Cats need vaccines according to their age and lifestyle risk, with different schedules for kittens and adult cats: Kittens:

• First vaccination typically at 6 to 8 weeks old.
• Booster doses every 3 to 4 weeks until 16 to 20 weeks of age.
• Full protection is usually achieved 7 to 10 days after completing the series.
• Common vaccines include FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia), rabies, and feline leukemia virus (FeLV) depending on risk factors

Adult Cats:

• After completing kitten series, a booster is given one year later.
• Subsequent boosters are given every 1 to 3 years, depending on the cat's lifestyle and exposure risk.
• Indoor or low-risk cats may receive core vaccines every three years.
• Cats at higher risk (e.g., outdoor cats, multi-cat households, or cats visiting catteries) may need annual boosters.
• Rabies vaccine frequency may be annual or every three years depending on local regulations and vaccine type

Veterinarians tailor vaccination schedules based on individual risk assessments, considering factors like age, medical history, environment, and exposure likelihood. Discussing your cat’s lifestyle with your vet is essential to determine the optimal vaccination frequency

. In summary, kittens need multiple vaccines in their first few months, while adult cats typically require boosters every one to three years, with annual boosters recommended for higher-risk cats.
