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: Types of Immunity.
Immunity can be categorized as passive and active. - Artificial active immunity is achieved via vaccination with live or weakened organisms, prompting an immune response without causing illness. - Passive immunity involves receiving antibodies from an external source, either naturally (mother to child) or artificially (antibody injections). - Natural active immunity develops after the body encounters and fights a pathogen. - Local immunity targets specific body areas, such as mucosal immunity. Step 2: Summary.
Vaccination with attenuated organisms results in artificial active immunity. Thus, option (1) is correct.
