Globally, millions of children die from vaccine preventable diseases because they are not fully immunized. In North India, fewer than 50% of children are fully immunized; Emmunify uses communications technology to help vaccinate more infants so they can live longer and healthier, perform better in school, and escape poverty. Emmunify effectively and efficiently tracks the status of each child, reminds clients of where and when vaccines are available, facilitates logistics and supply by aggregating utilization and supply data, and eliminates paper records. It is an innovative low cost, focused portable electronic medical record (EMR) that digitizes and replaces the frequently lost or mutilated paper immunization record. It holds multiple copies of each patient’s vaccination record to ensure the data is not lost – in the cloud-based database and stored on an RFID sticker placed on the family’s mobile phone, an item that is always carried with the patient.
