Anti-venom, Rabies vaccine (* it is not a vaccine, it is preformed anti rabies antibody) Immunity and its types: Innate and Acquired immunity Immunity is derived from Latin word “immunis ” which means free from burden. Synopsis: In this lecture we will review basic concepts in immunology, including the cells of the immune system, the innate and adaptive immune responses, and the basis of vaccination Outcomes: You should be able to describe the fundamental concepts of immunity including an overview of innate immunity, adaptive immunity, and Contrast host innate resistance with adaptive immunity 2. The immune system is intended to recognize and react to itself antigen in a coordinated fashion. Innate works with adaptive immunity Innate (non-specific) Adaptive (specific) Barriers.
