The News Feature “Consenting Adults? Not Necessarily...” (Nature 435, 138; 2005) quoted Xiaomei Zhai, a bioethicist at Peking Union Medical College, as saying: “For AIDS, we have to accept that we have to compromise.” This quote was taken out of context. Zhai was not justifying a general compromise in ethical standards for clinical trials; rather, she was pointing out that the lack of suitable animal models makes it necessary to initiate research directly on human subjects. Nature apologizes for this error.
