Neutralizing SPPV antibody titers after sheep vaccination. The results correspond to the mean antibody titers ± SEM of 16 sheep vaccinated with the inactivated Romanian SPPV vaccine strain (G1) and 4 sheep vaccinated with the live attenuated Romanian SPPV vaccine (G2). (a–b) indicate a significant difference in means antibody titers between animals of G1 and G2 at the 0.05 level
