Six people are suspected to have received an ultra-low COVID-19 vaccine dose due to an error at the Flagstone Community College pop-up clinic two Saturdays ago.
Queensland Health says it isn’t possible to trace which six out of the 175 people were given the ultra-low dose. So they will all need to be revaccinated to guarantee immunity.
A review has indicated one vial was used twice, meaning the doses drawn on the second use were over-diluted with saline.
It’s not yet clear what caused the error.
