Does anyone’s cat experience vaccine reactions?

My cat is severely allergic to vaccines. The first time he was given vaccines he got stiff and start to shut down. The vet had to detox him. He has to be sedated for his violent behavior and be given a Benadryl shot between each series of shots so he won’t have a reaction. That is why I am not vaccinating him... show more My cat is severely allergic to vaccines. The first time he was given vaccines he got stiff and start to shut down. The vet had to detox him.
