Brief Summary
The COVID-19 pandemic has caused significant morbidity and mortality across the world. Effective vaccines are now available but underutilized. In July 2021, Ascension Health implemented a mandate requiring all employees to obtain the COVID-19 vaccine by November 12th. In August 2021, the number of COVID-19 cases in the US increased rapidly, specifically in states with lower vaccination rates, many of which are served by Ascension Health facilities. In this study, we will evaluate a rapidly deployed health system initiative to use text messaging to nudge Ascension employees who have not yet been vaccinated to commit to a date and receive vaccination.
