Chicken Response

• Vaccination Protocol: Birds carrying MDAs against both HVT and Asian H5N1 HPAIV were vaccinated on the first day of age with rHVT-H5, with or without boosting vaccination by an inactivated vaccine after 10 days (Rauw et al., 2012).
• Vaccine Immune Response Type: VO_0000287
• Challenge Protocol: The different groups were challenged with two antigenically highly divergent Egyptian dade 2.2.1 H5N1 HPAIVs at 4 wk of age (Rauw et al., 2012).
• Efficacy: Protection against challenge was compared with unvaccinated birds or vaccinated birds without MDAs. Between 70% and 90% clinical protection could be observed in the vaccinated groups possessing MDAs, indicating no or very low interference of MDAs with vaccination (Rauw et al., 2012).
