On November 16, last year, at the Daegu Athletics Promotion Center in Suseong-gu, Daegu, members of the Shincheonji Church of Jesus and Daegu Church donated plasma to the third group to develop a treatment for the novel coronavirus infection (Corona 19). Those who participate in this plasma donation are 4,000 members of the Shincheonji Daegu Church who were infected and cured by Corona 19. yunhap news
It was found that about 67% of neutralizing antibodies in the body of patients who were cured after suffering from the novel coronavirus infection (Corona 19) were maintained after 9 months. Neutralizing antibodies neutralize the virus.
According to the Korea Centers for Disease Control and Prevention on the 11th, as a result of investigating the generation and duration of neutralizing antibodies due to Corona 19 infection in 111 cured patients with Corona 19 in Korea, the neutralizing antibody production rate was the same as 78% after 3 months and 6 months on average Appeared. Even after 9 months, the neutralizing antibody was maintained, but showed a tendency to decrease to 67%.
The government is donating plasma from a cure and is conducting research for the purpose of developing a blood system drug and treating severely ill patients. Kwon Jun-wook, head of the 2nd vice-president of the Central Defense Response Headquarters, said, “Of the 4205 people who participated in the plasma recruitment, we obtained consent from 111 subjects for the duration of the antibody survey. “The result of a brief investigation of how long neutralizing antibodies are produced and lasted after infection with Corona 19.”
He said, “The results of this survey are a brief look at the level and duration of natural immunity obtained after corona is confirmed. In the future, the artificial immunity generated through vaccination, that is, the duration of neutralizing antibodies, will be used for comparative studies.”
The duration of the neutralizing antibody of the COVID-19 vaccine is still unknown. Because the development period of all vaccines is less than one year, it has not been confirmed. Experts estimate that the duration of the antibody will be within 6 months due to the nature of the respiratory virus.
“The duration of the neutralizing antibody of the confirmed patient and the duration of the neutralizing antibody of the vaccinated person are different, so it is necessary to conduct a comparative study,” said Um Joong-sik, a professor of infectious medicine at Gachon University Hospital. At this level, I can’t say that even a vaccination person will do this. We need to track and compare the two cases and study them.”
