This project focuses on designing a scalable, automated vaccination reminder system aimed at reducing missed childhood immunization appointments among nursing mothers.
Through user research, I identified that most missed vaccinations are unintentional, driven by forgetfulness and lack of structured reminder systems—not lack of awareness. Additionally, users showed a strong preference for existing communication channels (SMS, WhatsApp, and phone calls) over mobile apps.
Based on these insights, I designed a hospital-side patient engagement system that leverages multi-channel automated reminders, including SMS, WhatsApp messages, and AI-powered outbound voice calls. The system follows predefined communication scripts to ensure consistency, accuracy, and compliance in healthcare messaging.
