I suspect a vaccine might be necessary to develop herd immunity. I don't think we know enough about the virus yet to determine if herd immunity may be acquired naturally through infection. There is hope, but folks talk about it like it is a sure thing.
Perhaps a vaccine, yes.
Perhaps acquired through infection, yes.
Or perhaps the desired effect would be a combination of both.
Infection weeding out the undesirables of the old, infirm, and compromised who will surly die once infected and then the miracle shot to save the rest of humanity.
It is a certainly we, as country, cannot sustain 12 to 18 months of house arrest before we implode economically.
Sooner or later someone will need to take the bull by the horns and make a decision.
I still think things will get better on Nov. 4.
