[Vaccination of cattle against respiratory disease caused by virus infection (author's transl)].
Studies on the epizootiology of respiratory viruses in herds of cattle showed that infection by bovine respiratory syncytial (BRS) virus was a major cause of bovine respiratory disease in calves. Moreover, of IBR virus infection associated with respiratory symptoms were observed in the Netherlands since the Spring of 1974. Outbreaks of IBR virus infections occur throughout the Netherlands today. Initially, outbreaks ran a course marked by the typical symptoms of haemorhagic rhinitis, observed particularly in cows. Today, IBR virus infections have become enzootic on several farms, the majority of infections in young cattle being accompanied by respiratory symptoms that are identified as being due to IBR virus infection. Other virus infections that may cause respiratory disease, parainfluenza virus 3, adeno viruses and bovine virus diarrhoea (BVD) virus, were found to be enzootic in most herds in the Netherlands. However, there is no definite correlation between the occurrence of these infections and clinical symptoms. The use of vaccines against these virus infections is not advisable in the present situation. A vaccine against BRS virus infections is commerically available. Immunization by this vaccine against the pulmonary symptoms of BRS virus infection should be verified by a field trial. Unvaccinated control groups of calves should be included. In the experience of the present author, the immunity produced by this vaccine cannot prevent infection by the field strain of BRS virus. Postvaccination reactions were observed within seven days after vaccination with this vaccine in some cases. These were attributable to non-cytopathogenic strains of BVD virus, contaminating some batches of this commerical vaccine.
