Definition

  • Active immunity is the development of a secondary immune response retained by B-lymphocyte and T-lymphocyte memory cells to confer long-term protection from specific diseases caused by pathogens. Active immunity is achieved through immunization or by contracting the illness and having the body's immune response identify and eliminate the pathogen.
