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.

The present disclosure provides a system for the expression of target protein in conjunction with enhancer protein. The enhancer protein may be a viral protein that blocks nucleocytoplasmic transport. Also provided are polynucleotides, vectors, and cells comprising target protein and enhancer protein nucleic acid sequences.

Provided herein are compositions of virus like particles (VLPs) of poliovirus (PV) that have one or more stabilizing mutations that confer a higher degree of thermostability to the N-antigenic form of the VLPs. These VLPs are non-infectious, and thus safer for use in vaccine development and administration to clinical subjects.

This invention provides a modified protein encoding sequence containing nucleotide substitutions at multiple locations in the protein encoding sequence, wherein the substitutions introduce rare hexamers. These hexamers may be Frame Dependent, or depleted in only the reading frame, or Frame Independent, or depleted in all three frames. Modified protein encoding se quences of the present invention may include modified viruses useful for vaccines.
