About this study

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 suggesting the same day of the week, at the same time of day, and at the same pharmacy location as their last vaccination and a control message telling patients that an updated COVID booster vaccine is waiting for them. The intervention testing if text messages encouraging vaccination by suggesting patients receive a shot on the same day of the week, at the same time of day, and at the same pharmacy location as their last vaccination will produce more vaccinations than otherwise identical messages.

Questions about this trial

What is this clinical trial studying?

A study testing COVID Booster text messages in people with COVID-19, run by University of Pennsylvania at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

COVID bivalent booster receipt (time frame: During the 30 days after receiving the SMS/MMS intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2023.
