Well, the jabs instruct the cells to make copies of the spike protein. Do ALL copies obediently go into the cell membrane and protrude through the surface? Or do any of them get loose?
You are past my ken here, GW; the mRNA vaccine strands generate some SARS-CoV-2 characteristics in order to stimulate antibodies but does the vaccine reproduce the whole virus and all of it's spike proteins? I don't know about that nor whether it weakly duplicates the complete viral infection. That is not my (limited) understanding.
