Just the Vax — Vaccine-preventable Diseases

1. In the early 2000s, what two illnesses caused the most deaths of children worldwide?

  1. Meningococcal disease and smallpox
  2. Varicella (Chickenpox) and measles
  3. Pneumonia and severe diarrhea
  4. Influenza and diphtheria

Supplementary information: The correct answer is C. In the early 2000s, pneumonia and severe diarrhea caused the deaths of about 3 million children per year. These numbers are continuing to decrease as vaccines for pneumococcus and rotavirus become more widely available.

2. What vaccine-preventable disease has also been called the 100-day cough?

  1. Pertussis
  2. Pneumococcal disease
  3. Varicella (Chickenpox)
  4. Meningococcal disease

Supplementary information: The correct answer is A. Pertussis, or whooping cough, occurs in three stages with cold-like symptoms occurring during the first stage. Intense and prolonged coughing occurs during the second and third stages, typically lasting for weeks or several months.

3. Some diseases are only found in humans; however, influenza can infect many types of animals. Which animals can also get influenza?

  1. Birds, aquatic birds, pigs, horses, dogs, cats and sea mammals
  2. Bears and deer
  3. Lemurs, lions and tigers
  4. Elephants, zebra, buffalo and meerkats

Supplementary information: The correct answer is A. Besides infecting humans, influenza virus can infect birds, aquatic birds, pigs, horses, dogs, cats and sea mammals. Occasionally, an animal, such as a pig, will be infected with multiple strains that combine to form a new strain that can infect humans. This can lead to a pandemic.

4. What disease could be prevented by a vaccine, but isn’t?

  1. Varicella (Chickenpox)
  2. Lyme disease
  3. Shingles
  4. Hepatitis A

Supplementary information: The correct answer is B. A vaccine for Lyme disease was available from 1998 to 2002. However, because of unfounded safety concerns and lack of use, it was removed from the market. Because a vaccine is no longer available, people can protect themselves by wearing protective clothing and inspecting themselves for ticks after potential exposure.

5. Which vaccine-preventable disease is not affected by herd immunity?

  1. Influenza
  2. Measles
  3. Mumps
  4. Tetanus

Supplementary information: The correct answer is D. Because tetanus does not spread from person to person, people cannot be protected from the disease just because everyone around them has been vaccinated. So, the best way to protect yourself from tetanus is to receive the tetanus vaccine.

6. What disease did parents want their children to share before the vaccine was available?

  1. Polio
  2. Varicella (Chickenpox)
  3. Rotavirus
  4. Haemophilus influenzae type B (Hib)

Supplementary information: The correct answer is B. Before the chickenpox vaccine was available, parents would intentionally expose their children to others with chickenpox so they could become infected and gain immunity during childhood, when the disease is typically less severe.

7. Which disease is known to be more commonly spread from adults to children?

  1. Varicella (Chickenpox)
  2. Pertussis (Whooping Cough)
  3. Measles
  4. Rubella

Supplementary information: The correct answer is B. Typically, children spread infections to adults; however, pertussis (whooping cough) is more commonly spread from adults to children. For this reason, adults who are going to be around young infants are recommended to get one dose of Tdap vaccine. Protecting babies by immunizing those around them is known as cocooning.

8. Which vaccine-preventable disease used to be commonly known as German measles?

  1. Rubella
  2. Measles
  3. Smallpox
  4. Cholera

Supplementary information: The correct answer is A. Rubella is also known as German measles because it was first described in German medical literature as a disease distinct from measles and scarlet fever.

9. Whooping cough is the common name for what vaccine-preventable disease?

  1. Smallpox
  2. Measles
  3. Pertussis
  4. Tetanus

  1. Measles
  2. Diphtheria
  3. Polio
  4. Rotavirus

Supplementary information: The correct answer is A. Measles outbreaks were occurring in Europe due to decreased immunization rates in that region; therefore, travelers to the 2012 London Olympics were warned to be immunized against measles.

13. Which of the following pairs are vaccine-preventable diseases transmitted by mosquitos?

  1. Yellow fever and Japanese encephalitis virus
  2. Measles and Mumps
  3. Varicella (chickenpox) and Lyme disease
  4. Cholera and rubella

Supplementary information: The correct answer is A. Yellow fever and Japanese encephalitis virus are two vaccine-preventable diseases that are transmitted by mosquitos, but vaccines are typically only given to high-risk groups, such as some travelers.

14. The American Red Cross held a campaign to raise funds for distribution of what vaccine?

  1. Polio
  2. Measles
  3. Hepatitis B

Rotary International began the End Polio Now campaign to raise funds to provide polio vaccine to children in areas where infectious polio still exists and to help eradicate polio from the world. Other groups also working in this campaign include the Bill and Melinda Gates Foundation, Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and UNICEF.

16. Lyme disease gets its name from a town in what U.S. state where a cluster of cases occurred in the 1970s?

  1. Connecticut
  2. Arkansas
  3. New Jersey
  4. Florida

Supplementary information: The correct answer is A. In 1975, large numbers of children were diagnosed with rheumatoid arthritis in Lyme, Connecticut. Researchers soon found that most of the children lived in wooded areas and symptoms typically started during the summer. It was not long before scientists determined that Lyme disease was transmitted by tick bites.

17. Botox™ uses a diluted form of the toxin produced by what bacteria?

  1. Corynebacterium diphtheriae
  2. Haemophilus influenzae type B
  3. Clostridium botulinum
  4. Neisseria meningitidis

Supplementary information: The correct answer is C. Botox is a very dilute form of the neurotoxin produced by Clostridium botulinum. Wrinkles are caused by facial muscles that continually contract; Botox treats wrinkles by relaxing these muscles.

18. What vaccine-preventable disease used to be commonly known as “wool sorters disease”?

  1. Anthrax
  2. Yellow Fever
  3. Japanese encephalitis virus
  4. Measles

Supplementary information: The correct answer is A. Anthrax was commonly referred to as “wool sorters disease” because sheep wool was commonly contaminated with Bacillus anthracis, the bacteria that causes anthrax.

19. What vaccine-preventable disease is transmitted from one person to another through contact with an infected person’s blood?

  1. Chickenpox
  2. HPV
  3. Hepatitis B
  4. Influenza

  1. Measles virus
  2. Mumps virus
  3. Influenza virus
  4. Rubella virus

Supplementary information: The correct answer is B. Mumps virus infects the salivary glands in about 35 of 100 people infected with the virus. When these glands begin to swell, the infected person often looks like a chipmunk.

30. What virus can live silently in nerves for years after an initial infection, later awakening due to age or a weakened immune system?

  1. Mumps virus
  2. Rubella Virus
  3. Chickenpox virus
  4. Measles virus

Supplementary information: The correct answer is C. After chickenpox infection, varicella zoster virus lives silently in the nerves. As people age, their immune system weakens, sometimes leading to a reawakening of the zoster virus, causing shingles.

31. Which vaccine-preventable disease can occur when a wound or cut is exposed to soil that contains bacteria?

  1. Pertussis
  2. Tetanus
  3. Meningococcal disease
  4. Pneumococcal disease

Supplementary information: The correct answer is B. Tetanus typically occurs when a wound or cut is exposed to soil that contains Clostridium tetani. Because infection occurs via bacteria introduced in the soil, this disease is not one that people can be protected against by living in a highly vaccinated community.

32. What vaccine-preventable disease is spread by food or water contaminated with the feces of an infected person?

  1. Rubella
  2. Polio
  3. Meningococcal disease

33. What vaccine-preventable disease cannot be spread from one person to another?

  1. HPV
  2. Tetanus
  3. Chickenpox
  4. Measles

Supplementary information: The correct answer is B. Tetanus is the only vaccine-preventable disease that does not spread from person to person. People infected with tetanus are typically exposed when a wound comes in contact with contaminated soil. For this reason, herd immunity, as provided by high vaccination rates, does not apply to this disease.

34. What vaccine-preventable disease can be particularly deadly for the elderly?

  1. Pneumococcal disease
  2. Shingles
  3. Measles
  4. Rotavirus

Supplementary information: The correct answer is A. Pneumococcal disease is known as an opportunistic infection because it usually attacks when a person’s immune system is already weakened by another infection. Pneumococcus is particularly deadly in elderly people when it causes pneumonia during recovery from an influenza infection.

35. What vaccine-preventable diseases are spread through tiny droplets that hang in the air?

  1. Hepatitis B and HPV
  2. Chickenpox and shingles
  3. Measles and chickenpox
  4. Smallpox and pertussis

36. What vaccine-preventable disease was not distinguished from smallpox until the end of the 19th century?

  1. Tetanus
  2. Rubella
  3. Chickenpox
  4. Pertussis

Supplementary information: The correct answer is C. Because chickenpox and smallpox both caused rash-like illnesses, the two diseases were not realized as different until the end of the 19th century.

37. Infection with what virus can cause cirrhosis and liver disease?

  1. HPV
  2. Hepatitis B virus
  3. Measles virus
  4. Mumps virus

Supplementary information: The correct answer is B. People with chronic hepatitis B infection typically suffer severe liver damage, known as cirrhosis, which often results in liver disease or liver cancer. Because most people do not show symptoms of chronic infection, they do not know they are infected until they are diagnosed with liver cancer.

38. What vaccine-preventable disease used to be referred to as “the strangling angel of children”?

  1. Diphtheria
  2. Smallpox
  3. Pertussis
  4. Chickenpox

Supplementary information: 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.

39. What vaccine-preventable disease has a symptom known as “bullneck”?

  1. Mumps
  2. Rubella
  3. Smallpox
  4. Diphtheria

Supplementary information: The correct answer is D. A common symptom of diphtheria is “bullneck,” a condition in which the glands in the neck become swollen, often making the infected person look like they have a bull’s neck.

  2. Chickenpox, shingles and diphtheria
  3. HPV and hepatitis B
  4. Hepatitis A, tetanus and pertussis

Supplementary information: The correct answer is A. Meningitis, or the swelling of the lining of the brain and spinal cord, is a possible complication of infection with Haemophilus influenzae type B, meningococcus and pneumococcus. Symptoms of meningitis can include stiff neck, fever, vomiting, headache, seizures and coma.

43. People without a spleen are more susceptible to which diseases?

  1. Pneumococcal and meningococcal diseases
  2. Chickenpox and measles
  3. Diphtheria and pertussis
  4. Polio and Rotavirus

  1. Yellow fever
  2. Malaria
  3. Diphtheria
  4. Tetanus

Supplementary information: The correct answer is B. The gene mutation that causes sickle cell anemia is an example of adaptation, or the changing of oneself so as to adapt to a changing environment. Sickle cell anemia causes sickle-shaped red blood cells that protect people from malaria because the virus that causes malaria cannot enter red blood cells of this shape.

48. What virus can occur in both humans and chimpanzees?

  1. Polio
  2. Hepatitis B
  3. HPV
  4. Rubella

Supplementary information: The correct answer is A. Besides humans, polio virus can also infect chimpanzees. For this reason, scientists tested the effectiveness of potential polio vaccines in chimpanzees prior to their use in humans.

49. What vaccine-preventable disease kills almost everyone it infects?

  1. Polio
  2. Rubella

50. What vaccine-preventable disease killed almost 90 percent of Aztec, Inca and Maya civilizations?

  1. Rubella
  2. Polio
  3. Smallpox
  4. Diphtheria

Supplementary information: The correct answer is C. The impact of smallpox on Native American populations is a dramatic illustration of how shipping and European colonization of the Americas also caused the transmission of previously unknown vaccine-preventable diseases to susceptible populations.

51. What percent of the world’s population is immunodeficient?

  1. 1 of 100
  2. 10 of 100
  3. 50 of 100
  4. 75 of 100

Supplementary information: The correct answer is A. Immunodeficiency is defined as the inability to generate a normal immune response. In fact, 1 of 100 people are immunodeficient and, therefore, may be unable to receive certain vaccines. For this reason, high vaccination rates are important in providing protection to this group.

52. What company made a system to help track suspected influenza?

  1. Google
  2. Facebook
  3. Apple
  4. Microsoft

Supplementary information: The correct answer is A. Google created Google Flu Trends to learn about influenza interest in the community based on internet searches.

  2. The Stanley Cup
  3. The NBA Finals
  4. Wimbledon

Supplementary information: The correct answer is B. The final game in the 1919 Stanley Cup Finals was cancelled after the coach and multiple players of the Montreal Canadiens were hospitalized with influenza. After both the Canadiens and Seattle Metropolitans won two games and tied the fifth game, the sixth game was supposed to determine the winner of the competition. Because the coach of the Canadiens couldn’t put a full team on the ice for the last game, he forfeited; however, the coach of the Metropolitans refused to accept the forfeit. As a result, no winner was declared for the 1919 Stanley Cup Finals.

54. In Africa, many families do not name their children until the threat of what vaccine-preventable disease has passed?

  1. Rubella
  2. Measles
  3. Pertussis
  4. Polio
