Strategic Advisory Group of Experts (SAGE) on Immunization
The Strategic Advisory Group of Experts (SAGE) on Immunization was established by the Director-General of the World Health Organization in 1999 to provide guidance on the work of the WHO Immunization Department. The Terms of referenceof the Group were revised during 2007 in view of the development of the Global Immunization Vision and Strategy (GIVS). SAGE is the principal advisory group to WHO for vaccines and immunization. It is charged with advising WHO on overall global policies and strategies, ranging from vaccine and technology, research and development, to delivery of immunization and its linkages with other health interventions. SAGE is concerned not just with childhood vaccines and immunization, but all vaccine-preventable diseases.
