The immune system is a network of cells and organs that work together to defend you against disease. It stops infections by bacteria or viruses and keeps the body disease free. The immune system has a powerful "search and destroy" task force. It sends immune-cell forces out to hunt down the unwanted intruders and get rid of them.

How Does It Work?


The human body makes proteins called antibodies in response to antigens carried by bacteria, viruses or foreign cells. They help fend off common ailments like the flu or a cold. The immune system also protects against major illnesses like cancer or heart disease. The "cell-mediated immune system helps the body create memories of past defenses against certain threats. So when the body encounters the same invader again, it calls up that memory and destroys the threat before the disease develops. This phenomenon makes vaccines or immunizations work for illnesses like the flu, measles, chicken pox, or hepatitis. The shot has a small but harmless amount of the disease organisms in it so that the immune cells can react, learn, and remember how to protect you from it next time.
