Vaccinations for the Beef Cow Herd
James G. Floyd, Jr., Extension Veterinarian, Professor, Animal and Dairy Sciences, Auburn University
Vaccination programs for beef cow herds are designed to protect animals in the herd against disease caused by infectious organisms, such as viruses or bacteria. Vaccines contain killed or modified live organisms which do not cause disease but stimulate the animal’s immune system to mount a response. The immune system will then “remember” how to mount a response against the organism if it is infected with that organism later. A vaccine cannot prevent infection but will increase the animal’s ability to throw off the infection or lessen the severity of the disease.
The majority of cattle vaccines are injected, although some may be given by other routes, such as intranasal or oral. Although antibiotics, such as penicillin or tetracycline, are also often administered by injection, treating an animal with one of those drugs is not a vaccination.
