Respiratory Syncytial Virus (RSV) immunisation
- The RSV imunisation is safe and effective at preventing RSV.
- One dose of nirsevimab protects babies for at least 5 months
- Once your child receives the nirsevimab immunisation, it will be recorded on the Australian Immunisation Register (AIR)
From April 2024, the RSV immunisation, nirsevimab (Beyfortus®) will be available to eligible babies and children born from 1 October 2023 to 30 September 2024.
Why should you immunise your baby?
The antibody in nirsevimab can prevent severe lung disease caused by RSV. Medical studies show nirsevimab to be about 80 per cent effective at preventing RSV-associated hospitalisation among infants entering their first RSV season (typically from May to September in WA) and 90 per cent effective at preventing an admission to an intensive care unit (ICU).
When is the best time to immunise your baby against RSV?
One dose of nirsevimab protects babies for at least 5 months, which is the length of an average RSV season (typically from May to September in WA).
Babies born during the RSV season should receive a single dose of nirsevimab before leaving the birthing hospital.
Is the RSV immunisation safe and effective?
The RSV imunisation is safe and effective at preventing RSV.
Studies have shown that the immunisation used in WA immunisation programs are safe to use on babies and children.

- as a catch-up program for babies born from 1 October 2023 to 30 April 2024
- to all Aboriginal children born from 1 October 2022 to 30 September 2024
- to some medically at-risk children in their second RSV season born from 1 October 2022 to 30 September 2023 (your child’s doctor will advise you if your child should receive a dose).

What should I let my child’s health care provider know before the injection?
Tell your health care provider if your child:
- has ever had a serious allergic reaction to a previous dose of medicine containing antibodies
- has a bleeding disorder
- is currently experiencing a moderate or severe illness.
Children experiencing a minor illness, such as a cold, can safely receive the RSV immunisation. Children who are moderately or severely ill should usually wait until they recover. Your health care provider can give you more information about what is best for your child.
Possible side effects
Like all medicines, the nirsevimab may cause side effects in some babies.
Although uncommon, side effects can include:
- rash
- pain, redness and swelling at injection site
- fever
Almost all reactions are minor and usually go away within a few days. Serious side effects from immunisation are very rare. Learn more about possible side effects, how to manage them, and what to do when you have concerns about side effects.
