On the 26th, when the government started free vaccination for influenza (flu) vaccines for people aged 62 to 69, older people lined up for vaccination at the Seoul West Branch of the Korean Association for Health Management.

Reports of deaths from influenza (flu) vaccines have increased significantly this year, but the burden is being put on that it is not a problem with the vaccine or the vaccination process. Autopsies of the newly added deaths continue to show that there are no abnormalities in the effectiveness and safety of the vaccine.
The number of deaths reported after influenza vaccination up to 0 am on the 29th has registered 72 cases (people), the highest in history in the last 10 years, but it has been confirmed that there have been no cases in which there have been revealed the causal relationship between the vaccine and the occurrence of death.
On the 29th, Park Young-joon, in charge of epidemiological research and analysis, said in a briefing on ‘The Current Status of Influenza Vaccines for the 2020-2021 Season from the Disease Management Administration’, “As a result of performing autopsies on 40 cases of death reports received so far, the causality between the vaccine and death is clear.” It is not supported, “he said.” The bottom line (no problem with the vaccine) it will not be reversed. “
The National Institute for Scientific Research carried out an autopsy of 40 cases until October 28 out of a total of 72 deaths reported until October 29. The remaining 31 cases were not implemented for reasons such as request for survivors or death from underlying diseases, while the other is being confirmed by an autopsy doctor.
As a result of these 40 autopsies, there were no cases of abnormal findings at the vaccination site. There were 11 cases in which the cause of death could only be confirmed by early autopsy findings, and the cause of death was aortic dissection, cerebral hemorrhage, pulmonary thromboembolism, and intestinal obstruction.
In addition, 29 cases of ischemic heart disease (myocardial infarction), valvular heart disease, heart-related diseases such as cardiac hypertrophy, and pneumonia were observed visually.
Factors other than the autopsy did not show any circumstances that could cause the vaccine to be a problem. The Agency for Disease Control and Prevention plans to release the vaccine name and manufacturing number and immediately discontinue vaccination in the event of two or more cases of serious adverse reactions that cannot exclude causation of vaccination and death. , but there is no such issue yet.
In fact, death reports were received for 4 undiluted vaccines without being biased against any of the 5 undiluted vaccines arriving in Korea. In the case of 100,000 vaccines, death reports of 0.4 to 0.5 are reported.
For non-fatal vaccines, the number of vaccinations in Korea is lower than for other vaccines. A total of 5 undiluted vaccines were imported and manufactured in Korea, and 499.9224 people received the vaccine with undiluted solution A at 0:00 a.m. on the 29th, of which 27 were found dead. The number of deaths per 100,000 inhabitants is 0.5.
Except for an undiluted solution with the lowest inoculation amount (69.6884 people inoculated), the other undiluted solutions showed similar levels of non-causal death reporting rates. Regarding the vaccine that uses undiluted solution B, 562,7710 people were vaccinated and 23 people reported death. It is about 0.4 per 100,000 people. In addition, 11 of 2,275,3369 vaccines were reported for undiluted vaccine C and 11 of 2,232,163 vaccines for undiluted vaccine D.
Furthermore, as a result of comparing and analyzing the number of vaccinations versus the number of deaths reported to assess the relationship between the vaccine distribution process, the vaccination institutions and the cases of death notification, there were no cases of vaccination in the same vaccination institution among the deceased and no other specific issues were confirmed.
The Agency for Disease Control and Prevention predicted the high number of death reports this year due to the concentration of vaccines and psychological anxiety among the elderly. Lee Seon-gyu, head of the vaccination department at the Agency for Disease Control and Prevention, said: “It is estimated that more than 70% of people aged 70 years or older have been vaccinated on the first and second day free vaccination “.
Furthermore, Choi Won-seok, professor of infectious medicine at Ansan University Hospital, said: “There was great social interest in death after vaccination. If there are many deaths due to vaccines, it will be worth seeing how the mortality rates of the unvaccinated groups compared to previous years are different. ” .
“As an analogy, crossing the street in a pedestrian crossing does not mean that there is no probability that a traffic accident will not occur, so there is no 100% safety in vaccination,” he said. “The least certain is that the benefits are obviously greater when it is vaccinated.” did.
Consequently, the Korean Centers for Disease Control and Prevention judged the causality between the recent increase in death cases and influenza vaccination to be very low as a result of the damage research group’s review based on the Epidemiological investigation and a more detailed analysis of the reported cases of death after the influenza vaccination received so far. do. We plan to continue conducting further research and analysis.
Meanwhile, this year’s influenza vaccination status is approximately 16.4 million as of 0:00 on October 29, of which the number of vaccines targeted to the national vaccination project is 11.3 million. A total of 1551 adverse reactions were reported after vaccination.
