A concern was raised that the Vietnamese healthy volunteers examined in the study did not provide written consent. Subsequent investigation has revealed that for these healthy volunteers, only oral and not written consent was obtained; however, this practice was consistent with regulations at the time. The authors mistakenly cited approval by the Oxford Tropical Research Ethics Committee (OxTREC) for this study. Current regulations by Oxford University now stipulate that all human studies obtain institutional approval, and the regulations now require written consent (http://www.admin.ox.ac.uk/researchsupport/ctrg/furtherinfo/).
