Covid 19 Patients With Mild Cases Still Have Antibodies 11 Months After Infection Study Suggests: Antibodies found in corona patients up to 11 months later, may receive life-long safety: research
- There is a very good news from America for the world that is suffering from the corona virus.
- Recent research has shown that antibodies persist for up to a year in mild case of corona
- Researchers have said that corona antibodies perish very quickly, it is misleading to say
There has been a lot of good news from America for the world that is suffering from the corona virus. A recent research has shown that antibodies to the corona virus’s mild cases persist for about a year after infection is eliminated. Researchers at the University of Washington’s School of Medicine have said at the beginning of the epidemic that corona virus antibodies perish very quickly, which is misleading.
Researchers said their investigations suggest that the immune cells present in bone marrow are still making antibodies while their levels have fallen inside the bloodstream. Research results have shown that antibodies that neutralize the virus are still present after 7 to 11 months in patients suffering from corona. The research team also said that this antibody can provide life-long protection.
‘It is normal for antibodies to go down after severe infection’
Senior author of the research, Dr. Ali Illebedi, said, “There have been earlier reports that antibodies cease only a few days after infection and the mainstream media has taken it to mean that immunity does not last long.” But this was a misinterpretation of data. After severe infection it is normal for the antibody level to go down but it does not reach the level of zero. Antibody stabilizes. ‘
Professor Ali Illebadi said that in our research, we found that antibody-forming cells persist in the patient for 11 months after the first symptoms. These cells will remain alive and will make antibodies throughout the life of the person. This is a strong evidence of the continuity of immunity for a long time. Immune cells that survive for a short period of time during infection are rapidly formed so that antibodies that provide early protection can enter the body.
‘Safety can last a lifetime in patients with mild infection‘
He said that these immune cells are called long-lasting plasma cells. It remains in reserve after infection. Professor Ali Ilabedi said that most of these plasma cells go inside the bone marrow. The research, published in the journal Nature, included 77 people with mild infections. Of these, only 6 people were admitted to the hospital. Volunteers gave their blood samples every three months.
Research found that although the level of antibodies fell in the first few months of infection, it did not end. These antibodies stabilized. Antibodies were detected in these patients even after 11 months. The research team said that people who have a mild infection of corona virus can have life-long protection. It is also possible that people with severe infection with corona virus will have less protection.
