Investing in Vaccine Security: Reducing Loss, Saving Lives.

The Problem

Every year, millions of vaccine doses in low- and middle-income countries are wasted because of cold chain failures. These losses waste scarce resources and leave children unprotected against preventable diseases. This is measured as DALYs (Disability-Adjusted Life Years), a metric that captures both years of life lost and years lived with disability.Preventing vaccine loss directly translates into more children vaccinated, more lives saved, and stronger population immunity.

The Silent Crisis of Vaccine Loss

Vaccine wastage represents a silent crisis in global health, particularly prevalent in low- and middle-income countries. Each year, millions of vital vaccine doses never reach their intended recipients. This  loss is not merely an economic burden; it actively undermines immunization efforts, leaving vulnerable populations exposed to deadly diseases.

Global Vaccine Pipeline

Vaccines are manufactured and enter a complex global distribution network, destined for communities worldwide.

Cold Chain Breakdowns

Fragile storage and transport systems, often due to power or equipment issues, and failure to maintain required temperatures.

Irreversible Dose Wastage

Temperature excursions render vaccines ineffective and unsafe, leading to the disposal of millions of doses annually.
The primary culprit behind this pervasive wastage is often a compromised "cold chain" — the intricate system of storage and transport that keeps vaccines at their precise, recommended temperatures from manufacturing to the point of vaccination. In many regions, this chain is fragile, susceptible to power outages, inadequate refrigeration equipment, and challenging logistical environments.The direct consequences are dire: precious financial resources invested in vaccine procurement are squandered, and the weakened immunity of communities perpetuates cycles of disease. Tackling this systemic issue is crucial for global health equity and achieving universal immunization goals.

The Opportunity

Recent analysis shows that investments in Remote Temperature Monitoring Systems (RTMS) can be as cost-effective as some of the most proven global health interventions.
DALYs Averted by Deployment Model: Median Cost per DALY in USD

The impact is tangible: in Nigeria alone, avoiding 1% of vaccine loss would free 700,000 doses — enough to protect hundreds of thousands of children.^

^Footnote (for the data nerds): Calculation: ~7 million annual births × ~10 vaccine doses per child ≈ 70 million doses procured annually. 1% reduction in loss = 700,000 doses preserved. For single-dose vaccines (e.g., measles), that equals 700,000 children; for 3-dose series (e.g., DTP3), ≈ 230,000 fully immunized children.

The Impact in Nigeria: A Tangible Difference

The scale of vaccine loss in low- and middle-income countries is vast, but so is the potential for impact through targeted interventions. Nigeria serves as a powerful illustration of this opportunity.

Significant Potential

With an annual procurement of approximately
70 million vaccine doses, even a small improvement in cold chain integrity yields significant results.

Preventing just 1% of vaccine loss in Nigeria translates directly into 700,000 doses preserved.

Human Impact

These aren't just numbers; they represent hundreds of thousands of children protected from life-threatening diseases like measles, polio, and pertussis, fostering stronger community health and reducing the burden on healthcare systems. This demonstrates the profound human impact of investing in robust vaccine security measures.

EHA's Response

eHealth Africa (EHA) is leading the way in vaccine security. With the recent acquisition of the Parsyl RTMS solution, we now monitor nearly 9,000 assets across Africa. But our approach goes beyond monitoring—we address the entire immunization value chain:
Acquisition & Supply Chain
Vaccine delivery programs distributing nearly 2 million doses; warehousing through EHA Pharma; outsourced logistics through our Vaccine Direct Delivery (VDD) project.
Management & Data Systems
Advanced platforms like microplanning tools, geospatial settlement mapping, electronic registries (eMID for COVID-19), and Lumis (logistics stock management).
Delivery & Implementation
Cold chain repair and maintenance, direct service delivery through EHA Clinics, and outbreak coordination through 11 national and 39 regional Emergency Operations Centers (EOCs).
Innovation
Field testing and PQS acceleration for immunization assets, ensuring that solutions are adapted to real-world conditions in fragile systems.

Why It Matters

By strengthening vaccine security, EHA ensures that billions of dollars already invested in vaccines are not lost. This creates resilient health systems that can deliver under pressure, safeguard supply chains, and ensure no child is left behind.
Cost-Effectiveness Comparison: Measles RTMS interventions are roughly equivalent to insecticide-treated bed nets (~$100 per DALY averted), long considered the global health gold standard.

Cost-Effectiveness of RTMS

Even with conservative assumptions, RTMS sits in the strong-to-good range of cost-effectiveness benchmarks:

Measles RTMS interventions are roughly equivalent to insecticide-treated bed nets (~$100 per DALY averted), long considered the global health gold standard.

Polio and pertussis RTMS compare to HIV prevention ($300–500 per DALY).
