[Asia Economy Yeongnam Reporting Headquarters Reporter Kim Yong-woo] It has been revealed that 189 cases occurred at a clinic in Busan where the amount of COVID-19 vaccine injected was less than the prescribed dose.

According to Busan City on the 12th, there were 272 cases of COVID-19 vaccine misadministration in Busan, and nearly 70% of these misadministrations occurred at one entrusted medical institution.

The vaccination staff mistakenly administered less vaccine than the recommended dose. Health authorities believe there is no significant problem with immune formation and reportedly did not impose any special sanctions on the medical institution.

During a vaccine status inspection of entrusted medical institutions in June, Busan City confirmed that a vaccine staff member at one clinic-level medical institution administered less vaccine than the recommended dose to 189 vaccine recipients.

The medical staff at this institution consists of one doctor and three nursing personnel.

The number of people injected with 0.01ml less than the required 0.5ml dose was 53, those injected with 0.04ml less were 56, and those injected with 0.1ml less were 80.

There were no reports of adverse reactions due to the misadministration.

According to National Assembly Health and Welfare Committee member Baek Jong-heon, among the 272 vaccine misadministration cases in Busan, 194 were dosage errors, the most frequent, followed by 63 cases of vaccine type and storage errors, and 10 cases of timing errors.

Busan’s misadministration cases ranked third after Gyeonggi Province (594 cases) and Seoul (332 cases).

Busan City considers vaccine underdosing not serious enough to terminate the vaccine administration contract and has instructed the medical institution to strengthen education to prevent recurrence of vaccine misadministration.

A Busan City official explained, “The vaccination staff confused the dosage and administered a slightly smaller amount than the recommended dose,” adding, “While vaccine underdosing may affect immune formation more than cause side effects, it is judged that the amount administered was not insufficient to generate immunity.”
