The World Health Organization (WHO) says there is currently no ready vaccine for the Ebola outbreak affecting the Bundibugyo species in central Africa, and that availability will likely take months. WHO officials report that two potential candidate vaccines are being developed, but neither has yet completed clinical trials. WHO advisor Dr Vasee Moorthy says vaccine timelines could extend up to nine months for this specific Ebola strain. Separately, WHO Director-General Dr Tedros Adhanom Ghebreyesus told a press briefing that the most promising potential vaccine is unlikely to be available for six to nine months. The WHO links the slow progress to the stage of vaccine development rather than immediate deployment. Meanwhile, the outbreak response is described as being hindered by security concerns in affected areas, and the situation continues to worsen as suspected cases rise. One report cites 139 deaths to date and notes that suspected case numbers have grown to around 600. Both accounts emphasize that vaccination is not imminent, while WHO continues to prepare for a future vaccine rollout if candidates prove effective.
