Local Vaccine Reactions MONTHS After Injection?

I am just asking if this is usual to inject in the hindquarters. We don’t have as many vaccines as you do over there, however we vaccinate in the neck.

I use the neck, pectoral region, and hamstrings for vaccines, but not the croup/gluteal region.
Drainage there in the event of an abscess is a PIA, so I reserve it for antibiotics.

Vaccine reactions occur within 48 hours.

Very common here, unless the horse is a performance horse, and even sometimes then. Croup and chest for vaccines, and the only needle in the neck is for EIA Coggins testing.

I don’t vaccinate in the neck anymore. I’ve seen too many reactions in that location on horses with no history of adverse reactions.

I’m not sure what that is. We are in the Midwest, not sure if that’s why. We see “normal” strangles and bastard strangles. I’ll do some research!

I just did a quick Google search. Dryland/False Strangles is a slang term for Pigeon Fever. We do not call it anything but Pigeon Fever here which is why I was confused.

The very same vet that drained and assessed these abscesses has also cultured a possible Pigeon Fever case, but it’s over 40 miles away from this facility. This is also very far from the “normal” presentation of PF. The abscesses are blowing out on their croups, not their chests, and it’s only been one per horse.

Pecs or hamstrings for just about anything that doesn’t go in the vein. Neck and croup reactions are no fun.

And personally, from all the vaccinating and repro injections I did over the years on dairy cattle, I always choose hamstrings if at all possible. I find that cows and horses just really don’t care much about a “bug bite” on the back of the hind leg. I did “drive bys” for years on cattle - wade into the herd with a pocket full of readied injections and just poke, poke, poke. Calves might occasionally take a little leap forward, but that was about it.

The one time I had an immediate reaction in a close up (due to calve soon) cow, I was very glad I was nowhere near her front end and she wasn’t tied up as it was a neurological reaction to selenium. Called the vet, “Oh yes, that can happen. It’s pretty rare, but it’s definitely a thing.” I was super careful with selenium injection after that, let me tell you.
