NCT ID: NCT06000397

Last Updated: 2024-04-09

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: NA
• Total Enrollment: 700 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-11-07
• Study Completion Date: 2024-06-30

Brief Summary

The goal of this clinical trial is to assess the effectiveness of enhanced email reminders in improving vaccine coverage at the 12-month visit in CANImmunize app users. The main questions it aims to answer are:

• Do enhanced email reminders improve coverage of the 12- month dose of the pneumococcal vaccine and the timely completion of its immunization series at the 12-month's visit in CANImmunize app users?
• What are the predictors of predictors of timely completion of the 12-month's series of pneumococcal vaccines in the CANImmunize app users?

Participants will be randomized to either receive enhanced reminder/recall materials via email or the standard CANImmunize notifications. Researchers will compare the enhanced reminder group to the standard notification group to see if there is a difference in vaccine coverage at the 12-month visit.

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: PREVENTION
• Blinding Strategy: NONE

Study Groups

Enhanced reminders

Group Type: EXPERIMENTAL

Enhanced reminders

Intervention Type: OTHER

The intervention is sending enhanced (modality and frequency) of reminders to CANImmunize App users, in addition to the standard notifications. Specifically:

• Deliver reminders and recall emails to parents or guardians of infants waiting for their 12-month dose of pneumococcal vaccine,
• Add additional information about the benefits, safety and effectiveness of the pneumococcal vaccine to support increased uptake, and
• Provide tips to improve parents' or guardians' self-efficacy in circumventing barriers to timely immunization of children at the 12-month's visit

Standard notifications

Group Type: ACTIVE_COMPARATOR

Standard CANImmunize notifications

Intervention Type: OTHER

Push notifications at two time points:

• two weeks prior to the immunization due date
• one week after the immunization due date
