try so hard to give everyone a flue vaccine dose every year. You must always think about these things from an ecological viewpoint, different strains, virus families, etc. fighting it out in whatever domain. See how the 2020-2021 flu season basically didn't happen in the US.

And so we focus on the most vulnerable, the young (not sure how young until it's not such a big deal), the elderly, and the otherwise extra vulnerable. And it still kills a fair number of reasonably healthy adults, and hits others like a freight train as happened to me in very early adulthood once.

And we don't try super hard to get all of those; it's a "best effort" vs. EXTERMINATE!!! EXTERMINATE!!! That will have to wait on a sterilizing vaccine, assuming one is even possible.
