The data from this study suggests a positive correlation between age and NAbs titers. Elderly patients plasma samples showed significantly higher levels of spike-binding antibodies, targeting S1 and S2 compared to young patients. Furthermore, at the time of admission, elderly patients had higher blood CRP levels and lower lymphocyte counts which might suggest that the high NAbs levels in this group of patients can be due to a stronger induced innate immune response. However, there was no difference between patients' ages and the time they spent recovering in the hospital.
