Vaccines are available for a number of important infectious diseases in cats. It is generally recommended that all cats be vaccinated against the viruses causing cat flu, panleucopenia virus (or feline parvovirus), and rabies (in countries where this is a problem) due to the severity and/or frequency of infection with these viruses. It is commonly recommended that all kittens also receive vaccination against feline leukaemia virus. Other vaccines are also available, but their use will depend on the lifestyle and risks of the individual cat.
Generally kitten vaccines are started around 8 to 9 weeks of age, with a second injection around 3 to 4 weeks later. A final kitten vaccination at 16 to 20 weeks may also be recommended. A booster vaccination is given a year later. After this, vaccination needs should be assessed at least once a year. Which vaccines are used and the frequency of their use will vary according to individual circumstances, and this should be discussed with your vet. Remember too, that while vaccination can never provide 100% protection in all situations, vaccines play an absolutely vital role in the fight against these feline diseases.
