Worst case 10 years, likely well less than that and coronavirus won’t matter to humans. You see we have what’s called an inate and an adaptive immune system. The inate immune system catches coronavirus and immediately illicits a response, the adaptive immune system catches infections that the inate immune knows about. The innate immune system dies off after you are 10 or 11 and your adaptive immune system catches 90% of foreign invaders over your life.

I’m giving some background because it means kids and children today have antibodies created by the innate system that fights off novel coronavirus. Which means their adaptive system will be able to remember and fight back against this virus. This means mutations, specifically this means weaker general strains in the future akin to the cold/flu.

Let me put it this way.. RSV is a nasty respiratory illness but we as a species survive quite well along side it even if it happens to kill a few babies and old people every year
