简要总结
This is a prospective, randomized controlled trial that will evaluate the effectiveness of two different targeted outreach interventions aimed at increasing Covid-19 vaccine uptake. Veterans who are eligible for COVID-19 vaccine receipt by priority status (based on institutional guidelines) will be identified. Veterans must be enrolled into Veterans Health Administration (VHA) care and meet age or illness institutional priority guidelines to be eligible. Veterans eligible for enrollment into the trial will be randomized in a 1:1:1 allocation at an individual level, using permuted block randomization (with random block sizes of 3 and 6) to the following interventions:
- Control arm - receives a text message with standard messaging
- Arm 2 - receives a text message with a message framed for scarcity
- Arm 3 - receives a text message with a message framed for improving the social good
