One of the horses in the barn is currently in ICU at the local vet hospital due to an infection from a vaccine. Originally they thought it was a reaction to the vaccine itself, but now they believe its an anaerobic infection. They have cut slits into her neck to open the muscle to oxygen as that's the only way to save her; pics farther down, but be warned it's bloody and gross. They've already had to remove some necrotic tissue around the injection site.
The mare, as well as the owner's two other horses, were vaccinated by our vet Tuesday afternoon. Wednesday morning the BO texted the owner saying the mare wasn't eating, didn't want to move, and looked pretty bad. The owner didn't come out till that afternoon to check on the horse, and by that point her entire neck was swollen and she still wouldn't move or eat. She called the vet and he came out and gave a dose of banamine as well as some topical ointment to help reduce the swelling. At 8pm last night, after the owner came out for a night check, the mare was worse and they loaded up to head to the hospital.
The vaccine that caused this was a rabies vaccine. I've only ever given a rabies vaccine once, when Phoenix was being used for 4H and it was required. He didn't have a problem with it. My vet said, as he was giving the shot that he didn't think it was necessary and he's never seen a rabid horse in 30+yrs of practice. I have no idea why the mare's owner choose to give the rabies, since I know my vet (whose she uses) wouldn't recommend it. Has anyone give the rabies shot? I didn't even know they had one till I was told Phoenix would need it. My ponies are due for their yearly shots and I'm kinda freaked out and no way in hell are they getting a rabies vaccine.
