If you look into the background of the company that supplied the critical data it's so obviously fraudulent that it never should have gotten anywhere close to publication.
This study was pure make believe.
That a reputable medical journal published it, and so many policy-makers relied on it, speaks volumes.
If this doesn't cause people in the scientific community to take a hard look at themselves I don't what will.

"We attempt to replicate 67 papers published in 13 well-regarded economics journals using author-provided replication files that include both data and code. Some journals in our sample require data and code replication files, and other journals do not require such files.
Aside from 6 papers that use confidential data, we obtain data and code replication files for 29 of 35 papers (83%) that are required to provide such files as a condition of publication, compared to 11 of 26 papers (42%) that are not required to provide data and code replication files.
We successfully replicate the key qualitative result of 22 of 67 papers (33%) without contacting the authors. Excluding the 6 papers that use confidential data and the 2 papers that use software we do not possess, we replicate 29 of 59 papers (49%) with assistance from the authors. Because we are able to replicate less than half of the papers in our sample even with help from the authors, we assert that economics research is usually not replicable. We conclude with recommendations on improving replication of economics research.

To the original point though, I do think Academic Journals in most disciplines are under serious fire for lazy vetting. It is a shame because so many of these periodicals have real influence on policy making as evidenced by state governments and international agencies relying on this work.
The extremely tough thing about the current debate is the counter-factuals involve life and death. If the research is wrong you might have blocked life saving treatment. If the research is correct then you have pushed magic beans and blocked other lines of treatment or in some historical cases backed harmful treatments.
I know in my professional (Quantitative Finance and Economics), Federal Reserve Researchers put put out a pretty sad research piece showing that even when they were supplied with underlying data and code for research pieces, they couldn't replicate the authors findings.Quote:

That doesn't stop a lot of the work from influencing Central Bank decision makers around the world. The Reinhart Rogoff error is probably one of the most famous.

Yeah, the PhD programs are largely to blame IMO. Tenure drives a publish or perish mentality and professors become desperate to get something/anything out there.
In my field, it took decades to build durable datasets. The University of Chicago's CRISP program has undermined some of the most sacred cows like the Small Cap effect and most recently the Value effect. It was Chicago PhDs that came up with all that stuff, so kudos to them (I suppose) for invalidating their own findings. Still, it is amazing how many strongly held academic views rest of poor quality data and pretty wobbly statistical significance.

Even those that know better can't resist. Remember this blast from the recent past:
"A Prophet of Scientific Rigor - and a Covid Contrarian"
John Ioannidis laid bare the foibles of medical science. Now medical science is returning the favor.
https://www.wired.com/story/prophet-of-scientific-rigor-and-a-covid-contrarian/
Ioannidis has been a fixture in medical-school curricula for years, achieving something akin to hero status. He's one of the most-cited scientists of any type in the world, and may be peerless on this metric among physicians. Amazingly, he's earned all this acclaim by dedicating his career to telling the fields of biomedicine (and others, too) how shoddy they are, and how little trust one should have in their published research.
But now the scientist celebrated for showing colleagues how their studies are screwed up has a new claim to fame. Its very different vibe is reflected in the faces of the medical students I'm addressing. Almost literally overnight Ioannidis has himself become a case study in how to screw up a medical study. And not just any study: This one concludes that Covid-19 isn't all that dangerous; that the current lockdowns to prevent its spread are a bigger threat to public health than the actual disease. In other words, Ioannidis' views on the pandemic sound closer to those of the governor of Georgia than to Anthony Fauci's.

Regarding the HCQ study, I think the jury has pretty much already been in on the efficacy of HCQ on people who are already severely effected. Even the anecdotal evidence for that type of usage is not positive.
The hopes from the beginning for HCQ have been more for effectiveness as a prophylactic or early stage treatment. The Oxford study, since it only concerned hospitalized patients, sheds no new light on that usage.
Regarding the failure a of replicability in published experiments is something that has been observed in other fields as well. There was a study several years ago that found a similar lack of replicability.

It isn't so much as a failure of the peer review process as it is a consequence of failing to peer review. So much of the COVID research has been rushed to publication in preprint form before peer review.FlyRod said:
This was exactly a peer review failure (speaking as someone who knows a tiresome amount about this process).
Please don't interpret the redaction as "hey they drug is ok after all!" It very well might be. But in this case, this article was rushed to publication without thorough vetting.
I am genuinely concerned this fiasco will damage the fight against COVID; people will (rightly) mistrust the scientific peer review process, and it will green light a lot of snake oil (and I'm not referring to the drug in question).
