This pandemic, originally detected in Republic of Georgia in 2007, has devastated the swine industry in large geographical areas of Southeast Asia with 14 countries reporting ASF outbreaks since the first documented case was confirmed in the city of Shenyang, Liaoning Province, China, on 3 August 2018. In the absence of any available vaccines, the control of ASF relies on the detection and culling of infected animals. The United States Department of Agriculture recently developed a recombinant experimental vaccine candidate, ASFV\u2010G\u2010\u0394I177L, by deleting the I177L gene from the genome of the highly virulent pandemic ASFV strain Georgia, which efficaciouly protects pigs from the parental virus. Here, the initial studies were extended demonstrating that ASFV\u2010G\u2010\u0394I177L is able to protect pigs against the virulent ASFV isolate currently circulating and producing disease in Vietnam with similar efficacy as reported against the Georgia strain. Comparative studies performed using a large number of pigs of European and Vietnamese origin demonstrated that a minimum protective dose of 10<jats:sup>2<\/jats:sup> HAD<jats:sub>50<\/jats:sub> of ASFV\u2010G\u2010\u0394I177L equally protects animals of both breeds. In concurrence with those results, the onset of immunity in these animal breed showed appearance of protection in approximately one\u2010third of the animals by the second week post vaccination, with full protection achieved by the fourth week post vaccination. Therefore, results presented here demonstrated that ASFV\u2010G\u2010\u0394I177L is able to induce protection against virulent Vietnameese ASFV field strains and is effective in protecting local breeds of pigs as efficiently as previously shown for European cross\u2010bred pigs. To our knowledge, this is the first report showing the efficacy of a Georgia 2007 based vaccine candidate in Asian breed of pigs or challenged with an Asian ASFV strain.<\/jats:p>","DOI":"10.1111\/tbed.14329","type":"journal-article","created":{"date-parts":[[2021,9,28]],"date-time":"2021-09-28T21:34:14Z","timestamp":1632864854000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":130,"title":["African swine fever virus vaccine candidate ASFV\u2010G\u2010<b>\u0394<\/b>I177L efficiently protects European and native pig breeds against circulating Vietnamese field strain"],"prefix":"10.1155","volume":"69","author":[{"given":"Xuan Hanh","family":"Tran","sequence":"first","affiliation":[{"name":"National Veterinary Joint Stock Company (NAVETCO)  Ho Chi Minh City Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thi Thu Phuong","family":"Le","sequence":"additional","affiliation":[{"name":"National Veterinary Joint Stock Company (NAVETCO)  Ho Chi Minh City Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quang Huy","family":"Nguyen","sequence":"additional","affiliation":[{"name":"National Veterinary Joint Stock Company (NAVETCO)  Ho Chi Minh City Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thanh Thuy","family":"Do","sequence":"additional","affiliation":[{"name":"National Veterinary Joint Stock Company (NAVETCO)  Ho Chi Minh City Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Van Dung","family":"Nguyen","sequence":"additional","affiliation":[{"name":"National Veterinary Joint Stock Company (NAVETCO)  Ho Chi Minh City Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cyril G.","family":"Gay","sequence":"additional","affiliation":[{"name":"U.S. Department of Agriculture Agricultural Research Service  Beltsville Maryland USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuel V.","family":"Borca","sequence":"additional","affiliation":[{"name":"Agricultural Research Service U.S. Department of Agriculture Plum Island Animal Disease Center  Greenport New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7894-0233","authenticated-orcid":false,"given":"Douglas P.","family":"Gladue","sequence":"additional","affiliation":[{"name":"Agricultural Research Service U.S. Department of Agriculture Plum Island Animal Disease Center  Greenport New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,10,15]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598\u2010018\u201021575\u20108"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.3390\/v13050765"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.02017\u201019"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.3390\/v8100291"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11427\u2010020\u20101657\u20109"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.2009.0098"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.74.3.1275-1285.2000"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.01058\u201017"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.72.12.10310-10315.1998"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.00554\u201015"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.01760\u201016"},{"key":"e_1_2_9_13_1","unstructured":"OIE.
