Vaccination & Immunization

Vaccination is one of the most important steps in protecting kittens from serious and potentially fatal diseases. During early life, a kitten’s immune system is still developing, making timely vaccination essential for building strong, long-term immunity.

Veterinary organizations such as the American Veterinary Medical Association (AVMA) and the World Small Animal Veterinary Association (WSAVA) recommend a structured vaccination schedule for all kittens.

Core Vaccines for Kittens

Core vaccines are recommended for all kittens, regardless of lifestyle.

FVRCP (Combination Vaccine)

Protects against:

  • Feline Viral Rhinotracheitis (Herpesvirus)
  • Calicivirus
  • Panleukopenia (Feline Distemper)

These diseases are highly contagious and can be severe, especially in young kittens.

Rabies

  • Required by law in many regions
  • Protects against a fatal disease that can affect both animals and humans
  • Typically given around 12–16 weeks of age

Non-Core Vaccines

Depending on lifestyle and risk, veterinarians may recommend:

  • Feline Leukemia Virus (FeLV) – for outdoor or multi-cat households
  • Chlamydia felis – in high-risk environments
  • Bordetella – in shelters or group housing

These vaccines are given based on individual risk assessment.

Kitten Vaccination Schedule

A typical schedule may include:

Age (Weeks) Vaccines
6–8 First FVRCP
10–12 Second FVRCP
14–16 Final FVRCP + Rabies
12–16 FeLV (if recommended)

Booster shots are usually given at 1 year, then every 1–3 years depending on vaccine type.

Vaccine Safety

Vaccines are generally safe and well-tolerated.

Mild side effects may include:

  • Temporary tiredness
  • Slight swelling at injection site
  • Mild fever

Severe reactions are rare but require immediate veterinary care.

Preparing for Vaccination

  • Ensure your kitten is healthy before vaccination
  • Bring medical records to the appointment
  • Monitor your kitten after vaccination
  • Follow your veterinarian’s recommended schedule
