Viral titers from oral swabs in broiler chicks immunized at one-day of age with recombinant vaccine and challenged with HPAI virus 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. Oral swabs were taken at 2 and 4 days post-challenge. Viral titers are expressed as log10 EID50/ml. Statistical differences are indicated by different lowercase lettering (P < 0.05)
