Covid, in one form or another, is likely going to be with us for the foreseeable future. So long as millions consider it a hoax, or a government conspiracy, etc., its just going to continue to mutate and infect/kill huge numbers of people.
The scientists are in a constant cycle of playing "catch up", and as soon as they find a treatment for the current variant, another will be coming. The only thing most can do is use masks, avoid crowds, and Maybe even get multiple boosters in coming months/years.
