Correlates of COVID-19 Vaccine Uptake in Black Adults Residing in Allegheny County, PA.

Introduction: Efforts to address vaccine uptake and access among black adults will be relevant for continued coronavirus disease 2019 (COVID-19) eradication efforts and can be transferable to other prevention efforts in future pandemics. This study investigated factors related to COVID-19 vaccine uptake and access among black residents in Allegheny County, PA.

Methods: Surveys were administered electronically from October 2021 to January 2022 to black Allegheny County residents aged 18 and older. Questions included thoughts on COVID mitigation strategies (e.g., masking, social distancing), vaccination status, intention to vaccinate children, trust of COVID-19 information sources and vaccines, family needs, access to support services, and social media use to access information. Descriptive statistics and significant correlates of being vaccinated using adjusted logistic regression models are reported.

Results: Of the overall sample (=397), the majority were fully vaccinated (=306, 77%). Fully vaccinated participants were more likely to be female (62.5%, =0.010), age 60 years or older (34.3%, =0.0002), have some college education (23.2%, <0.0001), and be employed full time (50.0%, =0.0001) compared with nonvaccinated individuals. Among the unvaccinated participants (=91), the primary reason was fear of illness (8.9%), long-term effects (6.5%), mistrust in the vaccine (6.3%), and needing more information (4.5%). Vaccine-hesitant participants were more likely to be unvaccinated (adjusted odds ratio=2.3, 95% confidence interval 1.25-4.14) after adjusting for age, education, employment, insurance, health status, and income.

Conclusion: Vaccine hesitancy may be improved by directly addressing fear of illness resulting from vaccines and improving clarity in the vaccine development and approval process to improve uptake among black adults.
