Furthermore, a novel approach referred to as allo-priming which utilizes TH1 like cells derived from the donor (AlloStim) in order to reduce imflammaging and immunosenescence in elders. This proposed method basically increases the antiviral immunity via creation of a large amount of allospecific Th-1 memory cells. When these cells are exposed to viral attack, they release IFN-γ in order to initiate the antiviral response. This approach is capable of producing a broad protection against viral infections such as variants of Covid-19. Moreover, this approach might be utilized as a backup strategy when other vaccines fail. Beyond that, it might also enhance the elderly care as well as preparedness of a future pandemic and might serve as a universal anti-viral vaccine (Har-Noy & Or, 2020).
