From: Safety and immunogenicity of inactivated Rift Valley Fever Smithburn viral vaccine in sheep
Neutralizing antibody immune response conferred by the inactivated RVFV vaccines in sheep. Neutralizing antibody titres were measured using serum neutralization test for day 0, 7, 14, 21, 28, 35, 42, 49, 56 and 63 post vaccination. The commercial OBP-inactivated RVF vaccine and sterile vaccine diluent were respectively included as positive and negative controls. Error bars represent standard error of the mean (SEM)
