If there is no herd immunity and no vaccines, then what? Our society is already in a grips of semi-panic, fear, civil riotous turmoil, deep seated hate, etc. Arguably the society is on the verge of a mental breakdown. More shutdowns, business failures, unprecedented unemployment, political insanity, growing homelessness, rising violent crime (shooting, looting, arson, assaults), are not going to help matters.
I think far too many are overlooking all of these problems while mind locked on this virus.
