What are some effects we would notice after pet being vaccinated?
Some pets can have mild soreness or be sleepy and lethargic for 12 – 24 hours. Any vomiting, diarrhea, or difficulty breathing warrants a call to our office (Cornell Animal Hospital or Colonial Veterinary Hospital if after hours). Less common but possible vaccine reactions include hair loss at vaccine site and vaccine-induced sarcomas in cats. If your pet has a lump on their leg following vaccination that does not go away after a few weeks, it should be evaluated by your veterinarian.
