Scabivax Forte is used for the active immunisation of sheep and lambs against Orf to reduce clinical signs and/or lesions of the disease. Immunity develops within 4-8 weeks of vaccination and is protective against severe signs of contagious pustular dermatitis for at least 12 months. The vaccine should not be used on farms or in flocks where Orf disease is not a problem.
Do not vaccinate ewes less than 7 weeks before lambing. Do not vaccinate pregnant ewes except at the recommended stage of pregnancy.
Special precautions for use in animals
Scabivax Forte is a live virus vaccine, and thus care must be taken to apply the vaccine only to the intended vaccination site and to not contaminate other sites such as mouth, feet, superficial wounds or abraded skin of the animal. Vaccinated lambs may transmit the disease to ewes’ udders.
Ewes that are vaccinated prior to lambing should not be moved to the proposed place of lambing until sufficient time has passed for the scabs to drop off (minimum of 7 weeks).
Where indoor housing is practiced, routine cleansing and disinfection of the premises is an important aid in the control of Orf. In cases where vaccination of lambs cannot be delayed until turnout, veterinary advice should be sought as to how to minimise the risk of infection.
Ewes with unvaccinated lambs at foot are best to have their vaccination delayed until the lambs are weaned, except in case of emergency. Vaccinate these ewes as for pregnant ewes.
For a period of up to 7 weeks after vaccination, or until the scabs resulting from the vaccine “take” have dropped totally, animals will be shedding virus infected scabs. During this time, vaccinated animals should not be:
- allowed access to lambing pens or pasture where ewes and their lambs will subsequently be grazed;
- allowed to come into contact with unvaccinated sheep and susceptible species;
- marketed, slaughtered or shorn
Care must be taken not to contaminate the ground area with vaccine or used materials due to the persistence of Orf virus in the environment.
Do not vaccinate ewes or lambs during wet weather.
Vaccination of ewes before lambing will not provide protective immunity to the lambs via the colostrum. Therefore, if Orf disease is a problem in the lamb flock as well, the lambs should also be vaccinated to ensure protection throughout the entire flock.
Special precautions to be taken by the person administering the product to animals
Orf disease is caused by a virus which is communicable to man. The vaccine is capable of causing a skin infection in humans so should not be used by immuno-suppressed individuals. In the case of accidental self-administration (injection or scratch), ingestion or spillage onto the skin or into the eye, seek medical advice immediately and show the package insert or label to the physician. Rubber gloves should be worn when handling this product or dismantling the Applicator. Hands and arms should be washed after vaccination.
