Rabies Vaccine

Killed Virus

Rabies 3 Year

DESCRIPTION: IMRAB® 3 contains the same virus strain that is used in the Pasteur Merieux Connaught human vaccine. The virus is grown in a stable cell line, inactivated, and mixed with a safe and potent adjuvant. Safety and immunogenicity of this product have been demonstrated by vaccination and challenge tests in susceptible animals.

INDICATIONS: IMRAB® 3 is recommended for the vaccination of healthy cats, dogs, sheep, cattle, horses, and ferrets 12 weeks of age and older for prevention of disease due to rabies virus.

DOSAGE: Aseptically inject 1 mL (1 dose) subcutaneously or intramuscularly into healthy cats or dogs; 2 mL into healthy sheep, cattle, and horses. Inject 1 mL subcutaneously into healthy ferrets. Revaccinate ferrets, cattle, and horses annually; cats, dogs, and sheep 1 year after first vaccination, then every 3 years.

PRECAUTIONS: Store at 2-7°C (35-45°F). Do not freeze. Do not vaccinate food producing animals within 21 days prior to slaughter. Shake well before using. Use entire contents when first opened. Do not use chemicals to sterilize syringes and needles. Contains gentamicin as a preservative. A transient local reaction may occur at the injection site following subcutaneous administration. Some reports suggest that in cats, the administration of certain veterinary biologicals may induce the development of injection site fibrosarcomas. In rare instances, administration of vaccines may cause lethargy, fever, and inflammatory or hypersensitivity types of reactions. Treatment may include antihistamines, anti-inflammatories, and/or epinephrine.
