West Nile-Innovator vaccines aid in the prevention of West Nile; equine encephalomyelitis due to Eastern, Western and Venezuelan viruses; and tetanus. West Nile-Innovator is the veterinarian's first choice for core disease protection and has been shown to provide an immune response to West Nile virus that is four times more than a big one-shot combination vaccine. West Nile virus is fatal in 33% of horses that exhibit clinical signs of disease. Vaccination is the most effective way to help protect horses against West Nile virus and other mosquito-borne diseases, such as Eastern equine encephalitis (EEE) and Western equine encephalitis (WEE). If vaccinated, horses have shown to be 30 times less likely to contract West Nile virus. West Nile-Innovator vaccines contain the adjuvant MetaStim, which is designed for safe, enhanced presentation of antigens to the horse's immune system. MetaStim features a dual-phase formulation shown to stimulate both cell-mediated and humoral immunity to West Nile virus. Only Innovator vaccines from Zoetis are adjuvanted with MetaStim for improved immune response. | Zoetis West Nile-Innovator Virus Vaccine | Size Single Dose
