The Advisory Committee on Variola Virus Research was convened in 1999 to implement WHA Resolution (WHA52.10). The Advisory Committee is composed of members from all WHO regions and advised by scientific academic experts from areas such as public health, fundamental applied research and regulatory agencies to oversee:
- all research using live variola virus
- biosafety and biosecurity inspections of the 2 repository sites
- sequencing the viral genome from variola virus isolates
- distribution of live variola virus DNA to other researchers under specific rules.
The Advisory Committee meeting reports are submitted to the World Health Assembly annually and are available online here.
The Advisory Committee has by consensus advised WHO that variola virus should be retained safely and securely to continue the research agenda and advance further public health benefit for smallpox preparedness and mpox prevention and response. The Seventy-seventh World Health Assembly (2024) endorsed the continuing retention of variola virus for this purpose. A review by the Health Assembly is planned for 2029 or sooner as needed.
