What term describes the introduction of a killed or weakened form of the disease organism through vaccination?

• A. Vaccine-induced immunity
• B. Viruses
• C. AIDS
• D. HIV

Answer: (A)

Vaccination trains the immune system by introducing a killed or weakened form of the disease organism, which prompts the body to produce antibodies and memory cells without causing the illness. The term for this is vaccine-induced immunity. This is a form of artificially acquired active immunity, since the body actively builds protection in response to the vaccine. The other options refer to pathogens or diseases themselves and do not describe the process of obtaining immunity through vaccination.
