Figure 3From: Attenuation and efficacy of human parainfluenza virus type 1 (HPIV1) vaccine candidates containing stabilized mutations in the P/C and L genesRepresentation of the relationship between the level of replication of HPIV1 wt and rHPIV1 mutants in AGMs and the subsequent level of replication of HPIV1 wt challenge virus in the immunized animals. The mean peak virus titer (log10 TCID50/ml) in the URT following immunization (y-axis) was plotted for viruses 1–9 (Table 3) against the mean peak challenge virus titers (log10 TCID50/ml; x-axis) in the same groups (Table 4). A curve of best fit has been inserted (solid line) to demonstrate the association between these two data sets.Back to article page
