Precipitin response of cattle to commercial wart vaccine.
Fifty young bulls were given commercial wart vaccine upon their arrival at a bull stud establishment. The bulls were given 2 additional vaccinations 2 and 24 weeks later. The precipitin antibody response of these bulls to bovine papilloma virus was monitored. Antibody levels increased significantly, particularly after the 3rd vaccination was given at 24 weeks, but decreased markedly within 20 weeks after the last vaccination was given. These results demonstrated that formalin-inactivated bovine papilloma virus was capable of inducing precipitin antibody similar to infective bovine papilloma virus. Multiple, repeated vaccination provided the best serologic response.
