Attitudes Toward a Potential SARS-CoV-2 Vaccine: A Survey of U.S. Adults

BACKGROUND: Coronavirus disease 2019 (COVID-19) has rapidly instigated a global pandemic. Vaccine development is proceeding at an unprecedented pace. Once available, it will be important to maximize vaccine uptake and coverage. OBJECTIVE: To assess intent to be vaccinated against COVID-19 among a representative sample of adults in the United States and identify predictors of and reasons for vaccine hesitancy. DESIGN: Cross-sectional survey, fielded from 16 through 20 April 2020. SETTING: Representative sample of adults residing in the United States. PARTICIPANTS: Approximately 1000 adults drawn from the AmeriSpeak probability-based research panel, covering approximately 97% of the U.S. household population. MEASUREMENTS: Intent to be vaccinated against COVID-19 was measured with the question, When a vaccine for the coronavirus becomes available, will you get vaccinated? Response options were yes, no, and not sure. Participants who responded no or not sure were asked to provide a reason. RESULTS: A total of 991 AmeriSpeak panel members responded. Overall, 57.6% of participants (n = 571) intended to be vaccinated, 31.6% (n = 313) were not sure, and 10.8% (n = 107) did not intend to be vaccinated. Factors independently associated with vaccine hesitancy (a response of no or not sure ) included younger age, Black race, lower educational attainment, and not having received the influenza vaccine in the prior year. Reasons for vaccine hesitancy included vaccine-specific concerns, a need for more information, antivaccine attitudes or beliefs, and a lack of trust. LIMITATIONS: Participants\u27 intent to be vaccinated was explored before a vaccine was available and when the pandemic was affecting a narrower swath of the United States. Questions about specific information or factors that might increase vaccination acceptance were not included. The survey response rate was 16.1%. CONCLUSION: This national survey, conducted during the coronavirus pandemic, revealed that approximately 3 in 10 adults were not sure they would accept vaccination and 1 in 10 did not intend to be vaccinated against COVID-19. Targeted and multipronged efforts will be needed to increase acceptance of a COVID-19 vaccine when one becomes available. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality
