My personal opinion is that we should strive to create antidotes when the body fails to fix itself, instead of removing the threat altogether. Evolution needs viruses, in the same way the universe needs entropy.

The question is do we need the blind god of evolution.
endogenous retroviruses in mammals are amazing. primates owe to one or more ERVs the effectiveness of the p53 gene activation (p52 is a tumor suppressor gene).
But the cost for individuals is tremendous, 99.9999999% cases the infection would not be beneficial.
Perhaps in a short while we can do much better ourselves, it certainly seems we humans want to transcend evolution and death.
Yep, if nothing else, we need them to "train" our immune systems.
Treating the coronavirus as a flu would be a best option... vaccinate the most exposed and vulnerable groups, and let others get it.
