Unusual Ebola vaccine study pays off in Guinea
Martin Enserink
On 31 July, The Lancet published the interim results of a clinical trial in Guinea that showed that an Ebola vaccine produced by Merck appears to be highly effective. The study, organized by the World Health Organization in a consortium with many other agencies, used an unprecedented ring vaccination design, in which the contacts of new Ebola cases as well as the contacts of contacts were vaccinated. The outcome was hailed as a landmark by other scientists, who hope that the vaccine can help to finally end the epidemic in Guinea and Sierra Leone, the two countries that still have Ebola cases.
