Primary outcomePrimary: Number of Employees Who Scheduled Vaccination Appointments After 3 Days — 101; 207; 220 Participants — p=<.001
Summary
In this evaluation, two versions of emails will be sent to Geisinger employees who have not been vaccinated against COVID-19. A delayed-contact control group will be emailed after a delay of at least two days. The researchers hypothesize that either of the emails - which use content informed by behavioral nudge theory - will lead to more COVID-19 vaccinations than the delayed-contact control group.
