The Coalition for Epidemic Preparedness Innovations (CEPI) is a global, public–private partnership founded in 2017 to dramatically accelerate the development of vaccines against emerging and pandemic-threat pathogens—and ensure they’re made available to everyone in need. Headquartered in Oslo and with wider offices in London and Washington, D.C., CEPI works across sectors and continents to fund cutting-edge vaccine R&D, convene international partners, and drive innovations like its bold “100 Days Mission”—aiming to shrink response times so a new vaccine could reach mass production within just three months of recognizing a new threat.
