By the time a vaccine is availability, herd effects will have resolved the pandemic

I have predicted for some time that general vaccine availability would be in Q2 of 2021, however I am an idiot so what do I know?

President Donald Trump predicted Friday that the U.S. would make available to all Americans a coronavirus vaccine “by April.” That estimate is at odds with CDC Director Robert Redfield’s prediction Wednesday that a vaccine probably would not be widely available to Americans until the summer or fall of 2021.

Then again, almost everything said turns out to be inconsistent, contradictory, incoherent nonsense. Never seen an entire field of study shoot itself in the head like public health has done.
