Countries of the Americas strengthen vaccine cold chain with support from PAHO and Canada

Washington, D.C., 16 December 2025 (PAHO/WHO) - In recent months, national immunization programs in 18 countries and territories across the Americas have strengthened their vaccine cold chain systems, ensuring vaccine potency and reinforcing routine immunization. This progress was achieved through technical cooperation from the Pan American Health Organization (PAHO), with financial support from the Government of Canada.

Through PAHO's Regional Revolving Funds, Canada's support provided approximately 1,000 units of cold chain equipment that includes temperature-monitoring devices; long-term, passive cold boxes and vaccine carriers designed for complex logistics and environments; and ice-lined refrigerators with freeze-protection technology.

The 18 participating countries and territories include: Anguilla, Antigua and Barbuda, Bolivia, British Virgin Islands, Cuba, Curacao, Dominica, Grenada, Haiti, Jamaica, Montserrat, Paraguay, Peru, St. Kitts and Nevis, Saint Vincent and the Grenadines, Suriname, Trinidad and Tobago and St. Maarten.

"This new cold chain equipment strengthens the capacity of countries to protect every vaccine dose from the moment it arrives in country to the moment it reaches families and communities," said Santiago Cornejo, Executive Manager of PAHO's Regional Revolving Funds. "These tools help ensure safety, reduce wastage, and expand equitable access to immunization. We are grateful to the Government of Canada for its continued partnership to help us introduce the latest technologies and innovations in the region."

The donation forms part of the PAHO-implemented project that is supported by the Government of Canada, "Improving Equitable Access and Coverage of COVID-19 Vaccination in Latin America and the Caribbean." The initiative aims to reinforce public health systems and infrastructure across the Region.

PAHO's Regional Revolving Funds are technical cooperation mechanisms that enable countries of the Americas to procure quality vaccines, essential medicines, and public health supplies at affordable prices through pooled purchasing and coordinated planning.

By working collectively, countries have saved an estimated 50 percent on vaccines and other health supplies, benefiting around 180 million people in the last biennium. Over the years, the funds have helped countries secure timely access to essential health supplies, supporting progress against HIV/AIDS, malaria, and tuberculosis, while also improving immunization coverage and reducing maternal and child mortality.
