Free vaccine trivia game, Just the Vax, is now available

The Vaccine Education Center is always trying to find new and unique ways to communicate about vaccines, so we are pleased to announce our newest tool, Just the Vax: Vaccine Trivia.


The trivia game offers players multiple choice questions, such as those above, in four categories:

  • Vaccines
  • Vaccine Safety
  • Vaccine-Preventable Diseases
  • Famous and Historical Figures

Screenshot of Just the Vax app on an iPhone After choosing a category, players are given 10 multiple choice questions. After each question, players are told if they answered correctly and are provided with a bit of additional information. At the end of the round, players are provided with their scores as well as the average score of all previous players. The game contains more than 250 questions. It can be played on devices ranging from mobile to desktop and can easily be accessed through

While we hope you will try the game, we are most interested in helping you employ it as a useful tool in your vaccine program. Here are some ways to use the game and its content:

  • Refer to information from the game in vaccine discussions.
  • Hold a patient contest using the game or questions from the game.

How did you do? Answers and supplementary information

  1. The correct answer is D. Lewis Carroll wrote many stories but is probably most famous for writing Alice in Wonderland and Through the Looking Glass. Lewis Carroll died from influenza in 1898.
  2. The correct answer is C. A measles outbreak during the 1988-89 basketball season caused Siena College (New York) and the University of Hartford (Connecticut) basketball teams to play five games each without spectators. Interestingly, both teams played better in the absence of fans, scoring more points and attaining higher free-throw percentages.
  3. The correct answer is A. Children born in 1942 received four vaccines that contained more than 3,000 immunologic components. Conversely, children today receive 14 vaccines that contain fewer than 150 immunologic components.
  4. The correct answer is B. Because the chickenpox vaccine contains gelatin, people who are allergic to gelatin should not receive this vaccine.
  5. The correct answer is A. Diphtheria was called “the strangling angel of children” because of the thick membrane that develops in the back of the throat, often covering airways and causing suffocation.
