Question

Which of the following statements is incorrect regarding Vaccination and Immunisation?

(a) Immunisation is the phenomena of increasing specific antibody production

(b) Vaccination is the process of inoculation of harmless antigenic material into the healthy person

(c) A single vaccination gives adequate immunity and lasts lifelong

(d) Immunisation is carried out through vaccination and injection of antiserum

The question was posed to me during an interview.

This is a very interesting question from Human Health and Disease topic in chapter Human Health and Disease of Biology – Class 12

Answer 1

Correct choice is (c) A single vaccination gives adequate immunity and lasts lifelong

The best I can explain: A single vaccination gives adequate immunity and lasts lifelong is the incorrect statement. It may not give adequate immunity. Therefore, 2-3 booster doses of vaccine are administered later on at specific intervals.
