Eleven-year individual change of respiratory virus-specific IgG levels, from childhood to early-adulthood
Among the 270 participants with respiratory virus-specific IgG levels measured both during childhood in EGEA1 and early-adulthood in EGEA2 (about 11 years later), the specific levels of IgG significantly decreased over time for each RV species, with a lower magnitude for RV-B as compared to RV-A and RV-C (Figure S6). These results were similar after adjustment for age at baseline, sex, BMI, tobacco smoke exposure, season of blood sampling, allergic sensitization and ever-asthma (Table 3). A similar trend was observed for RSV (p=0.09).
