Fort Dodge Animal Health announces the launch of West Nile-Innovator DNA, a novel vaccine for horses to aid in the prevention of West Nile virus.

Unlike conventional vaccines, which rely on the foreign proteins derived from disease-causing agents, West Nile-Innovator DNA uses purified DNA plasmids to stimulate an immune response. The vaccine contains no live or killed viruses, no live vector or viral proteins, and there is no risk of reversion to virulence.

West Nile-Innovator DNA provides 12 months of immunity after two initial doses, and it is greater than 99 percent reaction-free. Annual revaccination requires one dose.

West Nile-Innovator DNA will be sold only to veterinarians. For more information, contact Fort Dodge Animal Health; P.O. Box 25945, Overland Park, KS, 66225; 800/685-5656; www.fortdodgelivestock.com
