I think it requires 70 or 80 percent to be vaccinated before showing effectiveness? Maybe it's run its course naturally .
My 2 million number was for the US alone.

It has to have an R0 below a 1 to decrease spread.

Social distancing and masking drops the R by some amount.
The number of people infected with immunity drops it some more.
Current vaccinations drop it by an additional amount. (At least 10% of the population has had at least 1 dose)

Add those three together and the R is less than 1. Spread decreases.
