Vaccination is one of the most important tools for preventing serious diseases in companion animals. Understanding how vaccines work and why timing matters can help you make informed decisions about your pet's preventive care program.
Core vs. Non-Core Vaccines
Veterinary organizations classify vaccines into two main categories based on disease risk and severity:
Core vaccines protect against diseases that are severe, widespread, or transmissible to humans. These are recommended for all pets of a particular species regardless of lifestyle. For dogs, core vaccines include DHPP (Distemper, Hepatitis, Parvovirus, Parainfluenza) and Rabies. For cats, core vaccines include FVRCP (Feline Viral Rhinotracheitis, Calicivirus, Panleukopenia) and Rabies.
Non-core vaccines are recommended based on individual risk factors including geographic location, lifestyle, and exposure potential. Examples include Bordetella and Lyme disease vaccines for dogs, and Feline Leukemia (FeLV) vaccine for cats at risk of exposure.
Puppy and Kitten Vaccination Series
Young animals receive a series of vaccinations because maternal antibodies can interfere with vaccine effectiveness. The series ensures protection as maternal immunity wanes, typically starting around 6-8 weeks of age and continuing every 3-4 weeks until 16-20 weeks of age.
During this vaccination series, it's important to limit exposure to unvaccinated animals and high-risk environments while still providing appropriate socialization opportunities. Your veterinarian can provide specific guidance based on your area's disease risk and your pet's vaccination status.
Adult Vaccination Schedules
After completing the initial series, adult pets typically receive booster vaccines annually or every three years, depending on the specific vaccine and risk factors. Some vaccines, like rabies, have legally mandated intervals that vary by location.
Recent veterinary research has led to more individualized vaccination protocols. Your veterinarian may recommend antibody testing (titers) for some diseases to determine if booster vaccination is needed, particularly for pets with health concerns or previous vaccine reactions.
Working with Your Veterinarian
The best vaccination schedule for your pet depends on multiple factors including age, health status, lifestyle, and local disease prevalence. Regular discussions with your veterinarian ensure your pet receives appropriate protection while avoiding unnecessary vaccines.
Keep accurate vaccination records and bring them to all veterinary visits. If you move or change veterinarians, these records help ensure continuity of care and appropriate timing of future vaccinations.
