important for your pet?

Why vaccinate?

Vaccinations protect pets from potentially deadly diseases.

The injections contain a weak or man-made version of a disease. This triggers your pet’s body to produce antibodies to fight the disease. If they catch the same disease in the future, their body will recognise it and fight it off much more effectively.

Use of vaccinations – or ‘jabs’ – has helped to stop pets getting sick and has saved millions of lives over the last few decades. There are lots of illnesses that used to be common but now are rarely seen by vets, thanks to vaccinations stopping them spreading. If owners stop vaccinating their pets, we’ll see a lot of these rare conditions coming back and more seriously ill pets will be in need of lifesaving treatment.


It’s important that young pets are vaccinated early to protect them. This is called their ‘primary vaccination course’. Your pet will need two rounds of injections before they’re fully protected and are able to safely mix with other animals.

Young pets are at a much higher risk of catching serious illnesses. When young pets do get ill, these diseases are more likely to be fatal and, even for the lucky pets who fight off the disease, can cause lifelong health issues.


Your pet will need regular booster injections throughout their life to maintain their level of protection. Some boosters are needed every year and others every 3 years. Speak to your vet about when your pet needs their next booster.

If your adult pet hasn’t had regular booster shots or you’re not sure about their vaccination records, they may need to start their primary vaccination course again. Speak to your vet for more advice.
