Entry 2020.09.29 19:38 | Revision 2020.09.29 20:33

The number of people estimated to have received the influenza (flu) vaccine, which was discontinued due to the “room temperature exposure” accident, increased significantly to 873.

On the 29th, the Korea Centers for Disease Control and Prevention (KCDC) stated in the explanatory data on the temporary suspension of the national influenza vaccination project: “The number of vaccines purchased by the government was reported in a total of 14 regions as of yesterday (28) This is an increase of 466 people in one day since the announcement (407 people) on the 27th.

By region, Jeonbuk was the largest with 279 cases. Next, Gyeongbuk 126 cases, Incheon 86 cases, Busan 83 cases, Chungnam 74 cases, Seoul 70 cases, Sejong 51 cases, Gyeonggi 49 cases, Jeonnam 31 cases, Gyeongnam 10 cases, Jeju 8 cases, Daejeon 3 cases, Daegu 2 cases , Chungbuk There was a case.

By vaccination period, starting on the 22nd, when the government policy to stop vaccination was urgently notified, 605 people were vaccinated before, 178 people on the 22nd, and 90 people after. Except on day 22, 695 cases before and after vaccination violated vaccination guidelines.

In response, the Agency for Disease Control and Prevention said: “The vaccination cases before the start of the project (before 21 days) and after the suspension notification date (after 23) did not comply with the National influenza vaccination project guidelines. It appears this is a case where business disruption was not recognized. ” After the investigation, it is known that the Agency for Disease Control and Prevention will take measures such as canceling the consignment contract of the national vaccination project to medical institutions that violated the vaccination guidelines.

The vaccine distributed by Shinsung Pharm, which suffered exposure at room temperature, is a vaccine for people aged 13 to 18 and over 62, and 5.78 million people have already been supplied nationwide. Shinsung Pharmaceutical is known not to adhere to the principle of “refrigerated distribution” (cold chain), such as opening the refrigerator car door or leaving the product on the ground during the vaccine delivery process. After confirming it, the government temporarily suspended the national vaccination project on the 21st.

The safety of the room temperature exposure vaccine has not yet been confirmed. However, it is noted that if the protein of the vaccine is modified due to temperature changes, the efficacy of the vaccine may change or become an ‘aqueous vaccine’ that has no efficacy, so it is indicated that it must be subjected to close verification. The sterility test, which takes about two weeks, is currently underway, and the final result is scheduled to be released from 6 to 7 next month, right after the Chuseok holiday.
