Disparities in COVID-19 vaccine hesitancy among a diverse community-based sample in Connecticut, United States

Though vaccination is among our strongest tools to prevent COVID-19 infections, its delivery has proven challenging. At a time when COVID-19 cases were rapidly increasing in the Northeast, we examined the role of sociodemographic factors, social determinants of health (SDOH), and health-related beliefs, including conspiracy theories, in influencing COVID-19 vaccine hesitancy among a diverse sample of Connecticut (United States) residents. Between August and December 2020, utilizing community partners and advertisements via social media, we surveyed communities known to be most impacted by COVID-19. We used descriptive analysis and multivariable logistic regression to examine vaccine hesitancy. Among 252 participants, most were female (69.8%) and under the age of 55 (62.7%). Approximately one-third reported household incomes less than $30,000 per year and 23.5% were non-Hispanic Black and 17.5% were Hispanic/Latinx. While 38.9% of participants were vaccine hesitant, non-Hispanic Black and Hispanic/Latinx participants were more vaccine hesitant (adjusted odds ratio [AOR] = 3.62; 95% CI 1.77, 7.40) compared to non-Hispanic Whites/Others. Additional factors associated with vaccine hesitancy after adjustment for socioeconomic status and barriers related to SDOH included low perceived risk of COVID-19 and not receiving COVID-19 information from medical institutions and community health workers (p < 0.05). Race/ethnicity, perceived risk, sources of health information, and conspiracy beliefs played a significant role in vaccine hesitancy among this diverse sample. Interventions to promote vaccination should include trusted messengers and sources of information, while long term efforts should focus on addressing the social conditions that deter confidence in scientific data, vaccine efficacy, and the healthcare system.
