Who could benefit from this research

Could help

Low-income Latinos, especially those with limited English proficiency, who are unvaccinated or hesitant about COVID-19 vaccines.

Less likely to help

Individuals outside LEP Latino communities or those without vaccine hesitancy may see limited direct benefit.

What this research studies

The project partners with Latino communities in Maryland to test a combined social-network and mobile health strategy led by community health workers. They will recruit 300 index participants who already got the vaccine and train half of them to become peer mentors to encourage their networks, using in-person outreach and text messaging. They will also enroll unvaccinated network members, aiming for about 1,590 participants total, and follow everyone for up to 18 months to see how uptake changes. The goal is to identify effective ways to reduce vaccine hesitancy and improve access within LEP Latino communities using real-world outreach.

Why it matters

Potential benefit: If successful, the approach could increase COVID-19 vaccination rates and reduce health disparities in Latino communities.

How similar studies have gone: Prior community health worker and network-based strategies have shown promise in improving vaccination uptake in similar populations, but results vary by context.
