NCT05419232

Brief 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. We will compare the effectiveness and acceptance of two different communication strategies among unvaccinated students, staff, and their household members.

Outcome Measures

Primary Outcomes (1)

  • Vaccine Uptake

    The primary outcome of this study will be the percentage of individuals who received any COVID-19 vaccination within two weeks of a study intervention. Vaccine uptake will be primarily assessed by verbal confirmation of recent vaccination during a follow-up visit with a study team member.

    Up to 8 weeks

Secondary Outcomes (1)

  • Vaccinated or Indicated They Would Receive Vaccine

    Up to 8 weeks

Study Arms (2)

Short Message Service (SMS) with an associated link to a multi-media website

ACTIVE COMPARATOR

The participant will receive a SMS with a brief message containing the following: (1) statement encouraging them to get vaccinated and (2) a link to a multi-media page with videos and additional resources encouraging individuals to be vaccinated. The multi-media website will be housed in the Safe Return To School website and updated by a designated study team members. This page will include the following COVID-19-related resources: publicly available vaccine promotion videos, videos consisting of community members discussing vaccine topics, resources regarding local vaccine sites, and links to additional literature resources.

Other: Short Message Service (SMS) + Website Link Strategy

Phone Call with Peer

ACTIVE COMPARATOR

The participant's peer will be a study team member who has the same or similar racial demographic as the participant. All team members conducting the peer phone calls will be trained in motivational interviewing. The participant will be called by their peer via zoom or phone. Motivational interviewing techniques will be utilized with the participant to promote vaccine uptake. The team member will use a facilitator guide throughout the peer intervention.

Other: Phone Call with Peer Strategy

Interventions

The intervention we are evaluating is the effectiveness of a participant receiving a SMS + Website Link as a vaccine uptake strategy
