Article Synopsis
- The study examined immune responses in the Harderian gland of SPF chickens and commercial chickens after vaccination with Newcastle disease virus (NDV) LaSota via ocular route.
- SPF chickens showed a continual increase in serum antibodies 15 days post-vaccination and a notable IgA response in lacrimal fluids within 10 days.
- In contrast, commercial chickens with maternally derived antibodies exhibited strong IgA responses in lacrimal fluids after vaccination at 2 days of age, but no serum response until 15 days, indicating the importance of maternal antibody waning for effective vaccination.
Understanding gene expression changes in chicks after vaccination against Newcastle Disease (ND) can reveal vaccine biomarkers. There are limited data on chicks' early immune response after ND vaccination. Two trials focused on this knowledge gap.
