Ebola: New trial launched in West Africa to evaluate three vaccination strategies

The French National Institute of Health and Medical Research (Inserm), the US National Institutes of Health (NIH) and the London School of Hygiene & Tropical Medicine (LSHTM), in collaboration with health authorities in Guinea and Liberia, are launching a large clinical trial of candidate Ebola vaccines under the aegis of the PREVAC international consortium (Partnership for Research on Ebola VACcination). This trial seeks to identify vaccination regimens that hold the most promise to protect people from Ebola virus disease in order to prevent or quickly control a future outbreak. More than 5,000 adults and children living in countries at the epicenter of the 2014-16 West Africa Ebola epidemic will be enrolled. An additional site in Sierra Leone is also being planned. The PREVAC trial results from a research partnership that involves Inserm, NIH, LSHTM, and the West African Clinical Research Consortium . The pharmaceutical companies Janssen Vaccines & Prevention B.V., part of the Janssen Pharmaceutical Companies of Johnson & Johnson, Bavarian Nordic and Merck Sharp & Dohme, Corp (MSD outside USA and Canada), are supplying the experimental vaccines being tested in the PREVAC trial. The trial will compare three experimental Ebola vaccination strategies with placebo regimens.
