The World Health Organization has added the MVA-BN vaccine to its prequalification list, making it the first vaccine against mpox to receive this approval. This will allow for increased access to the vaccine to help contain outbreaks and reduce transmission. The vaccine, administered in two doses 4 weeks apart, has shown to be effective in protecting against mpox. WHO also recommends single-dose use in outbreak situations with limited supply. Further data on vaccine safety and effectiveness is needed. The ongoing mpox outbreak has led to the declaration of a public health emergency of international concern, with over 103,000 cases reported globally.
