New research finds persistent stockouts and exposure to freezing are among problems in vaccine supply chains designed during an era with fewer childhood immunizations.

Outdated vaccine supply and distribution systems are delaying and limiting the impact that vaccines have on safeguarding people’s health, according to the editors of a collection of new articles published in Vaccine. Among the challenges of ensuring a consistent supply of potent vaccines identified by researchers: one in every three countries in the world experiences at least one stockout of at least one vaccine for at least one month; and 19 to 38 percent of vaccines worldwide are accidentally exposed to freezing temperatures, potentially compromising the potency of those vaccines.

Some countries are implementing changes and adopting new technologies like solar “direct drive” refrigerators and redesigning delivery systems. These changes are helping increase vaccine availability and coverage, even in more remote areas, according to the editors.

The 29 articles are part of a special supplement to Vaccine coordinated by the global health nonprofit, PATH—with guest editors from the Bill & Melinda Gates Foundation, UNICEF, and the Johns Hopkins Bloomberg School of Public Health—that identify challenges and point to solutions that countries can employ to modernize their...
