Understanding Factors Influencing COVID-19 Testing and Vaccination in Immigrant Low-Income and Homeless Populations and Testing Targeted Interventions

Working with our community partners, we will create and evaluate the impact of a public health intervention in the area of Cumberland County, Maine, to provide outreach, testing, and vaccination education to a large community of immigrants from sub-Saharan Africa, the Middle East, and Central America, higher-risk low-income people accessing a public health facility (with a sexually transmitted infections clinic, needle exchange, and a free clinic), and individuals experiencing homelessness. This will include a longitudinal study to understand beliefs about and knowledge of COVID-19, and barriers and beliefs about testing and vaccination. Results will inform a community-developed and based intervention to engage the cohort and other members of these populations in testing and vaccine education, and evaluate the impact of this intervention on testing and vaccination uptake in our immigrant, low-income, and homeless communities. The Specific Aims are: Aim 1. To understand patient perceptions of, fears about, and experiences with COVID-19 testing in our immigrant, low-income, and homeless populations. Aim 2a. To use the data from Aim 1 to develop and pilot test public health messaging in our immigrant, low-income, and homeless populations, and to develop a strategy for a testing program. Aim 2b. To use the data from Aims 1 and 2a to develop, pilot test, and implement a walk-up, COVID-19 testing program to increase testing uptake in our immigrant, low-income, and homeless populations.
Aim 3. To evaluate the impact of a public health messaging and testing program developed in Aim 2b on rapid COVID-19 testing uptake.
