Geneva - The first large-scale trial of an Ebola vaccine will begin in Guinea at the weekend, the World Health Organisation said on Thursday, weeks after a similar test kicked off in neighbouring Liberia.
The Phase III testing of the vaccine -- one of two that are in the most advanced stages of development -- aims to ensure it provides protection against the virus that has killed some 9 800 people in Liberia, Guinea and Sierra Leone.
There is no licensed treatment or vaccine for Ebola, and the WHO has endorsed rushing potential ones through trials in a bid to stem the epidemic.
