The World Health Organisation (WHO) on Friday said that an experimental Ebola vaccine has been found to be 100 per cent effective against the deadly virus in a major human trial in Guinea, giving doctors a safe and potent weapon against any future outbreak, as per the media reports.
The vaccine is the first to prevent infection from one of the most lethal known pathogens, and the findings add weight to early trial results published last year, said the PTI report.
Last year, the vaccine, called rVSV-ZEBOV, was studied in a trial involving 11,841 people in Guinea, among the 5,837 people who received the vaccine, no Ebola cases were recorded 10 days or more after vaccination, according to the results published in The Lancet journal.
In comparison, there were 23 cases 10 days or more after vaccination among those who did not receive the vaccine.
The trial was led by the WHO, together with Guinea's Ministry of Health and other international partners.
