Delivering vaccines during an Ebola outbreak

Discover how IAVI and our partners collaborated to accelerate the response to Uganda’s sixth outbreak of Sudan virus disease, including the launch of a ring vaccination trial just four days after the outbreak was announced. Sudan virus (SUDV) is an orthoebolavirus that causes a severe and often fatal viral hemorrhagic fever.

We sat down with Swati Gupta, IAVI’s VP and head of emerging infectious diseases and epidemiology, to discuss this blueprint for a successful outbreak response. Watch this IAVI Impact video to learn about the global health security risks posed by SUDV, and how a vaccine is urgently needed to help prevent future outbreaks.
