History of Immunization in Timeline
Immunization is the process of strengthening the immune system against infectious agents. Active immunization involves exposing the body to a harmless form of an antigen (immunogen), triggering an immune response and developing immunological memory. This primes the immune system, particularly T cells, B cells, and antibodies, for a rapid response upon subsequent encounters with the same antigen. Memory B and T cells are crucial for this swift reaction. Passive immunization, in contrast, involves directly introducing antibodies or immune cells into the body, providing immediate but temporary protection without requiring the body to produce its own immune response.
