One vaccine is good. Is two better?
I know they are supposedly studying this type of stuff. But scientists, can you tell me theoretically what the answer is to the following?
1) Would a 2nd vaccine be better than just 1? Or could it somehow hurt you and your immunity?
2) If the answer to #1 is yes, would it theoretically be better to get the same type of vaccine (another MRNA) or would it be better to go to Johnson and Johnson?
