Science is fully retracting the Report “Detection of an infectious retrovirus, XMRV, in blood cells of patients with chronic fatigue syndrome”.
He writes that the decision was reached because multiple laboratories have failed to reliably detect XMRV or related viruses in CFS patients. He also cites evidence of ‘poor quality control in a number of specific experiments in the report’, and that Figure 1, table S1, and figure S2 have been retracted by the authors. Finally, he notes the omission of information from the legend of figure 2C, specifically that the authors failed to indicate that the peripheral blood mononuclear cells had been treated with azacytidine, phytohemagglutinin, and IL-2. He concludes:
Given all of these issues, Science has lost confidence in the Report and the validity of its conclusions. We note that the majority of the authors have agreed in principle to retract the Report but they have been unable to agree on the wording of their statement. It is Science’s opinion that a retraction signed by all the authors is unlikely to be forthcoming. We are therefore editorially retracting the Report. We regret the time and resources that the scientific community has devoted to unsuccessful attempts to replicate these results.
