When the virulent version of an agent is encountered the body recognizes the protein coat on the virus and thus is prepared to respond by first neutralizing the.

If you are immune to a disease you can be exposed to it without becoming infected. Upon detection of these agents or events the innate immune system activates cells to attack and destroy the outsider or to initiate repair while also informing and modulating the adaptive immune response that follows this first line of defense.
