It was confirmed today (4th) that 140 people were vaccinated with the COVID-19 vaccine, which had passed the recommended period of vaccination after thawing at Korea University Guro Hospital in Seoul.



Some inoculations who have experienced adverse reactions have been visiting the emergency room since early this morning and being tested.



The Korea Centers for Disease Control and Prevention believes that the vaccine will not be effective and is considering whether to 're-vaccinate'.



According to the health authorities, during the Pfizer vaccination process at Korea Daegu Guro Hospital from the 26th to the 27th of last month, the vaccine was administered near or exceeding the recommended inoculation period after thawing.



Pfizer vaccines should be stored frozen and thawed in the refrigerator or room temperature before use.



Unopened vials (bottles) should be stored at room temperature for up to 2 hours, and should be used within 6 hours if opened and diluted in saline.



About 140 people were vaccinated against the vaccine that should be discarded, and most of them were primary recipients.



In a text message sent to inoculations late the night before, Korea University Guro Hospital said, "After thawing, it was confirmed that the recommended period for vaccination was imminent or received a vaccine that slightly exceeded." The expert deliberation committee will decide whether to re-vaccinate.”



The Guro-gu Public Health Center said, "The vaccine, which had an expiration date of August 20 or 26, was vaccinated on August 26 and 27. “, he explained.



In this accident, the vaccine was not used after the expiration date, but the vaccine was stored and used after thawing, so thorough follow-up management is required.



Person A, who was vaccinated, said, "After the vaccination, I received medical treatment due to heart palpitations and muscle pain, but I was notified by text message in the middle of the night that there had been an accident. "He pointed out.



An official from Korea University Guro Hospital said, "We are waiting for the government's judgment on whether to re-vaccinate.
