Overview
Purevax Rabies is a veterinary vaccine used to protect cats from 12 weeks of age against rabies infection. It contains rabies recombinant canarypox virus (vCP65).
The medicine can only be obtained with a prescription.
Purevax Rabies is a liquid suspension for injection under the skin. The first injection should be given in cats aged at least 12 weeks. Protection starts at the latest four weeks after the injection and lasts for a year. The cats should be revaccinated every year.
For more information about using Purevax Rabies, see the package leaflet or contact your veterinarian or pharmacist.
Purevax Rabies is a vaccine. Vaccines work by ‘teaching’ the immune system (the body’s natural defences) how to defend itself against diseases. The vaccine strain vCP65 in Purevax Rabies is a ‘carrier’ canarypox virus that has been given a gene that makes it able to produce part of a rabies virus called ‘glycoprotein G’. The canarypox viruses do not spread or multiply in the cats but they do produce the glycoprotein G of the rabies virus.
When a cat is given the vaccine, the immune system recognises the rabies glycoprotein G as ‘foreign’ and makes antibodies against it. In the future, the immune system will be able to produce antibodies more quickly when it is exposed to rabies, and this helps to protect against mortality due to rabies infection.
A number of studies, including laboratory studies and field trials, were performed in kittens and cats looking at Purevax Rabies used either on its own or together with other cat vaccines, for primary and booster vaccination. The main measure of effectiveness was the ability of the vaccine to trigger immunity against rabies.
The laboratory studies showed that Purevax Rabies can give protection against rabies, and that the protection lasts for up to a year. The field trials showed that the vaccine is safe, and that it triggers a significant increase of anti-rabies antibodies. The vaccine can boost the immune response in cats that have received primary vaccination with another rabies vaccine.
Occasionally, cats will develop temporary slight apathy (loss of interest in surroundings) and mild anorexia (loss of appetite) or hyperthermia (elevated body temperature) lasting for one or two days. There may be a local reaction at the injection site, with slight pain on touching or oedema (swelling) which disappears within one or two weeks at most. For a full list of the side effects reported with Purevax Rabies, see the package leaflet.
