Document Summary
Body learns and mounts an attack so the next time you don"t fall sick. Injection with an antigen, that way you body can learn and will respond faster nex time. Often there are two hosts, the first host who learned and developed an acquired memory. This information is passed to the second host. This is often temporary and not a permeant memory. Allows the immune system to learn and that during a second encounter the immune system can attack faster. Suspension of attenuated or killed microorganisms or a fraction of these administered to induce an immune response and thus prevent the infectious disease. Goal is to expose you to a harmless version so you can prevent the problems at a second encounter. Modified non toxic version of a toxin which retains its immunogenicity. Will be better prepared at a second exposure. Compound added to vaccine preparations which increases the immune response. Illicit an inflammatory response (second line of defense)
