At all our Thrive and Thrive Pet Healthcare network clinics we utilize modern vaccines that are highly safe and effective. As with some human vaccines, there can be minor side effects in pet vaccines that typically disappear with a day or two. These include symptoms like minor redness around the injection site or fatigue. They are completely normal and will not harm your pet long-term.
More severe reactions can occur in a very small percentage of pets who have underlying health problems. It is important to let your veterinarian know of any conditions or prior reactions your pet has had before their vaccination.
For more specific vaccination questions, please consult your local veterinarian.
