Viraemia detected by qRT-PCR and virus titration. Cycle threshold values (Ct values) of whole blood for all groups during the challenge period are displayed in Figure 3A. Results of blood titration for all groups during the challenge period are given in Figure 3B in log₁₀ tissue culture infection dose 50 per mL (TCID₅₀/mL) whole blood. Data are presented in a box-and-whisker plot, where the ends of the whiskers represent the minimum and maximum values, respectively. Outliers are represented as points instead of whisker-ends. The box includes 50% of the values of each group and the line in the middle of each group represents the median value of each group. The level of viraemia measured in Ct values was significantly lower in all vaccinated groups than in the control group (yellow). In contrast, duration of viraemia was only shortened significantly in the group vaccinated three times with Recombitek® (dark green).
