History of Immunization in Timeline
Immunization fortifies the immune system against infectious agents. Exposure to foreign molecules (non-self) triggers an immune response and develops immunological memory, a function of the adaptive immune system. Active immunization involves controlled exposure to an immunogen, enabling the body to learn self-protection, primarily improving T cells, B cells, and antibody production. Memory B and T cells ensure a rapid response upon subsequent encounters. Passive immunization, in contrast, directly introduces these immune elements into the body, bypassing the body's own production.
