Immunization supply chains: Why they matter and how they are changing

Members of Gavi, the Vaccine Alliance, have articulated the complex, interdependencies inherent to supply chain systems and identified five fundamental areas that must be improved as we develop the next-generation of immunization supply chains: leadership, oversight, design, data, and cold chain equipment. Interestingly, while these five fundamental areas all focus on country-level processes, each area can be impacted by decisions made in the earliest discovery phases of vaccine development, all the way to the implementation phases of vaccine deployment.
