This document describes a proposed child immunization system that uses a web and mobile application to track vaccination schedules and send reminders to parents. The system would allow doctors, health workers, and parents to register children and record their vaccination history in a centralized database. Automated reminders would be sent via SMS to parents one day before a scheduled vaccination is due to help increase vaccination rates. The goal is to make the vaccination process more organized and ensure all children receive their vaccines on time through reminders.
