New Ebola vaccine offers 100% protection


The 2014 Ebola epidemic cost the lives of more than 11 000 West Africans. Researchers now have developed a vaccine that they consider to offer 100% protection against the disease.  A trial involving nearly 12 000 people was conducted by the WHO and partners in Guinea. No Ebola cases were recorded 10 days or more after vaccination of nearly 6 000 people who received the new vaccine, called rVSV-ZEBOV. “Ebola left a devastating legacy in our country. We are proud that we have been able to contribute to developing a vaccine that will prevent other nations from enduring what we endured," said Dr Sakoba Keïta, co-ordinator of the Ebola Response and the director of the National Agency for Health Security in Guinea. While the new vaccine is still waiting for official approval, some 300 000 doses have already been ordered to prevent any further outbreaks in the region.
