🩺 VaxTrack - Child Vaccination Reminder System

A smart, automated vaccination tracking system designed to ensure every child gets their vaccines on time.

🌟 Overview

VaxTrack is a simple yet powerful web application designed to help parents track their child's vaccination schedule. Using a clean, glassmorphism-inspired interface, parents can register their child and receive automated email reminders when vaccines are due.

This project simulates a minute-by-minute demo of a child's growth to showcase the reminder system in real-time presentations.
