According to the researchers, previous studies had provided conflicting accounts about whether people recovering quickly from the viral infection can sustain potentially-protective antibodies or not. "We've found a subset of individuals that heal quickly while sustaining virus-specific antibody levels after COVID-19," said Duane Wesemann, a co-author of the study from Brigham and Women's Hospital. The researchers collected and analysed blood samples monthly, measuring a range of antibodies, including immunoglobulin-G (IgG), against the novel coronavirus. However, the antibody production remained stable or enhanced in about 20 per cent of individuals over the same time period. According to the scientists, these "sustainers" had symptoms for a significantly shorter period of time compared to "decayers" -- average of 10 days versus 16 days.
