A recent study conducted by researchers at Harvard Medical School and Massachusetts General Hospital revealed the duration of immunity to the "Corona 2" virus in Covid 19 survivors by four months.
According to the journal "Immunology", to reach the results of the study, the research team collected blood samples from 343 patients infected with Covid-2 virus, most of whom were suffering from severe cases. These blood samples were obtained for a period of up to 4 months after the onset of symptoms.
The researchers isolated the blood plasma and placed it on laboratory dishes coated with a behavioral disorder for the spike protein, which plays a central role in the entry of the Corona virus into the cells. People before the pandemic.
The results showed that IgM levels remained elevated in Covid 19 patients for 4 months and were associated with the presence of equivalent protective antibodies that showed a slight decrease in activity over time.
The researchers concluded that it is very likely that people will be protected for 4 months, indicating basic antibody responses to COVID-19.
