When should kittens be vaccinated and against what diseases? - in detail
Kittens should begin their vaccination schedule at around 6 to 8 weeks of age, as this is when the maternal antibodies they receive from their mother’s milk start to wane, leaving them vulnerable to infections. The core vaccines, which are essential for all kittens regardless of their environment or lifestyle, include those for feline panleukopenia (also known as feline distemper), feline herpesvirus (which causes upper respiratory infections), feline calicivirus (another cause of respiratory disease), and rabies. Feline panleukopenia is a highly contagious and often fatal disease, while herpesvirus and calicivirus are major contributors to respiratory and oral health issues in cats. Rabies, a deadly zoonotic disease, is often required by law in many regions due to its public health significance.
The initial vaccination series typically involves multiple doses administered at 3- to 4-week intervals until the kitten is around 16 weeks old. This ensures adequate immune system stimulation and protection. For example, the first dose of the feline panleukopenia, herpesvirus, and calicivirus vaccine is given at 6 to 8 weeks, with boosters at 10 to 12 weeks and 14 to 16 weeks. Rabies vaccination is usually administered once, at 12 to 16 weeks of age, depending on local regulations. Non-core vaccines, such as those for feline leukemia virus (FeLV), may be recommended based on the kitten’s risk of exposure, particularly if they will spend time outdoors or live in multi-cat households. FeLV is a serious disease that weakens the immune system and increases susceptibility to other infections.
After the initial series, booster vaccinations are necessary to maintain immunity. For core vaccines, boosters are typically given one year after the initial series and then every one to three years, depending on the vaccine type and local guidelines. Rabies boosters are often required annually or every three years, depending on the vaccine used and regional laws. Regular veterinary consultations are essential to tailor the vaccination schedule to the kitten’s specific needs and to ensure they are protected against preventable diseases throughout their life.
