8A - Acquiring Immunity Flashcards
active immunity
Protection against a disease created by antibodies and memory cells formed by a person’s own adaptive immune system.
natural immunity
Protection against a disease formed without medical intervention.
artificial immunity
Protection against a disease formed as a result of medical intervention. AKA induced immunity.
passive immunity
Protection against a disease created by antibodies from an external source.
natural passive immunity
Protection against a disease created by antibodies from an external non-medical source. AKA naturally acquired passive immunity.
artificial active immunity
Protection against a disease created by antibodies and memory cells produced by an individual’s own immune system after medical intervention. AKA artificially acquired active immunity.
vaccine
A medical treatment typically containing antigens designed to stimulate a persons’s adaptive immune system to create immunity to a pathogen without actually causing disease.
primary immune response
The reaction of the adaptive immune system to an antigen it has not previously been exposed to.
secondary immune response
The heightened reaction of the adaptive immune system to an antigen it has previously been exposed to.
vaccination program
A series of vaccinations designed to create long-term immunity to a disease. AKA vaccination schedule.
booster vaccine
A vaccination given to a person later in time after they have completed their initial vaccination program to enhance their existing immunity against a disease. AKA booster shot.
artificial passive immunity
Protection against a disease created by antibodies from an external medical source. AKA artificially acquired passive immunity.
antivenom
A medical treatment containing antibodies specific to the toxins in venomous bites or stings.
herd immunity
Protection against a disease conferred to non-immune individuals when a high percentage of a population is immune to the same disease. Herd immunity is often achieved through high rates of vaccination.
