Question

Vaccination is an example of __________:

Options
  • A

    Natural passive immunity

  • B

    Natural active immunity

  • C

    Acquired active immunity

  • D

    Acquired passive immunity

Explanation

Vaccines are antigens injected into the body (artificially) but our body cells are the ones producing antibodies. Hence, this is an example of acquired active immunity.

Vaccination is neither a natural immunity nor a form of passive immunity. They generate active immunity, and it is an example of acquired immunity, so the option is incorrect.

Although vaccination is a type of active immunity, it is not a natural immunity because it is not present from birth. Hence, this option is incorrect.

Vaccines are antigens injected into the body artificially but our body cells are the ones producing antibodies. Hence, it is a type of acquired active immunity. Hence, this option is the correct option.

Although vaccination is an acquired immunity, it is not a passive immunity. It is an example of active immunity, so this option is incorrect.
