In collaboration with government partners, we executed a major multi-region Head Count Survey across 57 districts (Woredas) in Afar, Amhara, Oromia, and Tigray. This critical effort analyzed over 1 million households and 4.59 million individuals to address a core systemic challenge: inaccurate population data is undermining vaccine delivery and equity.
The Challenge: The Hidden Population Gap
For years, immunization programs relied on population projections that do not reflect Ethiopia’s dynamic demographic reality. This results in significant planning errors:
• Inaccurate Denominators: Our recalibrated population data shows that projected estimates often sharply diverge from the reality on the ground. For example, the proportion of adolescent girls (aged 9–14 years) was consistently underestimated by over 90% in population projections across all Woredas.
• Wastage and Stockouts: Many Woredas overestimate their target populations by 40% to 60%, leading to inflated vaccine needs and wastage. Conversely, underestimation leads to stockouts and missed vaccination opportunities.
• Geographic Barriers: Distance severely restricts access. Households located more than five kilometers from the nearest health facility were significantly more likely to have unvaccinated children and higher dropout rates. In regions like Tigray and Afar, more than one third of households travel over 5 km to reach care.

Our Impact: Data-Driven Equity and Efficiency
The head count report provides the evidence required to transform service delivery, ensuring resources are deployed efficiently to the most vulnerable populations.
1. Pinpointing Vulnerable Communities (Zero-Dose Burden)
Our analysis revealed substantial regional disparities, helping us target the hardest-to-reach groups:
• Afar is the highest-burden region, recording the highest zero-dose prevalence for essential vaccines. Over one-quarter of children aged 12–59 months in Afar have never received the Penta-1 or measles vaccine.
• Access Inequities: Nearly 90% of unvaccinated children live in rural areas. Furthermore, urban households are 5.45 times more likely to vaccinate their infants than rural households.
• Distance is the Key Predictor: Households over 5 km from a health facility had 49% lower odds of vaccinating their infants compared to those nearby.
2. Achieving Efficiency and Reducing Wastage
By aligning planning values with the highly accurate head count data, the immunization program can immediately gain efficiency:
• Accurate Forecasting: Correcting denominator errors improves accuracy in vaccine forecasting and better directs outreach to underserved communities.
• Evidence-Driven Allocation: The data provides a reliable foundation for planning and resource allocation, strengthening the entire immunization system and accelerating progress toward national coverage goals.

Amref Health Africa’s comprehensive report synthesizes multiple indicators—including zero-dose prevalence, dropout rates, facility distance, and denominator errors—into a Composite Zero-Dose Index. This index identifies specific Woredas in need of urgent, targeted interventions.
