The fact that antibodies to coronavirus persist for up to 5 months is beyond doubt, says Areg Totolyan, director of the Pasteur Research Institute of Epidemiology and Microbiology of Rospotrebnadzor.
According to the scientist, there are similar observations in Russia. "Back in early October, we reported that, according to our data, those who have had COVID-19 antibodies are produced and kept at a high level for 4 months," -. Totolyan told RIA Novosti. He emphasized that so many antibodies are retained in patients who have undergone moderate or severe coronavirus. It is this group that is under observation and it is possible to analyze the duration of the presence of protective cells in the body.
But even when the decrease in the level of antibodies begins, this does not mean the disappearance of immunity. According to the scientist, further "memory cells" and cells that produce antibodies are formed, which should provide immune protection when the virus re-encounters.
Earlier, Science magazine reported that antibodies to coronavirus remain in the body of a sick person for up to five months. This conclusion was made by scientists from the Mount Sinai Medical Center in the United States. Totolyan believes that it was for 5 months that the patients were monitored.
