QUESTION 🙋🏻♀️
Yesterday I had 15 horses vaccinated with their annual boosters for flu/flu tetanus.
Today I have 10 of the 15 horses with high temperatures (above 38.5 degrees) and generally feeling pretty rubbish.
It’s not the first time I’ve seen flu vaccine reactions, had them before over the years with a temp and sore around the vaccination site/stiff neck but 10 out 15 horses, that’s madness!
Has anyone else experienced anything like this before but more so with larger number of horses?
Spoken with my vets and the vaccine company will be contacted but just seems really odd 🤔
