Innate immunity is the immune system that is present when you are born. It is your body's first line of defense against germs. It includes physical barriers, such as skin and mucous membranes, and special cells and proteins that can recognize and kill germs.

Are you born with humoral immunity?

Innate immunity also comes in a protein chemical form, called innate humoral immunity. Examples include the body's complement system and substances called interferon and interleukin-1 (which causes fever). If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system.
