Although it is uncommon, vaccine reactions can occur. We want you to be aware of some of the vaccine reactions that pets can experience. These reactions can range from very mild to severe. They usually occur within one hour of receiving a vaccine, but reactions can be delayed by several hours. Vaccines may also cause a lump at the injection site. If this lump lasts longer than a week, let us know.
Any vaccine can be associated with a reaction. The vaccines that have been associated with reactions are the following:
