 In recent years, FAV-Afrique produced by Sanofi-Pasteur was the treatment of reference for venomous snake bites in West and Central Africa. It was the most evaluated and the most effective, reducing by a factor 5 to 10 the mortality. This anti-venom serum was polyspecific, containing an antivenom against ten species of snakes: Naja melanoleuca, nigricollis haje; Dendroaspis polylepis, viridis jamesoni, Bitis gabonica arietans; Echis leucogaster ocellatus.
