Official title

Community Developed Technology-Based Messaging to Increase SARS-CoV-2 Vaccine Uptake Among People Who Inject Drugs

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

People who inject drugs (PWID) experience disproportionate risk of being infected with SARS-CoV-2, the virus that causes COVID-19, yet due to stigma, fear of mistreatment, and other factors, PWID are far less likely to be vaccinated compared to other populations. In response, we propose to continue our collaboration with a prominent community based organization serving African American and Latino PWID. Our project will explore baseline hesitancy to vaccinate among PWID, identify barriers to vaccination, and then develop and evaluate messaging designed to increase COVID-19 vaccination among our target population of PWID through a clinical trial.
