Queensland health authorities have confirmed that an aged care worker received the wrong second dose of the COVID-19 vaccine.
The woman was given a Pfizer dosage for her first jab but received AstraZeneca for the second this week, not realising the error until she was given a pamphlet after the injection.
The employee of the Ipswich aged care facility, west of Brisbane, was monitored for an hour by healthcare professionals at the clinic before being sent home with an ice pack for a headache, 9 News reported.
She was told to watch for any adverse reactions and to call an ambulance if she became unwell.
On Friday afternoon, Queensland chief health officer Jeannette Young confirmed the woman had received the wrong dosage.
“I’m sure the place where it happened will look at how that occurred, but she’s fine today, which is very good news,” she told reporters.
The mix-up comes after the Prime Minister on Thursday night revealed new medical advice for the AstraZeneca jab, recommending Australians under 50 not receive the vaccine due to the rare possibility of blood clots.
Scott Morrison said the guidance was based on advice from the Australian Technical Advisory Group on Immunisation (ATAGI).
The AstraZeneca vaccine will continue to be issued to those when the benefits outweigh the risks of the deadly virus.
Those include elderly Australians, who are more likely to become seriously ill from coronavirus than young people.
Administration of the Pfizer vaccine will not be affected.
ATAGI considered evidence from colleagues in Europe, where there were a small but concerning number of cases where people developed blood clots after receiving the AstraZeneca vaccine.
