Natural acquired immunity is when your body already knows how to defend against certain antigens and germs.
Artificial acquired immunity is provided in shots to the body when we are babys. These shots contain inactive or a weakened antigen or germ in order to allow are body to produce an anti-body to defend against them if we were to get infected in the future. This makes them alike because the way of defending against the antigens are the same. The only difference is that in artificial immunity are bodys are introduced to a foreign antibody in order for our body to "learn" to defend against it.
Passive immunity occurs when your body is provided with antibodies it did not itself develop, as with transfer of antibodies in breast milk. Active immunity occurs when the person has developed its own antibodies as a result of infection in its own system.
