any small, long-lived lymphocyte that has previously encountered a given antigen and that on reexposure to the same antigen rapidly initiates the immune response (memory T cell) or proliferates and produces large amounts of specific antibody (memory B cell) the agent of lasting immunity.
A cell in the immune system that, when exposed to an invading pathogen, replicates itself and remains in the lymph nodes searching for the same antigen, resulting in a more efficient and rapid response to any subsequent attack.
Note: The creation of memory cells is one of the main goals of vaccination.
