Thanks for your thoughts.

I don’t know how many epitopes are targeted by the vaccines. I have often seen the singular “spike protein” used (but “journalists”).

I did see a report that Walter Reed was researching a general purpose coronavirus vaccine, with multiple targets, to cover broad ranges of sub-types or mutations. That was just developmental though.

Maybe mixing and matching the vaccines might be helpful, if they target different epitopes.

This NCBI article discusses the matter in much greater detail. It's a hard bit of reading and I don't have time to read it with the level of attention it needs but I am getting the impression that the mRNA vaccines will stimulate the body to produce antibodies against multiple epitopes which suggests a longer lasting immunity. I'm going to come back to this article this weekend and spend a couple of hours with it.
