Conditions
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
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
Push notifications at two time points: * two weeks prior to the immunization due date * one week after the immunization due date
