Antibodies against the novel corona virus may, after the patient recovers, be ‘rapidly depleted’. This has been claimed in a new study. In this study, more than 250 corona virus infectants were studied for five months after their infection was released.
The study, published in the journal Science Immunology, analyzed 983 samples of blood plasma taken from 79 Kovid-19 patients admitted to hospitals and from 175 other infected patients. According to scientists including Katharina Roltgan of Stanford University in the US, IgG antibodies should have been prolonged, but even in severe patients, a slow decline was observed.
Researchers said based on the results that the levels of various types of antibodies that abolished the corona virus began to fall almost after the first month of symptom onset. He said that these results raise important questions on the authenticity of sero studies.
