Disappointing research results.

Chinese scientists have researched how long the immunity following coronavirus infection. It turned out that eight weeks most people the level of antibodies is greatly reduced. Especially quickly it occurs in asymptomatic patients and in 40% of these antibodies does no longer reveal, reports the Chronicle.info with reference to Country.

The employees of the Medical University of Cucina observed 37 patients from the Chinese province Wanzhou with asymptomatic Covid-19. The scientists compared the reaction of their antibodies with the immune response of the infected 37 who showed symptoms. As it turned out, patients without symptoms have a weaker immune response than those who were present pronounced symptoms.

Eight weeks of monitoring the content of antibodies decreased in 81% of asymptomatic patients and in 62% of carriers with symptoms Covid-19. Moreover, the rate of antibodies in 40% of asymptomatic survivors, and 12.9% of people with symptoms of decreased to reviewlenovo level.

From the results of the study showed that re-infection is just a matter of time, as a stable immunity to the virus, especially in asymptomatic ill, is not produced. A temporary immunity last no more than 2-3 months.

These results cast doubt on the fundamental possibility of production of population immunity to coronavirus and complete victory over the SARS-CoV-2. According to the study authors, their work may encourage the world leaders to rethink the introduction of so-called certificates of immunity.
