A recombinant Newcastle disease virus-vectored multi-epitope vaccine confers protection against QX-like infectious bronchitis virus in chickens
Infectious bronchitis virus (IBV) QX-like (GI-19) genotype dominates global poultry flocks, yet Mass-type vaccines fail to confer cross-protection. We developed a recombinant Newcastle disease virus (NDV) LaSota vector expressing conserved IBV S1 B-cell hotspots paired with S1-derived BF2-restricted CTL epitopes (rND...
