When quarantine authorities recently surveyed 1,440 cases of serum collected from 13 cities and provinces across the country, including Daegu, only one case was confirmed to have a ‘neutralizing antibody’ that neutralizes Corona 19. The antibody retention rate is only 0.07%. It is evaluated that it has been reconfirmed that the herd immunity that is possible when 60% of people have antibodies is not a quarantine strategy in Korea.
The Central Defense Response Headquarters (Bang Dae-bon) announced on the 14th that of the remaining 1,440 serum samples collected from June 10 to August 13, neutralizing antibodies were confirmed. The serum to be studied was collected in 13 cities and provinces across the country, including Daegu. The serum from the Daegu area was 145 cases, or 10.1% of the total.
This survey was also conducted after the 1st National Health and Nutrition Survey published by Daebon Bang on July 9, after the residual serum antibody level was investigated. In the first time, only one of the 1,555 sera collected from April 21 to June 16 showed no neutralizing antibodies. At that time, there were observations that the retention rate would be higher when included in the collection sample because there was no serum from the Daegu region, but there was no significant difference. Neutralizing antibodies were found in just one sample in the antibody titre survey conducted by quarantine authorities on 1,500 serum samples collected May 25-28 from patients visiting a medical institution in southwest Seoul.
The low rate of antibody retention in Korea is assessed because it suppressed the spread of the virus largely through social distancing from the start of the crisis. According to the Global Antibody Retention Survey, China Wuhan was 3.2%, Japan Tokyo 0.1%, US New York 14.9%, UK London 17%, Spain the entire region 5%, Sweden Stockholm 7.3%.
Lee Jae-gap, professor at Hallym University School of Medicine (department of infectious medicine), said: “It has been confirmed once again that it is a quarantine strategy that cannot be adopted by herd immunity because the rate antibody retention is very low. ” You have to go out and hold on ”.
Quarantine authorities will continue to investigate the antibody retention rate using the remaining samples from the National Health and Nutrition Survey conducted annually on 10,000 people. It is also planning a survey of 3,300 people, including the general public and medical personnel in the Daegu and Gyeongsan areas of the outbreak area. To confirm the national level of antibody retention by region, 10,000 people in the military and 10,000 representatives from the region will also conduct an antibody survey.
