Vaccinating your horse provides protection from deadly viruses. Sometimes, as horse owners we fear the symptoms of vaccination and choose to refrain from putting our horses through stress. Understanding how vaccines may affect your horse may help ease your worries.
Like humans, horses often have reactions similar to the reaction human’s experience after vaccination. It’s fairly common for some horses to experience side effects. Temporary side effects may be seen a few hours after vaccination. Most side effects are mild, and include fever, loss of appetite, and lack of energy or alertness. These reactions are common and normal signs that an immune response has been stimulated. If any of these symptoms continue for more than 24 hours, contact your veterinarian.
