Importance Although widespread vaccination will be the most important cornerstone of the public health response to the COVID-19 pandemic, a critical question remains as to how much of the United States population will accept it. Objective Determine: 1) rate of COVID-19 vaccine hesitancy in the United States public, 2) patient characteristics associated with hesitancy, 3) reasons for hesitancy, 4) healthcare sites where vaccine acceptors would prefer to be vaccinated. Design 43-question cross-sectional survey conducted November 17-18, 2020, distributed on Amazon Mechanical Turk, an online labor marketplace where individuals receive a nominal fee (here, $1.80) for anonymously completing tasks. Eligible Participants United States residents 18-88 years of age, excluding healthcare workers. A total 1,756 volunteer respondents completed the survey (median age 38 years, 53% female). Main Outcome Measure Multivariable logistic regression modeled the primary outcome of COVID-19 vaccine hesitancy (defined as non-acceptance or being unsure about acceptance of the COVID-19 vaccine) with respondent characteristics. Results A total 663 respondents (37.8%) were COVID-19 vaccine hesitant (374 [21.3%] non-acceptors and 289 [16.5%] unsure about accepting). Vaccine hesitancy was associated with not receiving influenza vaccination in the past 5 years (odds ratio [OR] 4.07, 95% confidence interval [CI] 3.26-5.07, p<0.01), female gender (OR 2.12, 95%CI 1.70-2.65, p<0.01), Black race (OR 1.54, 95%CI 1.05-2.26, p=0.03), having a high school education or less (OR 1.46, 95%CI 1.03-2.07, p=0.03), and Republican party affiliation (OR 2.41, 95%CI 1.88-3.10, p<0.01). Primary reasons for hesitancy were concerns about side effects, need for more information, and doubts about vaccine efficacy. Preferred sites for vaccination for acceptors were primary doctors offices/clinics, pharmacies, and dedicated vaccination locations. Conclusions In this recent national survey, over one-third of respondents were COVID-19 vaccine hesitant. To increase vaccine acceptance, public health interventions should target vaccine hesitant populations with messaging that addresses their concerns about safety and efficacy.
