This includes communities of color, essential workers, immigrants and migrants, people in rural areas, and people with chronic diseases like diabetes and high blood pressure. We want to train community outreach workers and peer recruiters from community and faith-based organizations to help reach these underserved populations with COVID-19 testing and COVID-19 vaccines - a strategy known as "community-based task shifting."
