Regional analysis of measles vaccination coverage gaps and zero-dose children across Somalia 2019-2023 | Python | WHO Target Analysis
# 💉 Somalia Measles Vaccination Coverage Analysis — 2019–2023
> **Regional analysis of measles vaccination coverage gaps, zero-dose children, and structural determinants of immunization failure across seven Somali regions — 2019 to 2023.**
---
## 📋 Overview
This project investigates why measles vaccination coverage in Somalia remains critically below the WHO 95% herd immunity threshold — and which structural factors drive coverage failure. The analysis uses district-level immunization data to identify priority regions, quantify unvaccinated child burden, and model determinants of low coverage.

## 🔑 Key Findings
| Metric | Value |
|--------|-------|
| Unvaccinated Children (2023) | **125,025** |
| Regions reaching WHO 95% target | **0 out of 7** |
| Lowest MCV1 coverage | **Southwest State — 46%** |
| Highest MCV1 coverage | **Somaliland — 83%** |
| IDP–coverage correlation | **r = −0.939** (p<0.001) |
| Conflict–coverage correlation | **r = −0.928** (p<0.001) |
