The variants arise from many sources. The main one actually is one that we can control: getting fully vaccinated. We must also continue masking, social distancing, avoiding crowds, etc. The pandemic will evolve into an endemic sooner as long as we keep our guard up. While "getting back to normal" as we used to know it won't ever happen, but, with diligence, we can lighten the load a bit.
It isn't over because to much money is being made, not to mention the government control over people.
