Racially minoritized groups are more likely to experience COVID-19 vaccine hesitancy and have lower vaccination rates.  As part of a multi-phase community-engaged project, we developed a train-the-trainer program in response to a needs assessment. “Community vaccine ambassadors” were trained to address COVID-19 vaccine hesitancy. We evaluated the program’s feasibility, acceptability, and impact on participant confidence for COVID-19 vaccination conversations. Of the 33 ambassadors trained, 78.8% completed the initial evaluation; nearly all reported gaining knowledge (96.8%) and reported a high confidence with discussing COVID-19 vaccines (93.5%). At two-week follow-up, all respondents reported having a COVID-19 vaccination conversation with someone in their social network, reaching an estimated 134 people. A program that trains community vaccine ambassadors to deliver accurate information about COVID-19 vaccines may be an effective strategy for addressing vaccine hesitancy in racially minoritized communities.
