Why does a person suffered once from small pox can not suffer with it again?
When a person suffers from small pox once, the immune system of our body encounters the disease and responds against it. Our immune system remembers the first encounter and response specifically. Theefore, when the next time that particular microbe or its close relatives enter the body, the immune system of the body respond with even greater vigour. This eliminates the infection more quickly than the first time around and we do not aquire the disease.
