The idea that the Covid vaxxes may result in a lower immunity through “original antigenic sin”/immune imprinting, has been advanced for some time by Covid vax critics. The idea is that an initial exposure to a virus shapes responses to latter exposures to related viral strains. Indirect evidence for this hypothesis, with respect to the Covid vaxxes, comes from data from the U.S. Centers for Disease Control and Prevention (CDC), that people who got two or three Covid jabs are more likely to get ill with Covid six to eight months after the last dose than had they gotten none at all, indicating some sort of immunological priming of the immune system. The push for continuous boosters will merely add to this problem.
