It is common for pets to experience mild side effects after receiving a vaccine, usually starting within hours of the vaccination. If the following side effects last for more than a day or two – or if they cause your pet significant discomfort – it is important for you to contact your veterinarian:
• Discomfort and local swelling at the vaccination site
• Mild fever
• Decreased appetite and activity
Sneezing, mild coughing, “snotty nose,” or other respiratory signs may occur 2-5 days after your pet receives an intranasal vaccine. More serious, but less common side effects, such as allergic reactions, may occur within minutes to hours after vaccination. These reactions can be life-threatening and are medical emergencies.
Seek veterinary care immediately if any of these signs develop:
• Persistent vomiting or diarrhea
• Itchy, hive-like bumps on the skin
• Swelling of the muzzle and around the face, neck, or eyes
• Severe coughing or difficulty breathing
A small, firm swelling under the skin may develop at the site of a recent vaccination. It should start to disappear within a couple of weeks. If it persists more than three weeks or seems to be getting larger, you should contact your veterinarian. Always inform your veterinarian if your pet has had prior reactions to any vaccine or medication and when in doubt, wait for 30-60 minutes following vaccination before taking your pet home.
