What is immunisation?

Immunisation is a safe and effective way of protecting your child against serious diseases. 

Immunisation protects your child from harmful infections before they come into contact with them. It uses their body’s natural defences to build resistance to specific infections. When they come in contact with that disease in the future, their immune system remembers it, and responds quickly to prevent the disease from developing. 

After immunisation, your child is far less likely to catch the disease. If your child does catch the disease, their illness will be less severe and their recovery quicker than an unimmunised child. 

Immunisation or vaccination – what’s the difference?

‘Vaccination’ means getting a vaccine – either as an injection or an oral dose.

‘Immunisation’ is the term for both the process of getting the vaccine and becoming immune to the disease as a result.
