Comprehension
Read the following passage and answer the THREE questions that follow.
If we imagine the action of a vaccine not just in terms of how it affects a single body, but also in terms of how it affects the collective body of a community, it is fair to think of vaccination as a kind of banking of immunity. Contributions to this bank are donations to those who cannot or will not be protected by their own immunity. This is the principle of herd immunity, and it is through herd immunity that mass vaccination becomes far more effective than individual vaccination. 
Any given vaccine can fail to produce immunity in an individual, and some vaccines, like the influenza vaccine, are less effective than others. But when enough people are vaccinated with even a relatively ineffective vaccine, viruses have trouble moving from host to host and cease to spread, sparing both the unvaccinated and those in whom vaccination has not produced immunity. This is why the chances of contracting measles can be higher for a vaccinated person living in a largely unvaccinated community than they are for an unvaccinated person living in a largely vaccinated community. 
The unvaccinated person is protected by the bodies around her, bodies through which disease is not circulating. But a vaccinated person surrounded by bodies that host disease is left vulnerable to vaccine failure or fading immunity. We are protected not so much by our own skin, but by what is beyond it. The boundaries between our bodies begin to dissolve here. Donations of blood and organs move between us, exiting one body and entering another, and so too with immunity, which is a common trust as much as it is a private account. Those of us who draw on collective immunity owe our health to our neighbors.
Question: 1

Based on the passage, which of the following CANNOT be concluded?

Updated On: Nov 26, 2025
  • A vaccine cannot guarantee immunity in an individual.
  • Our survival, as a community, is largely based on herd immunity.
  • A vaccinated person may get infected if her surroundings are largely unvaccinated.
  • Collective immunity protects those with compromised immune systems.
  • Even, relatively, ineffective vaccines can stop the spread of viruses if enough people are vaccinated.
Question: 2

Why does the author think about vaccination as a “banking of immunity?”

Updated On: Nov 26, 2025
  • Because it creates a reserve of immunity within a person’s immune system.
  • Because when somebody is vaccinated, it is a deposit of protection against a particular disease.
  • Because different vaccines contribute to a diverse portfolio of immune defences.
  • Because it is like providing a safety net for those who are more vulnerable to diseases.
  • Because it is a way to mitigate health risks for those who may not have access to vaccination.
Question: 3

Based on the last paragraph of the passage, which of the following would the author BEST agree with?

Updated On: Nov 26, 2025
  • In times of health crises, communities should come together to support and protect each other.
  • It is important to express gratitude to those who contribute to the herd immunity by getting vaccinated.
  • It is an ethical obligation of individuals to get vaccinated for the greater good.
  • In any community, immunity is transactional.
  • Immunity of a community is interconnected, and everyone plays a role to keep each other healthy.
