VACCINATION

• The tissue culture rinderpest vaccine at a dose of 102.5 TCID50 protects goats for at least 12 months against PPR. The vaccine is currently used in many African countries for vaccination against PPR. This vaccine interferes with rinderpest eradication programmes because it is impossible to determine if seropositive small ruminants have been vaccinated or naturally infected with RPV.
• A homologous attenuated PPR vaccine is being tested and may soon be commercially available. In Southern India, a homologous PPR vaccine using AR-87 strain is used to control PPR in sheep and goat. This vaccine was developed at the Department of Veterinary Microbiology, Madras Veterinary College.
