Immunisation
Information about immunisation and why it is important for people with childhood heart disease to get vaccinated.
What is immunisation?
Immunisation is the process of receiving a vaccine and becoming immune to a disease as a result.
A vaccine is a type of medicine that trains your body’s natural defences (immune system) to fight against a particular disease. Vaccines are given to you by health care professionals.
Immunisation protects you from harmful diseases before you come into contact with them.
In Australia, free vaccines are available for a range of diseases. This includes things like tetanus and whooping cough.
Getting immunised is a safe and simple thing you can do to help keep yourself well and healthy.

Why is getting immunised important?
Keeping up to date with vaccinations is important for everyone. It protects you from disease. It also protects other people in the community by making it harder for diseases to spread.
When you have a heart condition, you may be more vulnerable to getting sick from an illness or infection. It is important to do the simple things that will help
you stay as healthy as you can. Getting immunised is a safe way to protect yourself against serious diseases.
