Serum HI titers (log2) in broiler chicks immunized with recombinant vaccine and challenged with HPAI in experiment 2. One-day old commercial chicks were vaccinated SQ with PBS (G1), RP-H5 (107) (G2), RP-H5 (108) (G3), or RG-H5 (G4). Birds were challenged with A/turkey/Minnesota/12,582/2015(H5N2) clade 2.3.4.4 HPAI virus at 3 weeks of age. Serum samples were taken on day 0 (Pre) and day 10 (Post) after challenge. Statistical differences are indicated by different lowercase lettering (P < 0.05)
