From: A stronger antibody response in increased disease severity of SARS-CoV-2
Antibody IgG-S1 serum titers in 238 individuals who recovered from COVID-19 according to hospitalization at 386 days after primary infection. A comparison of the median level of serum IgG-S1 antibodies between samples from the Mild Group (blue box) and the Severe Group (green box) demonstrated higher serum IgG-S1 titers among patients from the Severe Group at all collection times analyzed over the 386 days A drop in serum IgG-S1 titers was observed in both groups during the follow-up period of the study. OD ratio: denotes ratio between the absorbance level of the patient’s sample by the absorbance level of the calibrator
