Vaccine Tracker

Inspiration

We were inspired by how easy it is to miss important vaccinations and booster shots, especially when eligibility depends on age, medical history, and timing. We wanted to build a simple tool that reduces confusion for patients and manual work for clinics

What it does

Vaccine Tracker is a lightweight prototype that:

Determines vaccine eligibility based on: Age (DOB) Vaccination history (last dose date) Booster schedules Risk factors (pregnant, immunocompromised) Identifies: Eligible now Due soon Overdue Up-to-date Displays a patient-friendly immunization timeline Simulates reminders (Email, SMS, In-app)

How we built it

Java 17 Maven IntelliJ IDEA

Challenges we ran into

This was our first hackathon, so we ran into challenges at multiple stages of the project. We had limited experience structuring a complete project from scratch, setting up the environment, and integrating different components. Debugging compilation errors and aligning our classes took time, but we worked through these issues together and managed to build a working prototype.

Accomplishments that we're proud of

We’re proud that we were able to design and implement a functional eligibility engine with booster tracking and reminders within the hackathon timeframe. Completing a working end-to-end prototype as a first hackathon team is a big milestone for us.

What we learned

How to structure a small Java project from scratch How to break down a real-world problem into manageable components How to collaborate effectively under time pressure The importance of debugging, testing, and incremental development

What's next for Vaccine Tracker

-Build a web interface for clinics and patients -Add database support to store patient records -Integrate real notification services (email/SMS) -Expand vaccine rules using official immunization schedules -Add CSV upload for bulk patient data
