Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This experiment is part of a megastudy with a total of ten experimental conditions and a holdout control condition to which patients will be randomly assigned. The focal comparison in this experiment is between a message encouraging vaccination that comes from a patient's local pharmacy team and a control message telling patients that an updated COVID booster vaccine is waiting for them. The intervention testing if text messages encouraging vaccination that come from a patient's local pharmacy team will produce more vaccinations than otherwise identical messages.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomly assigned to the different arms.

Primary Study Purpose

Blinding Strategy

DOUBLE

Caregivers Outcome Assessors

As treated participants will receive text messages, there is no scope for blinding. Care providers will not be made aware of subjects' participation in the study, or assigned treatment arms. The study team will only receive data on subjects' assigned arms and outcomes at the end of the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control condition with "waiting for you" message

This control condition will use the text message that the investigators found to be the best performing in their last mega-study of vaccine text messages to recommend a COVID vaccination.

Group Type EXPERIMENTAL

COVID Booster text messages

Intervention Type BEHAVIORAL

Participants will receive text messages per descriptions listed in the arms
