Respiratory syncytial virus (RSV) IgG levels in children who were RSV IgG seropositive at 1 year (n = 109). Children were separated into three groups based on their likely RSV reinfection. (a) Mean RSV IgG levels in children showing significantly increased IgG levels at age 2 years compared to the 1-year sample (likely reinfection between 1 and 2 years, P < 0·001). (b) Mean RSV IgG levels in children showing no increase in IgG levels during follow-up (no evidence for reinfection, P = 0·878 and P = 0·230). (c) Mean RSV IgG levels in children showing increased IgG levels at 3 years compared to 2-year samples (likely reinfection between ages 2 and 3 years, P < 0·001). The boxes represent the interquartile range (25–75%); the whiskers denote 5th and 95th percentiles; the horizontal lines inside boxes show a median; the dashes show minimum and maximum; N is the number of children in different subgroups.
