Pregnant women and babies
In WA there are 2 options to protect your baby against RSV infection.
Maternal RSV vaccination (Abrysvo)
Option A: a maternal RSV vaccine recommended and available to all pregnant women from 28 weeks of pregnancy, during every pregnancy.
Getting one dose of Abrysvo generates RSV antibodies that cross the placenta and help protect your baby from birth for up to 6 months, when they are most at risk. You can get Abrysvo at the same time, or separately from, other maternal vaccines such as whooping cough (pertussis) and influenza.
Infant immunisation (Beyfortus, also known as nirsevimab)
Option B: an immunisation availablefor infants and eligible children under 2 years of age. Babies can receive Beyfortus at the same time as other routine vaccines, but it is best administered before they leave the birthing hospital.
If you didn’t receive Abrysvo during pregnancy, your baby should be immunised with Beyfortus before they leave hospital, as it begins protecting them from RSV almost immediately. Some newborns whose mother received Abrysvo, and certain children, may still need a Beyfortus immunisation if they are at high risk of RSV-related illness. Speak with your immunisation provider for more information about medical conditions that can increase the risk of RSV-related illness.
In WA, from 1 April 2026 until 30 September 2026, Beyfortus is available to:
- babies born between 1 April and 30 September 2026, if their mothers were not vaccinated with Abrysvo at least 2 weeks before giving birth
- babies born between 1 October 2025 and 31 March 2026, irrespective of whether their mother was vaccinated in pregnancy
- infants with specific high-risk medical conditions, irrespective of whether their mother was vaccinated in pregnancy
- Aboriginal children born on or after 1 October 2024 who are entering their second RSV season
- children aged 8 months to 2 years with specific high-risk medical conditions who are entering their second RSV season (your child’s doctor will let you know if your child should receive a dose).
This guidance applies throughout WA, except in the Kimberley and Pilbara regions, where RSV immunisation is available to newborns and young children throughout the year, due to continuous RSV circulation in these areas.
If you are unsure about eligibility, please use this helpful tool (external site) provided by The Kids Research Institute.
Note: Beyfortus is available regardless of eligibility for Medicare benefits.
Older adults
Arexvy is offered to:
- all adults aged 65 and over in residential aged care homes
- all adults aged 50- 59 years in residential aged care homes with increased risk of RSV disease
More information on eligibility for Arexvy for additional vulnerable groups will be available soon.
Note: Arexvy is not registered for use during pregnancy and should not be given to pregnant women.
Arexvy RSV vaccine can be given at the same time as other vaccines, such as COVID-19, influenza, shingles and pneumococcal vaccines. Speak to your immunisation provider for more information.
