That's not entirely true. The flu has a vaccine (of varying efficacy -- 10-60% depending on the year). The flu also has a large body of immunity built up across the population from having had it. It's also less contagious.

If we assume that COVID is spreading like wildfire (it is), and that we're front-loading the cases (we probably are), and that immunity will be built up as one-off instead of like having the disease mutate substantially every year like the flu, over a few years, it could easily be better.

I'm not saying it is or isn't, just that there is a path.
