At What Age Should I Get My Kitten Vaccinated?

One of the joys of life is the arrival of a new kitten. Their little paws, inquisitive whiskers, and lively temperament are enough to capture the heart of anybody. With the purrs and with the cuddles, however, goes a very real duty: keeping your new friend safe with proper vaccination.
Kitten vaccination isn’t just a vet recommendation – they’re your cat’s protection from devastating, potentially life-threatening disease. Understanding when and why to vaccinate may be the difference between a healthy, well-adjusted feline and costly future medical emergencies.
Learning About Your Kitten’s Vaccination Schedule
The timing is particularly important with a kitten injection. The immune system of the kitten develops over time, and the vaccines work best when given at timed intervals.
First Immunisations: 6-8 Weeks
Your kitten receives early vaccinations. Core vaccinations are provided to kittens at 6-8 weeks of age. They protect your kitten from the most prevalent and severe cat illnesses: feline panleukopenia (feline distemper), feline herpesvirus, and feline calicivirus.
These kittens have some residual immunity from their mum, but it’s fading. The first vaccine makes up the gap and starts building your kitten’s own immunity.
Second Round: 10-12 Weeks
The second vaccine is at 10-12 weeks. The booster is provided to enhance immunity and have your kitten well protected. Your veterinarian also administers the rabies vaccine during this time, but timing varies depending on local statute and your veterinarian’s policy.
16 Weeks: Final Kitten Vaccination
The third and final kitten vaccination is around 16 weeks of age. This is when all the maternal antibodies will have passed out and your kitten’s immune system will be able to react to the immunisations to the best of its ability. This final series gives maximum immunity as your kitten matures.
Personalising Vaccines to Your Kitten’s Lifestyle
Not all kittens need the same vaccinations. Lifestyle comes into play as to whether other vaccinations might be needed for your cat.
Indoor cats
If your kitten is to be an indoor cat, they will have fewer opportunities for disease exposure. Core vaccinations are still needed, though. Indoor cats still have a chance to be exposed to viruses, through open windows, on your clothing, or in emergency trips to the vet.
Outdoor Access
Outdoor kittens need additional protection. Your veterinarian will probably recommend FeLV vaccination, which is passed on by contact with an infected animal. Outdoor cats are also at greater risk of rabies, so this vaccine is particularly important.
Multi-Cat Households
Multi-cat households pose a specific issue. If you are bringing in a kitten to a household where there already reside cats, keeping all the animals up to date on vaccinations will protect everyone. Your vet can suggest the most gradual introduction schedule.
The Real Cost of Staying Unvaccinated
It’s a question that some kitten owners pose: do vaccines have to be given? The diseases vaccines guard against are not just serious—but catastrophic.
Cat panleukopenia is a lethal immune system threat and is always fatal, particularly so in kittens. Feline herpesvirus causes chronic respiratory and eye disease. Rabies is typically always fatal following the appearance of signs.
They are expensive, stressful, and in some cases unsuccessful to cure. Prevention by immunisation is cheaper and better than treating a disease that can be prevented.

Creating Your Kitten’s Health Plan
Each kitten is unique, and so must be the vaccination schedules. Your veterinarian will consider your kitten’s lifestyle, health, and risk of disease in your area when drawing up an individualised vaccination schedule.
Don’t wait to have this conversation. Call your local veterinary clinic soon after you bring your kitten home. Vaccinating your pet early will not only keep your pet safe, but it will also begin a relationship with a veterinary team that will be taking care of your cat for the rest of their life.
Your kitten is counting on you for protection that they cannot provide themselves. One of the most important things that you can do for your new friend is vaccination.
