ANN/THE STRAITS TIMES – There have been 130 people in Singapore who received a wrong dose of COVID-19 vaccine since Singapore began its vaccination exercise in late 2020, with 11 people affected by overdosing and 119 having received a lower dose than the recommended amount of a vaccine.
This is out of about 16 million doses of COVID-19 vaccines administered in Singapore as at September 26, Senior Minister of State for Health Janil Puthucheary said in Parliament yesterday.
Of these incidents, seven were children between the ages of five and 11, none of whom had any adverse reactions, he added.
“The adults had either no adverse reactions or recovered uneventfully,” he said.
His comments followed an incident on September 15 when two adults were each given a full vial of undiluted Pfizer-BioNTech COVID-19 vaccine at a ProHealth Medical Group clinic in Hougang. A full vial of undiluted vaccine contains five doses.
One patient was hospitalised after experiencing a headache and an increased heart rate, but was later discharged, while the other did not report any adverse reactions.
Dr Puthucheary said the Ministry of Health’s (MOH) investigation of the incident is ongoing, and that MOH will take appropriate enforcement actions if any regulatory breaches are found.
He was replying to questions from Joan Pereira, Dr Wan Rizal and Gerald Giam such as on the requirements for clinics to report when such cases happen, and safeguards to prevent similar incidents from occurring in the future.
Dr Puthucheary said vaccination providers are required to report to MOH no later than three hours after vaccine administration errors and medical emergencies following vaccination.
Providers are also required to inform patients immediately when a vaccination error has occurred and to monitor such patients’ health with daily calls for the next seven days to ensure their well-being.
In a supplementary question, Giam noted that there was a four-day delay between when the incident at the ProHealth clinic occurred and when MOH was informed on September 19.
