active immunity
long term (stimulates an immune response); includes: naturally acquired active immunity and artificially acquired active immunity
naturally acquired active immunity
part of active immunity; acquired by exposure to live pathogen with symptoms of the infectious disease (caused by the pathogen)
artificially acquired active immunity
part of active immunity; acquired by exposure to vaccine (weakened or dead pathogen) without exhibiting symptoms of the infectious diseases (caused by the pathogen); rapidly mutating viruses require annual vaccinations (influenza) or defy efforts to produce a vaccine (HIV)
passive immunity
short-term (does not stimulate an immune response); includes: artificially acquired passive immunity and naturally acquired passive immunity
artificially acquired passive immunity
part of passive immunity; acquired by injection of antiserum (blood plasma of actively immune person) containing anti-pathogen antibodies
naturally acquired passive immunity
part of passive immunity; antibodies acquired from the mother by fetus through placenta (persist 6 months - 1 year after birth) and by newborn from breast milk
