Pet Vaccination Schedule|Complete Guide to Kitten and Puppy Vaccines

Pet vaccines are an essential line of defence protecting your pet from deadly infectious diseases. Whether it's cat vaccines or dog vaccines, timely vaccination can effectively prevent serious diseases such as feline panleukopenia, canine distemper, and rabies. This article provides a detailed explanation of the kitten vaccination schedule, puppy vaccination timing, vaccine types, and important considerations to help you establish complete immune protection for your pet.

Why Do Pets Need Vaccinations?

Pet vaccines stimulate the immune system to produce antibodies, enabling pets to effectively fight off pathogens when exposed, preventing infection or reducing disease severity.

Importance of Vaccination

  • Prevents Fatal Diseases: Many infectious diseases like feline panleukopenia and canine distemper have extremely high mortality rates
  • Protects Young Animals: Kittens and puppies have immature immune systems and need the most protection
  • Stops Disease Spread: Herd immunity reduces pathogen transmission in the community
  • Legal Requirement: Hong Kong law requires dogs to be vaccinated against rabies
  • Boarding/Grooming Requirements: Many facilities require proof of vaccination

Core vs Non-Core Vaccines

TypeDefinitionExamples
Core Vaccines Must be given to all pets; prevents the most common and serious diseases Cats: FVRCP; Dogs: DHPPi, Rabies
Non-Core Vaccines Depends on living environment and risk factors Cats: Feline Leukaemia; Dogs: Leptospirosis, Kennel Cough

Types of Cat Vaccines

Cat vaccines mainly consist of 3-in-1 and 4-in-1 combinations, which are essential vaccines for all cats:

3-in-1 Vaccine (FVRCP / F3)

The core vaccine all cats must receive—one injection prevents three fatal diseases:

  • Feline Viral Rhinotracheitis (FVR/FHV-1): Feline herpesvirus, causes "cat flu"
  • Feline Calicivirus (FCV): Causes oral ulcers, respiratory infections
  • Feline Panleukopenia (FPV/Feline Distemper): Gastrointestinal disease with extremely high mortality rate

4-in-1 Vaccine

3-in-1 + Feline Leukaemia Virus (FeLV):

  • Suitable for cats that go outdoors or have contact with other cats
  • Recommended for multi-cat households
  • Feline leukaemia spreads through body fluids and can cause immune system collapse

Other Cat Vaccines

  • Rabies Vaccine: Not legally required in Hong Kong, but needed for travel or export
  • Feline Infectious Peritonitis (FIP) Vaccine: Limited effectiveness, rarely used

Kitten Vaccination Schedule

Below is the recommended kitten vaccination schedule to ensure your pet receives complete protection:

AgeVaccineNotes
6–8 weeks 3-in-1 (FVRCP) First dose Kitten's first vaccination
10–12 weeks 3-in-1 Second dose 3–4 weeks after first dose
14–16 weeks 3-in-1 Third dose Completes primary immunisation
1 year 3-in-1 Booster First annual booster
Annually/Every 3 years 3-in-1 Booster Depends on vaccine brand and veterinary advice

Why Are Three Doses Needed?

Maternal antibodies obtained from mother's milk can interfere with vaccine effectiveness. Since the timing of maternal antibody decline varies between kittens (approximately 6–16 weeks), multiple vaccinations ensure that after antibodies decline, the vaccine can effectively stimulate the immune system.

Types of Dog Vaccines

Dog vaccines come in more varieties, mainly divided into core and non-core vaccines:

Core Vaccines

DHPPi 5-in-1 Vaccine

The core vaccine all dogs must receive:

  • D - Distemper: Affects respiratory, gastrointestinal, and nervous systems
  • H - Infectious Canine Hepatitis (Hepatitis/CAV-1): Caused by adenovirus
  • P - Canine Parvovirus: Gastroenteritis with extremely high mortality rate
  • Pi - Parainfluenza: Respiratory infection

Rabies Vaccine

Mandatory under Hong Kong law:

  • Dogs must be vaccinated before reaching 5 months of age
  • Must apply for dog licence from AFCD (Agriculture, Fisheries and Conservation Department)
  • Booster required every 3 years
  • Rabies can be transmitted to humans with a nearly 100% mortality rate

Non-Core Vaccines

  • Leptospirosis Vaccine: Spreads through contaminated water; can be transmitted to humans
  • Kennel Cough Vaccine: Recommended for dogs with frequent contact with other dogs
  • Lyme Disease Vaccine: Spread by ticks; consider for dogs that go hiking

Puppy Vaccination Schedule

Below is the recommended puppy vaccination schedule:

AgeVaccineNotes
6–8 weeks DHPPi 5-in-1 First dose Puppy's first vaccination
10–12 weeks DHPPi 5-in-1 Second dose Can deworm simultaneously
14–16 weeks DHPPi Third dose + Rabies first dose Completes primary immunisation
5 months Apply for dog licence Required by Hong Kong law
1 year DHPPi Booster First annual booster
Annually DHPPi Booster Maintains immunity
Every 3 years Rabies Booster Required by Hong Kong law

Vaccination Considerations

Before Vaccination

  • Ensure Good Health: Do not vaccinate if showing symptoms like diarrhoea, vomiting, coughing, or fever
  • Inform Vet of Medical History: Allergies, current medications
  • Avoid Recent Environment Changes: Newly adopted pets should first adapt to their new environment
  • Deworming: Recommended to complete deworming before vaccination

After Vaccination

  • Observe for 30 Minutes: Stay at the clinic to watch for immediate allergic reactions
  • Monitor for 48 Hours: Watch for delayed side effects
  • Avoid Vigorous Exercise: Let the body focus on producing antibodies
  • Avoid Bathing: No baths for one week after vaccination
  • Limit Outings: Avoid taking kittens and puppies outside until primary immunisation is complete

Common Side Effects

Most side effects are mild and temporary:

  • Mild swelling or soreness at injection site
  • Mild fever
  • Slightly reduced appetite
  • Slight lethargy
  • These usually resolve within 1–2 days

Situations Requiring Emergency Veterinary Care

  • Facial swelling (allergic reaction)
  • Difficulty breathing
  • Persistent vomiting or diarrhoea
  • Collapse, unable to stand
  • Severe swelling or abscess at injection site

Pet Vaccination FAQs

Q1: Does my indoor cat still need vaccinations?

Yes! Viruses can be brought into the home on owners' clothes and shoe soles. Cats may also be born carrying viruses that haven't yet caused illness. Cat vaccines can reduce the chance of disease onset and severity.

Q2: What if I missed the vaccination date?

If delayed by only a few days to a week, you can usually continue with the original schedule. If significantly delayed, you may need to restart primary immunisation. Consult with your veterinarian for the most appropriate plan.

Q3: What about adopted adult cats/dogs with no vaccination records?

You can restart following the adult animal vaccination schedule: second dose 4 weeks after the first dose, then annual boosters. Adult cats and dogs usually only need two doses to complete primary immunisation.

Q4: Do vaccines provide 100% protection?

No vaccine provides 100% protection, but they significantly reduce infection risk and disease severity. Even if infection occurs after vaccination, symptoms are usually milder.

Q5: Do senior pets still need vaccinations?

Yes, though frequency can be adjusted. Senior pets have declining immunity and still need vaccine protection. Some veterinarians recommend antibody testing to determine whether boosters are needed based on results.
