There is in fact a conventional vaccine for Covid, but most people are not aware nor do we have access to it. The inventors did not patent it but made it a gift to the world. Buy hey, money and "do as I say". Oh it's called Corbevax.

Thanks, but it came late in the game (end of 2021).

I think there was also a open source Covid vaccine from MIT but I can't find a reference.
