Question

• A. innate immunity
• B. Natural active immunity
• C. Artificial active immunity
• D. Artificial passive immunity

Answer 1

The correct option is C

Artificial active immunity

The correct option is C:

Explanation of correct option:

• When an antigen is introduced to our body through vaccination for the generation of antibodies, to fight against the antigen. This is called artificial active immunity.
• Vaccines for polio and measles are examples of artificial active immunity.

Explanation of incorrect options:

Option A:

• Immunity inherited by a child at the time of birth is called innate immunity.
• Innate immunity provides a self-defense mechanism to our body.
• It is naturally acquired by a person due to its genetic make-up, it is not disease-specific.

Option B:

• When an antigen enters our body naturally from the environment, and then the development of antibodies takes place in our body to resist the antigen. This is known as natural active immunity.
• Example: An attack of chickenpox imparts a life-long immunity.

Option D:

• When antibodies are developed in other organisms for fighting against a specific disease and they are introduced into the body of a person suffering from that disease, the immunity developed is called artificial passive immunity.
• Example: Treatment of snakebite is carried out using anti-venom.

Final answer: The immunity developed in our body due to the vaccination of polio and measles is an example of artificial active immunity.
