Just for the sake of sheer argument, one might suggest that all these probable scenarios of viral contagions and vaccines might be a bit contradictory.
Round off the effectiveness of the vaccines [all of 'em] to about a 94-95 percentile....yet the true true fatality rate of those infected still holds at 00.01 - give or take a few hundredth of a percent.
The questions still remain if a vaccine is really worthy or just allow all this to play out.
