BIVI has been granted conditional license by the USDA for a new vaccine for Equine Rhinitis A Virus (ERAV). ERAV is a potentially overlooked causative agent of respiratory diseases affecting horses. This disease, which affects both upper and lower airways, may be spread by contact through nasal secretions and aerosol inhalation. The role of ERAV in causing acute respiratory disease in horses may be underestimated due to the lack of sensitivity of traditional diagnostic testing. A conditional license is eligible for consideration when it is demonstrated that there is a need in the field for such a product. Efficacy and potency test studies are in progress. A conditionally licensed vaccine may be distributed as authorized in each state, and used by, or under the supervision of veterinarians. For vaccination of healthy horses 4 months of age or older for active immunization against disease caused by Equine Rhinitis A virus.
