- Plasticity
- Specificity
- Diversity
- Memory
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The principle of vaccination is based on the immune system's property of Memory.
(A) Memory - Correct: Vaccines stimulate immunological memory via memory B-cells and T-cells.
(B) Specificity - Incorrect: While important, this isn't the basis of vaccination.
(C) Diversity - Incorrect: Refers to antigen receptor variety, not vaccine mechanism.
(D) Plasticity - Incorrect: Describes immune adaptability, not vaccine function.
The correct answer is (D) Memory, enabling rapid response upon pathogen re-exposure.

- Immunity in our body is of two types: (i) Innate immunity and (ii) acquired immunity. Innate immunity is a non-specific defence mechanism, whereas acquired immunity is pathogen-specific; it is called specific immunity too. Acquired immunity is characterised by memory. Antibodies are specific to antigens and there are different types of antibodies produced in our body: they are IgA, IgE, IgG, IgC, and IgM. It shows primary response when it encounters the pathogen for the first time and secondary response during the subsequent encounters with the same antigen/pathogen. Name the two types of specialised cells which carry out the primary and secondary immune response.
