In Brief

A clinical study evaluating Short Message Service (SMS) + Website Link Strategy and Phone Call with Peer Strategy for Vaccination Refusal and COVID-19. Completed, enrolled 262 participants across 8 sites.

Detailed Summary

The goal of this study is to assess the best COVID-19 vaccine uptake strategy among students, staff and household members that have not been vaccinated. There is a multitude of recommendations present that highlight different vaccination strategy; however, it is still unclear which strategy is best to increase COVID-19 vaccination rates.
