New studies show that antibodies to coronavirus can remain in the blood only for 2-3 months after infection.

According to an analysis published in Nature Medicine, antibodies do not stay in the body forever. Researchers from the Wanzhou region compared the immune response of 37 asymptomatic people to the same number of patients with symptoms. The authors found that in people without symptoms, the antibody response was weaker.

In addition, within eight weeks, the level of antibodies decreased to an undetectable level in 40% of people with an asymptomatic course compared with 12.9% of people with symptoms, according to the study. After 3 months, antibodies are not detected in those who have been ill with symptoms.
