Immune System Disorders
An immune system is a system of biological structures and processes within an organism that protects against disease. In order to function properly, an immune system must detect a wide variety of agents, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. A vaccine is a biological preparation that improves immunity to a particular disease.
