Figure 1.

Vaccinees show ELISA titers comparable to dengue-naive individuals. End-point titers of DV-1 to DV-23, a positive control (2 readings), and a negative control (2 readings) were determined for A) UV-DENV ELISA, B) E protein ELISA, and C) EDIII ELISA of all 4 serotypes. The same data are also represented as OD450 (sample) divided by the OD450 value of the positive control on the same plate for D) UV-DENV, E) E protein, and F) EDIII. The dotted lines indicate the ratio for the negative control for each serotype and provide a cut-off for the respective readouts. The color of the dotted line corresponds to the color of the respective serotype.
