Question 25.
Question Explanation
The term "banking of immunity" refers to the idea that there is something we could rely upon, this immunity and sort of storing this into the system of society as a whole
Option A is not what the author is saying. The idea of herd immunity is not that people will get a reserve of immunity but that the virus will spread less.
Option B: This, too, is incorrect, as the passage does not state that when somebody is vaccinated, it is a "deposit of protection against a particular disease".
Option C: The idea of multiple vaccines preventing multiple diseases is also not in the passage.
Option D: This is the closest to what the author means by the banking of immunity, that although someone who themselves might not be immune, would benefit from the increased immunity of others and could rely on them to some extent.
Option E: This is a bit extreme of what is presented in D, the idea of herd immunity is not presented as a way to mitigate but likely to prevent or reduce the chances of a disease getting hold.
Therefore, Option D is the correct answer.
