Scientists from the Mount Sinai Medical Center in the United States conducted a study involving more than 30 thousand people who have had coronavirus and established the shelf life of antibodies to COVID-19.
The findings were published in Science on October 28.
Scientists noted that the vast majority of mild to moderate COVID-19 infections showed sustained antibody formation. At the same time, antibody titers remain stable and active for up to five months.
According to the study, the first immune response of the body was observed in the experiment participants 2-3 weeks after the onset of symptoms of coronavirus infection.
The scientists noted that their colleagues had previously found a significant decrease in antibodies in 40% of cases as early as eight weeks after recovery, but a new study showed that antibodies can persist for up to five months and be relatively active.
On October 31, Nikita Lomakin, the chief investigator of the Central Clinical Hospital, told Izvestia that patients who have had coronavirus completely lose their humoral immunity after 3-5 months. Because of this, the expert intends to be vaccinated with the Russian Sputnik V vaccine, despite the fact that he suffered COVID-19 in August.
On November 2, at the Competence Center of the National Technology Initiative (NTI) led by Alexei Borovkov, they spoke about the forecast for the COVID-19 pandemic until the end of February. The group identified three main scenarios for the development of events: optimistic, medium and pessimistic.
