An HIV-1 DNA prime vaccine, with a recombinant adenovirus type 5 (rAd5) boost, failed to protect from HIV-1 acquisition. We studied the nature of the vaccine-induced antibody (Ab) response to HIV-1 envelope (Env). HIV-1-reactive plasma Ab titers were higher to Env gp41 than to gp120, and repertoire analysis demonstrated that 93% of HIV-1-reactive Abs from memory B cells responded to Env gp41. Vaccine-induced gp41-reactive monoclonal antibodies were non-neutralizing and frequently polyreactive with host and environmental antigens, including intestinal microbiota (IM). Next-generation sequencing of an immunoglobulin heavy chain variable region repertoire before vaccination revealed an Env-IM cross-reactive Ab that was clonally related to a subsequent vaccine-induced gp41-reactive Ab. Thus, HIV-1 Env DNA-rAd5 vaccine induced a dominant IM-polyreactive, non-neutralizing gp41-reactive Ab repertoire response that was associated with no vaccine efficacy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4562404/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4562404/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Williams, Wilton B -- Liao, Hua-Xin -- Moody, M Anthony -- Kepler, Thomas B -- Alam, S Munir -- Gao, Feng -- Wiehe, Kevin -- Trama, Ashley M -- Jones, Kathryn -- Zhang, Ruijun -- Song, Hongshuo -- Marshall, Dawn J -- Whitesides, John F -- Sawatzki, Kaitlin -- Hua, Axin -- Liu, Pinghuang -- Tay, Matthew Z -- Seaton, Kelly E -- Shen, Xiaoying -- Foulger, Andrew -- Lloyd, Krissey E -- Parks, Robert -- Pollara, Justin -- Ferrari, Guido -- Yu, Jae-Sung -- Vandergrift, Nathan -- Montefiori, David C -- Sobieszczyk, Magdalena E -- Hammer, Scott -- Karuna, Shelly -- Gilbert, Peter -- Grove, Doug -- Grunenberg, Nicole -- McElrath, M Juliana -- Mascola, John R -- Koup, Richard A -- Corey, Lawrence -- Nabel, Gary J -- Morgan, Cecilia -- Churchyard, Gavin -- Maenza, Janine -- Keefer, Michael -- Graham, Barney S -- Baden, Lindsey R -- Tomaras, Georgia D -- Haynes, Barton F -- P30 AI064518/AI/NIAID NIH HHS/ -- P30-AI-64518/AI/NIAID NIH HHS/ -- U01 AI069412/AI/NIAID NIH HHS/ -- UM1 AI068614/AI/NIAID NIH HHS/ -- UM1 AI068618/AI/NIAID NIH HHS/ -- UM1 AI068635/AI/NIAID NIH HHS/ -- UM1 AI069412/AI/NIAID NIH HHS/ -- UM1 AI069470/AI/NIAID NIH HHS/ -- UM1 AI069481/AI/NIAID NIH HHS/ -- UM1 AI069511/AI/NIAID NIH HHS/ -- UM1 AI100645/AI/NIAID NIH HHS/ -- UM1AI068618/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2015 Aug 14;349(6249):aab1253. doi: 10.1126/science.aab1253.
