The story is NOT that mutants are now dominant. The story is cases have come down dramatically.

Tweet prompted by a stream of headlines over the last month like this. 
When what is happening is this.
This is a virus. When a virus replicates in millions of hosts mutations happen. And with time one or more mutant is going to become dominant. Ultimately though the mutant that wins out is most likely going to be one that is more contagious but less severe.
In any case we don't have any better long term sustainable options other than to vaccinate as many people as quickly as possible with whatever approved vaccine is available. That's the solution that is in our control.
So we keep coming back to this. Mutants or not, vaccines will do what they are supposed to do: dramatically reduce severe disease and deaths.
