TL;DR: Repeated doses may be increasing tolerance of the virus (as opposed to neutralizing it).
#^The immunological mechanism of action for lost immunity, a shift to tolerance (and autoimmunity?) from the shotsA paper was published in Science Immunology on December 22, 2022 entitled: “Class switch towards non-inflammatory, spike-specific IgG4 antibodies after repeated SARS-CoV-2 mRNA vaccination” and it explains in wonderful detail how a class of antibody that commands a non-inflammatory response (more like tolerizing) is prominent in people who have been repeatedly injected with the modified mRNA COVID-19 injectable products.
Translation: Instead of the intended pool of spike-specific neutralizing IgG antibodies being dominant in multiply-injected people, a pool of antibodies associated with spike-specific tolerance are dominant in multiply-injected people.
Besides the tolerizing capacity, they also showed that the phagocytic enabling capacities were much reduced overall. These activities lead to clearance of viral pathogens. Reduce them → reduction in viral clearance capacity.
