Rehydrate the vaccine (with accompanying diluent) immediately before use. Shake well after rehydration. Use entire contents when first opened. Do not administer to pregnant animals. Do not vaccinate within 21 days before slaughter.
Do not use disinfectants to sterilize equipment.
Treatment is almost totally ineffective and preventive vaccination, late in the Spring or in the early Summer not only is recommended but becomes vitally important.
Lambs from immune ewes carry a degree of resistance to Bluetongue which may last as long as 3 months. Lambs should be vaccinated close to weaning time as this is the time when maternal antibodies disappear. If vaccinated too young, the maternal antibodies may interfere with proper active immune response.
All breeding stock should be protected with Bluetongue Vaccine approximately three weeks prior to breeding or after lambing.
