This news comes as some doctors say they have seen patients test positive for COVID-19 after recovering from the virus.
I haven’t personally had any Covid patients get infected a second time. Have any of you?
If so, hopes for a vaccine may indeed be in question. Will have to await trial data. https://t.co/zR3hhh1Skq
