Peste des petits ruminants (PPR), an acute viral disease that primarily affects goats and sheep, has been discovered in Sub-Saharan Africa, Arabia, the Middle East, and Southern Asia. Several outbreaks of this disease have been reported in various Indian states. Due to high mortality in both young and adult ruminants, the disease is causing a high economic disaster in small ruminants. Support for diagnostic techniques and timely vaccination of the vulnerable population are required for effective PPR control and elimination. The current study looked at the immune responses of 30 goats after they were immunized with the Sungri 96 strain of PPR vaccine. From 15 to 90 days after vaccination, the immune response to the PPR vaccine was assessed using competitive ELISA (c-ELISA). In goats, the pre-vaccination mean percentage inhibition (PI) value was 10.14. The mean percentage inhibition (PI) values on the 15th, 30^th, 45^th, 60^th, 75^th, and 90th days after vaccination were 44.54, 61.52, 72.80, 71.07, 67.35, and 66.05. Antibody titers remained above the level of protection in all animals 30 to 90 days after vaccination. An age-based study of goat immune responses to PPR vaccine revealed no significant (p 0.05) differences between age groups.
