Non-Core Feline Vaccinations

Some feline vaccinations are given on a case by case basis; these are commonly referred to as non-core vaccines.  Non-core feline vaccinations include a group of vaccines that may not be appropriate for some cats due to the low risk of an infection.  Non-core feline vaccinations include the feline bordetella vaccine, feline giardia vaccine, feline immunodeficiency vaccine, feline leukemia vaccine, and the feline infectious peritonitis vaccine.  These vaccines are given based on the possibility of the cat becoming infected with the corresponding disease.

Feline leukemia as well as feline immunodeficiency virus occurs most frequently with cats that live outdoors and socialize, or get involved in altercations with other cats.  Cats that are outdoors should be vaccinated against these viruses. Cats that live indoors and have no risk of exposure do not need these vaccines.  A blood test should be conducted before a vaccine to prevent feline leukemia or feline immunodeficiency virus is given to a cat.  Only cats testing negative should be vaccinated against these diseases.

Feline leukemia vaccines are given to kittens between the ages of 8 to 12 weeks.  A booster is given 3 to 4 weeks later.  Thereafter, a feline leukemia booster should be given on an annual basis.

FIV vaccinations are available, but do not provide one hundred per cent protection.  Cats that stay indoors and do not have contact with those who go outdoors do not need to get the FIV vaccine.

Cats should only receive feline Bordetella (kennel cough) vaccines if they are going to be living in an environment where the disease previously existed, such as a cattery or shelter facility.  Bordetella is not usually necessary for household cats.

Chlamydia is another vaccine which should only be given to cats placed in an environment where the disease previously existed.

The feline giardia vaccination is sometimes used as a curative agent in cats which are already infected with giardia.  Thoughts on its use as a preventative are variable.
