703RISK OR LOSS FUNCTION AND QUALITY MEASURES FOR RIFT VALLEY FEVER VACCINE PRODUCTIONRift valley fever (RVF) is an arthropod-borne disease. It is a zoonotic disease and spread in Africa, Madagascar and Arabian Peninsula. Mosquito is the principal vector of the disease. This paper evaluates risk or loss function and quality measures for RVF vaccine. The likelihood of risk was estimated by 0.29% and the risk function was 0.05 which is statistically non significant (P-Value>0.05). This returns in safety, cost-effectiveness and immunogenicity of the vaccine produced. The results concluded that acceptable risk level should be measured and quality control and good veterinary and laboratory practi ces are essential for safe and effective RVF vaccineahmed.hasbo@ymail.comResearch6122015Risk or loss function,quality control,RVF vaccine,SudanMohammed Elsadig Ahmed Mansour,Tamador Mohamed Abdallah Elhassan,Nahid Ahmed Ibrahim,Shima Hassan Alfaki,Awatif Abass AhmedRift Valley Fever Unit, Veterinary Research Institute, Soba, Madani Street, P.O.Box 8067, Khartoum, Sudan,Rift Valley Fever Unit, Veterinary Research Institute, Soba, Madani Street, P.O.Box 8067, Khartoum, Sudan,Rift Valley Fever Unit, Veterinary Research Institute, Soba, Madani Street, P.O.Box 8067, Khartoum, Sudan,Rift Valley Fever Unit, Veterinary Research Institute, Soba, Madani Street, P.O.Box 8067, Khartoum, Sudan,Rift Valley Fever Unit, Veterinary Research Institute, Soba, Madani Street, P.O.Box 8067, Khartoum, Sudan
