Immunisation is a simple and effective way of protecting children and adults against certain diseases.

  • Immunisation uses the body’s natural defence mechanism – the immune response – to build resistance to infectious diseases.
  • Young children, particularly babies, do not have the well-developed immune system that older children and adults have.  
  • It not only protects individuals who have the immunisation, but also others in our community, by increasing the level of immunity and minimising the spread of disease.

Most vaccinations need to be given several times to build long lasting protection – this is why it is important for children to complete the full recommended schedule of vaccinations at the recommended times.

  • See Vaccines (SA Health website) for more information.
  • Sometimes it is possible to ‘catch up’ if the vaccinations are not given on time.  Have a look at the 'Immunisation Calculator' if you need to 'catch up' some of your child's immunisations.

Not getting the full course of vaccinations can leave a child unprotected and still at risk of getting the disease.

Although many diseases are not as common as they were in the past, particularly in countries like Australia, it is still vitally important for children and adults to be vaccinated to help ensure we do not experience serious disease outbreaks.

Childhood Schedule – South Australia – January 2016

To find out what immunisations are needed for babies, children, adolescents and aduls in South Australia have a look at the National Immunisation Program Schedule for South Australia. November 2016.

Where can I have my child immunised?

Immunisations can be provided by your doctor, immunisation clinics, local councils, community child health nurses and by some hospitals.

Immunisation calculator

The Immunisation Calculator uses the Australian Standard Vaccination Schedule. It recommends doses of vaccine to be given at specific ages. If doses of vaccine are delayed or missed, the calculator will assist in providing a 'catch-up' schedule for future vaccine doses.


Vaccine side effects

 Vaccines, like any medication can have side effects.

  • Most vaccines can cause mild reactions.
  • If the reaction seems severe or persists and you are concerned, contact your doctor or immunisation provider.
  • If your child becomes obviously unwell it is probable that your child has a different health problem (eg. a cold or other viral infection), and it may be wise to have the child checked by a doctor.

Reactions do not usually last for more than 48 hours, and the following may help to relieve symptoms.

  • Place a cold cloth on the injection site if it is red or swollen (do not place ice directly onto the skin).
  • If the child has a fever or seems in pain, some paracetamol or ibuprofen may help.
  • If the child is not drinking or eating as much as usual, offer some extra drinks (breast milk, formula or water).
  • Many children need extra cuddling and comforting for a day or so.

What is the Australian Childhood Immunisation Register (ACIR)?

The Australian Childhood Immunisation Register (the Immunisation Register) is a national immunisation register that records details of vaccinations given to children and young people up to 20 years of age who live in Australia -  done as part of the Commonwealth 'No jab - no pay' immunisation policy. When your child is vaccinated, your doctor or immunisation nurse sends the vaccination information to the Immunisation Register.

If you have misplaced your child's vaccination details, you can contact the Immunisation Register and request a copy.

Immunisation and family payments

  • Your child has to be up-to-date with immunisations, or have an exemption, so that your family can receive payments such as the Child Care Benefit . 'No jab - no pay'

Immunisation before, during and after pregnancy

Some immunisations, including rubella immunisation, help protect an unborn baby if the mother has the immunisations before she becomes pregnant. Influenza and whooping cough immunisation can be done during pregnancy. For more information have a look at

and these topics on our Pregnancy Website
