Feline Vaccine Schedule

The feline vaccine schedule is a critical component of preventive care for cats, designed to protect them from serious and potentially life-threatening diseases. As a veterinarian with over a decade of experience in feline medicine, I have seen firsthand the importance of adhering to a well-structured vaccination program. In this article, we will delve into the details of the feline vaccine schedule, exploring the various types of vaccines, their recommended administration timelines, and the factors that influence vaccination decisions.
Understanding Feline Vaccines

Feline vaccines are biological preparations that stimulate the cat’s immune system to produce a protective response against specific diseases. There are two main categories of feline vaccines: core vaccines and non-core vaccines. Core vaccines are considered essential for all cats, as they protect against highly infectious and potentially fatal diseases such as panleukopenia, calicivirus, and rhinotracheitis. Non-core vaccines, on the other hand, are recommended based on a cat’s lifestyle, geographic location, and individual risk factors.
Core Feline Vaccines
The core feline vaccines include:
- Panleukopenia (also known as feline distemper)
- Calicivirus
- Rhinotracheitis (caused by the feline herpesvirus)
These vaccines are typically administered in a combination vaccine, often referred to as the FVRCP vaccine (feline viral rhinotracheitis, calicivirus, and panleukopenia). The initial series of core vaccines is usually given to kittens at 6-8 weeks of age, with boosters administered every 3-4 weeks until the kitten is 16-17 weeks old.
Vaccine Type | Initial Administration | Booster Schedule |
---|---|---|
FVRCP | 6-8 weeks | Every 3-4 weeks until 16-17 weeks old |

Non-Core Feline Vaccines

Non-core vaccines are recommended based on a cat’s individual risk factors, such as outdoor exposure, travel history, or exposure to other cats. The most common non-core feline vaccines include:
- Feline leukemia virus (FeLV)
- Feline immunodeficiency virus (FIV)
- Feline infectious peritonitis (FIP)
These vaccines are typically administered to cats that are at high risk of exposure to these diseases, such as outdoor cats or cats that are exposed to other cats that may be infected.
Vaccine Administration and Boosters
The administration of feline vaccines and boosters is critical to ensuring the development of adequate immunity. The initial series of core vaccines is usually given to kittens, with boosters administered every 3-4 weeks until the kitten is 16-17 weeks old. Adult cats typically require booster vaccinations every 1-3 years, depending on the type of vaccine and the cat’s individual risk factors.
Key Points
- Core feline vaccines include FVRCP (feline viral rhinotracheitis, calicivirus, and panleukopenia)
- Non-core vaccines are recommended based on individual risk factors, such as outdoor exposure or travel history
- Initial vaccination series is typically given to kittens at 6-8 weeks of age, with boosters administered every 3-4 weeks until 16-17 weeks old
- Adult cats require booster vaccinations every 1-3 years, depending on the type of vaccine and individual risk factors
- Consult with a veterinarian to determine the best vaccination schedule for your cat based on their individual needs and risk factors
In conclusion, the feline vaccine schedule is a critical component of preventive care for cats, and adherence to a well-structured vaccination program is essential for protecting cats from serious and potentially life-threatening diseases. By understanding the different types of feline vaccines, their recommended administration timelines, and the factors that influence vaccination decisions, cat owners can work with their veterinarians to ensure their cats receive the best possible protection against infectious diseases.
