Vaccinating a horse is critical to prevent spreadable diseases, such as rabies, tetanus, West Nile Virus, Eastern and Western Equine Encephalitis, and others. Non-core vaccines tackle equine influenza, equine herpesvirus, strangles, equine viral arteritis, rotaviral diarrhea, anthrax, and botulism. Vaccination recommendations by your veterinarian will vary by location, the horse’s age, sex, breed, overall condition, whether they are likely to come in contact with wildlife or other horses, as well as other risk factors. Other topics discussed by Horse Illustrated articles include whether to vaccinate yourself or have your veterinarian vaccinate, side effects, timing of vaccines, frequency, immunity, disease risk, and more. Veterinarians and other horse care experts weigh in on this very important topic.
