Disparities in COVID-19 Vaccine Hesitancy among Los Angeles County Adults After Vaccine Authorization.

An equitable COVID-19 vaccine rollout is a necessary piece of the public health strategy to end the current pandemic; however, vaccine hesitancy may present a major hurdle. This study examines racial/ethnic and income-based disparities in vaccine hesitancy in Los Angeles County, a recent epicenter of the pandemic in the US, immediately after the Food and Drug Administration issued its emergency use authorization of a COVID-19 vaccine. We conducted online, stratified cross-sectional surveys of 1,984 adults living in Los Angeles County between December 2020 and January 2021 to assess hesitancy towards getting a COVID-19 vaccine. We used multivariable logistic regression to predict vaccine hesitancy after adjusting for covariates and calculated weighted population level estimates of hesitancy and reasons for hesitancy. Blacks and Hispanics were significantly more likely to be hesitant than Whites (AOR=3.3, P $100,000) (AOR=1.8, P=0.009). Additionally, those having no confidence in doing things online (AOR=3.3, P<0.001) were less likely to accept the vaccine than those who were confident. Compared to hesitant White respondents, Black respondents had higher mistrust of the government (36.1% vs 22.1%, P=0.03) and Black and Hispanic respondents were more likely to want to wait to see how the vaccine works (41.2% and 42.0% vs 27.3%, P=0.02 and P=0.006). Our study suggests that culturally appropriate messaging that addresses concerns for lower income and racial/ethnic minority communities, as well as alternatives to online vaccine appointments, are necessary for improving vaccine rollout.
