In the version of this article initially published, the author stated in his response to a letter from Seth Berkley that the results of IAVI's AIDS vaccine trials in Belgium and Germany were “not given to trial subjects and fresh consent obtained.” This is incorrect. The European data were shared with trial subjects in India and they were reminded of their option to withdraw from the trial at any time. The error has been corrected in the HTML and PDF versions of the article.
