Latinx people in the USA have had a high burden of COVID-19 cases, hospitalizations, and death, yet rates of COVID-19 vaccine uptake among Latinx individuals were lower than other demographic groups. Effective strategies to promote vaccine uptake among Latinx communities are needed. We conducted a rapid review of information available between December 2020 and August 2021. Our search strategy used PUBMED, Google, and print media with a prescribed set of definitions and search terms for two reasons: there were limited peer-reviewed studies during early period of roll-out and real-time perspectives were crucially needed. Analyses included expert opinion, descriptions of project implementation and outcomes. We found that approaches varied. An integral component with all interventions was the use of local Latinx community leaders. They could understand the nuances of vaccine hesitancy, access issues, and structural inequities experienced by Latinx communities. The mechanisms for messaging included the use of social media, radio, and promotora outreach workers to disseminate information about COVID-19 vaccines and counter misinformation. Phone hotlines for scheduling were reported. Promoting access involved pop-up clinics at shopping malls, farmer’s markets, and nearby grocery stores which were popularly used to vaccinate Latinx community members. Other practices included limited registration requirements, avoiding online-only communication, and training staff to provide specialized support to Latinx clients. This rapid review provides a basis for developing strategic implementation to increase COVID-19 vaccine uptake in this ongoing pandemic and planning to promote health equity for future bio-events and health crises.
