VACCINATIONS

 

Cats are currently routinely vaccinated against Cat flu (herpes virus and calicivirus), Feline Enteritis (panleucopaenia)
and Feline Leukaemia Virus. All these vaccines are carried out annually except feline enteritis
which is carried out every 3 years.

 

What we vaccinate against

 


Cat Flu

Cat flu is caused mainly by either herpes virus, calicivirus or both although sometimes other viruses and bacteria may contribute to the symptoms seen. The problem is most commonly seen in kittens and can be fatal in the most severe cases. Much of the problem lies in the chronic effects of contracting these viruses. Calicivirus may cause chronic gum disease but the main concern is herpes virus which stays in the body and reactivates especially at times of stress, in a similar way to cold sores in people.

 

Feline Herpes

Herpes virus is the commonest cause of recurrent conjunctivitis in cats and is also a cause of chronic recurrent sneezing (rhinitis). If a cat has previously suffered from cat flu it is still considered worthwhile vaccinating to try to maintain good immunity and prevent recurrences.


Feline Enteritis
Feline Enteritis is caused by a virus similar to parvovirus in dogs. It can cause brain damage in kittens as well as severe, often fatal, diarrhoea. Thankfully, vaccination has largely brought the condition under control and confirmed cases are now quite rare. Thus the vaccination is now given only every 3 years.
 

 

Feline Leukaemia
Feline Leukaemia Virus is blood-borne and therefore is much more commonly seen in cats that fight (especially stray Toms). If cats are to be kept indoors or are in a confined garden then there is little need to vaccinate against this. The virus itself, when contracted, may only cause mild fever and may go un-noticed but it has many chronic effects predisposing cats to various types of cancers, anaemia and immune problems. Anaemia and immune problems may also arise secondary to FIV (feline immunodeficiency virus). This disease is also blood borne but there is currently no vaccination available to protect against this disease.

 

Chlamydia

A vaccine is also available against Chlamydia, another cause of conjunctivitis. In view of the relatively easily treatable nature of this condition we do not include this in our core vaccines.

 

 

Concerns on Vaccinations

As vets we are regularly asked as to whether vaccinations are necessary. This has come about due to the decreased incidence of many diseases as a result of vaccination but also due to health concerns about over-vaccination.

Whilst it is right to question the frequency of vaccination there is no doubt that there is a genuine need for vaccination as a concept and it is our belief that alternatives such as homeopathic nosodes are of little, if no benefit. The vaccination company that we use (Nobivac) has a good reputation for decreasing the frequency of vaccination where the evidence shows that we can do so safely.

We, as  vets, are also guided by independent bodies such as the British Small Animal Veterinary Association. Nobivac recently carried out a large, nationwide study of the development of diseases such as epilepsy and skin problems between the vaccinated and unvaccinated populations. There was no statistical difference in the development of chronic medical conditions between the vaccinated and unvaccinated population, suggesting that vaccination should not be implicated as a trigger factor for these diseases.

That is not to say that vaccination cannot have side effects. Individual animals may react badly to an individual vaccine and its use again would have to be carefully considered. There is one known and well-recognised condition that cats get on the back of their necks. This is an injection-site sarcoma, a type of tumour, which appears to be related to repeated injections (vaccinations or other) at this site. If we suspect this we would offer prompt surgical intervention.

On the whole, however, we believe that the benefits of vaccination far outweigh the risks. If you have any specific concerns, however, one of the vets will gladly discuss this further with you
