  • Immunological memory is a distinct characteristicof the immune system and it relates to its ability to remember antigens on pathogens, tumour cells, tissue of the immunological self, and cells and tissues derived from other individuals of the species and mount an immunological response of greater magnitude and with faster kinetics upon re‐encounter of the same antigens.
