The control of African Swine Fever (ASF) has been hampered by the unavailability of vaccines. Experimental vaccines have been derived from naturally occurring, cell culture-adapted, or genetically modified live attenuated ASFVs; however, these vaccines are only successful when protecting against homologous viruses. We have constructed a recombinant Δ9GL/ΔUK virus derived from the highly virulent ASFV Georgia 2007 (ASFV-G) isolate by deleting the specific virulence-associated 9GL (B119L) and the UK (DP96R) genes. In vivo, ASFV-G Δ9GL/ΔUK administered intramuscularly to swine even at relatively high doses (106 HAD50) does not induce disease. Importantly, animals infected with 104 or 106 HAD50 are solidly protected against the presentation of clinical disease when challenged at 28 days post infection with the virulent parental strain Georgia 2007."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rationally developed african swine fever attenuated virus strain protects against challenge with parental virus georgia 2007 isolate","description":"African swine fever virus (ASFV) is the etiological agent of a contagious, often lethal viral disease of domestic pigs.
