Vaccine reactions explained
Vaccination is a very effective way of preventing disease. When we vaccinate, we give a tiny amount of a germ (in a safe form) so that the body can create defensive antibodies, which will fight the germ if it enters the body in the future. Millions of pets are vaccinated each year and most don’t suffer any side effects at all.
Vaccine reactions happen when your pet reacts to the germs in the vaccine or the substance that they are sitting in.
If your vet thinks that your pet is at a higher risk of having a vaccine reaction (for example if they are old and frail, unwell, underweight or suffering from an illness), they will discuss the risks with you so that you can make an informed decision about whether to vaccinate or not.
