CHAI works to save lives and immunize as many children as possible by creating dramatic and sustainable improvements to vaccine markets and national immunization programs. Globally, we negotiate prices with manufacturers to make vaccines and the temperature-controlled supply chains needed to deliver them, more affordable. We directly support 11 countries in Africa and Asia to improve uptake of and access to existing, underused and new vaccines. We focus on better service delivery, logistics management systems, and support for countries transitioning from donor funding in order to sustain the gains already made in immunization coverage over the long-term. Alongside our partners, including the Bill & Melinda Gates Foundation, the United Kingdom’s Department for International Development (DFID), Gavi, the Vaccine Alliance, the ELMA Vaccines & Immunization Foundation, World Health Organization (WHO), and UNICEF, our work benefits 128 million children born every year.
