GSoC 2025: Immunization and Vaccination Schedule in O3 - Final Presentation

Project Details

Project title: Immunization and Vaccination Schedule in O3

Primary mentor: @dkigen

Backup mentor: @grace

Project link: GSOC 2025: Immunization and Vaccination Schedule in O3

Overview

Over the past 12 weeks, I’ve worked on enhancing the Immunization and Vaccination module in the OpenMRS O3 patient chart. This project focused on creating a visual, intuitive system that helps clinicians track immunization schedules, monitor vaccination status, and ensure patients (especially children) receive timely immunizations.

Immunization schedules are critical for preventing infectious diseases. The goal was to make it easier for clinicians to:

  • See the status of what’s been administered
  • Get reminders about what’s due or missing
  • Identify upcoming vaccinations during patient visits
  • Maintain comprehensive vaccination records

Thoughts on GSoC

GSoC 2025 has been an incredible journey of growth, learning, and contribution to global healthcare. Working with the OpenMRS community has taught me the power of open-source collaboration in solving real-world healthcare challenges.

I’m deeply grateful to my mentors @dkigen and @grace for their guidance, patience, and continuous support throughout this project. Special thanks to the entire OpenMRS community for their feedback, code reviews, and encouragement that helped shape this immunization module. And also special mentions to mentors of mentor @ibacher @dkayiwa and through out this Gsoc journey i would like to thank @mherman22 @veronica @fanderson @jayasanka @beryl

This experience has not only improved my technical skills in React, TypeScript, FHIR standards, and healthcare software development, but also reinforced my commitment to contributing to open-source projects that make a real difference in people’s lives.

Looking forward, I’m excited to continue contributing to OpenMRS and helping improve healthcare delivery worldwide through technology.

Great work on the immunization.

Two questions

  1. Can the eleigibility alert be derived from the age of the patient versus the age as per the schedule. Where a prior dose is missed then the user is notified to start with that
  2. Can we link immunization with stock module? Manufacturer, lot number and expiry would therefore be pulled from the stock module. This would also see to it that the vaccines are tracked via the commodity module
