Even though complete protection was not achieved by genetic immunisation, four out of eight mice vaccinated with cDNA encoding the nucleocapsid protein displayed no clinical signs of infection after challenge. In contrast, all fourteen control animals displayed clinical manifestations of Rift Valley Fever after challenge [PubMed: 19149901]. Allen Xiang
