Is There a Pan Corono Virus Vaccine?

There is a very strong effort right now in many quarters to create a pan corono virus baccines. There will be different approaches of trying to put in a mix of different types, or of trying to find parts of the virus that are more conserved where immunity will be effective. So i think it's a very worth while effort, and we have to see if it works. I hope we don't need too many more but my guess is we will be king in one form or another.
