McChesney %A Christopher J. Miller %J PLOS ONE %D 2012 %I Public Library of Science (PLoS) %R 10.1371/journal.pone.0009814 %X In a previous study, progesterone treatment of female monkeys immunized with live, attenuated SHIV89.6 abrogated the generally consistent protection from vaginal simian immunodeficiency virus (SIV) challenge. The mechanisms responsible for the loss of protection remain to be defined. The objective of the present study was to determine whether Depo-Provera£¿ administration alters protection from intravenous SIV challenge in SHIV-immunized female macaques. %U http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0009814
