Your cat, just like you, needs to be administered vaccines in order to prevent the contracting of infectious diseases. Immunisation is one of the most effective ways to protect your cat against the most serious infectious diseases.
Existing feline vaccination guidelines are designed by experts, such as from the World Small Animal Veterinary Association (WSAVA), so that each animal is provided with adequate protection against the diseases which can attack at any point in its life. It is important to strictly follow these guidelines in order to ensure maximum effectiveness and immunise against certain viral and bacterial threats that can be very serious. If recommended intervals are not observed, the effectiveness of the protection may diminish and the cat would be at risk, so it may be necessary to begin vaccinations anew.
You should consult your veterinarian as immunisation schedules may vary for the first administration and other vaccinations may be recommended in addition to the basic ones.
When to receive them
In general, kittens should not be vaccinated before 8-12 weeks of age, as they still keep high levels of antibodies (that have been transferred by their mother through the colostrum) in their blood, so the effect of any vaccine could wear off. However, each individual case must be assessed by a veterinarian to determine the ideal age to begin vaccinating a kitten.
Major veterinary associations have drawn up some general recommendations on ages and intervals for each vaccination, but ultimately the veterinarian will be the one to customise a calendar for each cat. It is always recommended to complete a deworming before beginning to vaccinate a kitten, so that its immune system can properly respond to vaccines.
