The approval will significantly improve access to the mpox vaccine, especially in regions facing outbreaks, such as Africa. It is a two-dose vaccine administered four weeks apart for adults aged 18 and older.
WHO Director-General Tedros Adhanom Ghebreyesus emphasized that this approval is a crucial step in combating both current and future mpox outbreaks. He also stressed the need for equitable vaccine distribution, ensuring high-risk populations have access.
Yukiko Nakatani, WHO’s Assistant Director-General, noted that the prequalification would accelerate international procurement and national regulatory approvals.
Current data suggests the MVA-BN vaccine has a 76% efficacy after the first dose and an 82% efficacy after the second dose. WHO reiterated the importance of ongoing data collection on the vaccine's safety and effectiveness.
