If it generates this strong of an immune response, it would seem the second shot may not be necessary for some. My sister had only a sore injection point after Moderna shot #2, perhaps she needed it more than others since it didn't set her immune system over the edge?
There is talk that if you had Covid you may not need a second shot, a triple shot at attacking your immune system, specific to this protein spike, may not be necessary. Heck, the first shot may not really be needed if your body built up a strong immunity just from the actual illness.
I assume in a year they'll have a big study result stating who would need 1 vs 2 vs 0 shots, but for now dealing with these issues.
I'm probably oversimplifying it, but my thought is if you have this strong of a reaction then you are going to be SOLID as far as actual immunity to the illness. The vaccine is working, maybe too well, but its working.
