The World Health Organization has approved the distribution of unproven drugs to help address the Ebola outbreak in West Africa. WHO Assistant Director-General Marie-Paule Kieny said the decision was made despite tests that failed to prove the drugs are safe and effective.

Marie-Paule Kieny: “None have undergone the test in humans necessary for licensing as proven safe and effective treatments. That does not mean that they are not safe. It simply means we do not have the evidence from human studies to say that it is certain that they are safe and efficacious.”
