Feel free to correct me if I'm wrong here but what I took away from all of the papers on the MRNA vaccines is that they were designed to tell cells to build a protein (spike protein) that would stimulate the immune system to create an antibody that recognized said protein and it was those antibodies that made it harder to become infected with SARS-COVID-2. One of the papers I read compared and contrasted the antibody that Pfizer used in their development vs the one that Moderna used in their development, with the conclusion that the Moderna "provoked" antibody was slightly more effective at preventing an infection from taking hold. And based on that understanding (which may be flawed, please let me know if it is) then having a better 'target' antibody that you are trying to provoke the immune system to create, would make an MRNA vaccine more effective.
