Immunization

Immunization fortifies the immune system against infectious agents. Exposure to foreign molecules (non-self) triggers an immune response and immunological memory within the adaptive immune system. Active immunization involves controlled exposure to an immunogen, enabling the body to learn to protect itself, primarily enhancing T cells, B cells, and antibody production. Memory B and T cells facilitate rapid responses to subsequent encounters. Passive immunization introduces these immune elements directly, bypassing the body's own production.
