Vaccination Schedule for Puppies and Kittens (2026 Guide)
Vaccinations are one of the most important preventive care measures for young pets. According to the World Small Animal Veterinary Association (WSAVA), puppies and kittens should start their core vaccination series no earlier than 6 weeks of age, with revaccination every 3-4 weeks until 16 weeks. This comprehensive guide covers the 2026 recommended schedules based on current veterinary guidelines.
Why Puppies and Kittens Need Multiple Vaccines
Very young animals are highly susceptible to infectious diseases because their immune systems are not yet mature. Puppies get some protective immunity against infections from their mothers at birth and through her milk. Vaccines won't work well until this maternal immunity fades, which is why puppies and kittens need to be vaccinated frequently (every 3-4 weeks) until they are about 4 months old.
The level of maternal antibodies varies substantially within and between litters, which is why WSAVA recommends continuing the series until at least 16 weeks of age. In especially high-risk situations, vaccination may continue until 20 weeks.
Puppy Vaccination Schedule
6-8 Weeks — First Visit
Core vaccines (recommended for all puppies):
- DHPP (DA2PP) — Modified live virus vaccine protecting against Distemper, Adenovirus-2 (Hepatitis), Parvovirus-2, and Parainfluenza
What to expect:
- Complete physical examination
- Discussion of lifestyle and risk factors to determine non-core vaccine needs
- Deworming if needed
- Next appointment scheduled for 3-4 weeks later
Non-core vaccines (based on risk assessment):
- Bordetella — Recommended if boarding, attending training classes, or frequent socialization
- Leptospirosis — Consider if exposure to wildlife, standing water, or endemic areas
10-12 Weeks — Second Visit
Core vaccines:
- DHPP — Second dose to ensure adequate immunity as maternal antibodies decline
Lifestyle-based vaccines:
- Leptospirosis — First dose (if recommended based on risk)
- Lyme disease — First dose for dogs in endemic areas with outdoor exposure
- Canine influenza — First dose for dogs that will board, visit dog parks, or live in outbreak areas
14-16 Weeks — Third Visit
Core vaccines:
- DHPP — Third dose (final in initial series)
- Rabies — Required by law in most jurisdictions; timing varies by local regulations
Lifestyle-based vaccines:
- Leptospirosis — Second dose (if series was started)
- Lyme disease — Second dose (if started)
- Canine influenza — Second dose (if started)
Critical timing: The final vaccine in the series must be administered at or after 16 weeks of age to ensure maternal antibodies don't interfere with the immune response.
12-16 Months — One Year Boosters
- DHPP — Booster dose
- Rabies — Booster per local law requirements
- Lifestyle vaccines — Boosters as needed based on continued risk
Adult Dogs — Every 1-3 Years
Based on vaccine type, local regulations, and individual risk assessment:
- Core vaccines (DHPP): Every 3 years after the initial series and one-year booster
- Rabies: Per local law (1 or 3 years depending on vaccine and jurisdiction)
- Lifestyle vaccines: Annually if risk factors continue
Kitten Vaccination Schedule
6-8 Weeks — First Visit
Core vaccines (recommended for all kittens):
- FVRCP — Feline Viral Rhinotracheitis (Herpesvirus-1), Calicivirus, and Panleukopenia
What to expect:
- Complete physical examination
- Deworming
- FeLV/FIV testing if status is unknown
- Discussion of lifestyle (indoor vs. outdoor) to assess vaccine needs
- Next appointment in 3-4 weeks
Non-core vaccines (based on risk):
- FeLV (Feline Leukemia Virus) — Initially recommended for all kittens, as lifestyle may change
10-12 Weeks — Second Visit
Core vaccines:
- FVRCP — Second dose
Lifestyle-based vaccines:
- FeLV — Second dose (WSAVA and AAFP highly recommend for all kittens initially)
14-16 Weeks — Third Visit
Core vaccines:
- FVRCP — Third dose (final in initial series)
- Rabies — Required by law in most areas
Lifestyle-based vaccines:
- FeLV — Third dose if high risk (outdoor access or living with cats of unknown FeLV status)
12-16 Months — One Year Boosters
- FVRCP — Booster dose
- Rabies — Booster per local regulations
- FeLV — Booster if continued risk exposure
Adult Cats — Every 1-3 Years
- Core vaccines (FVRCP): Every 3 years after initial series and one-year booster
- Rabies: Per local law (1 or 3 years)
- FeLV: Annually if outdoor access or multi-cat household with unknown status cats
Red Flags — When to Call Your Vet
Contact your veterinarian immediately if your puppy or kitten shows any of these signs after vaccination:
- Vomiting or diarrhea that persists
- Facial swelling, hives, or widespread itching
- Difficulty breathing or collapse
- Severe lethargy lasting more than 48 hours
- Pain or swelling at injection site that worsens
- Any symptoms that concern you
Note: Mild sleepiness, decreased appetite, or slight fever for 24-48 hours after vaccination is normal and expected.
Common Questions About Pet Vaccinations
Q: What happens if I miss a scheduled vaccination?
A: Contact your veterinarian as soon as possible. Depending on how much time has passed, your vet may recommend restarting the series or simply giving the missed dose. Don't delay — your pet is vulnerable to preventable diseases.
Q: Are vaccines safe for my puppy or kitten?
A: Yes. Modern vaccines are rigorously tested and extremely safe. The benefits of preventing deadly diseases like parvovirus, distemper, and rabies far outweigh the minimal risks. Severe reactions are rare but require immediate veterinary attention.
Q: Can I use titer testing instead of vaccination?
A: Titer testing (measuring antibody levels) is an option for some core vaccines in adult animals. However, vaccination remains the gold standard for ensuring protection. Discuss with your veterinarian whether titer testing is appropriate for your pet's situation.
Q: Why can't I just vaccinate my pet once?
A: Maternal antibodies interfere with vaccines given too early. The series ensures that as maternal immunity wanes, your pet develops their own protection. The final dose at 16+ weeks is critical to ensure the vaccine "takes."

Cost and Access Considerations
Vaccination costs vary by location, clinic type, and vaccine combinations:
Typical costs per visit (USD):
- Puppy series (3 visits): $75-150 per visit
- Kitten series (3 visits): $70-140 per visit
- Rabies vaccine: $15-25 (often required separately by law)
- Exam fees: $35-65 per visit (some clinics include with vaccines)
Low-cost options:
- Humane societies: Often offer vaccine clinics at reduced rates
- Mobile vaccine clinics: Lower overhead means lower prices
- Veterinary teaching hospitals: Supervised students provide care at reduced cost
- Wellness plans: Many clinics offer monthly plans covering preventive care
Important: Ensure vaccines are properly stored, administered by trained professionals, and documented in official records. The cheapest option isn't always best when it comes to your pet's health.
Legal and Practical Requirements
Rabies vaccination: Required by law in most jurisdictions. Non-compliance can result in fines, quarantine, or euthanasia if your pet bites someone.
Boarding and grooming: Most facilities require proof of current vaccinations (DHPP, rabies, bordetella for dogs; FVRCP, rabies for cats).
Travel: Interstate and international travel require health certificates and proof of specific vaccinations. Start planning months in advance for international moves.
Dog parks and training: Many facilities require proof of vaccination before allowing participation.
