Hello, sorry to hear about Benita. She may be having an allergic reaction to the vaccine. These may be mild to severe reactions. If she continues to tremble, develops vomiting, or becomes lethargic then she should be seen by your veterinarian back immediately. She may need allergy medications or even an injection of steroids to control her allergic reaction. Hope this helps and best of luck.
