The artificial antibodies will bind onto the antigens and that will initiate a response in which it will label those antigens as well as the pathogen for destruction by our white blood cells. Now, one very important point about passive immunity, once again, is it does not develop memory cells. And so this means that eventually these antibodies will be degraded inside our body and they will cease to exist. And at that point we will lose our immunity. And that's exactly why this is called passive immunity. It only persists for several months following injection of those antibodies while active immunity usually persists for the duration of our lifetime.
