Hi I almost lost my little Teasell thanks to vaccinations. She now has issues pretty much with all of them including Rabies vacines. Thank goodness my Veterinarian has stated we will find a way not to give her any vaccine she really doesn't need. May have to apply for a waiver from the Rabies vaccine though she isn't due for one for next 3 years...
My thought is even if they have meds like Benedryl on board they still may have some sort of chemical problem.
I do know that before she had these reactions she never scratched or acted like she was itching and now we have issues with that.
