Current COVID vaccines are mRNA, which is unstable and needs -80⁰C storage. And while there are protein-based vaccines, mRNA are easier to update. So I think we'll keep getting those while the virus is evolving rapidly.
They don't all need ultra low temperatures anymore
Moderna can be as warm as -15c
This doesn't have em all, but it shows they've gotten better than the initial ultra low temp requirements.

Good news. Thanks. Still colder than flu but freezers are widespread.
Yeah. Basically, when they were making the vaccines, they were like, Okay, we don't know exactly how warm we can successfully store them at and have them remain good. But we definitively know that if we store them at this incredibly good temperature, it'll stay good. Rather than have people dying while we play around with variables when we don't need to, we'll just do things at the temperatures we know are good, and we'll research and figure out the warmer temperatures later on.. And now it's later on, so ...
They are working on mRNA flu vaccines. At least some of point, that'll be on the market and combinable with the Covid one.
