Intervet Adds VEE Strain Line to Vaccine Line

Intervet is giving horse owners an opportunity to defend horses against another deadly strain of equine encephalomyelitis. Intervet now offers selected Encevac vaccines with added protection from Venezuelan Equine Encephalomyelitis (VEE).

The addition of the VEE strain is important for several reasons. VEE can affect both horses and humans, and after a 20-year absence, equine epizootics caused by the Venezuelan equine encephalomyelitis VEE virus, occurred again in Venezuela and Colombia in 1995, and in Mexico in 1993 and 1996.

The VEE virus is spread by insect vectors such as mosquitoes. VEE can’ t be differentiated from the other types of encephalitis by clinical signs only; additional laboratory confirmation is needed.

Intervet, based in Millsboro, Del., focuses on the research, development, manufacturing and marketing of veterinary products for a number of species including horses, cattle, swine, poultry, cats, dogs, goats, sheep and fish. For more information, visit
