Top panel: IgG immune responses over time for two vaccinated volunteers from Prevail 1. The solid bent line is the linear interpolation of X = IgG to Ebola GP measured at weeks 0, 1, 4, 26, and 52 (red diamonds). The dotted red line is hypothetical X to reflect Ebola infection. The dashed bent line is hypothetical W=IgG to rVSV vector. The subject infected with malaria arrives with Inline graphic similar to those at infection. Only Inline graphic is similar to the value prior to infection for the Ebola infected volunteer. Bottom panel: a scatter plot of Inline graphic for the controls (circles) with imputation of Inline graphic for the Ebola case (solid square).
