WebThe two major types of immunity are: Innate Immunity or Non-specific Immunity. Acquired Immunity or Adaptive Immunity. Innate Immunity Innate immunity is present in our body by birth. This immunity includes certain defence mechanisms that do not allow the particles to enter our body. WebIn disease: Immunity …there are two types: nonspecific, innate immunity and specific, acquired immunity. Innate immunity, with which an organism is born, involves protective factors, such as interferon, and cells, such as macrophages, granulocytes, and natural killer cells, and its action does not depend on prior exposure to a pathogen.
