- Inactivated bovine rotavirus strain TM-91
- Serotype G6P1 Inactivated bovine coronavirus strain C-197
- Escherichia coli strain EC/17 expressing adhesin F5 (K99)
Active immunisation of healthy pregnant cows and heifers to provide calves with passive immunity targeted at reducing mortality, and the incidence and severity of diarrhoea from gastrointestinal infections caused by enterotoxigenic Escherichia coli, Bovine rotavirus and Bovine coronavirus.
Passive immunity in calves starts with colostrum feeding and is dependent on calves receiving sufficient colostrum after birth.
Onset of immunity: Passive immunity in calves starts with colostrum feeding.
Dosage and administration
Route: Subcutaneously or Intramuscularly in the anterior third of the neck. Avoid inadvertent intravascular administration.
Unvaccinated cows: 3 mL vaccination 5-12 weeks prior to calving
Vaccinated cows: 3 mL vaccination during each pregnancy 3-12 weeks prior to calving
- Common aseptic procedures should be used during vaccination
- Use only sterile syringes and needles.
- Allow the vaccine to come to 18 to 22°C before use.
- Shake well before and occasionally during administration.
Protection of calves depends on the presence of colostral antibodies (obtained from vaccinated cows) in the gut during the first weeks of life until the individual immune status of the calves is formed. An adequate intake of colostrum throughout first 2-3 weeks of life is required to optimise efficacy from vaccination. All calves must be supplied with a sufficient volume of colostrum within six hours after calving. The peak concentration of antibodies in the colostrum occurs between 0 and 24h after parturition. In herds with unfavourable epizooological situations, collecting colostrum from vaccinated mothers from the first 6 - 8 milkings is recommended. To maintain lactogenic immunity calves must be fed with stored colostrum (2.5 - 3 litres per day) for at least the first two weeks of life.
To optimise the decrease in calf morbidity and reduction of intensity of diarrhoea whole herd vaccination is required. All newborn calves must be fed with the antibody enhanced colostrum.
This inactivated oil vaccine is prepared from chemically inactivated virus antigens derived from bovine rotavirus strain TM- 91 and bovine coronavirus strain C-197 propagated in the established cell cultures, and from Escherichia coli expressing adhesin F5 (K99) propagated in the liquid growth medium.The vaccine is designed to stimulate antibody production of pregnant cows against these antigens, which are then transferred to calves when fed colostrum/milk.
Best practice calf rearing, paying attention to facilities and hygiene, is recommended to maximise vaccine efficacy and minimise disease challenge.
Do not vaccinate ill or unhealthy animals.
Do not mix with any other vaccine or immunological product.
Adverse reactions (frequency and seriousness)
Occasionally a slight swelling up to 2 cm in diameter may be observed at the site of injection. It will reabsorb within 14 days of injection. If intravascular injection occurs, cerebral or cardiac embolism may occur resulting in staggering or even death.
Use during pregnancy
The medicinal product is designated for the use in cows in the last trimester of pregnancy.
Interaction with other medicinal products and other forms of interaction
No information is available on the safety and efficacy from the concurrent use of this vaccine with any other
