Multiple Queenslanders given ‘ultra-low dose’ in vaccine bungle

A review is being carried out by Queensland Health after it was revealed that six people have been given an ultra-low dose of the vaccine.

Authorities had to call 175 people yesterday letting them know that they may have been impacted by the vaccine bungle, which happened at the Flagstone Community College pop up clinic on October 23.

While only six people were administered an ultra-low dose due to a preparation error, it’s not clear which six people out of the 175 people it was.

The initial review has found that one vial of the vaccine was used twice, meaning the doses drawn on the second use were over-diluted, according to Queensland Health.

Chief Health Officer Dr Peter Aitken says it won’t be harmful to the people affected, but it could affect their immunity.

“Unfortunately there is no ability to trace which six of the 175 people through the vaccination pop-up clinic were given the ultra-low dose, and we will contact all those impacted to discuss revaccination if required.

“A review is underway to further understand what happened, what caused the error and how processes can be improved,” Dr Aitken said.

“We have sought expert medical advice from the Commonwealth Department of Health on this matter, and will work with those impacted to ensure optimal immune response to the vaccination is achieved,” Dr Aitken said.

“Of those 175, 148 were receiving their first dose and 27 were receiving their second dose.

“We will offer a dedicated pop-up clinic locally for people who are recommended to receive a repeat dose to ensure they are fully vaccinated against COVID-19,” he said.

Metro South Health COVID-19 Incident Controller Dr Michael Cleary apologised for the error.

“I apologise for any distress this has caused to those 175 people and their families. We will, of course, be supporting every single person impacted,” Dr Cleary said.

“I am incredibly grateful that the error was picked up quickly following the conclusion of the clinic as a result of our safeguards and due diligence.

“A full incident report is being prepared which will allow me and my staff to better understand what needs to be done to improve processes at future pop-up clinics.”
