No. Once you are one of those 60% you either die or get immunity.
- tsbinz 7y agoIt depends. The seasonal flu mutates enough between seasons that last year's immunity doesn't help you much. If we're lucky, this one doesn't do that, or it mutates in a way that symptoms aren't as severe (since causing the host to die or to be isolated in ICU is also bad for the virus, so there's evolutionary pressure towards less severe symptoms).

- mpol 7y agoThere are many weaker coronaviruses floating around that give the common cold. We are still getting the common cold from those, so apparently it mutates in a way that our immmunesystem can't stop it.
