An experiment was conducted to evaluate the safety and efficacy of seven commercial vaccines against C. chauvoei. 120 weaning calves were divided into 8 groups of 15 animals; 7 groups were each assigned to one of the seven vaccines and one group served as the control. Blood samples were taken on days 0, 20, 48, and 76 after vaccination. Levels of antibodies against C. chauvoei were determined using ELISA and a minimum level of protection was established.
