BLUE TONGUE VACCINE

Bluevac is a family of a modified live virus vaccines recommended for immunization for healthy, non-pregnant sheep against blue tongue caused by birulent field-strain virus.

There are currently three vaccines available for protection against the three strains of bluetongue virus present in California. Bluevac-10 immunizes sheep against International Type 10 virus; similarly, Bluevac-11 immunizes against International Type 11 virus, and Bluevac-17 immunizes against International Type 17 virus .Each vaccine strain will only promote immunity against its homologous field strain virus; there is no cross protection afforded.

If disease occurs in vaccinated sheep, it is important that laboratory assistance be obtained to identify the agent causing it. Laboratory studies and field trials have demonstrated that the modified virus used in these products will not cause disease in vaccinated animals, but will produce a satisfactory strain-specific immunity.

Time to Vaccinate

Bluetongue disease occurs primarily during the months of summer and early fall. For this reason animals should be vaccinated in the spring or early summer to establish immunity before outbreaks occur.

IMPORTANT: DO NOT VACCINATE PREGNANT ANIMALS. The use of this vaccine in pregnant ewes may produce abnormal lambs. While the vaccine does not affect the ewe the fetus may be affected, especially if vaccine is administered during the first third of pregnancy

All breeding stock should be protected with Bluetongue Vaccine approximately three weeks prior to breeding or after lambing.

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.

Directions

  • Store at 2° to 7° C. 
  • 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.

Precautions

In the event of accidental human exposure, consult a physician. Burn, autoclave or chemically disinfect container and all unused contents. Anaphylactoid reaction may occur following administration of products of this nature. If noted, administer adrenalin or equivalent.
