COVID-19 is caused by SARS-CoV-2, and this study explores the levels of neutralizing antibodies (NAbs) in patients over a three-month period after symptoms begin.
Antibody levels were low during the first week but peaked around 33 days post-symptom onset, with a significant majority showing a gradual decline in NAb levels over three months.
NAb levels were found to be positively correlated with immunoglobulin G (IgG) and specific proinflammatory cytokines, indicating a relationship between immune response and antibody dynamics.
