From: Safety and immunogenicity of inactivated Rift Valley Fever Smithburn viral vaccine in sheep
Total IgM antibody levels conferred by the inactivated Rift Valley Fever virus (RVFV) vaccines in sheep. IgM 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
