Do not vaccinate sick cats.

Do not vaccinate pregnant queens.

Avoid stress around the time of vaccination.

Local injection site reactions such as swelling, pain, pruritis or hair loss may occur post vaccination. A small percentage of vaccinated cats may also develop post vaccination reactions such as fever, vomiting, anorexia and lethargy.

Hypersensitivity reactions such as urticaria or facial oedema, sometimes accompanied by respiratory signs have been reported.

In the event of an allergic reaction, immediate treatment should be given using epinephrine (adrenaline) intramuscularly and/or a short acting glucocorticoid (eg dexamethasone sodium phosphate) intravenously.

Animals that have received immunosuppressive drugs should not be vaccinated until an interval of at least 4 weeks has elapsed.

No information is available on the safety and efficacy from the concurrent use of this vaccine with any other product except Katavac CHP or Eclipse IV provided that these two vaccines are authorised. It is therefore recommended that no other vaccines than these should be administered within 14 days before or after vaccination with the product.

Vaccination has no known beneficial effect in cats already infected with FeLV. Therefore, diagnostic testing of cats for the presence of feline leukaemia (FeLV) core protein p27 in serum prior to vaccination may be advisable.

In any population there will be a small number of individuals that shows no or only a slight immunological response to the vaccination. Successful vaccination depends upon correct storage and administration of the vaccine and the animal's ability to respond. The immunological response may be influenced by hereditary factors, intercurrent infection, subclinical infection, age, nutritional status, concurrent drug therapy, stress, etc.
