What vaccine should a cat have first? - in detail
When it comes to vaccinating a cat, the first vaccine administered is typically the core vaccine for feline panleukopenia, also known as feline distemper. This highly contagious and potentially fatal viral disease affects a cat’s immune system, gastrointestinal tract, and nervous system. Kittens are particularly vulnerable to this virus, which can spread rapidly through direct contact with infected animals or contaminated environments. The feline panleukopenia vaccine is often combined with vaccines for feline herpesvirus and feline calicivirus, which are also core vaccines. These three viruses are responsible for the majority of upper respiratory infections in cats and can lead to severe illness if left untreated. The initial vaccination schedule for kittens usually begins at around 6 to 8 weeks of age, with booster shots given every 3 to 4 weeks until the kitten reaches 16 weeks of age. This ensures adequate protection as maternal antibodies, which are passed from the mother to the kitten, gradually wane. Adult cats with an unknown vaccination history should also receive this vaccine, followed by a booster after 3 to 4 weeks. After the initial series, the vaccine is typically administered every 1 to 3 years, depending on the veterinarian’s recommendation and the cat’s lifestyle. While non-core vaccines, such as those for feline leukemia virus or rabies, may also be necessary depending on the cat’s environment and risk factors, the feline panleukopenia vaccine is universally recommended as the first and most critical step in protecting a cat’s health.
