摘要：
Described herein are recombinant RVF viruses comprising deletions in one or more viral virulence genes, such as NSs and NSm. The recombinant RVF viruses, generated using a plasmid-based reverse genetics system, can be used as vaccines to prevent infection of RVF virus in livestock and humans. As described herein, the recombinant RVF viruses grow to high titers, provide protective immunity following a single injection and allow for the differentiation between vaccinated animals and animals infected with wild-type RVF virus.
