Hoping to draw on COTH collective experience here. There seems to be a supply issue with the rabies vaccine my vet usually administers, so they used a different source - which is the same kind they used about 5-6 years prior. This particular vaccine has a tendency to cause a lot of muscle soreness, so because it is also indicated for subcutaneous administration, my vet decided to go that route to save some pain and soreness for our barn.
ALL the horses got big swollen lumps at the injection site and were tender, but aside from a couple who required one dose of banamine to get through, they all bounced back with no issue.
Except, of course, my mare. The vaccine was administered last Thursday. Since then her appetite is almost non-existent, she has drunk less than a litre of water on her own, and she is dull and lethargic. Her temperature has remained relatively normal, but has fluctuated up and down by ~1 degree. She got banamine every 12 hours Sat-Mon and has received fluids and electrolytes 3 times. She has eaten perhaps 2 flakes of soaked hay in this time, and picks at bran or alfalfa mashes. She has produced urine and manure (in reduced quantities, as would be expected, but she pees normally especially after receiving fluids), but she simply is not happy, is eating minimally and drinking almost nothing.
Vet took blood tonight, fingers crossed it gives some guidance because we are stumped. She seems to cycle between looking mostly normal - bright, alert, happy to take a carrot or 2, and completely miserable - lying down, grinding teeth, groaning.
Mare is a very healthy, fit 19 y/o WB with absolutely no previously known health issues.
If anyone has had any experiences with this, would really appreciate hearing from you.
