Development of a Dual Recombinant Vaccine To Protect Small Ruminants against Peste-des-Petits-Ruminants Virus and Capripoxvirus Infections

A recombinant capripoxvirus vaccine containing a cDNA of the peste-des-petits-ruminants virus (PPRV) fusion protein gene was constructed. A quick and efficient method was used to select a highly purified recombinant virus clone. A trial showed that a dose of this recombinant as low as 0.1 PFU protected goats against challenge with a virulent PPRV strain.
