Reconstitute the vaccine by mixing the freeze-dried component with the liquid fraction and shake well. Administer the reconstituted vaccine by the intramuscular route.

For cattle from 12 weeks of age two doses three to four weeks apart.

Animals should preferably be vaccinated at least 3 weeks before a period of stress or high infection risk like re-grouping, transport of animals or the start of the autumn season.

A duration of immunity of 6 months has been demonstrated by challenge studies for BRSV and BVD type 1 virus. If protection in excess of this period is required, then animals should be re-vaccinated after 6 months.
