Infectious Cattle Diseases and Vaccines
Vaccines are available for 20 to 30 infectious diseases of cattle. With the various brand names and different combinations available, the choice of vaccines can become very complicated. Calves vaccinated under 6 months of age should generally be re-vaccinated again after that age to provide a longer lasting immunity. It is important to follow the specific directions provided with a vaccine. If two doses are recommended initially, don’t count on very much protection until 7–14 days after the second dose has been given. The major diseases for which vaccines are available are categorized and briefly described below.
