Cloacal virus shedding among vaccinated and non-vaccinated birds at different time points post challenge.
| Time Points | LaSota Vaccine | mIBS025 Vaccine | Control | ||||
|---|---|---|---|---|---|---|---|
| Number of Positive/Total | Virus Copy Number Mean (log10) ± SD | Number of Positive/Total | Virus Copy Number Mean (log 10) ± SD | Number of Positive/Total | Virus Copy Number Mean (Log 10) ± SD | ||
| 3 dpc | 10/10 | 7.38 ± 0.36 * | 10/10 | 6.17 ± 0.40 * | 10/10 | 10.09 ± 0.09 | |

Values with * differ significantly with control within the same time point while those with a differ significantly with the LaSota group. NS = no survived chickens. ND = No virus shedding detected.
