In terms of the human body, an innate immunity means that the body will fight and attack anything that is foreign and does not belong. The most important part of this feature is that since it does not discriminate, the immune system is able to handle risks quickly.
Most live attenuated vaccines (influenza vaccines in humans, infectious bronchitis and Newcastle disease vaccines in chickens are types that activate innate immunity responses.
Innate Immunity Innate Immunity is a form of non specific host defense against invading bacteria. It is natural or "innate" to the host, depending, in part, on genetics. Innate defense mechanisms are contitutive to the host, meaning they are continually ready to respond to invasion and do not require a period of time for induction. The most important components of innate immunity are anatomical barriers, intact normal flora, tissue bactericides including complement, and ability to undergo inflammatory and phagocytic responses. Innate immunity provides the first line of defense against invading bacteria. The skin and mucous membranes provide physical and chemical barriers to infection. The normal bacterial flora antagonize colonization of body surfaces by nonindigenous bacteria. The internal tissues invariably contain bactericidal substances. The most noteworthy antibacterial substance is the enzyme lysozyme, which is present in mucus and all bodily tissues and secretions. If these barriers are penetrated, the body contains cells that respond rapidly to the presence of the invader. These cells include macrophages and neutrophils that engulf foreign organisms and kill them. Bacterial invasion is also challenged by the activation of complement in blood and tissues and the incitement of an inflammatory process which has the tendency to focus both the innate and adaptive immune defenses on the site of invasion.
