Newcastle disease virus-based vectored vaccine

Abstract

Provided are compositions and methods for vaccinating against picornaviruses. The compositions include modified Newcastle Disease viruses (NDVs) that are sufficient to produce virus-like particles (VLPs) in a host recipient. The modified NDVs contain a single stranded negative sense RNA polynucleotide having nucleotide sequences configured in a 3′-5′ direction encoding sequentially NDV nucleocapsid protein (NP), phosphoprotein (P), matrix protein (M), fusion protein (F), hemagglutinin-neuraminidase (HN) and RNA-dependent RNA polymerase (L) protein. A first nucleotide sequence encoding a picornavirus capsid polyprotein precursor is positioned between the between P and M nucleotide sequences. A second nucleotide sequence encoding a picornavirus protease that is capable of processing the capsid polyprotein precursor is positioned between the HN and L nucleotide sequences. Purified, infectious non-pathogenic NDV particles are included, as are methods for using such particles for vaccination against any infectious picornavirus. Kits and articles of manufacture containing and/or for making the NDV particles are also provided.
