Blue Tongue Vaccine For Sheep

Bluetongue (BT) is a hemorrhagic disease of wild and domestic ruminants caused by bluetongue virus (BTV). BT is one of the main veterinary diseases worldwide causing significant economic losses. The outcome of BTV infection varies and depends on the pathogenicity of the virus strain and the susceptibility of the ruminant host. Indigenous ruminants in BT endemic areas, goats, and cattle are less susceptible than many sheep breeds from BT-free areas. Sheep can induce severe clinical disease , whereas cattle rarely show clinical disease but are readily infected and are an epidemiologically important BTV reservoir.

BTV is not contagious but transmitted by biting competent Culicoides midges , whereas several recently discovered BTV serotypes spread without midges by direct contact transmission . Virulent BTV can also spread oro-nasally or vertically and have been reported in the field . A role of transplacental transmission in overwintering has been hypothesized, and trade of pregnant heifers can transport infectious BTV over long distances potentially causing outbreaks in former BT-free areas by delivery of viremic fetuses .

Description

Bluetongue Vaccine is for the vaccination of healthy sheep and goats against type 10 bluetongue infections. Do not vaccinate pregnant animals. It is recommended that all breeding stock should be vaccinated for Bluetongue approximately three weeks prior to the breeding season or after lambing. Lambs should be vaccinated as they approach weaning, vaccinating too young can cause the maternal antibodies to interfere with the proper active immune response. Contains Penicillin and streptomycin as preservatives. 21 day withdrawal. Supplied as a 50 dose bottle. Needles and syringes sold separately.

Features of Blue Tongue Vaccine For Sheep

The use of vaccines has proven to be very effective in controlling and eradicating infectious diseases, both in veterinary and human medicine; however, vaccines can be also the source of an array of problems caused by procedures such as overimmunization. Bluetongue, an orbiviral disease that affects ruminants, is best controlled by the use of inactivated vaccines. During the last years of the past decade, these vaccines were applied all over Europe to control the spreading of the disease, a goal that was accomplished; however, at the same time, several adverse effects related to the vaccination were reported.

Especially in sheep, this vaccination campaign brought out a new cachectic and neurologic disease with harmful consequences for the ovine industry. This disease is now recognized as the ovine version of the autoimmune/inflammatory syndrome induced by adjuvants (ASIA syndrome) and poses an immense challenge in veterinary medicine, immunology, and vaccinology.

Dosage and Administration

The incidence of bluetongue is seasonal, with animals usually contracting the disease in August and September due to the virus being transmitted by biting insects. Treatment is almost totally ineffective and preventive vaccination, late in the spring or in the early summer is not only recommended but becomes vitally important.

Lambs from immune ewes carry a degree of resistance to bluetongue which may last as long as three (3) months. As lambs approach weaning time the maternal antibody disappears and the acquired resistance can breakdown in the face of field exposure. It is at this time that lambs should be vaccinated. If vaccinated too young the “maternal antibody” may interfere with the proper active immune response.

The vaccination of pregnant ewes could result in births of abnormal lambs and this practice is not recommended. Instead, all breeding stock should be protected with BLUETONGUE VACCINE approximately three (3) weeks prior to the breeding season or after lambing.

The entire contents of the accompanying vial of diluent should be withdrawn with a syringe and needle and transferred into the vial of dried vaccine. Do not remove the stoppers from either vial. Shake the vaccine bottle until the dried material is completely rehydrated. Live virus products contain a stabilizer that may slow rehydration slightly but complete liquefaction will take place within a few moments. The vaccine is then ready to use. Use only the diluent furnished with the product to rehydrate the vaccine.
