| FI-BRSV (s.c./i.n.) | 3.45 ± 0.32 | 3.89 ± 0.21 |
| FI-BRSV (s.c./s.c.) | 3.14 ± 0.12 | 4.09 ± 0.19 |
| Saline-BRSV challenge | 0.80 ± 0.27 | 1.71 ± 0.57 |
| Saline-saline | 0.64 ± 0.26 | 0.76 ± 0.32 |
a
Titers were determined after BRSV challenge and are expressed as the mean ± standard error of the mean of log10 values of the reciprocal of the highest dilution resulting in a value of 2 standard deviations above the negative control serum value.
