Typical vaccine reaction is a slight temperature, soreness, vomiting and very lethargic. It sounds like Minnie might of had a mild vaccine reactions if he symptoms started right after the vaccine. However if she was vaccinated days before this started it is unlikely they are related. I would recommend taking her back to the vet for a good exam to make sure she does not have something more serious going on like a virus or infection. She might need some medications to help resolve her issues. hope that helps
