Update on GSK Hepatitis B vaccine availability

03 October 2017

We are currently experiencing a supply constraint of Twinrix Junior  (combined hepatitis A and hepatitis B vaccine) due to the current high demand for hepatitis B-containing vaccines in Australia. We anticipate Twinrix Junior to be back in stock by end November 2017.

Twinrix Adult (combined hepatitis A and B vaccine) is now back in stock following a recent supply constraint.


GSK is currently experiencing an on-going supply constraint of Engerix-B Adult dose (hepatitis B surface antigen recombinant (yeast) vaccine) in Australia. Production is now back to normal however, it will take time to re-build capacity.

At this stage we are unable to confirm a re-supply date.

Engerix-B Paediatric

We are currently experiencing an intermittent supply constraint of Engerix-B paediatric dose for the private market. We expect to return to supply by the end of 2017.

Supply of GSK vaccines containing hepatitis B to government programs is not impacted.

We understand that these stock-outs may be distressing for those who are not covered by government programs and who may be required to vaccinate themselves for occupational reasons or because they are planning on travelling to hepatitis-affected areas.


Please visit the TGA website for ongoing updates to supply.
