Immunology

Immunology is the study of how your body defends itself against invaders like bacteria, viruses, and other harmful substances. It focuses on the immune system, a network of cells, tissues, and organs that work together to detect threats and eliminate them while ideally leaving your own healthy cells alone. Understanding immunology helps explain everything from why vaccines work to why some people develop allergies or autoimmune diseases, where the immune system mistakenly attacks the body's own tissues.
