Fig. 3From: Safety and immunogenicity of inactivated Rift Valley Fever Smithburn viral vaccine in sheepValidation of the inactivation of rift valley fever virus (RVFV) Smithburn using real time cell analysis (RTCA) assay. Growth profile of Vero cells infected with the inactivated and live RVFV Smithburn was recorded. No cell death was recorded in Vero cell culture infected with the inactivated RVFV Smithburn as indicated by the stationary cell index following treatment. The live RVFV induced a decline in cell index showing cell death following treatment with the virus. Vero cell culture was included as positive controlBack to article page
