Which term indicates immunity that is acquired via exposure to vaccination?

• A. Artificially Acquired Immunity
• B. Naturally Acquired Immunity
• C. Blood-Borne Disease
• D. Chain of Infection

Answer: (A)

The idea being tested is how immunity is gained when vaccination is involved. Vaccines introduce a safe form or a part of a pathogen to the body, which makes the immune system respond and build memory cells. This creates protection without the person having to suffer through the illness. Because this protection is engineered by humans through vaccination, it’s called artificially acquired immunity, and it’s a type of active immunity since the body actively produces antibodies and memory in response to the vaccine. Naturally acquired immunity, by contrast, comes from actually having the disease and recovering. The other terms—blood-borne disease and chain of infection—describe disease transmission and epidemiology rather than a type of immunity.
