As a service to horse owners everywhere, we prepared this comprehensive yet easy-to-read chart so you can learn which vaccine you need to administer to your horse and protect it against the West Nile Virus, Equine Influenza, Tetanus Toxoid, and more. Vaccinating your horse is the best way to protect it against life-threatening diseases and infections. Equine vaccines should begin when the horse is young to ensure the best results.
