APHA Public Health Policy, Communication & Vaccine Hesitancy 2 — Questions and Answers
Question 1: Which federal agency is primarily responsible for recommending vaccine schedules in the United States?
- FDA
- CDC (Correct answer)
- NIH
- HRSA
Correct answer: CDC
The CDC's Advisory Committee on Immunization Practices (ACIP) develops and publishes the recommended immunization schedules for the U.S.
Question 2: A parent expresses concern that their child received 'too many vaccines at once.' What is the most evidence-based response?
- Agree to space out vaccines to accommodate parental concerns
- Explain that the immune system can safely handle multiple vaccines simultaneously (Correct answer)
- Offer single-antigen vaccines exclusively
- Defer the decision to a specialist
Correct answer: Explain that the immune system can safely handle multiple vaccines simultaneously
Research shows that infants' immune systems can safely respond to multiple vaccines at once, and combination schedules are designed to optimize protection.
Question 3: The Health Belief Model suggests vaccine hesitancy is most likely when an individual perceives:
- High susceptibility to the disease and high vaccine efficacy
- Low disease severity and high perceived barriers to vaccination (Correct answer)
- High social norms favoring vaccination
- Strong cues to action from healthcare providers
Correct answer: Low disease severity and high perceived barriers to vaccination
The Health Belief Model predicts that low perceived susceptibility/severity combined with high perceived barriers reduces the likelihood of health behavior, including vaccination.
Question 4: Which of the following is a key principle of motivational interviewing when applied to vaccine hesitancy?
- Directly confront and correct all misinformation immediately
- Explore and resolve ambivalence by eliciting the patient's own reasons for change (Correct answer)
- Provide extensive educational pamphlets to overwhelm doubt
- Avoid discussing vaccine risks entirely
Correct answer: Explore and resolve ambivalence by eliciting the patient's own reasons for change
Motivational interviewing focuses on eliciting intrinsic motivation by exploring the individual's own values and reasons rather than using persuasion or confrontation.
Question 5: The National Childhood Vaccine Injury Act of 1986 primarily established:
- Mandatory vaccination requirements for all U.S. children
- A no-fault compensation program for vaccine-related injuries (Correct answer)
- Federal funding for vaccine research and development
- Criminal penalties for vaccine refusal
Correct answer: A no-fault compensation program for vaccine-related injuries
The 1986 Act created the National Vaccine Injury Compensation Program (VICP), a no-fault alternative to the traditional legal system for vaccine injury claims.
Question 6: Which communication strategy is most effective when a patient states 'I've heard vaccines cause autism'?
- Immediately dismiss the concern as misinformation
- Acknowledge the concern, affirm the scientific consensus, and provide context (Correct answer)
- Avoid the topic to prevent conflict
- Agree the science is still evolving
Correct answer: Acknowledge the concern, affirm the scientific consensus, and provide context
Acknowledging concerns validates the patient while sharing scientific consensus and context is more persuasive than dismissal or avoidance.
Question 7: Herd immunity thresholds differ by disease primarily because of differences in:
- Vaccine storage requirements
- The basic reproduction number (R0) of the pathogen (Correct answer)
- The age of the target population
- The route of vaccine administration
Correct answer: The basic reproduction number (R0) of the pathogen
The herd immunity threshold is mathematically derived from R0; diseases with higher R0 (like measles at 12-18) require higher population immunity levels.
