BHV1-Reaktivierung nach verschiedenen Infektions- und Vakzinierungsarten

The elimination of field virus infection by live attenuated vaccines was found to be impossible in three experiments. These also indicated that it is not possible to prevent infection with a field virus by prophylactic vaccination. Intravenous vaccination stimulates the production of humoral antibodies, but does not provide a protective immunity. Following the administration of cortico-steroids, infections were more easily established. From the results obtained it is important to reconsider vaccination protocols
