Your primary immune response, or innate immunity, is how your body responds the first time you encounter a pathogen (e. g., a cold virus). The chances of you having antibodies for a new virus are almost impossible. On your first exposure your body will make antibodies, but it will take awhile. First Line of Defense Your primary immune response is carried out by white blood cells, which are always circulating around in your blood whether you are battling an infection at the moment or not.

But every once in awhile a virus cell wins and keeps the macrophage from destroying it. The virus then hijacks the macrophage and reproduces inside it. The macrophage then becomes a
