Another significant concern surrounding the use of blood from individuals injected with the mRNA COVID-19 jabs is immune dysfunction. Undoubtedly, gene-damaging jabs have the potential to lead to immune-related complications, including immune imprinting, antibody-dependent enhancement, and alterations in immunoglobulin class switching. These phenomena can influence the immune system’s response to subsequent infections, potentially increasing susceptibility to specific pathogens or autoimmune reactions. Significantly, with the spike protein still detectable in the bodies of injected people several months after getting the jab, the risk of immune imprinting is most likely higher than in conventional vaccines
