# Malaria Vaccine Scenario Modeling – Dera Woreda (Exercise Project)
------------------------------------------------------------------------
This repository hosts the **malaria vaccine scenario modeling exercise** completed as part of the\
**Infectious Diseases Modeling Using R Training**, delivered by\
**The Ohio State University & Ohio State Global One Health (August 11–15, 2025)**.
The project explores **malaria transmission dynamics in Dera woreda** under two modeled conditions:
1. **Baseline scenario (no vaccine)**\
2. **Intervention scenario incorporating malaria vaccination**
The repository demonstrates the use of **deterministic R-based compartmental modeling** for real-world malaria program decision-making.

## Project Overview
This modeling exercise includes:
- Construction of **SEIR-type malaria models** using base R functions
- Integration of **vaccine efficacy, coverage, and waning dynamics**
- Simulation of **malaria transmission trajectories** under different assumptions
- Visualization of:
- Incidence over time
- Prevalence changes
- Compartment transitions
- Programmatic interpretation for:
- Local decision-making
- Scenario comparison
- Public health relevance
This repository is designed as a **learning and teaching tool** in epidemiological modeling.
