Well, it’s supposed to be spring. Some days it doesn’t feel like it with the lovely Chicago tenacious winter clinging, but the calendar is now at the middle of April, and spring will eventually arrive in earnest. It’s one of the main times of year to vaccinate. When it comes to vaccinations it is often prudent to discuss your situation to determine the vaccination program that best fits your horse’s life and risk levels. Recommendations for vaccines do change from time to time and there are different needs for foals, pregnant mares, show horses, and older horses that don’t travel and don’t have other horses coming onto the property that they live.
The term core vaccine is one that is used to refer to a vaccine that is considered to be strongly recommended for nearly all horses. These vaccines have been proved to be efficacious and safe and demonstrate a high benefit to risk ratio. Reasons for a vaccine to be considered “core” include protection a “from a disease that is endemic to a region, potential public health significance, required by law, virulent/highly infectious and/or those posing a risk of severe disease.” Recently the AAEP (American Association of Equine Practicioners) has updated their vaccine recommendations. One of the changes that occurred with these recommendations was the addition of rabies to the set of core vaccines.
Currently the vaccines that are considered core are Tetanus toxoid, Eastern and Western Equine Encephalomyelitis, West Nile virus, and Rabies. Rabies vaccines are ones that must be administered by a veterinarian. Some clients are surprised to hear that the rabies vaccine is one that is strongly recommended, as it is an infrequent disease. Cases are not common in horses, however, when they do occur, it is always with tragic results. We cannot control the wildlife that horses can become exposed to, even in the ideal barn setup. Bats, opossums, raccoons, and skunks are all potential carriers, that could bite a horse and infect them.
One of the reasons that the rabies vaccine is so important is the public health concern. If a horse is found to be infected with rabies, then all people who have handled the horse recently will need to undergo rabies prophylactic treatment – a series of painful injections. A rabid horse may not show signs that one associates with other rabid animals – horses can have the “dumb” form of rabies or less commonly the “furious” form. The dumb form shows signs of lethargy, depression and neurologic signs, compared to the stereotypical aggression associated with the furious form.
The bottom line is, it is best to discuss your own horses’ living situation and lifestyle with your veterinarian. Take your veterinarian’s recommendations seriously, even if you haven’t vaccinated for rabies in the pa
