ImmunizeIndia is an Indian non-profit initiative based in Mumbai that provides free vaccination reminders to parents. This initiative was launched by the Indian Academy of Pediatrics (IAP) in March 2014. 

The service is a mobile application that provides customised reminders to parents of children under the age of 5 years. 

The service is free of cost and is based on the IAP vaccination calendar, which includes all the necessary vaccines for a child.

Parents are required to enter the child's name, child's age, address, and phone number. Parents must also select the child's birth date and time, and must add the address of their nearest hospital.
