Provided are compositions and methods that involve recombinant Newcastle disease viruses (rNDVs) that contain an S protein of infectious bronchitis virus (IBV). The rNDV particles include a contiguous segment of IBV S protein that spans an IBV cleavage site between IBV SI and IBV S2 proteins, and can include a full length IBV S protein. Because the particles are multivalent they also stimulate a protective immune response against NDV infection. The compositions are particularly useful for use with avian animals, such as chickens. Isolated rNDV particles, and vaccine compositions that contain them are also provided.
