Fig. 7. Bamlanivimab serum concentration is contingent on the number of days since bamlanivimab infusion.

Bamlanivimab serum concentration (in μg/mL) at time of first COVID-19 vaccination dose is shown for participants arranged into three groups based on the interval (in days) between bamlanivimab infusion and first vaccine dose, T1. The three groups are T1≤64 days, 64<T1≤85 days, and T1>85 days (n=50, 42 and 43 participants, respectively). Each data point represents a single participant with samples collected ±14 days of the first vaccination dose. Where a participant had more than one qualifying sample, the geometric mean was determined. Boxes and horizontal bars denote the IQR and the median bamlanivimab serum concentration, respectively. Length of whiskers corresponds to 1.5 times the IQR. The dashed black line represents the lower limit of quantification for assay (LLOQ = 10 μg/mL).
