It plays a significant role in .Memory is a key feature of adaptive immunity, which allows organisms to respond more readily upon re-infections. The generation of immunological memory is a hallmark of adaptive immunity by which the immune system remembers a previous encounter with an antigen expressed by pathogens, tumors, or normal tissues; and, upon secondary encounters, mounts faster and more effective recall responses.

The time course of an immune response.The natural immunological memory captures the diverse repertoire of SARS-CoV-2 epitopes after natural infection whereas, currently approved vaccines are based on a single epitope, spike protein. Fast functions of effector memory and the superposition of both quantitatively and qualitatively plastic anticipatory memory responses together form the walls of protection against pathogens.Immunological memory is defined as the ability of immune cells to specifically ‘remember’ the first encounter with a given antigen and to mount a secondary response that is faster and greater .

Immunological memory equips our immune system to respond faster and more effectively against reinfections.If monocytes and macrophages develop antigen-specific memory to antigens presented by donor-derived MHC-I molecules, it is likely that these and other myeloid cells can develop immunological memory to self- and nonself antigens of different sources. Memory B and T-cells are antigen-specific and, on encountering the .Macrophage memory is a relatively new concept that is revolutionizing our understanding of macrophage biology and immunological memory and could lead to a new class of vaccines and immunotherapies.2101058
