In this Letter, an administrative error led to the publication of an incorrect version of the Competing Financial Interests (CFI) statement. Although the published CFI statement did reference the authors’ affiliation with D-Gen, it did not contain all of the information provided by the authors about the interests of the company. The CFI statement for this paper as originally published was “J.C. is a Director and J.C. and J.D.F.W. are shareholders of D-Gen Limited, which supplies antibody ICSM35.” The updated CFI statement is “J.C. is a Director and J.C. and J.D.F.W. are shareholders of D-Gen Limited, an academic spin-out company working in the field of prion disease diagnosis, decontamination and therapeutics. D-Gen supplied antibody ICSM35.”
