Host Response |
Chicken Response
- Vaccination Protocol: 2-week-old chickens were immunized by the oculonasal route in order to evaluate the contribution of each protein to the induction of NDV-specific neutralizing antibodies and protective immunity (Kumar et al., 2011).
- Vaccine Immune Response Type: VO_0003057
- Challenge Protocol: The immunized birds were challenged 21 days after vaccination with virulent NDV via the oculonasal, intramuscular, or intravenous route (Kumar et al., 2011).
- Efficacy: With oculonasal or intramuscular challenge, all three recombinant viruses (rAPMV3, rAPMV3-F, and rAPMV3-HN) were protective, while all unvaccinated birds succumbed to death. However, with intravenous challenge, birds immunized with rAPMV3 were not protected, whereas birds immunized with rAPMV3-F alone or in combination with rAPMV3-HN were completely protected, and birds immunized with rAPMV3-HN alone were partially protected. These results indicate that the NDV F and HN proteins are independent neutralization and protective antigens, but the contribution by F is greater (Kumar et al., 2011).
