Description:
Preclinical studies of human immunodeficiency virus type 1 (HIV-1) vaccine candidates have typically shown post-infection virological control, but protection against acquisition of infection has previously only been reported against neutralization-sensitive virus challenges. Here we demonstrate vaccine protection against acquisition of fully heterologous, neutralization-resistant simian immunodeficiency virus (SIV) challenges in rhesus monkeys. Adenovirus/poxvirus and adenovirus/adenovirus-vector-based vaccines expressing SIV(SME543) Gag, Pol and Env antigens resulted in an 80% or greater reduction in the per-exposure probability of infection against repetitive, intrarectal SIV(MAC251) challenges in rhesus monkeys. Protection against acquisition of infection showed distinct immunological correlates compared with post-infection virological control and required the inclusion of Env in the vaccine regimen. These data demonstrate the proof-of-concept that optimized HIV-1 vaccine candidates can block acquisition of stringent, heterologous, neutralization-resistant virus challenges in rhesus monkeys.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3271177/" 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/PMC3271177/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barouch, Dan H -- Liu, Jinyan -- Li, Hualin -- Maxfield, Lori F -- Abbink, Peter -- Lynch, Diana M -- Iampietro, M Justin -- SanMiguel, Adam -- Seaman, Michael S -- Ferrari, Guido -- Forthal, Donald N -- Ourmanov, Ilnour -- Hirsch, Vanessa M -- Carville, Angela -- Mansfield, Keith G -- Stablein, Donald -- Pau, Maria G -- Schuitemaker, Hanneke -- Sadoff, Jerald C -- Billings, Erik A -- Rao, Mangala -- Robb, Merlin L -- Kim, Jerome H -- Marovich, Mary A -- Goudsmit, Jaap -- Michael, Nelson L -- AI002642/AI/NIAID NIH HHS/ -- AI060354/AI/NIAID NIH HHS/ -- AI066924/AI/NIAID NIH HHS/ -- AI078526/AI/NIAID NIH HHS/ -- AI084794/AI/NIAID NIH HHS/ -- AI095985/AI/NIAID NIH HHS/ -- P01 AI095985/AI/NIAID NIH HHS/ -- P01 AI095985-01/AI/NIAID NIH HHS/ -- P30 AI060354/AI/NIAID NIH HHS/ -- R01 AI066924/AI/NIAID NIH HHS/ -- R01 AI066924-05/AI/NIAID NIH HHS/ -- R01 AI084794/AI/NIAID NIH HHS/ -- R01 AI084794-03/AI/NIAID NIH HHS/ -- RR000168/RR/NCRR NIH HHS/ -- U19 AI066305/AI/NIAID NIH HHS/ -- U19 AI066305-05/AI/NIAID NIH HHS/ -- U19 AI078526/AI/NIAID NIH HHS/ -- U19 AI078526-04/AI/NIAID NIH HHS/ -- U19 AI095985/AI/NIAID NIH HHS/ -- England -- Nature. 2012 Jan 4;482(7383):89-93. doi: 10.1038/nature10766.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Vaccine Research, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, Massachusetts 02215, USA. dbarouch@bidmc.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22217938" target="_blank"〉PubMed〈/a〉
