Administration And Dosage

Cattle

In order that a balanced response to vaccination is obtained, a primary course of two injections of 4 mL each should be given with an interval of 6 weeks between injections. To maintain a constant high level of immunity, booster injections should be administered at intervals of 6 months, or when outbreaks are seasonal, at least 2 weeks before the anticipated outbreak. Calves vaccinated under 3 months of age should be revaccinated at 4-6 months of age. Calves vaccinated at 3 months of age or older should be revaccinated 6 weeks later. Inject subcutaneously with strict aseptic precautions.

Sheep

On being vaccinated for the first time, all classes of sheep must be given a 4 mL dose followed by a further 2 mL dose 6 weeks later. This primary course should be completed at least 2 weeks before maximum immunity is required. This may be either a period of risk or, in pregnant ewes, during lambing. Revaccination with 2 mL is required at six-month intervals for continuous protection, but where there is no period of risk in the winter annual revaccination is all that is necessary. In lambing flocks, pregnant ewes should be injected 2 weeks before lambing is due to commence. They will then be able to pass on enough antibodies in the colostrum to enable their lambs to be passively protected for the first 12-16 weeks of life, provided the lambs suck normally within the first 12 hours of birth. Replacements born of vaccinated ewes should receive the first dose of the primary course at 10-12 weeks of age. Administration is by subcutaneous injection. Injections should be made through an area of clean, dry skin, over the chest wall, behind the shoulder, observing strict aseptic precautions.
