Developed specifically for intranasal use

INFORCEā„¢ 3 respiratory vaccine was developed for intranasal administration. Intranasal vaccines:

  • Help stimulate immunity where pathogens attack first
  • Trigger a quick immune response
  • Help prime the immune system for a memory response to subsequent disease challenges


  • Aseptically rehydrate the freeze-dried vaccine with the sterile diluent provided; shake well.
  • Administer 2 mL intranasally (IN) using a cannula or a syringe with the needle removed. Place half the dose (1 mL) in each 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 doses, 25 doses and 50 doses.
