There is a pretty good chance that the vaccines don’t really work at all and never did. We know the Pfizer Phase 3 trials were gamed in many ways. There is no doubt that the vaccines elevate antibodies, but it seems that it is quite possible that the immunity they confer is actually the result of killing off (or excluding as in the case of the trials) people with weaker immune systems. The people who are left are thus more resistant to the virus.
