Ditto it's the binding agent that can cause a reaction in some horses.
Also, if the area where the horse is injected, isn't cleaned really well, they can develop a bump on that spot. Sometimes it needs lanced by the vet because it won't go away on its own.
Strangles is the most popular vaccine for giving horses a bad reaction. I did them once and will never do them again, so I am not up-to-speed as to whether or not the intranasal form is still better than injectable.
A couple of my horses got the punies from the rabies vaccine this year and they all got the shot in their butts to help avoid a reaction.
The worst was my 24 yr old with serious metabolic issues but, he wasn't bad enough for me to have to call the vet back.
They have never had reactions to WNV, or the 3-way shot.
If you board and are required to pump the horse full of vaccines, don't do them all at once. Spread them out over several weeks; the vet can help you with that decision:)
