AstraZeneca may have provided incomplete efficacy data NIAID

So the issue is that they've included too much data leading to (in the DSMB view) inaccurate efficacy rather than incomplete data.
Nonetheless this is a management failure on their part because any disagreement with the DSMB over which data to include should have taken place privately before publication of the results. For all I know they have good reason for including this older data but it's not a good look to have your DSMB disagree with you in public now.
There are serious issues in both directions here.
I also don't see a prevailing reason why one of the vaccine companies would want to sabotage AZ. They're all at maximum production afaict, and AZ had worse efficacy than Moderna already. If it were corporate sabotage, I would expect them to target one of the superior mRNA vaccines.
AZ is also the one that screwed up here. If they can't submit correct efficacy data, people should be concerned. That raises serious doubts about their internal organization, and looks like we may be relying on government safety regulations to ensure the vaccine is safe. Which were relaxed for this vaccine.
I didn't see a lot of people saying we should keep letting Boeing's MAX keep flying until we could be totally sure that it wasn't just an unlucky streak of drunk pilots. I also don't see a lot of people saying that we should give Boeing lead time to get a PR spin on their latest disaster.
> Media headlines are a really sucky way to do data science.
I agree. They're also the only way that most people are going to encounter this information, which I would argue they have a right to know. I hope that they'll make rational decisions based on the evidence available, but I'd rather they made poor choices with the evidence than good choices without it.
It's my understanding that the EU has a similar concept.
(It's an entirely appropriate use of these regulatory concepts, of course; this sort of pandemic is precisely why they exist.)
This is in addition to the existing powers of article 174, which allows an unlicenced medicine to be rolled out in exceptional circumstances.
Very stupid and unfortunate.
For those reasons, along with the lack of any information as to whether the vaccine has a meaningful effect on reducing transmission, I have decided that the risk (relative to the reward) to me is too high.
> along with the lack of any information as to whether the vaccine has a meaningful effect on reducing transmission
There's substantial evidence coming out on his front. Not enough for the CDC to tweak recommendations yet, but I expect that in the next few months: https://www.reuters.com/article/health-coronavirus-israel-va...
"Data analysis in a study by the Israeli Health Ministry and Pfizer Inc found the Pfizer vaccine developed with Germany’s BioNTech reduces infection, including in asymptomatic cases, by 89.4% and in syptomatic cases by 93.7%."
"More research is needed to draw a definitive conclusion, but the studies are among the first to suggest a vaccine may stop the spread of the novel coronavirus and not just prevent people getting ill."
As you (and the article) say, much more research is needed.
> A separate study by Israel’s Sheba Medical Center published on Friday in The Lancet medical journal found that among 7,214 hospital staff who received their first dose in January, there was an 85% reduction in symptomatic COVID-19 within 15 to 28 days with an overall reduction of infections, including asymptomatic cases detected by testing, of 75%.

edit: This just came across my feed, published today. See Fig 1 for a chart that doesn't need deep stats knowledge to understand.
https://www.nejm.org/doi/full/10.1056/NEJMc2102153#.YFoyawOb...
> As shown in Figure 1A, the percentages of persons who became infected differed according to vaccination status, with infections in 234 of 8969 nonvaccinated employees (2.61%; 95% confidence interval [CI], 2.29 to 2.96), 112 of 6144 partially vaccinated employees (1.82%; 95% CI, 1.50 to 2.19), and 4 of 8121 fully vaccinated employees (0.05%; 95% CI, 0.01 to 0.13) (P<0.01 for all pairwise comparisons).
> The effect of vaccination on the preservation of our workforce has been dramatic. We observed a greater than 90% decrease in the number of employees who are either in isolation or quarantine.
It's right there.
Additionally, perhaps you are better equipped than I to know, but I believe you could control for any risk you perceive (which I think is ridiculous, but to each his own) from having someone inexperienced administering the vaccine by getting it from your GP.
As for the transmission of COVID-19, if you require absolute proof that vaccination will prevent all transmission then you are setting your bar far too high and your position is indefensible.
To start the presumption is that it is very likely that vaccination will at the very least reduce the likelihood of transmission because while there are viruses like Measles that can still be transmitted in such circumstances those cases are the exception to begin with.
Furthermore evidence is building that vaccination against COVID-19 prevents people from carrying loads of the virus that can be transmitted, if you are quite as committed to this line of argument as you seem to be I am sure you can find the published and pre-pub studies out there. I am confident that if you went about booking yourself an appointment for a month from now by the time your appointment were actually up you'd have lots more evidence to avail yourself of - and you'd always have the option of declining at the time!
People don’t trust the vaccine because a lot of them are scientifically illiterate and paranoid. That someone on the Internet sees benefit in hiding something doesn’t factor into the equation. It’s an emotional response, not a fact-based one.
No thanks. Your attitude is a significant part of our current political dysfunction. Public servants have been replaced by self-promoters and technocrats who share nothing except contempt for the man on the street.
We've already seen issues in recent weeks with the blood clots issue, where the initial breathless media coverage gives way to "the regulators took a look and it seems fine, it's about the normal level of them, and the pause probably killed many more than the clots ever did".
Lay people - including reporters - are really bad at teasing apart normal "how the sausage is made" from "there's an actual issue here", especially with anti-vax propagandists ready to leap on anything with even a hint of confusion.

Don't get mad at Fauci over a personal lack of information.
> The findings of these simulations should neither be generalized to the effectiveness of all medical procedure masks or cloths masks nor interpreted as being representative of the effectiveness of these masks when worn in real-world settings.
I think complaints are justified when CDC officials turn around and do exactly what their report says not to do: interpret the findings as being representative of real-world settings. A year in and with trillions spent, our evidentiary standard should be higher.
Turning this sort of CYA language that's standard in medical research into a scary gotcha is exactly the sort of propaganda the anti-vax folks engage in all the time.
I'm very comfortable with a tentative recommendation based on the lab data for a non-dangerous intervention. If we get observational data a year from now confirming it, even better.
In all likelihood the AstraZeneca vaccine is perfectly fine. But we should have this conversation in public. If people "come to the wrong conclusions," that's fine. It's the price we pay for an open society.
Yes, let's, but let's also factor in "how many people die if we pause vaccinations for several weeks and it turns out not to have been an issue".
1. If there's a serious issue with the vaccine and we kept it quiet, the consequences would be catastrophic. Not only in terms of public health but also in terms of public trust. Even a small chance of this outcome far, far outweighs the number of people who will die due to people wrongly deciding not to get the AZ vaccine.
2. We have a moral obligation to have conversations in public that involve the safety of injecting substances into people. Regardless of "cost benefit analysis," people simply have a right to be privy to these conversations. It's better for things to go worse and respect this right than for things to go better and not respect it.
The issue in question is about efficacy, not some unexpected dangerous drug interaction or side effect.
Somewhat lower than expected efficacy wouldn't be "catastrophic".
When you play this utilitarian game, you can kick the consequences can down the road forever, which is why it's better to think of these arguments in more immediate terms.
Absolutely! That's why I said it has to include:
> "how many people die if we pause vaccinations for several weeks and it turns out not to have been an issue"
as a consideration.
When I say immediate, I'm talking about this:
> 2. We have a moral obligation to have conversations in public that involve the safety of injecting substances into people. Regardless of "cost benefit analysis," people simply have a right to be privy to these conversations. It's better for things to go worse and respect this right than for things to go better and not respect it.
I would rather have more people die in an open society than less people die in a closed one.
I think that is a perfectly acceptable trade-off given the the long-term goal of eliminating polio entirely. I also think it's totally ok to ask people to bravely face a risk to help others (a fairly small one in this case). I even think it can be ok to ask minors, and parents, to take on those risks in some circumstances, and I think polio elimination is one of them. But it's a trade-off that must be done openly, with consent.
Exactly this. Journalists and laypeople are specialists in making mountain out of molehills
But it's said when specialists also do that (with the suspension of the vaccine when the thing it is preventing has a 1000x chance of causing the same problem)
It sounds like they're not getting the type of collaboration they want from AZ, so they've raised the stakes.
And it's clear enough that literal anti-vax people don't need a real reason. It's hesitancy that is the addressable issue, which is going to be better addressed by building trust than by saying what sounds right.
Why isn't the data entirely public with every stats student giving it a go?
That sounds like a recipe for a whole bunch of new charts on https://www.tylervigen.com/spurious-correlations to me.
I assume that whatever the discussion, it wasn’t going to get resolved quickly so the FDA informed AZ they could not sit on the information and would have to make a public statement.
The actual final data analysis isn’t done (AZ mentioned this in their press release). It sounds like they did an initial analysis of the final data, it looked similar to the Feb interim data, so they said “good enough, go with 79% in the press release” and the FDA was like “wait a second, that wasn’t the agreed upon final data”.
https://www.astrazeneca.com/content/astraz/media-centre/pres...
Instead they've now caused another round of noise.
AZ's vaccine has been proven safe and effective multiple times in multiple studies.
The FDA has banned banned everyone from choosing to voluntarily get it if they wish. It's not based on ANY bona-fide scientific concern, it's ban is solely based on red tape. This event proves it. If the FDA was in the business of helping people, they would find a way to lift this ban.
Either one of two things has happened:
1) Their independent DSMB have conspired to screw them for reasons unknown - I think this is pretty unlikely.
2) They have mismanaged the communications with the DSMB and released results which it was their job to know the DSMB did not agree with.
Something not being approved is not the same thing as a ban. You and I might think there is enough evidence, given the context of the pandemic, to have started using this vaccine in the US but I am not qualified to assess that.
This worked fine for Pfizer, Moderna, and Johnson & Johnson.
The above sentence, for me, sums up the quality of this article: What poll?
Somehow, I’d still take the vaccine. I remain convinced that none of this is done with malicious intend.
But that confidence is based mostly on a general trust of institutions and procedures in healthcare. It’s a deep reservoir of trust, built up over time. AZ is certainly taking from it more than it is contributing.
It reads like a smear campaign.
This wouldn't be the first I have seen News Agencies deliberately avoid carrying comments because the PR on the other side of the table happened to not respond "immediately" or "in time" etc;
> The DSMB expressed concern that AstraZeneca may have included outdated information from that trial, which may have provided an incomplete view of the efficacy data
[because... the data reviewed does not appear to cover the California varient, etc...]
The fact that it is kept vague and not including a reason is not helpful and leads to speculation on how terrible AZ are for not being able to submit proper data. They do confirm that this question has nothing to do with the blood clots which this data helps disprove any proper link.
Otherwise, keeping things vague provides maximum room for maneuver for both groups to resolve the issue without either group losing too much face. This way things can get chalked up to "mis-understandings" of what the requirements were, and AZ can reclarify their data in light of these new requirements.
What’s going on over at AZ? I’m not claiming conspiracy, but clearly there was a miscommunication somewhere.

“We will immediately engage with the independent data safety monitoring board (DSMB) to share our primary analysis with the most up to date efficacy data. We intend to issue results of the primary analysis within 48 hours.”

“Pfizer argued that it was not required to obtain informed consent for experimental drug trials in Africa, and that any case should be heard in Nigeria”
From the Wiki article
>Pfizer subsequently settled the case out of court with a $75 million settlement that was subject to a confidentiality clause.
Does the confidentiality clause also suppress media or is that a separate payment to whoever is putting their nose into it? I'm curious how these stories get out, and are there others that don't ever reach Wiki articles?
Unfortunately, it’s the related stuff, manufacturing, procurement, trials, contract signing, that was done by AZ and they have almost entirely done a horrible job.
They failed for 8 years to get this particular vaccine platform to work, and read some of the other comments, they probably caused more of the infamous string of clinical trial screw ups than AZ.
There is an excellent investigative report by Le Figaro (in French) that details the many issues the vaccine faced:
https://www.lefigaro.fr/sciences/astrazeneca-le-laboratoire-...
These include friction between AZ and Oxford, the latter insisted on retaining much more control than they would normally have, and this led to serious flaws in the design of experiments for the trials, including not having sufficient numbers of over-65. Furthermore, they mixed samples with different inoculation protocols, raising all sorts of red flags within the scientific community. It does seem the vaccine is effective and safe, but the unforced methodology errors did them no favors, and explain why the FDA and EMA are taking an exceptionally hard look at the data.
Furthermore, production is outsourced to a number of companies with varying level of expertise, and they are poorly supervised by AZ, for instance EU commissioner Thierry Breton performed an inspection in the Belgian subcontractor that has been having problems that led to AZ not meeting its contractual commitments to the EU (and a diplomatic crisis between the EU and UK), and found production and quality control issues the AZ headquarters were unaware of.
In my eyes the fact that so much of vaccine production is in private hands is a classic example of "privatising profits" because everyone paid for the research with their taxes.
Gates is a super billionare only looking out for his bank account, through the good old "philantrophy PR" scheme. He is actively doing class warfare by close sourcing vaccines. Completely in line with the rest of his endeavours.
Something fishy is going on. Either at AZ or from the outside.
Here in my country PM claimed to never accept Sputnik. Wonder what will happen if EU confirms it :)
[1] https://www.handelszeitung.ch/unternehmen/schweizer-biopharm...
The concerns about Sputnik are geopolitical in nature (weakening the sanctions regime against Russia for its doings in Ukraine, and the persecution of Navalny), not sanitary ones.
Not entirely. Their politicians boasted about it being the world's first "registered" vaccine a month before its Phase III trial started, that was an own goal completely of their making. It was only months later where they were able to finish their Phase III trial with very good results, but a few weeks behind the two mRNA vaccines.
That said, the effectiveness of Sputnik V has been established to Western standards now, so the only reason for the EU to refuse it when it is in crying need for vaccines is political, not scientific or medical.
That's not what this means.
AZ has genuinely fucked up a couple times. They accidentally gave some trial participants half the intended dose (https://www.bbc.com/news/health-55086927), and now appear to have made a mistake in reporting data.
They're procedural fuckups. Never should've happened, but neither one inherently says "the vaccine is unsafe".
That was an Oxford fuck up, as were most of the other early clinical trial ones as far as we know. As others have explained, this is not a normal small organization plus Big Pharma arrangement, and after the EU went crazy I'll bet AZ is now regretting ever getting involved.
AZ's catastrophic fuck up from that testing mistake which should have burned a lot of their credibility was to use that data which in the long term didn't pan out to make a blended claim of higher efficacy than they could at that time legitimately support.
Basically what seems to have happened is that Oxford university developed the vaccine, required that companies who wanted to manufacture and sell it should not make a profit, and therefore only got companies with little vaccine development experience, such as AstraZeneca, which probably due to their lack of experience has been making mistake after mistake.
That being said, we have seen that with COVID the vast majority of vaccines have been extremely successful (some like the Russian and Chinese ones were deployed without complete testing and were shown to have great results), and since we are confident the AZ vaccine is safe enough, ans we can see the impact in the UK, there’s a strong justification to authorize using it even without proper results.
Just not in the US, which already has access to enough vaccines for its population without needing the AZ zone.
Although I disagree that there was any reason to hold up UK approval, there was clear safety and effectiveness evidence that overwhelmed any doubts about safety in spite of the screw ups.
But I have zero sympathy for AZ even if many, many people are compounding their errors.
"This manufacturer has never released an approved vaccine"
and
"This manufacturer is not allowed to make a profit on this product, so there is no monetary incentive to ensure quality after the product is authorized for emergency use"
I fully expect the same quality as soviet era cars.
Hilariously Lada cars - the Soviet era cars being referenced I expect - were exported for the express purpose of making a profit!
What's Pfizer's reputation? Seems to be fine among the masses, despite decades of mismanagement and killing people.
The fact that, even when lives are at stake, companies cannot resist temptation, is why there are regulations. Try complaining about the regulations that were relaxed to allow this all to happen, however, and suddenly I'm an anti-vaxxer.
Am no super smart virologist but my brain immediately pinged when I started hearing the news from AZ quoting ... 100% effective against Xxxxx...
Only thing that came to me was the good ol' adverts from bug sprays and disinfectants claiming to be 99.9% effective against bugs/bacteria
This is an illustration of why lay people applying "common sense" to data sets and statistics can be a problem.
The efficacy stats are based on small numbers, but with sound stats behind them. For example, from https://www.nytimes.com/interactive/2021/03/03/science/vacci...:
> What’s more, all the vaccines look as if they have a high efficacy against more serious outcomes like hospitalization and death. For example, no one who got Johnson & Johnson’s vaccine had to go to the hospital for a Covid-19 infection 28 days or more after getting an injection. Sixteen people who got the placebo did. That translates to 100 percent efficacy, with a confidence interval of 74.3 percent to 100 percent.
Expanding from the trials (with tens of thousands of people) to billions of people will mean that number can't stay at 100% forever in real-world use. It's still a great number to see.
IMO the 100% effective xxx was absolutely unnecessary. It becomes easy for anyone to tear down this report. AZ aren't helping themselves with such claims.
Also prefer they round off nothing. Report your data as-is. Majority of the people aren't stupid. They don't need your loose interpretations nor any nudges. Certainly not from the vax manufacturer.
And if am not wrong, they should be publishing the final report based on this research.
> There were no hospitalisations in the ChAdOx1 nCoV-19 group after the initial 21 day exclusion period, and 15 in the control group.
You can disbelieve it, if you like, but you can hardly accuse them of not publishing it.
