Q-VAX® Vaccine Supply Update
10 November 2026
SSS Australia has been advised by CSL Seqirus that Q-VAX® (inactivated Coxiella burnetii) Vaccine is currently out of stock and has been listed as unavailable on the Therapeutic Goods Administration (TGA) Medicines Shortage Database.
According to CSL Seqirus, Q-VAX® is a biological product manufactured from purified, inactivated Coxiella burnetii bacteria. Due to the complexity of the manufacturing process, biological variations between batches can result in delays to product release.
At this stage, CSL Seqirus anticipates that new stock will be released in late December 2026 and become available to customers in early January 2027. However, these timelines remain subject to manufacturing and release processes.
Backorders and Supply Requests
During the out-of-stock period, SSS Australia will not be able to accept backorders, maintain waitlists, or hold future supply requests for Q-VAX® Vaccine. This aligns with guidance provided by CSL Seqirus, who have advised that they will not be accepting or reviewing Q-VAX® supply requests, nor maintaining a wait list while stock remains unavailable.
Any requests received during this period cannot be reserved against future stock availability.
Important Information for Healthcare Providers
Although Q-VAX® Skin Test remains available, CSL Seqirus advises that healthcare providers should not administer Q-VAX® Skin Tests or run Q fever pre-screening clinics until vaccine supply has been reinstated and vaccine stock is available at the clinic.
This recommendation is due to the requirement for skin test results to be read seven days after administration before eligible patients can proceed to vaccination.
Staying Informed
SSS Australia understands the impact this shortage may have on healthcare providers and their patients. We are monitoring the situation closely and remain in regular contact with CSL Seqirus.
We will provide further updates as soon as additional information becomes available regarding supply timelines and stock availability.
