General practices across Victoria are reporting fuller appointment books for Beyfortus nirsevimab as the state-funded seasonal program enters its final weeks, with some clinics quoting two-week waits for infants who missed hospital birth doses.
The National RSV Mother and Infant Protection Program combines National Immunisation Program funding for the Abrysvo vaccine in pregnancy with state and territory programs that supply monoclonal antibodies to eligible babies. Victoria funds Beyfortus from mid-March through 30 September 2026 for newborns and infants under eight months who did not receive timely maternal vaccine, as well as for higher-risk children up to 24 months.
Who qualifies
Eligibility flowcharts published by the Department of Health list medical risk conditions—including significant prematurity, congenital heart disease and severe immunosuppression—and extend second-season doses to Aboriginal and Torres Strait Islander children aged eight to 24 months. Dosing depends on weight: infants under five kilograms receive 50 milligrams intramuscularly, while heavier babies receive 100 milligrams.
GPs, hospital birthing units, Aboriginal community-controlled health organisations and some council immunisation sessions can administer doses. Parents who received Abrysvo at least two weeks before delivery generally do not need Beyfortus for the newborn unless other risk factors apply.
Seasonal pressure
Paediatricians warn that respiratory syncytial virus hospitalisations rise through winter and early spring. Northern hemisphere data show monoclonal antibodies cut severe disease in infants, but supply must reach clinics before virus circulation accelerates. Cold-chain requirements mean rural practices batch appointments to avoid wasting multi-dose vials.
Adverse events should be reported to SAEFVIC in Victoria. The state immunisation hotline fields parent questions about co-administration with routine childhood vaccines. Officials urge families not to delay six-week immunisations because of RSV appointments—schedulers can align visits when stock allows.
Other states run parallel seasons with slightly different dates; NCIRS publishes a consolidated table updated through April 2026. Families moving interstate should confirm eligibility with their new jurisdiction before assuming a Victorian dose counts for program reporting.
Supply and equity
Pharmacy wholesalers said Beyfortus vials are allocated weekly to match clinic orders, but sudden heatwaves that drive RSV circulation can empty fridges faster than replenishment trucks arrive. Rural health advocates want mobile immunisation vans to carry monoclonal doses alongside routine childhood vaccines.
Private insurers do not fund Beyfortus for families outside state criteria, pushing some parents toward paid paediatrician visits that cost more than the drug itself.
