Spearman correlation coefficient between serum titers according to age = 0.298. Although there was a weak correlation between increasing age and humoral IgG-S1 response (Spearman correlation = 0.298), we noted that individuals aged over 45 years presented significantly higher median levels of IgG-S1 when compared to younger individuals (Table 2). OD Ratio: denotes ratio between the absorbance level of the patient's sample by the absorbance level of the calibrator
