A newly published study from researchers at Mount Sinai hospital system in New York shows the "vast majority" of patients with mild-to-moderate COVID-19 symptoms have antibodies for at least three months. Plasma from 121 donors was observed by the researchers to determine how long the antibodies responded to the spike proteins in SARS-CoV-2. The researchers noted that understanding mild COVID-19 cases is important since it's widely believed that mild and asymptomatic patients make up the vast majority of cases. A separate study from researchers at St. George’s, University of London found antibodies could remain stable in an infected person's blood for two months after diagnosis. The study also found antibodies were not detected in all of the participants.
