        Can I then conclude that a vaccine is not necessary if you have already had covid? The chance of reoccupation is already small and suppose it happened, the chance of serious turnover is minuscule. what is the added value of vaccination?

        This study also wasn’t delta, it was alpha/beta. The population was mainly under 50. Just a lot of caveats that should be stated.

        Meaning, there was no need to vaccinate against c19. Herd immunity wouldn’t have created mutant variants (vaccine escape pressure) which turned out to be much, much, deadlier.
