Interpretive Summary:

Technical Abstract: We previously demonstrated that overexposing the IBV (infectious bronchitis virus) S2 to the chicken immune system by means of a vectored vaccine, followed by boost with whole virus, protects chickens against IBV showing dissimilar S1. We developed recombinant Newcastle disease virus (NDV) LaSota (rLS) vectoring distinct codon optimized IBV S2 genes (rLS/IBV.S2). The S2 genes were inserted into rLS vectors between the phosphoprotein (P) and matrix (M) genes. Further evidence confirming broad protection conferred by combined vaccination with rLS/IBV.S2 and a commercial attenuated Massachusetts-type vaccine against heterologous challenge will be discussed.
