Question

The immunity acquired by inoculation of living organism of attenuated virulence is called ......... immunity.

• A. Artificial active
• B. Passive
• C. Natural active
• D. Local
• E.

Hint:

Vaccination is a key example of artificial active immunity, where the immune system is exposed to a weakened pathogen to build immunity.

Answer 1

The Correct Option is A

Step 1: Understanding types of immunity.
Immunity can be classified into several types, including passive and active immunity.
- Artificial active immunity is acquired through inoculation with a vaccine containing live organisms or their components with attenuated (weakened) virulence. This stimulates the immune system to produce an immune response without causing disease.
- Passive immunity is the transfer of antibodies from an external source, either naturally (from mother to child) or artificially (through antibody injections).
- Natural active immunity occurs when the body is exposed to a pathogen and develops immunity after infection.
- Local immunity refers to immune responses at specific body sites (e.g., mucosal immunity).
Step 2: Conclusion.
The immunity acquired through inoculation with an attenuated organism is classified as artificial active immunity. Therefore, the correct answer is (1).
