1. General Directions: Vaccination of healthy cattle is recommended. Aseptically rehydrate the freeze-dried bacterin-toxoid with the accompanying adjuvant-containing sterile diluent, shake well, and administer 2 mL subcutaneously. In accordance with Beef Quality Assurance guidelines, this product should be administered subcutaneously (SC) under the skin. Healthy cattle should be vaccinated a minimum of 14 days prior to weaning, shipping, or exposure to stress or infectious conditions.
2. Primary Vaccination: Administer a single dose to healthy cattle. Only a single dose is necessary to confer active immunity. Good management practices support revaccination whenever subsequent stress or exposure is likely.
3. Good animal husbandry and herd health management practices should be employed.
