Figure 3: Viremia in vaccinated and mock-vaccinated sheep following virulent RVFV challenge.

(A) Shows mean QRTPCR Ct values for vaccinated and mock-vaccinated groups. (B) Shows quantitation of viremia by plaque assay. Dash line (---) denotes cut-off point. NPā=āno plaque was isolated. Blanks on the graph (from 5 to 7ādpc) depict no virus was isolated from sheep in either group, vaccinated or mock-vaccinated, by plaque assay.
