Friends helping friends: new study aims to boost COVID-19 vaccination in latino communities
NCT ID NCT06128928
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two ways to encourage COVID-19 vaccination among Latino adults and their friends in Maryland. One group learns motivational interviewing skills to talk about vaccines, while the other just gets vaccine information. Researchers will compare how many friends get vaccinated in each group to see which method works better.
