A specialist government hospital in Singapore has apologised to the family of one of its employees for mistakenly giving five doses of the Pfizer-BioNTech Covid-19 vaccine, three more doses than required.
The incident, which took place at the Singapore National Eye Centre (SNEC) on Jan 14, was discovered within minutes.
“Our investigations showed that it was human error resulting from a lapse in communication among the vaccination team, who had been preparing and administering the injections at that time,” The Straits Times quoted SNEC as saying.
It said the employee was admitted to the Singapore General Hospital and discharged two days later.
According to SNEC, the worker in charge of diluting the vaccine had attended to other matters, and a colleague thought the undiluted dose was ready to be administered.
The Straits Times said Singapore had vaccinated 175,000 people with the first dose of the Pfizer vaccine as of Tuesday.
Some 6,000 people have also received their second dose.
