The infectious cDNA clone of commercial HP‐PRRS JXA1‐R‐attenuated vaccine can be a potential effective live vaccine vector
18 Apr 2020
Abstract excerpt
Multiple commercial porcine reproductive and respiratory syndrome (PRRS) modified live vaccines are currently utilized in Chinese swine herds due to the limited cross-protection of vaccines and coexistence of different PRRS viruses. In this study, an infectious cDNA clone of the highly pathogenic PRRS (HP-PRRS) vaccine JXA1-R strain was generated. We successfully rescued the virus from direct in vitro DNA...
