  • Viable viruses with foreign tags
    Patent number: 10729756
    Abstract: Multiple DIVA vaccines effective against porcine reproductive and respiratory syndrome virus (PRRSV) are disclosed. The DIVA vaccines may be negative DIVAs or positive DIVAs. The DIVA vaccines may be produced by modifying the nsp2 region of a modified live virus vaccine. The modification may be one or more deletions only (negative DIVAs) or a deletion with an insertion (positive DIVAs). The insertion may be of an epitope tag, such as a V5, S-Tag, or FLAG tag. Produced DIVA vaccines may be stable through multiple passes and thus may be effective for production and vaccination of animals.
