Complement is activated during passive immunization independent of viremia. Plasma levels of complement components were measured before and after the infusion of a mix of MAbs 2G12, 2F5, and 4E10. Levels of C3 before infusion (open circles) and after infusion (closed circles) are shown for patient NAB11 (A) together with the viral load (solid line) for weeks 1 to 11. Shaded areas indicate complement activation. Median levels of C3 (B), C3a (C), and TCC (D) before (open symbols) and after (closed symbols) infusion are shown for all 14 patients. Error bars show 95% confidence intervals.
