Abstract: |
The aims of this study were to determine and evaluate the safety, duration of immunity and vaccine efficacy of Peste des Petits Ruminants Vaccine (Live, 75/1 Strain), vaccinated in some areas of Xinjiang Uygur Autonomous Region and Tibet Autonomous Region. The Clinical signs of these vaccinated animals were observed for a long time and the sera were sampled to determine the titer of antibody against Peste des Petits Ruminants virus (PPRv) at different time. There was no side reaction observed during the trials. The proportion of positive sera to inoculated animals was 89.6%, 93.6%, 83.95% respectively after 3 months, 15 months and 26 months. The results showed that the vaccine was safe and effective to sheep and goats, and the duration of immunity exceed 26 months at least. |
