One Vaccine Protects Against Three Diseases
Wyeth Animal Health is proud to introduce West Nile-InnovatorTM + EWT, the first and only vaccine to protect horses against the mosquito-borne diseases of West Nile virus, and Eastern and Western Encephalomyelitis.
Since its discovery in the United States in 1999, West Nile virus has spread across North America at an alarming rate. Cases of Eastern Equine Encephalomyelitis (EEE/Sleeping Sickness) are up nearly 8,000 per cent in some areas. One in three clinically affected horses will die of WestNile disease, while nine in ten horses will die from EEE/Sleeping Sickness.
Horse owners are urged to continue to vaccinate against West Nile virus. “It’s important to remember that vaccines which protect your horse against Eastern and Western Equine Encephalomyelitis do not protect against encephalomyelitis caused by West Nile virus,” Catherine Martin, Equine Product Manager for Wyeth Animal Health said. “If you vaccinate against EEE, you should vaccinate against West Nile virus as well. West Nile-InnovatorTM + EWT is available in two convenient combinations, with or without Tetanus for customized protection.”
Fort Dodge Animal Health, a division of Wyeth, developed the West Nile-InnovatorTM vaccine immediately after the disease began appearing in the United States in 1999. Provinces that actively began vaccinating horses in the fall of 2002 experienced a decline in equine cases in 2004, despite the rise of human cases and positive mosquito pools. Efficacy data Wyeth has received from both challenge and field studies prove that West Nile-InnovatorTM vaccination protocols are 95 per cent effective in protecting horses against this devastating disease.
The American Association of Equine Practitioners recommends that due to the unpredictable nature of the exposure and geographic distribution of West Nile, all horses should be immunized against the disease. The current 2005 AAEP guidelines suggest primary WNV vaccination of previously non-vaccinated horses involves administration of two doses of vaccine three to six weeks apart followed by an annual booster prior to expected risk or mosquito season. This is consistent with vaccination recommendations for Eastern and Western Encephalomyelitis. A complete schedule of vaccination guidelines is available through the AAEP and through Wyeth Animal Health.
