Vladimir Putin has shocked health officials across the world by declaring Russian scientists have developed an Ebola vaccine “more effective and stronger” than other drugs currently used. “We have good news. We have registered a medicine for the Ebola fever, which after the relevant tests, has proven to have a high effectiveness, higher than those drugs which until now have been used in the world,” Putin told officials in a government meeting, according to local reports. The Russian president’s claims were received with considerable skepticism by health experts across the globe, reports express.co.uk. The Ebola outbreak - which saw the deaths of 11,000 people in West Africa - sparked a vaccine race. At present, there is one Ebola vaccine demonstrating a very high success rate in clinical trials with the US company Merck. Despite this, the World Health Organization does not currently recognize any Ebola vaccine or treatment.
