What should you know about non-adjuvanted rabies vaccine for cats?

Rabies is a serious infection that can spread through the saliva of an infected mammal, usually through a bite. Vaccination reduces the risk for the cat and helps protect people who live with or handle it.

An adjuvant is an added ingredient intended to strengthen or prolong the immune response to a vaccine. A non-adjuvanted product does not contain that added ingredient. The vaccine can still train the immune system to recognise rabies virus, and the product must still be authorised for cats.

The formulation is only one part of the decision. Your veterinarian also considers the cat’s age, health, previous vaccination history, travel or outdoor exposure, and local rules. Different products are not automatically interchangeable, so keep the product name and vaccination record.

After vaccination, mild soreness, tiredness, or a temporary reduction in appetite can occur. A small swelling at the injection site should be checked if it persists, changes, or concerns you. A cat with breathing difficulty, facial swelling, collapse, or repeated vomiting needs urgent veterinary attention.

Arrange the appointment with a veterinary clinic and share the cat’s medical history, current medicines, prior vaccine reactions, and any recent illness. Ask which rabies product is licensed for cats and when the next dose is due.

The clinic should assess the cat before vaccination and give the product according to its label. Do not use a vaccine intended for another species or obtain a dose that has not been stored and handled by the clinic.

For the rest of the day, watch for changes in behaviour, eating, breathing, and the injection site. Follow the clinic’s advice about activity and follow-up. Keep the certificate or record, especially if the cat may travel, board, or enter a regulated setting.

Contact a veterinarian promptly if the cat develops facial swelling, hives, difficulty breathing, severe weakness, collapse, or repeated vomiting after vaccination. These signs can indicate a serious reaction and should not be watched at home.

If a cat is bitten or scratched by a bat, stray animal, or mammal acting unusually, separate the animals safely and call a veterinarian immediately. Avoid touching saliva or handling the injured animal with bare hands. Do not wait for symptoms: rabies can be fatal once illness develops.

Anyone bitten, scratched, or exposed to saliva should wash the area with soap and running water and seek urgent medical advice. A clinician can decide whether rabies post-exposure care is needed; the cat’s vaccination record will be relevant.

Ask: Is this non-adjuvanted product authorised for cats, and why is it suitable for my cat? What schedule applies to this dose? How should I monitor a previous vaccine reaction or an existing health problem? What should I do if the cat is exposed to a possibly rabid animal?
