Question

Induced active immunity is immunity that:

A. Is genetically predetermined and is present at birth
B. Begins to develop after birth and is continually enhanced by exposure to new pathogens and antigens throughout life
C. Is achieved. Through a vaccination given to generate and immune response that results in the development of antibodies specific for the injected antigen.
D. Results from a direct attack of a foreign substance by specialized cells of the immune system.

Answer 1

Induced active immunity refers to the immunity obtained through vaccination, where a weakened, dead, or partial pathogen is introduced to stimulate the immune system to produce antibodies and memory cells, providing protection against future infections caused by the same pathogen.

Step-by-step explanation:

The correct answer to the question 'Induced active immunity is immunity that' is: C. Is achieved through a vaccination given to generate an immune response that results in the development of antibodies specific for the injected antigen.

Induced active immunity is a form of immunity where the immune system is stimulated to fight off a specific pathogen by introducing a vaccine into the body. This vaccine contains a weakened or dead pathogen, or specific parts of it, which will not cause the disease but will provoke the immune system to respond. This mimics a true infection, thus the immune system will develop memory cells that can quickly mount a defense if the actual pathogen is encountered in the future.

There are significant advantages to this method, such as the controlled eradication of diseases such as smallpox and the significant reduction of diseases like polio, measles, and whooping cough through widespread immunization programs.
