Which of the following does not induce any acquired immunity?

A. Inactivated vaccine
B. Injection of antibodies for the toxin or virus
C. Attenuated vaccine
D. Getting an infection
E. None of the above



Answer :

Final answer:

Inactivated vaccines do not induce acquired immunity due to lack of active infection and weaker immune response compared to live attenuated vaccines.


Explanation:

Inactivated vaccines do not induce acquired immunity against a pathogen because they do not cause an active infection, resulting in a weaker immune response compared to live attenuated vaccines.

This type of vaccine typically triggers onlyhumoral immunity and requires higher doses with multiple boosters. It cannot be transmitted to others and may cause inflammatory reactions at the injection site.
