Let me inject a little reality here. We dont have vaccines for most of the viruses that plague us, including HIV, the common cold, SARS, MERS, and many more. The flu vaccines have to be remade every year, and they just take a guess at which will be the right strain. If we have a safe and effective vaccine for CoVid 19 before 2021, I will be very surprised. I probably wont get a shot for it anyway. Im not an antivaxxer, but I do think there are problems with some of them.
I meant to write before 2022.
