Given the urgency of the situation, scientists in the Biology of Viral Emerging Infections Unit and the Viral Genomics and Vaccination Unit at the Institut Pasteur evaluated the efficacy of several vaccine candidates. Following their analyses, they identified one of these vaccines, based on the measles platform, as being the most effective to enter clinical testing in humans as soon as possible. This raises hopes in the fight against a disease that claims between 5,000 and 6,000 lives every year. Lassa fever, a hemorrhagic fever caused by the Lassa virus (LASV), is responsible for several thousands of deaths in endemic countries in West Africa every year.
