I know the media and WHO keep saying immunity is uncertain but everything I've read says it's highly likely. Covid19 only has 1 surface antigen, the spike protein, which is highly conserved, and the virus as a whole is very stable with a low mutation rate. Nothing like flu or the cold. Plus people who had SARS or MERS keep immunity for years.🤞
From what I read, they think, based on existing Corona viruses acquired immunity is about 2 years.
IF you mount a proper immune response. So is that good enough to reopen with no vaccine, especially as you need lots of people to get sick before you hit herd immunity?
