The WHO has issued updated emergency guidance on the possible use of Ervebo during the ongoing Ebola outbreak involving the Bundibugyo virus. The guidance, released September 1, addresses how an existing Ebola vaccine could potentially be used even though it was developed for a different Ebola species.
Ervebo is licensed for protection against Zaire ebolavirus, while the current outbreak involves Bundibugyo ebolavirus. The updated guidance focuses on how vaccination could fit into an emergency response where no licensed vaccine specifically targets the circulating strain.
