Fuente: WIPO "tomato" Described in certain example embodiments herein are compositions, such as immunogenic compositions that can contain or more viral polynucleotides and/or polypeptides. In some embodiments, the one or more viral polynucleotide is a non-canonical viral open reading frame (ORF). Also described herein are methods to identify one or more viral polynucleotides and/or polypeptides such as a non-canonical viral ORF, such as massively parallel ribosome profiling.
