Side Effects of Flu/Tet Vaccination?

[Vezbo]

Hi all,
Have recently moved to a new area and registered with the local Equine practice.
They came out last night at 8pm to give my 13yo 15.2hh TBxID a straightforward Flu/Tet jab and everything seemed normal.
I arrived at the yard @ 2pm this afternoon, and was horrified to find my horse in the paddock, on his feet, but almost unable to move. I managed to get him very slowly back to the yard, he was unstable, in clear discomfort, and unable to extend his neck to graze or drink.
I called the practice again as I was so worried, the response was excellent and the same vet came out within a few hours. He advised his temperature was .5 higher than usual, administered a muscle relaxant and advised x2 Bute morning and evening for the next few days.
I left the yard at 9pm tonight and he is still no better, and unable to even drink from his water bucket so I have had to tie his buckets at nose height in the stable. Other than this he has managed a feed and an apple, is picking at his hay but is definitely withdrawn and out of character, and is just standing in his box quietly.
Has anyone ever experienced such a severe reaction like this before?
I have never come across this in all the 8 years I have owned the horse and it has really worried me.

I'd be more worried that he's done something neurological from titting about in the field overnight. I'd guess that at 13yrs old, he's had plenty of flu/tet jabs so doubt if it's that.

Well I don't know what to think, the vet seemed to think likely cause was a reaction as although fairly rare, apparently it can and does happen. He also thought it was too much of a coincidence to have happened the next day so must be related, but as you say, I am also very concerned that he has done something more physical. However, other extremely experienced people on my yard say they have seen these side effects happen before and that it is normal.

two of our TB's have the flu and tet in their bums now as they reacted badley to the ones in the neck

they could not stretch down for eating or drinking and had slightly raised lumps on their necks from the jabs

it lasted around 3 days and they were also quiet within themselves

bute was given until they seemed better in themselves

Not this year but last year, 3 horses on our yard, mine included had a bad reaction to their flu/tet vacc.
V high temperature, head hung low, reluctant to move. Mine ate her hard feed and drank but wasn't interested in her haylage.
She was fine in a couple of days. I spoke to the vet and he said as long as she was drinking and not getting dehydrated he wasn't too worried.

This year, I asked for a different vaccine manufacturer and she was fine .

I hope yours is feeling better today.

Thank you horsedreams & quirky, I am so relieved to hear that other people have experienced a similar thing.

He's still quiet this morning and barely touched his water throughout the night (even though I have put buckets at nose level) but managed most of his haynet. He did have slightly more movement which was a good sign.

Gave him a feed with 1x bute, and within half an hour or so he was trying to stretch a little more so it must have been starting to take effect.

Turned him out and although he is struggling to graze, he is managing to get down there just about and can now reach the water trough, must have been feel pretty thirsty have seen him drink at least 4 times already this morning.

Am feeling a lot happier now than I did last night, and so is he I should think!

Really appreciate the replies, thanks x

My mare has been very sore the last few times she has had her jags. It seems to be worse when it is both flu and tet. I've had her for longer and it was fine before. First time she had a reaction, I only realised when I gave her evening feed and she just stood there and looked at me - poor girl couldn't get her head down far enough and I had to raise the bucket for her.

Warned the vet next time and he jagged her chest instead of neck. The side he injected came up in a big lump - seemed to be fluid but I didn't poke too much for obvious reasons.

Was searching this evening cos she just had this year's jags (in chest again) and is clearly feeling quite sorry for herself. Jags were mid morning - she was find midday. But by 4pm she was walking very carefully, and at one stage was shaking all over

She was checked again for me at around half six and seemed happier but had put herself into the shelter (they have free access). This is a different kind of reaction to that I have seen before. Poor wee girl
