Assessing Determinants of COVID-19 Vaccine Hesitancy in Nevada

In December 2020, we conducted a telephone survey to determine what factors are connected to COVID-19 vaccine hesitancy among adults in Nevada. The survey was based on factors identified in other studies, such as demographic variables (age, race, ethnicity, gender, household income, urbanicity, educational attainment), health status, previous COVID-19 infections, social media engagement, adherence to social distancing guidelines, beliefs about COVID-19, and political ideology identifications. Using a proportional odds model, we compared vaccine hesitancy levels to determine the odds of being more likely versus unlikely to get the COVID-19 vaccine. Of 1,000 people surveyed, 30.4% exhibited vaccine hesitancy. Findings showed that adults with significantly lower odds of vaccine hesitancy included those who were male, older, worried about COVID-19 infection or its community effects, adhered to social distancing, and reported higher incomes. Adults who identified as African American or Black or as multiple or "other" races exhibited significantly higher odds of vaccine hesitancy than White adults. Adults self-identifying as conservative had significantly higher odds of vaccine hesitancy than others. Vaccine hesitancy levels suggest possible hurdles to addressing the COVID-19 pandemic in a state with high visitor volumes and demographics that resemble the country's future as minority White, highlighting possible lessons for future pandemics. Most measures of COVID-19 worry were not significantly associated with vaccine hesitancy, suggesting that vaccination efforts should focus on other motivators. COVID-19 vaccination efforts should also directly encourage uptake by younger and middle-aged adults who are female, African American, have lower incomes, and identify as conservative.
