YEREVAN, AUGUST 1, ARMENPRESS. A paper published today in the British medical journal Lancet reports that the vaccine, which has been tested in Guinea since March 2015, has shown extraordinary results so far, with 4,123 people voluntarily vaccinated and all safe from the disease. As reports Armenpress citing Popular Science, the joint study-conducted by international teams from the World Health Organization, the Guinean Health Ministry, Doctors Without Borders, the Norwegian Institute of Public Health and the nonprofit Epicentre research center, among many others-has been 100 percent effective in vaccinated individuals.

“This is an extremely promising development,” said Dr. Margaret Chan, the Director General of the World Health Organization (WHO), in a statement issued earlier today. However, she and the reviewers of the study are keen to point out that these are preliminary results, and advise the trial to continue.
