Types of immunity

Immunity may be a naturalpassive or inherited, that a person was born with. It has a specific character (person does not suffer from murrain disease, and the cattle — from malaria).

In another classification there are also such kinds of immunity: antiviral (usually unstable), antimicrobial (sufficiently stable, depending on the type of microorganism), antitumor. The latter deteriorates under adverse environmental conditions, and various abuses.

Active natural immunity

Active (acquired) natural immunity occurs after a person was sick with infectious disease. Been ill with measles, he would never get sick with it again, and in his body have been produced antibodies that will renew throughout life. This phenomenon is called immune memory.

Artificial passive immunity

Artificial passive immunity creates by injecting ready-made antibodies in the human body, if he got sick of diphtheria, tetanus, and so on. Taken from http://worldofschool.org

Where are the ready-made antibodies taken from? They infect animals, such as monkeys, pigs or horses, with tetanus or diphtheria. Their organisms produce antibodies. Antibodies are taken from the blood of these animals in a special way, and then they are injected into a human in a form of therapeutic sera to prevent the disease or to ease its symptoms.

Artificial active immunity

Artificial active (acquired) immunity occurs when the organism in response to the vaccine produces antibodies by itself against specifically injected attenuated bacteria, viruses or toxins.
