Serum HI antibodies (box plots: 25 – 75 percentile) against both the H5 and H7 AI proteins induced by in ovo vaccination on day 18 of embryonation with AdTW68.H5 and subsequent intramuscular vaccination with AdChNY94.H7 on day 27 after hatch. A significant increase (P<0.0001) (Mann Whitney test) of H5-specific antibody was detected between days 27 and 52 after hatch. Similarly, AdChNY94.H7 intramuscular vaccination also determined a significant increase of H7 antibody (P<0.0001) between days 52 and 68 of age. All control birds produced no measurable AI antibody titers (not shown)
