Clinical disease of immunized sheep following PPRV challenge. Following the clinical score proposed on (23) with slight modifications (17), the graded clinical observation for the development of disease after PPRV challenge in immunized sheep was represented. Data are presented as average (± SEM) score for different days post-challenge (dpi) for each treatment group as indicated in the legend. Differences were found to be significant (*p < 0.05; **p < 0.005; ***p < 0.0005; ****p < 0.00005; two-way ANOVA) between control (PBS or BoHV-4-A-ΔTK) and vaccinated group from days 3 to 8 post-challenge.
