After the outcome of the delivery of the registered pregnant women, the system will receive the birth notification as mentioned in the birth notification process. Mothers/caregivers of the newborn will receive auto voice/text messages one day prior to their visit to the vaccination centres. A second reminder will be sent to the parents of all the targeted children through their own phones or their family's numbers collected earlier on the vaccination day at the beginning of the vaccination session for bringing their children for vaccination. A third reminder will be sent to the mothers/caregivers of the children who were not vaccinated after receiving the second reminder as scheduled on that day. The system will also provide auto reminder to the concerned service provider including EPI session wise list of targeted children. The service providers will update the status of vaccination of session using their Smartphone and the system will allow the service providers to see the drop-out and left out cases.
