We could just approve Corbevax in the US. It's a more traditional vaccine and includes more of the virus than spike proteins. It's also unpatented and cheap. The cynic in me says there is huge interest in having an annual Covid vaccine like the flu one. They'll just change spike proteins every year in a never ending game of cat and mouse. With mRNA that game is easy and profitable.
> It's also unpatented and cheap All of these vaccines are cheap.
Not if you have to take them several times a year until the end of your life
