That's certainly an improvement, but even if health authorities and researchers quickly adapt their knowledge to reflect the retraction of this paper, the wide media circulation of "HCQ will kill you" has permanently poisoned the well of test patients for future research.

Even though the retraction was quick, the damage to future research is permanent. If this was in fact a propaganda operation rather than just incompetence, pride and an unethical career gambit, it was an incredibly successful one.

When someone fakes data to this degree, in a case that has this level of immediate real-world impact, one has to question the motivation behind it. Hope this gets illuminated during the investigation, but I'm not holding my breath.
