<p>Serum samples from immunized chickens before challenge collected at day 20 (MDA-) or 21 (MDA+) after vaccination with chNDVFHN <sub>PMV8</sub>H5 were tested for NDV (A), APMV-8 (B) and AIV H5 (C) specific antibodies by HI test. Furthermore, serum samples of MDA- chickens and MDA+ chickens vaccinated at day one (MDA+a) or day 7 (MDA+b) after hatch, taken 14 dpch were tested for AIV H5 (D) specific antibodies by HI assay. The number of animals considered seropositive (HI titer > 2 log<sub>2</sub>) is given below box plots. Significant differences (P < 0.05) between C and D are marked by *.</p
