IMMUNITY AND IMMUNE RESPONSE

Mrs. Dhiraj Rani

Abstract :

The immune system defends people against germs and microorganisms. Immunization is the way to trigger immune system while Vaccination is the administration of antigenic material to produce immunity. Humans have three types of immunity i.e. Innate, Adaptive (active), and Passive. The immune system attacks infectious organisms and substances through a series of steps called the immune response. The immune system provides three lines of defense i.e. First, second and third line of defense i.e. Non-specific barriers, leucocytes (white blood cells), the specific immune response respectively. The immune response, which occurs after initial exposure to disease or antigen is known as the primary response. The immune response to a booster dose of the same Ag is known as secondary response. The production of memory cells during the primary response helps the body to destroy the re-invading antigen before a person starts to display symptoms
