The ISG and IFN responses in chickens vaccinated with LAIV or IIV at 1 day of age.

<p>(A) Trachea tissue at 1 dpv. (B) Trachea tissue at 3 dpv. (C) Spleen tissue at 1 dpv. (D) Spleen tissue at 3 dpv. The bars represent Log₂ fold change in transcription level of ISGs and IFN genes. Error bars represent mean±SD (n = 5 birds per group). Asterisks without horizontal bar indicate significant differences compared with unvaccinated group. Horizontal bar with asterisks indicates significant difference between LAIV and IIV (<i>*p<0</i>.<i>05</i>, <i>**p<0</i>.<i>01</i>). dpv = days post-vaccination.
