A vaccine that was found after the results from a trial in Guinea shows it to be 100 percent effective against Ebola, the World Health Organization (WHO) said on Friday.
Director-general of the World Health Organization, Margaret Chan spoke in a press conference on Friday regarding the issue.
"The initial results are exciting and very promising," she said.
"If proven effective, this is going to be a game changer, and it will change the management of the current Ebola outbreak and future outbreaks."
The vaccine, known as Merck and NewLink Genetics' VSV-ZEBOV, was tested on over 4,000 people who had been in close contact with a confirmed Ebola patient and according to the results, it gave 100 percent protection on the patients after 10 days.
The results of the vaccine were published online in the medical journal, The Lancet, on Friday where researchers said the vaccine could be "highly efficacious in preventing Ebola virus disease."
According to the WHO, over 11,000 people died from Ebola since the outbreak began in December 2013.
The large majority of Ebola victims are in West Africa including countries such as Sierra Leone, Liberia and Guinea, who have been hit hardest by the outbreak.
