Vaccines and COVID-19 – Lecture in a Box

Published January 19, 2021

Scientists have produced effective vaccines against SARS-CoV-2, the virus causing the worldwide pandemic of COVID-19. The speed with which the vaccines were produced is unprecedented, and that makes some worry that they were “rushed through” and may not be safe or effective.  This mini-lecture reviews vaccine biology and discusses how the current vaccines were made and assessed and discusses their safety profile now that they are being administered to the public.

Below you will find three multiple choice questions that you can use to test your students on their knowledge after viewing the lecture.

MC Questions for “Vaccines and COVID”

  1. Which of the following is a characteristic of adaptive immunity?
    1. It mounts an immediate, effective response after initial exposure to antigen.
    2. It has a separate response for each antigen it encounters.
    3. It results in tolerance to foreign antigens.
    4. Once activated it stays “on” for the life of the host.
  2. By the time a vaccine is released to the public, it has been tested in
    1. a handful of people.
    2. dozens of people.
    3. hundreds of people.
    4. thousands of people.
  3. Herd immunity to COVID will be achieved when
    1. between 60-80% of the population is vaccinated.
    2. the elderly population is vaccinated.
    3. 100% of the population is vaccinated.
    4. 100% mask compliance is achieved.
