The goal of this clinical trial is to find out which approach works better in getting more of the friends and connections of Latino adults get vaccinated against COVID-19.
The main questions this study aims to answer are:
1. Can teaching people to use motivational interviewing help more friends and connections of Latino adults get the COVID-19 vaccine compared to just giving information about the vaccine?
2. What are the things that make it easier or harder for Latinos and networks to get the COVID-19 vaccine?
3. How does this intervention work in practice so that it can be made available to more people in the future
The researchers will compare the vaccine rates of the friends and connections of Latinos who have been trained in motivational interviewing with those who have only been given information about the COVID-19 vaccine. This will help figure out which method works best to encourage more people to get vaccinated.
