Information Provision and Consistency Framing to Increase COVID-19 Booster Uptake

Summary

This study investigates different ways to elevate intentions to get the COVID-19 booster via text-based reminders, including providing information about the booster and leveraging the consistency principle. The proposed randomized controlled trial will examine the impact of these reminders on booster uptake.

Conditions

• COVID-19
• Vaccines

Interventions

BEHAVIORAL

Reminder that facilitates action

Patients will receive a text message reminding them that they can now get the bivalent COVID-19 booster and facilitating action. The message will contain a link to schedule a booster appointment at UCLA Health and a link to vaccine.gov (where people can find local pharmacies that carry the bivalent booster).

BEHAVIORAL

Consistency framing

The message will leverage the psychological principle of consistency. It will highlight to patients that based on medical records, they have completed a COVID-19 vaccine primary series, have done a great job protecting their health, and can now get the bivalent booster.

BEHAVIORAL

Information provision about the uniqueness of the bivalent booster

The message will contain information about how the bivalent booster differs from previous doses patients have received and why it is valuable.

BEHAVIORAL

Information provision about bivalent booster eligibility

The message will clarify to patients that regardless of whether they are at high risk, received the original boosters, or previously got COVID-19, they are eligible for the bivalent booster based on their medical records, and the updated booster will be valuable for them.

BEHAVIORAL

Information provision about the severity of COVID-19 symptoms

The message will contain information about the often underestimated chances of people developing severe or long-lasting COVID-19 symptoms. The message will also mention that the bivalent booster can reduce such chances.
