Since the COVID-19 pandemic began, vaccination rates for preventable diseases, including influenza, have significantly dropped among racially and ethnically minoritized (REM) individuals in the United States. This study explored the effects of a community-based educational intervention designed to improve influenza vaccine literacy and acceptance among vulnerable REM individuals. The intervention included four 45 min interactive educational sessions on the influenza vaccine. The session attendees (18+) were invited to participate in a pre-/post-intervention study where an anonymous survey measured their post-COVID-19 pandemic attitudes, knowledge, and behaviors regarding the influenza virus and vaccine. To assess the effect of the intervention on vaccine literacy, we used a Mann-Whitney U test to test for differences between the pre-/post-intervention survey responses to seven knowledge-based questions. Descriptive statistics were employed to assess the impact of intervention on vaccine acceptance. A total of 116 participants completed the pre-intervention survey, and 90 (78%) completed the post-intervention survey. All (100%) identified as REM, and 99% lived in highly vulnerable areas. Only 43% believed they were at risk for viral infection before the intervention, but 60% said the intervention helped them reassess their risk. We found significant differences in vaccine literacy when comparing the pre-/post-intervention survey responses, particularly regarding guideline-based vaccine recommendations (p < 0.05). Before the intervention, 65% of the participants indicated a high likelihood of receiving the influenza vaccine. In contrast, after the intervention, 81% of respondents indicated a high likelihood of being vaccinated, and 72% indicated that they were "extremely likely" to receive the immunization. Community-based educational interventions can have a positive impact on influenza vaccine literacy and acceptance among vulnerable REM populations in the post-COVID-19 era.
