Active immunity is the resistance developed by an individual as a result of an encounter with a pathogen. This involves the active functioning of the person’s immune apparatus leading to the synthesis of antibodies and production of immunologically active cells. Active immunity is long-lasting, slow, and is associated with immunological memory. The initial immunity is of low intensity called the primary response. On subsequent exposure, the immune response occurs more quickly and abundantly and is known as a secondary response.
