Modified Live Virus
PRODUCT DESCRIPTION: Bovi-Shield IBR is for vaccination of healthy, nonpregnant cattle to prevent respiratory
disease caused by infectious bovine rhinotracheitis (IBR) virus. A duration of immunity of at least 9 months has been
demonstrated. When administered intramuscularly, Bovi-Shield IBR aids in preventing respiratory disease caused by
IBR. Bovi-Shield IBR may be administered to calves nursing pregnant cows provided their dams were vaccinated,
according to label directions, with any Bovi-Shield GOLD FP or PregGuard GOLD FP vaccine within the past 12
months. To help ensure safety in pregnant cattle, heifers must receive at least 2 doses of any Bovi-Shield
GOLD FP or PregGuard GOLD FP product with the second dose administered approximately 30 days
PRODUCT DESCRIPTION: Bovi-Shield IBR is a freeze-dried preparation of a modified live virus (MLV) strain of the
IBR virus, plus a sterile diluent used to rehydrate the freeze-dried vaccine.
General Directions: Vaccination of healthy, nonpregnant cattle is recommended. Aseptically rehydrate the freeze-
dried vaccine with the sterile diluent provided, shake well, and administer 2 mL subcutaneously or intramuscularly. In
accordance with Beef Quality Assurance guidelines, this product should be administered SC in the neck region.
Primary Vaccination: Administer a single 2-mL dose to healthy cattle. To avoid possible maternal antibody
interference with active immunization, calves vaccinated before the age of 6months should be revaccinated after 6
months of age.
