DOSE: Aseptically rehydrate with the entire contents of the accompanying sterile diluent. Instill the entire rehydrated vaccine into one nostril using a syringe with applicator tip. Administer a second dose 2 to 3 weeks later. Historically, annual revaccination with this product was recommended. The need for annual booster vaccinations has not been established; consultation with a veterinarian or the manufacturer is recommended.

This product contains live bacteria and is designed for intranasal use only. Disinfect hands and equipment after use. Contamination of the user’s hands or equipment with reconstituted vaccine could lead to infections if proper disinfection practices are not followed prior to procedures that require asepsis. Injection equipment used to reconstitute or administer Pinnacle I.N. should not be reused, and should be disposed of appropriately.

Pinnacle I.N. Caution

In case of anaphylactoid reaction, administer epinephrine. After administration, a small number of horses may experience non-contagious transitory upper respiratory signs including transient, noncontagious nasal discharge from 1 day to 3 weeks post vaccination. A small number of horses may experience abscess and/or lymphadenopathy within 1-7 weeks post-vaccination. Fever may also be noted after vaccination. Purpura hemorrhagica may be seen in hypersensitive individuals following exposure to streptococcal proteins. Store in the dark at 2°C to 8°C (35° to 46°F). Do not freeze. Shake well after rehydration. Do not vaccinate within 30 days before slaughter. Use entire contents when first opened. Inactivate unused contents before disposal.
