چکیده
Vaccination is the injection of antigenic material, such as pathogen derived foreign proteins and toxic adjuvants into the body, to initiate a “learned” immune system response in order to prevent particular diseases. Memory T cells (cell-mediated immunity) and Memory B cells (humoral-mediated immunity) learn to respond more quickly and strongly to specific infectious agents. B lymphocyte cell response to infectious agents are dependent on intelligence from memory T cells which serve as “helpers” aiding in the recognition of intrusive pathogens by signaling to B cells to produce “high affinity antibodies”.
