> We found, in our 788 confirmed COVID-19 patients, the decreased rate of severe/critical type, increased liver/kidney damage and a prolonged period of nuclear acid positivity, when compared with Wuhan.

So how are we gonna deal this increased liver damage then, if we are actually gonna use this less pathogenic branch of the virus as a quasi-vaccine?

Is there way to reengineer this virus so that it would be less kidney/liver damaging?
