Acquired or Adaptive Immunity
This is an immunity developed by an animal in response to a disease caused by infection of pathogens. It is very specific and prevents further attacks. It lasts for the whole life of the organism in certain cases and for a few years in others.Acquired immunity is further of two types - natural or active and artificial or passive
Active Immunity
Immunity is said to be active when an organisms own cells produce antibodies. It develops as a result of contact with pathogenic organisms or their products. It may be acquired naturally or artificially. Active immunity is produced naturally by the attack of the disease like small pox or produced artificially by injections and vaccinations.
Passive Immunity
Immunity is said to be passive when antibodies produced in another organism are injected into a person to induce protection against diseases. Passive immunity is developed for rabies, tetanus toxin, or salmonella infection. It has the advantage of providing immediate relief. But it has some problems. It is not long lasting and antibodies may cause reactions.
