Experts claim Ebola vaccine breakthrough may herald end of disease
The serum was 100 per cent effective, after a week, in more than 7,600 people inoculated.
An Ebola test vaccine provided blanket protection in a field trial in Guinea, said researchers yesterday, possibly heralding "the beginning of the end" for the devastating West African outbreak that has killed thousands.
The serum was 100 per cent effective, after a week, in more than 7,600 people inoculated, according to results published in The Lancet and hailed as "extremely promising" by World Health Organisation (WHO) chief Margaret Chan.
The world was "on the verge of an effective Ebola vaccine," the UN's health agency said in a statement.
"The initial results of the study show that the vaccine can effectively contain the further spread of the Ebola virus," said the University of Bern, which contributed to the research.
Though encouraging, the results are "interim" and the vaccine will not become immediately available as a community-wide Ebola shield, experts cautioned.
About 28,000 people have been infected in Guinea, Sierra Leone and Liberia since late 2013, according to the WHO. Nearly half have died, but there is thought to be a large undercount of cases and deaths. Having brought an already fragile health sector to its knees, the outbreak has started winding down but is not over.
