The elderly people who have recovered from the corona have more virus-neutralizing antibodies than the young. This result has been revealed in a test of 175 people with mild infection discharged in February from a hospital in Shanghai, China. Researchers say the levels of neutralizing and spike-binding antibodies in plasma from middle-aged to elderly patients were relatively high. Antibody levels were found to be lower than the norm in 30 percent of youth. At ten, his level was so low that it could not be caught. At the same time, antibody levels were high in only two patients.
Could not know the level of infection
Scientists could not get the correct information about the level of infection due to the non-detection of viral DNA from the samples of the patients. Therefore, it was not clear whether the antibodies were low due to mild infection in the youth.
Equal period of recovery
Scientists are also surprised by many revelations in research. Indeed, the elderly did not recover well even after having more antibodies. That is, elderly and young patients took a similar time to recover. The average duration of illness of these cured people was 21 days, the average time of hospitalization was 16 days and the average age was 50 years.
Strong immunity may occur even in the elderly
Scientists say that higher levels of antibodies in the elderly may also be due to their stronger immune system. However, only strong antibodies have not provided strong evidence of preventing them from serious infection because the world over has found that the elderly are more vulnerable to corona.
In-depth research needed to be re-infected
Researchers found neutralizing antibodies for coronavirus in patients within 10–15 days of infection, whose levels remained stable until later. Researchers have suggested the need for intensive studies on the possibility of re-infection due to low antibodies in young patients.
