Karl, I do not know why you think that the Pfizer vaccine is not actually a vaccine. According to the CDC, "Vaccine: A product that stimulates a persons immune system to produce immunity to a specific disease, protecting the person from that disease. Based on the history with SARs, it is is not clear how long antibody immunity will last. I have heard it does not last that long. Long-lasting immunity is based on cytotoxic (CD8) T cells (CTLs). Generating immunity based on CTLs normally occurs when a cell becomes infected with a virus, synthesizes the viral proteins, chops up the viral proteins into peptides and presents these on the surface bound on Class 1 MHC molecules. Using an mRNA vaccine is a way of making cells make the viral protein and chop it up in the same way as if the cell were infected. The end is the same, generating an immune response that confers resistance.
