When the COVID-19 vaccine became widely available in spring of 2021, Black and Latinx populations had a slower uptake of the vaccine. While this gap has narrowed over time, new research from DePaul University examines why people in communities of color delayed their vaccinations. The findings may inform more persuasive messages to break down vaccine hesitancy around the COVID-19 booster, flu shot and future vaccines, said lead researcher Joanna Buscemi.
