Why are cats revaccinated? - briefly
Cats are revaccinated to maintain their immunity against diseases, as the protective effects of vaccines diminish over time.
Why are cats revaccinated? - in detail
Cats are revaccinated to ensure sustained immunity against infectious diseases throughout their lives. Vaccines stimulate the immune system to produce antibodies that protect against specific pathogens. However, the effectiveness of these antibodies can diminish over time, leaving cats vulnerable to infections. Revaccination, also known as booster shots, helps replenish and maintain adequate levels of protective antibodies. The duration of immunity varies depending on the vaccine type, the cat’s age, health status, and environmental factors. Core vaccines, such as those for feline panleukopenia, feline herpesvirus, and feline calicivirus, are typically administered in a series during kittenhood and followed by periodic boosters. Non-core vaccines, like those for feline leukemia virus or rabies, are given based on the cat’s risk of exposure. Veterinarians tailor revaccination schedules to individual cats, considering factors such as lifestyle, geographic location, and medical history. Over-vaccination is avoided by adhering to evidence-based guidelines, which balance the need for protection with minimizing potential adverse effects. Regular revaccination not only safeguards individual cats but also contributes to herd immunity, reducing the spread of diseases within the feline population.
