Virbac has announced that the Bluetongue vaccine, Syvazul BTV 3, that the company distributes, has been granted a marketing authorisation in Great Britain for use in cattle and sheep, with a reduced dose in cattle.
The company says the main breakthrough in this new authorisation is that the dose for cattle has been reduced from 4 ml to 2 ml, improving convenience and aligning with the latest regulatory data.
In cattle, the vaccine is indicated for active immunisation to reduce viraemia caused by BTV-3.
The onset of immunity is 3 weeks after completing the primary vaccination course.
The vaccine can be given to cattle from 2 months of age in naïve animals, or from 3 months if born to immune dams.
For the primary vaccination, two doses of 2ml are given, 3 weeks apart, intramuscularly.
In sheep, the vaccine is indicated for active immunisation to reduce viraemia, mortality, clinical signs and lesions caused by BTV-3.
The onset of immunity is 4 weeks after completing the primary vaccination course.
The vaccine can be given to sheep from 3 months of age, subcutaneously.
For the primary vaccination, one dose of 2 ml is given.
