Fort Dodge Animal Health, a division of Wyeth, announced that its West Nile-Innovator DNA vaccine has received FDA approval and is expected to be released in early 2006. It is expected to be available only to licensed veterinarians.
The intramuscular-administered vaccine “causes the horse’s cells to begin making proteins from the West Nile virus, which trigger a protective immune response,” according to Fort Dodge. The company believes this is the first DNA vaccine in the world to be approved for commercial sale.
