Covexin 8 For Sheep

For the active immunisation of sheep and cattle from 2 weeks of age against disease associated with infections caused by C. perfringens Type B, C. perfringens Type C, C. perfringens Type D, C. chauvoei, C. novyi Type B, C. septicum, C. haemolyticum and against tetanus caused by C. tetani. For passive immunisation of lambs and calves against infections caused by the above mentioned clostridial species (except C. haemolyticum in sheep). Onset of immunity is two weeks after the primary course.


Covexin 8 is designed as a vaccine for of sheep and cattle against diseases caused by Clostridial bacteria. The herd or flock should be vaccinated at least two weeks before a period of risk. This period of risk could include events such as breeding, parturition and housing. Sheep and lambs over 8 weeks of age should get a 5 ml initial dose followed by a 2 ml dose 6 weeks later. Lambs 2-8 weeks of age, from unvaccinated ewes or ewes of unknown vaccination status should get a 2 ml initial dose followed by a second 2 ml dose 4-6 weeks later.

Cattle of all ages can receive a 5 ml initial dose followed by a second 5 ml dose 6 weeks later. A single dose (2 ml for sheep, 5 ml for cattle) should be administered at 12 month intervals. By subcutaneous injection preferably in the loose skin on the side of the neck, observing aseptic precautions. Shake thoroughly before use. In the event of an anaphylactic reaction appropriate treatment such as adrenaline should be administered without delay.


For the vaccination of healthy cattle and sheep as an aid in the prevention of diseases caused by Clostridium chauvoei, C. septicum, C. novyi Type B, C. haemolyticum (known also as C. novyi Type D), C. tetani and C. perfringens Types C and D.

Immunity is also provided as an aid in the prevention of diseases caused by the beta and epsilon toxins of an additional organism, C. perfringens Type B. Although C. perfringens Type B is not a significant problem in North America (US), immunity is derived from a combination of Type C (beta) and Type D (epsilon) C. perfringens fractions.

Administration And Dosage

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.

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.
