Immunization Coverage, Pneumococcal Vaccines
Conditions
Keywords
Vaccine coverage, Vaccine uptake
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.
Interventions
OTHEREnhanced reminders
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
OTHERStandard CANImmunize notifications
Push notifications at two time points: * two weeks prior to the immunization due date * one week after the immunization due date
