Vaccination is an important part of preventing disease. However, not all vaccines are 100% effective. So vaccination recommendations are different for different farms based on your horses’ risk of disease, the prevalence of the infections in your area this year, the efficacy of the vaccine, where your horses are traveling, the movement of horses on and off your farm, the age and sex of your horses and your budget”. For more information on how to decide which vaccines are best for your horses, please refer to the AAEP link at the bottom of the page or give your vet a call.
