Scabigard® is a living vaccine which induces immunity by producing a mild, “controlled” form of the disease at a protected vaccination site. Scabigard is administered to lambs and sheep through a dermal scratch inside the front leg or brisket with a Scabigard applicator. The scratch must form a scab or ‘take’ on the skin which can be visible within 10 days after administration and drops off after 3-4 weeks. Scabby mouth immunity will last a minimum of 12 months with continual protection with natural exposure. Scabigard vaccine and Scabby Mouth are transmissible to humans, please take all precautious to avoid direct human contact and follow label instructions for use.nants).
