Antibodies Cross-Reactive with Bundibugyo Virus in Ferrets Vaccinated with Ebola Virus Vaccine
Figure 2

Figure 2. Endpoint titers of EBOV glycoprotein– and BDBV glycoprotein–specific IgG in rVSV-EBOV– vaccinated ferrets and controls in study of antibodies cross-reactive with BDBV in ferrets vaccinated with EBOV vaccine. Serial dilutions of serum were assayed by indirect ELISA. Date shown are reciprocal endpoint titers exceeding the cut-off value of the mean plus 3 times the SD of the 1:400 dilution of prevaccination serum collected from all ferrets. Horizontal colored lines represent the mean reciprocal endpoint titers. The dashed line at a reciprocal endpoint titer of 400 represents the lower limit of detection of the assay. BDBV, Bundibugyo virus; EBOV, Ebola virus; rVSV-EBOV, recombinant vesicular stomatitis virus–based vaccine encoding the Ebola virus glycoprotein.
