Vaccine Trivia: Just the Vax is a fun, interactive trivia game that allows you to test and enhance your knowledge of vaccines — whenever and wherever you like. Not only do you get questions and answers, but also a brief explanation that enables you to learn as you play. You can choose one of the four categories (see below) and are given 10 randomly generated multiple choice questions on that topic. At the end of the round, you’ll get your score as well as the average score of all players.

Game categories include:


This section contains questions related to specific vaccines, such as type, development and history. For example, a sample question from the vaccines section asks:

When is the first dose of Hepatitis B vaccine typically given?

a. Shortly after birth
b. At 15-18 months of age
c. At 1-2 years of age
d. At 4-6 years of age

Supplementary information: The correct answer is A. A baby’s first dose of hepatitis B vaccine is typically given shortly after birth. The second dose is given one to two months after the first dose. The third dose is given between 6 and 18 months of age.

Vaccine safety

This section includes questions and answers about vaccine safety concerns (i.e., autism and chronic disease), vaccine ingredients (i.e., aluminum and thimerosal) and the recommended vaccine schedule. A sample question from the vaccine safety section asks:

Well-controlled, reproducible scientific studies did not find a link between autism and what?

a. MMR vaccine, thimerosal and receiving too many vaccines
b. Genetics
c. Thalidomide
d. Rubella

Supplementary information: The correct answer is A. Well-controlled, scientific studies completed in multiple countries have found no link between the MMR vaccine and autism. Thimerosal and receiving too many vaccines do not cause autism either, as concluded by other well-controlled, reproducible scientific studies.

Vaccine-preventable diseases

The vaccine-preventable diseases (VPD) category asks players questions about the causes and spread of vaccine-preventable diseases. A sample question from the VPD section asks: 

Which two countries have not yet successfully controlled the transmission of polio virus through vaccination?

a. U.K. and India
b. Pakistan and Afghanistan
c. Poland and Ukraine
d. Ireland and Germany

Supplementary information: The correct answer is B. Polio is 99 percent eradicated from the world. However, the last 1 percent has been the hardest to achieve because Pakistan and Afghanistan have not yet successfully controlled transmission of polio virus through vaccination.

Famous people and historical figures

This category includes vaccine-related questions about well-known figures. A sample question from the famous and historical figures section asks: 

Which president contracted smallpox just days before delivering a now famous speech?

a. George Washington
b. Abraham Lincoln
c. Grover Cleveland
d. Thomas Jefferson

Supplementary information: The correct answer is B. Abraham Lincoln became ill with smallpox a few days before delivering the Gettysburg Address. Current research suggests that the severity of Lincoln’s illness was downplayed by his doctor to prevent the public from worrying that their president was dying.
