I don’t believe a vaccine has ever been creared that deals with a corona virus. That may be because most coronas are like colds and the ones that were dangerous like SARS disappeared. But I will believe a vaccine when I see one administered.
Bkmk-19
My guess is they will develop a vaccine than deals with their best guess of the strains that will go around in the coming flu season of both the flu and C-19 if it doesn’t disappear from the world.
