lolol, "There was a three or four month window, right when the vaccines were first released, when a 95+% implementation of the initial vaccine shot could have produced a reasonably close facsimile of herd immunity, such that it would have made it several orders more difficult for the virus to effectively mutate. It could have conceivably cut the subsequent death toll in half, if not more."

This is a statement that has many claims: 1. 95% implementation (whatever that means) in a specified time window of initial vaccine could've produced herd immunity 2. This herd immunity would've made it "several orders of more difficult" for the virus to mutate 3 The estimate of a 50% reduction in death toll.

I certainly can't remember something that didn't happen, herd immunity that *would've made mutation more difficult" or a "50% reduction" that didn't happen.

Your memory must be better than mine, it remembers statistics and estimates from counterfactual events.
