Early immune response refers to innate immunity, which is the first line of defense. Innate immunity is a non specific defense mechanism that comes into play immediately or within hours of an antigen’s appearance in the body. These mechanisms include physical barriers for example skin, chemicals in the blood and immune system cells that fight off foreign cells in the body. The innate immune response is activated by chemical properties of the antigen. Late immune response refers to adaptive immunity, which is an antigen specific immune response. The adaptive immune response is more complex that the innate. The antigen first must be processed and recognized. Once an antigen has been recognized,
