The results of the study raise doubts on the idea of a long-term immunity. In addition, they could depend on the Severity of the infection.
According to a new study, patients with few symptoms or a symptom-free course of a Corona-disease form a lower immunity than severely Ill.
The investigation of Chinese researchers was published in the journal “Nature Medicine”. On the basis of samples of 74 and diseased people of the metropolis of Chongqing, you made the differences.
Weaker immune response to the Coronavirus
Three weeks after infection showed that 62.2 percent of the symptom-free group had antibodies in the blood. In the symptomatic group were 78.8 per cent. After eight weeks, a far more drastic decline of antibodies in symptom-free patients (by 81.1 percent) proved to be the sympomatischen. (62.2 percent).
In addition, were found in the case of the former, less of the immune system involved in cell proteins, suggesting a weaker immune response to the Coronavirus close. Thus, the study presents the idea that everyone is against Corona-immune, if he had it once, out of the question. The immunity could, therefore, be only of short duration.
