There is a big problem with optimistically assuming immune systems will respond like SARS even, because we know in general terms the more severe the symptoms the longer the immunity lasts, but wait ... huge huge numbers of people with Covid-19 are asymptotic, that is not the cases with it’s SARS and MERS relatives! wake up people, herd immunity is delusional and dangerous. more likely is very short immunity, just like the other 4 Corona family virus which cause many of our common colds, high asymptotic rates, and reinfect us very very frequently and NOT due to mutations!
