A Tale of 2 Countries: Implementation of the Cold Chain Equipment Optimization Platform in Guinea and Kenya


In 2016, the Gavi Cold Chain Equipment Optimization Platform (CCEOP) was launched to address the crucial need for functional cold chain equipment (CCE) in vaccine supply chains. This platform aimed to enhance immunization equity and coverage goals set by Gavi, the global vaccine alliance. With an investment of US$250 million between 2016 and 2021, Gavi aimed to upgrade and expand cold chain equipment in over 63,000 healthcare facilities around the world.

Two case studies from Guinea and Kenya offer insights into country-specific implementations of CCEOP and provide valuable lessons on leadership, technical capacity, sustainability, and more. The Importance of Cold Chain Equipment Cold chain equipment plays a critical role in maintaining the efficacy of vaccines. It ensures that vaccines are stored and transported within the required temperature range, thereby preserving their potency. Without functional CCE, vaccines can lose their effectiveness, jeopardizing immunization efforts and the health of vulnerable populations. Guinea: Implementing CCEOP with Leadership and Technical Capacity Guinea, a West African country with a challenging health system, successfully implemented CCEOP with a strong emphasis on leadership and technical capacity.

The country recognized the need for a well-coordinated approach to ensure the success of the program. With the support of Gavi, Guinea focused on enhancing the skills and knowledge of healthcare workers involved in the immunization supply chain. The implementation involved training healthcare staff on the proper use and maintenance of cold chain equipment. This investment in capacity building enabled Guinea to achieve a high level of ownership and sustainability of the cold chain system. By empowering local leaders and technicians, Guinea’s CCEOP implementation became a success story, showcasing the importance of strong leadership and technical expertise for program effectiveness. Kenya: Prioritizing Investments and Ensuring Sustainability Kenya, an East African country with a robust healthcare system, prioritized investments and sustainability during its CCEOP implementation. The country recognized the need to optimize its existing cold chain infrastructure. With Gavi’s support, Kenya focused on upgrading and expanding its CCE footprint to ensure a more efficient and reliable vaccine supply chain. Kenya strategically directed its investments to areas of greatest need, considering factors such as population density and accessibility. This approach ensured that healthcare facilities in remote and underserved regions received the necessary support.

Additionally, Kenya emphasized the development of maintenance and repair systems to uphold the sustainability of the cold chain equipment. Lessons for Other Countries The experiences of Guinea and Kenya hold valuable lessons for other countries embarking on large-scale health system interventions, particularly those related to supply chain strengthening and immunization programs.

1. Leadership and Country Ownership Strong leadership and country ownership are crucial for the success of any health system intervention. Guinea’s emphasis on empowering local leaders and Kenya’s strategic approach to investments both demonstrate the importance of leadership in driving change and ensuring sustainability.

2. Technical Capacity and Training Investing in the technical capacity of healthcare workers is essential for the effective implementation of CCEOP. Guinea’s focus on training healthcare staff and Kenya’s emphasis on developing maintenance and repair systems highlight the significance of technical expertise.

3. Sustainable Supply Chain Systems To ensure the long-term sustainability of cold chain equipment, countries must prioritize the development of maintenance and repair systems. Kenya’s emphasis on sustainability through infrastructure optimization serves as a valuable example for other countries.


The implementation of the Gavi Cold Chain Equipment Optimization Platform in Guinea and Kenya offers important insights into how countries can prioritize investments and implement large-scale health system interventions. By focusing on leadership, technical capacity, ownership, and sustainability, these two countries have achieved remarkable progress in strengthening their immunization supply chains. The lessons learned from Guinea and Kenya serve as a guiding framework for other nations striving to enhance their health systems and improve immunization programs. Understanding the importance of functional cold chain equipment is essential in ensuring equitable and effective vaccine distribution worldwide.
