Q fever vaccine shortage: new stock timing remains provisional

Australia faces a temporary interruption to Q-VAX vaccine supply after manufacturing problems, ABC News reported on 12 November. CSL Seqirus told the broadcaster that it had expedited two batches and expected their release in late December.
A 10 November update from medical distributor SSS Australia says new stock is anticipated to reach customers in early January 2027 after a late-December release. Both dates remain subject to manufacturing and release processes, rather than a guaranteed delivery date.
Q fever is a bacterial infection associated with animals including cattle and sheep. The distributor said vaccine supply was unavailable and it could not accept backorders during the interruption. People seeking vaccination should check current availability with their healthcare provider rather than assume a clinic has stock.
