Common Side Effects of Cat Vaccinations Explained

1. Allergic Reactions: Cats with immune allergies may experience reactions shortly to a few hours after vaccination. Symptoms can include pale gums, drooling, cold limbs, rapid heart rate, weak pulse, lethargy, vomiting, sudden diarrhea, shock, seizures, and coma. If an allergic reaction is confirmed, it's crucial to seek veterinary care immediately for an adrenaline shot.

2. VaccineAssociated Sarcomas: Fibrosarcomas are a type of connective tissue sarcoma, often linked to local allergic reactions to vaccines, particularly those for leukemia. Therefore, it's not advisable to vaccinate cats against leukemia if they haven't been exposed to the virus. These tumors typically appear as lumps three months postvaccination, with a diameter greater than two centimeters, and they can grow over time.

3. Discomfort or Swelling at the Injection Site: Cats may experience pain or swelling at the vaccination site, which usually occurs within 30 minutes to a week after vaccination. Occasionally, cats may develop abscesses at the injection site, accompanied by mild fever, decreased appetite, and reduced activity. However, these symptoms often resolve on their own without the need for specific treatment.

4. Lame Syndrome: Three weeks after receiving a weakened virus vaccine, cats may develop this condition. Lame syndrome is caused by muscle pain and often comes with symptoms like fever, drowsiness, loss of appetite, and depression. Full recovery typically takes about 24 to 48 hours. In severe cases, antibiotics or painkillers may be necessary.

5. Birth Defects: If a cat receives a weakened virus vaccine while pregnant, it may lead to miscarriage or the birth of kittens with defects. Therefore, pregnant cats should not be vaccinated to avoid tragic outcomes. It's also important to ensure your cat is in good health before administering any vaccinations.

While it's true that vaccinations can lead to adverse reactions in cats, this doesn't mean that skipping vaccines is the best option. Without vaccinations, cats are at risk of contracting many infectious diseases.
