@comrade_Comrade Because a vaccine can be made to target the virus on the basic level, the cases of people getting sick again is assumed to be because of small mutations in the virus, but a normal vaccine can cover a lot of the mutations.

But it is quit possible that this virus is like the flue, and we will have to get a shot of vaccine each year.
