The need for resilient and adaptable cold chain systems has never been greater. EHA GHM enhances global health supply chains with modern, end-to-end temperature monitoring, safeguarding essential vaccines and medicines from the first mile to the last—all under WHO PQS and UNICEF procurement frameworks.
Enhancing Last-Mile Monitoring
In partnership with Gavi, the Vaccine Alliance, EHA GHM supports vaccine cold chain monitoring worldwide. In 2018, Senegal’s Ministry of Health (MoH) engaged EHA GHM to strengthen its national vaccine supply chain. By deploying wireless sensors inside cold rooms, refrigerators, and cold boxes, MoH personnel and frontline workers now have real-time visibility into cold chain performance, with instant alerts available through an easy-to-use mobile platform.
“We found inefficiencies in vaccine stock and supplies which is why we implemented Parsyl. Users are now able to better protect the cold chain.” -- Dr. Amy Lo Ndyaie, Logistics Coordinator, Ministry of Health, Senegal.
EHA GHM in Action
With data-driven insights, Senegal has taken critical steps to optimize its vaccine supply chain and reduce preventable wastage:5% of refrigerators accounted for 50% of alerts – pinpointing key areas for intervention. Targeted equipment replacement could cut vaccine spoilage due to freezing by 24%, ensuring better immunization outcomes nationwide.
How it works
Smart Monitoring for a Resilient Cold Chain
EHA GHM's advanced cold chain monitoring solution ensures the integrity of vaccines and essential medicines throughout storage and transit.
Real-Time Temperature Monitoring
Smart sensors continuously track temperature conditions in storage facilities, transport vehicles, and last-mile delivery points.
Proactive Alerts & Notifications
WhatsApp and email alerts notify health workers of temperature excursions, enabling rapid intervention to protect vaccines.
Shelf-Life Tracking
The Smart Countdown feature monitors remaining shelf life, including thawed ultra-cold chain (UCC) vaccines, to reduce waste.
Reliable in Low-Connectivity Environments
Data is collected and securely stored, even in remote health posts with low or no connectivity, ensuring uninterrupted visibility.
Data-Driven Insights for System Improvement
EHA GHM helps identify cold chain equipment (CCE) malfunctions, improving Expanded Program on Immunization (EPI) supervision and training for sustainable supply chain management.
Impact in Action
“Our supply chain has improved thanks to Parsyl. We've been able to identify and replace certain cold chain equipment and improve best practices for storing vaccines within their recommended temperature ranges.” - Mor Diama, Vaccination Logistician, Ministry of Health, Senegal.
EHA GHM empowers frontline workers with real-time, actionable insights and end-to-end cold chain visibility through the last mile.
Nationwide Cold Chain Optimization. EHA GHM sensors have been deployed in national-level cold rooms and freezers across Senegal, equipping EPI logistics managers with real-time notifications of temperature excursions.
Measurable Impact.
A reduction in temperature alarms over time demonstrates how data visibility improves cold chain management and reduces vaccine wastage.
Expanding Coverage for Immunization Programs
EHA Parsyl is on track to cover 100% of Senegal’s vaccine cold chain and is already monitoring vaccines across multiple African countries.With comprehensive real-time data and actionable insights, governments and health organizations can strengthen supply chains and ensure all people receive safe, effective vaccines.
Parsyl devices have been placed in national-level cold rooms and freezers across Senegal, notifying EPI logistics managers of temperature excursions. The decrease in temperature alarms over time has shown that data visibility has the power to positively impact cold chain management.
Parsyl will soon cover 100% of the country’s cold chain and is already monitoring COVAX vaccines in Senegal and several other African countries.With this kind of coverage and data, countries will be better equipped to make the improvements necessary to ensure all people receive safe and potent vaccines.
