West Nile EWT

West Nile EWT by Zoetis is a vaccine used in the prevention of viremia caused by West Nile and equine encephalomyelitis caused by tetanus, and Eastern and Western viruses. 

This vaccine is intended for healthy horses.

Prior to injecting, properly cleanse injection site using the antiseptic technique. Give 1mL intramuscularly once per year. A booster dose can be given 3-4 weeks after initial dose in unvaccinated or naive horses. Early revaccination may be advisable when horses are faced with an outbreak or with other conditions which might make heavy exposure likely.

Always consult your veterinarian before beginning a vaccination plan. As with most medications, side effects are possible. A temporary reaction at the injection site is the most common side effect.
