From: Safety and immunogenicity of inactivated Rift Valley Fever Smithburn viral vaccine in sheep
Total IgG antibody levels conferred by the Rift Valley Fever virus (RVFV) formulations in sheep. IgG antibody titres against the RVFV nucleoprotein were measured using ELISA. Serum samples were collected from sheep injected with inactivated RVFV vaccine candidates at 0, 7, 14, 21, 28, 35, 42, 49, 56 and 63 days post vaccination. The commercial OBP-inactivated RVF vaccine and sterile vaccine diluent were respectively included as positive and negative controls. Data sets are presented as the mean ± SEM in the same treatment
