What is the difference between acquired and natural immunity?
Natural Immunity is created by the body’s natural barriers, such as the skin, and protective substances in the mouth and nose, the urinary tract, and on the eye surface. Very young babies have some immunity (natural) properties passed to them by their mother when in the womb, but this only lasts a short time. Not only does the immune system provide protection from infection through natural barriers, but it also adapts itself to provide immunity against infection by “remembering” the infectious microorganism from a previous exposure.
