What Should be Expected After Vaccinating My Horse?

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.

Vaccines are designed to stimulate an immune response. Each horse is unique and his specific response may be different from other horses. More serious side effects are rare, but can occur. Some horses may have an allergic reaction to the vaccine which will lead to hives, bleeding rash, difficulty breathing; colic and or the horse could even collapse. These symptoms could be life threatening and require immediate attention from your veterinarian.

Reduce the chances of bad reaction to vaccination by first speaking with your veterinarian. Your veterinarian understands your horse and their lifestyle or any allergies your horse may have. Your veterinarian may also know which vaccines offer the best support for your horses unique needs.
