COVID-19 Vaccination Messengers, Communication Channels, and Messages Trusted Among Black Communities in the USA: a Review

Black and African American adults exhibited higher levels of mistrust and vaccine hesitancy and lower levels of vaccination throughout the COVID-19 pandemic. Vaccination and booster uptake remains disproportionately low among Black adults. We conducted a systematic review of empirical research published between February 2021 and July 2022 from five electronic databases and the grey literature. We screened studies that assessed COVID-19 vaccination information needs and preferences as well as communication strategies among Black adults in the USA. We extracted data, then analyzed and synthesized results narratively. Twenty-two articles were included: 2 interventions, 3 experimental surveys, 7 observational surveys, 8 qualitative inquiries, and 2 mixed methods studies. Studies reported credible and preferred COVID-19 vaccination information sources/messengers, channels, and content. Commonly trusted messengers included personal health care providers, social network connections, and church/faith leaders. Electronic outreach (e.g., email, text messages), community events (e.g., forums, canvassing), and social media were popular. Black communities wanted hopeful, fact-based messages that address racism and mistrust; persuasive messages using collective appeals about protecting others may be more influential in changing behavior. Future communication strategies aiming to increase vaccine confidence and encourage COVID-19 booster vaccination among Black communities should be developed in partnership with community leaders and local health care providers to disseminate trauma-informed messages with transparent facts and collective action appeals across multiple in-person and electronic channels.
