Vaccinations in pets are one of the most important preventative tools we have in veterinary medicine. They protect dogs and cats from serious, often fatal diseases that are still present in our environment. While some owners question whether vaccinations in pets are necessary every year, the reality is that appropriate vaccination schedules save lives and prevent widespread outbreaks.
Understanding why vaccinations in pets are given — and how often they should be administered — can help you as a pet owner to make informed, responsible decisions about your pet’s health.
Why Do We Vaccinate Pets?
Vaccinations work by stimulating the immune system to recognise and fight specific infectious diseases. When your pet is exposed to a virus or bacteria in real life, their immune system can respond quickly and effectively.
Core vaccines protect against severe diseases such as:
For dogs:
- Parvovirus
- Distemper
- Adenovirus (hepatitis)
- Rabies
For cats:
- Feline panleukopenia
- Feline herpesvirus
- Feline calicivirus
- Feline leukaemia virus (FeLV)
- Rabies
These diseases can cause severe illness, long-term complications or death. Many are highly contagious and can spread rapidly in communities.

How Often Should Vaccinations Be Given?
Vaccination schedules depend on:
- Your pet’s age
- Their lifestyle
- Local disease risk
- Previous vaccination history
Puppies and kittens require a series of vaccinations starting at around 6–8 weeks of age, repeated every 3–4 weeks until approximately 16 weeks. This ensures adequate immune protection as maternal antibodies decline.
Adult pets typically receive:
- Annual health checks
- Booster vaccinations as recommended
- Rabies vaccinations according to legal requirements
Not all vaccines need to be given every year, but annual veterinary visits are essential to assess what is appropriate for your pet.
Are Vaccinations Safe?
Vaccinations in pets are very safe. Mild side effects such as temporary lethargy or slight swelling at the injection site can occur, but serious reactions are rare.
The risks of not vaccinating are far greater than the minimal risks associated with vaccination. Diseases like parvovirus and panleukopenia are still seen in South Africa and can be devastating.
What About Indoor Pets?
Even indoor pets require vaccinations. Viruses can be carried inside on shoes, clothing or other animals. Cats that never leave the house can still contract serious viral infections.
Vaccinations in pets are part of responsible ownership — not just for your own animal, but for the wider pet community.
Vaccination Visits Are More Than Just Injections
A vaccination appointment is also a full health check. During this visit we:
- Examine teeth and gums
- Check weight and body condition
- Listen to the heart and lungs
- Assess joints and mobility
- Discuss diet and parasite control
This allows us to detect early signs of disease before they become serious.
