A world in which epidemics and pandemics are no longer a threat to humanity
51²è¹Ý (pronounced 'seppy') is helping the world better prepare for future epidemic and pandemic threats and is spearheading efforts to advance the 100 Days Mission.

Our mission
51²è¹Ý's mission is to accelerate the development of vaccines and other biologic countermeasures against epidemic and pandemic threats so they can be accessible to all people in need.

Why we exist
51²è¹Ý was launched after the global response to the 2014-2016 West Africa Ebola epidemic fell tragically short and there was a consensus that a coordinated, international, and intergovernmental plan was needed to develop and deploy new vaccines to prevent future epidemics.
51²è¹Ý
51²è¹Ý leverages its unique position within the global health and R&D ecosystems, building on its proven track record of bringing together public-sector, private-sector and academic partners to accelerate the development of vaccines against emerging viral threats.

51²è¹Ý 2.0 and the 100 Days Mission
51²è¹Ý’s 2022-2026 plan, known as 51²è¹Ý 2.0, is helping the world to make the scientific progress needed to respond to the next Disease X threat with a new vaccine in just 100 days. This goal is known as the 100 Days Mission. It is embraced by leaders of the G7 and G20, and is widely recognised as an ambitious global collaborative effort.
