The science behind the effectiveness of pet vaccinations

The importance of pet vaccinations cannot be overstated. Vaccines are a crucial part of keeping your pet healthy and safe, as they provide immunity to many common diseases and illnesses. In this blog post, we’ll take a closer look at the science behind the effectiveness of pet vaccinations and why it’s important to keep your pet up-to-date on their shots.

What are vaccinations and how do they work?

Vaccinations, also known as immunisations, are a preventative medical treatment used to protect people and animals against diseases and illnesses. Vaccines contain a form of the virus or bacteria that causes the disease which stimulates the body’s immune system to create antibodies. These antibodies help the body to recognise and fight off any future infections from the virus or bacteria. The antibodies produced by vaccinations can last for years, which is why some vaccinations only need to be given once in a lifetime, while others need to be administered regularly.
