Abstract: Calves vaccinated twice with one commercial pomona vaccine had serum MAT titres up to 1:300, warm CFT titres of 1:20 and cold CFT titres of up to 1:80. A second commercial vaccine did not elicit any detectable antibodies. All calves, vaccinated as well as unvaccinated, showed a rapid rise in antibody levels, detectable with all three tests, following challenge with 38 x 10⁸ pomona organisms.
