INFORCE 3® Intranasal Cattle Vaccine


For effective respiratory protection against Infectious Bovine Rhinotracheitis, Parainfluenza 3, Bovine Respiratory Syncytial Virus

Respiratory disease can challenge young calves, and even the cowherd. Use the proven option to stop respiratory problems before they start, with INFORCE 3, the market leader since 20151. INFORCE 3 is for the vaccination of healthy cattle, including pregnant cows, for the prevention of respiratory disease caused by BRSV, and as an aid in preventing respiratory disease caused by IBR and PI3.

Collapse All
  • INFORCE 3 is the first and only intranasal respiratory vaccine that prevents respiratory disease cause by BRSV, while also aiding in the prevention of IBR and PI3, to help get cattle off to a healthier, more productive start.

    INFORCE 3 has seen continued improvements since its approval in 2010, including a six-month duration of immunity claim for infectious bovine rhinotracheitis (IBR) protection, and a single nostril administration claim. Additonal research also demonstrated no maternal antibody interference for IBR and bovine respiratory syncytial virus (BRSV).2,3

    Proven Respiratory Disease Protection

    • All calves vaccinated with INFORCE 3 survived a severe BRSV challenge in which all unvaccinated controls died.4,5
    • North Dakota research demonstrated that vaccination with INFORCE 3 at birth improved immune response when boosted at preweaning with a combination respiratory vaccine (BOVI-SHIELD GOLD ONE SHOT).6
    • Additionally, INFORCE 3 was shown to help prevent respiratory disease caused by IBR and PI3, and reduce level and duration of IBR and PI3 viral shedding.7,8,9
    • Current research comparing INFORCE 3 and TSV-2 has demonstrated that vaccinating cows and heifers for BRSV prior to freshening may support overall positive production:
      • 205 pounds more milk per cow per lactation10
      • $36 greater income per cow10
    • For dairy herds, INFORCE 3 can be used in newborn calves, on arrival, at weaning, before moving to group pens, or with cows and heifers prefreshening
    • INFORCE 3 can be used in beef herds in newborn calves and calves at branding, preconditioning, weaning, pre-shipment, or on arrival in stocker or feedlot operations.

    Safe for all ages, types and classes of cattle

    INFORCE 3 is safe for use in all types, ages and classes of cattle. INFORCE 3 was demonstrated safe for use in very young, high-stress calves, weaned and high-stress stocker calves, and pregnant heifers and cows.

    The Science Behind Effective Control

    • Intranasal administration works with the animal's immune system for fast, effective response
    • Helps prime the immune system for a memory response to subsequent vaccinations as well as disease challenges
    • Contains proprietary, temperature-sensitive IBR and PI3 strains that replicate most effectively in the upper respiratory tract
    • Helps deliver a healthy start for young dairy and beef calves

  • Directions

    Aseptically rehydrate the freeze-dried vaccine with the sterile diluent provided, mix well, and administer 2 mL intranasally (IN) using a cannula. Place the 2 mL dose in a single nostril.

    Calves vaccinated before the age of 6 months should be revaccinated after 6 months of age to avoid possible maternal antibody interference with immunization. Annual revaccination with a single dose is recommended.

    INFORCE 3 is available in four vial sizes: 1-dose, 10-dose, 25-dose and 50-dose

  • Precautions

    Store at 2°–8°C. Prolonged exposure to higher temperatures and/or direct sunlight may adversely affect potency. Do not freeze.

    Use entire contents when first opened.

    Sterilized syringes should be used to administer this vaccine. Do not sterilize with chemicals because traces of disinfectant may inactivate the vaccine.

    Burn containers and all unused contents.

    Do not vaccinate within 21 days before slaughter.
