    Its only flipping a coin, or 52%, if you completely ignore the fact that the 52% was an average of 0% for the first few days and 90% after a couple of weeks.

    Considering that we know and expect that it will take a few days for the vaccine to start working, and we know and expect that the protection after say 7-8 weeks should be close to the efficacy after 3 weeks, I see no justifiable reason to average those figures together.

    The data for the first ~10 days should be discarded as they're before the vaccine kicks in.

    The 52% is from Pfizer's clinical trials and I have not seen any indication they were "averaging" the efficacy the way you allege.

    He's not really misrepresenting it; it's the overall efficacy for the interval between first and second dose, as reported in their December paper on Comirnaty's safety & efficacy. Almost all cases in the treatment group occurred within first couple of weeks. Problem is, the data is not sufficient to state that efficacy of a single dose is extremely high (from a couple of weeks onward) based on observations over the course of a week and change. Few observations, extremely broad confidence interval, and not necessarily generalizable to present circumstances.

    I've been told in the last few days (by friends and family, and not experts) a couple of interesting things. I don't know whether they are true, so I'll ask here.

    1. If you have a bad reaction to a vaccine (like I did with the AZN vaccine a few days ago), it'll mean you'll get stronger protection from it.

    2. Younger people tend to get harsher reactions because their immune systems tend to be stronger.

    Bullshit or not?

    Europe’s vaccination rollout “has descended into chaos,” as Sylvie Kauffmann of Le Monde, the French newspaper, has written. One of the worst performers is the Netherlands, which has given a shot to less than 2 percent of residents.
    Canada (at less than 3 percent) is far behind the U.S. (about 8.4 percent).
    Within the U.S., many Democratic states — like California, Illinois, Minnesota, New Jersey, New York and tiny Rhode Island — are below the national average. “The parts of the country that pride themselves on taking Covid seriously and believing in government are not covering themselves in glory,” The Times’s Ezra Klein has written.

    The success stories

    At the same time, there are clear success stories in places that few people would describe as progressive.

    Alaska and West Virginia and have the two highest vaccination rates among U.S. states, with Oklahoma and the Dakotas also above average. Globally, Israel and the United Arab Emirates have the highest rates. Britain — run by Boris Johnson, a populist Conservative — has vaccinated more than 15 percent of residents."
    I am not sure this is so much a question of being progressive or conservative, but idiosyncrasies with each state and their rollout plans.

    I heard an interesting story comparing Massachusetts (run by a moderate Republican) and Connecticut (run by a fairly standard to slightly lefty Democrat); MA has done substantially worse in terms of rollout and doses on hand than CT. It sounds like the basic infrastructure exists in each state to get shots into arms relatively efficiently (though not without some embarrassing and avoidable snafus). But MA has held the line on pushing to get the highest priority people vaccinated first, with a particular emphasis on reaching out to communities that are at higher risk but have traditionally been underserved wrt healthcare. CT has opted for a looser approach, resulting in more shots into arms faster - but at the potential cost of those arms being attached to people who are more likely to be white and affluent, precisely the demographics that have been impacted less heavily.

    It's not clear to me what is the better public health choice or ethical choice, and I have a very low opinion of the rollout across the US in general. But it does raise interesting questions about whether a slower pace of shots in arms (at least initially) might potentially yield better public health improvements earlier on. That being said, the biggest success story in the world has had a pretty laissez faire attitude towards relatively loose criteria, with a clear emphasis on doses administered at all cost. But given that they're vaccinating at ~5 times the rate of the US, they can afford to be less choosy.

    I doubt we have the data to know on your first question. Worse reactions to a vaccine could be due to all sorts of factors, some of which might be tied to better protection (but could easily be tied to things like a prior history with the vector, comorbidities in the patient, etc.). A semi technical but still readable discussion can be found here: https://www.nature.com/articles/s41541-019-0132-6 (Also look at reference 32 for a more detailed discussion of your question.)

    For your second question, it indeed appears that side effects are more pronounced among younger patients, at least based on the data reported to date.

    It’s official — delaying second dose of Covid vaccine saves lives (Paywall)

    The first real-world data from the vaccine rollout shows “promising evidence” that justifies the delayed second dose approach, a senior government vaccine adviser revealed last night.

    Professor Anthony Harnden, deputy chairman of the joint committee on vaccination and immunisation, said people who have been vaccinated are enjoying “high levels of protection from the first dose” which was reducing infections and saving lives.

    Public Health England is expected to publish the data within days. It will guide Boris Johnson and his advisers as they finalise plans to ease the national lockdown. By yesterday the number of people vaccinated exceeded 11 million.

    The data shows infection rates in the over-eighties have fallen dramatically in the past month.

    It is understandable to take the approach the UK decided on, making the caveat that it is risky because we're not really sure about the efficacy and it might be they're keeping more people in the country at risk rather than less the way they're hoping. It's also understandable to decide that such a risky approach is too likely to result in less effective coverage than the recommended two-dose strategy. But you're not willing to concede that second one. You're lambasting anyone not following your One True Path on under-tested vaccinating strategies as murdering their own citizens.

    This.

    I understand the British approach, and given the circumstances, I don't think it's a bad approach, but it does come with risks that should be acknowledged.

    Also realise that if data comes in later to support that this was the right approach, that doesn't take away the initial risk. If you win thrle lottery, that doesn't mean buying lottery tickets is sound financial advice.

    That's simply not true whatsoever. I haven't "lambasted anyone" for not following the policy that I think is a good idea, I have defended the policy as a good idea. There's a difference. If other countries don't want to take a risk I haven't condemned that - I have condemned not pre-ordering vaccines in a timely fashion, and failing to invest in their manufacturing, and failing to invest in Covax etc etc etc - but that is all agnostic to the 3 week or 12 week gap.

    I think the EU's failure to invest in manufacturing of a vaccine, and failure to sign contracts causing a three month delay on their manufacturing, and priority on negotiating price rather than procuring vaccine supply was a catastrophic failure - but that's got diddly squat to do with the 3 week gap or 12 week gap. Even if the EU switched to a 12 week gap (which I think would be a good idea, but no more than that) it wouldn't magically conjure up the millions of missing doses they've not been able to get manufactured.

    Israel is following the 3 week policy but have the doses available. I have applauded not criticised Israel's vaccine rollout.

    What I have done is defend from attack what is being done and defend it as being a good idea when it was lambasted here as not science or "consistently the dumb thing" to do, or "no evidence", despite it being from a rigorous analysis of the science available at the time. I'm awaiting a bit of acknowledgement from people here that attacked it as "the dumb thing" to do that actually it wasn't dumb afterall, but I'm not holding my breath on that level of self awareness being reached. I am also hopeful that the evidence developed in this country can help save lives overseas with more risk-averse nations being able to follow our lead.

    I don't deny there are risks, all choices during a pandemic are risky. I have never used the phrase "murdering their own citizens" nor would I.

    WTF is "age-adjusted EXTRA death" when its at home? Is that like what we would call "excess deaths"? I haven't seen Sweden's excess death figure but I'd be shocked if its as low as 3,000.

    As for your final paragraph, you're wrong. The PM, Sunak and others were speaking to all sorts of scientists, including yes some scientists with contrarian views (who are still respected scientists in their own right) and ended up going with what the SAGE scientists decided in much less than 12 weeks. Now its not been 12 weeks since the vaccine program began but there's already data and science there to be followed but you want to piss around for 12 weeks. You're more dithering than Sunak.

    I see the WHO this weekend came out and said that it was "wonderful" that the "bravery" of the UK has led to improvements in science leading to "greater protection" from the vaccine doses. Says the UK approach has been "vindicated" and "thank you British scientists".

    We can't say anything about the likelihood of the latter risk manifesting, and I don't think anyone has taken a firm position on it. RB hasn't read the posts responding to his claims properly, so he's arguing against things nobody has really said, on the basis of developments and misunderstood studies that have little bearing on the claims he thinks he's addressing.

    That's certainly one argument made by the lockdown sceptics like Toby Young, Carl Heneghan, Sunetra Gupta and more. They argue that since the case for action hasn't been made in clinical conditions with definitive results then effectively we shouldn't do anything.

    Is that the route you really want to go down? Or should we listen to the scientific experts in SAGE, the JCVI, the MHRA, the Chief Medical Officers and other scientists saying "based on the evidence before us we think the best course of action is [this] because [reasons]" even if there is no definitive way of knowing because it isn't clinically proven?

    What is known in order to reduce the risks is based upon the evidence actually available, even if it isn't "rigorously tested under clinical conditions with definitive results".

    Fascinating excess deaths chart showing the folly of comparing between countries using their 'official' Covid 19 death figures.

    Britain is one of the only nations to have recorded more Covid 19 deaths than the excess death figure. Russian stats are scary, especially noting the fact their deaths figure only goes up to November and looking where the chart stops in November. There is a part of me that wonders if Putin is OK with the virus dealing with Russia's demographics problem by letting it rip.

    Despite Cockney Covid evolving in the UK, it seems the UK hasn't actually had that many excess deaths in the second wave compared to the first. Lessons learnt after the first wave?

    Problem is, we can't be sure to minimize risks by relying exclusively on conclusive proof—it may well increase risk. What is needed is a sound strategy for structured risk-/safety-analysis, that helps policymakers and their advisors more clearly appraise policy decisions. In the case of the 12 week delay for the Pfizer vaccine, one element of such an analysis might be to demonstrate—through rigorous modeling—that we should expect a clear benefit wrt overall attack rate under a wide range of conservative or grim but plausible assumptions about the vaccine and about specific regimens, in different groups, under different circumstances wrt the behavior of the pandemic (eg. wrt transmission once the new lineages begin to dominate). In other words, we should strive to show that, even when the odds are bad, the chosen strategy looks like it'll be good. In contrast to this approach, some people have sought to show that the odds are good—using evidence that does not speak towards the specific claims being made. Putting aside philosophical concerns, what this means is that we have no idea how sensitive the policy is to mistakes on our part, eg. if we have been too optimistic about specific parameters, or if we have not foreseen dangerous developments. So, to summarize: I don't believe we can—let alone should—be fanatically reliant on conclusive proof that might not materialize before it's too late, but we can—and should—at least perform an adequate risk analysis before choosing a strategy based on limited evidence.

    "The people" = "the person", a person who hasn't engaged you much on this issue since that comment was made. As for the discussion on evidence, you haven't understood the specific points raised—by myself or by Wiggin. Hence your frustration with critical responses to your misdirected arguments.

    That is largely incorrect. The thrust of the covid denialists' arguments—both the ones you mention, and the others who have associated themselves with The Great Barrington declaration—is that we know that covid itself isn't all that bad, and that our prior belief should be that hugely disruptive and costly restrictions—eg. lockdown measures—are worse than the alternative, absent strong evidence showing a clear benefit. They portray interventions as being unnecessary, or disproportionate, or misdirected. Their reasoning is based on a number of false beliefs about the dangers of covid, the impact of the pandemic without interventions, and the evidence supporting those interventions. In no way is their reasoning comparable to anything that has been said in this thread (except, possibly, by Lewk); it is, if anything, comparable to your—and my—government's inadequate responses wrt the timeliness and thoroughness of interventions.

    The UK has relatively high excess winter mortality in general; I would expect estimates of excess covid mortality over the winter months to be mitigated by that, if they compare with the average for the same weeks in the preceding years. The measures that have been implemented also contribute to eg. lower mortality from eg. influenza and bacterial pneumonia, falls outside the home, etc. Seasonal mortality for these things varies between countries, so the impact of interventions is also likely to vary.

    This is indeed good news but I want to be really clear that this data is also extremely thin. They didn't show that there are no infections after 22 days, they showed that there were no identified infections between days 22 and 24, when there had already been very few identified infections in the previous week. Will there be infections after 22 days, when you go out to months and add more and more vaccinated people? You betcha. But it certainly looks like a 2 dose regimen for Pfizer turns a single dose infection rate (near the peak of this graph) and drops it to much lower.

    On a related note, I was reminded of a stark difference in vaccination rates today: my 33 year old sister in Israel just received her first dose of the vaccine. On the same day, my 67 year old father in the US received his first dose - and that only because he works in a school; my 67 year old mother will likely receive her first dose in a few weeks if she's lucky. I, meanwhile, am technically considered an essential worker (for reasons that are rather unclear to me), and may receive my first dose in another month or so. But my wife - broadly similar age and risk status to my sister - probably won't get her first dose until April or May.

    A vaccine doesn't have to be 100% effective to be worthwhile, don't let the hunt for perfection be the enemy of the good enough for now. Absolutely there may be some more confirmed infections afterwards but even disregarding the "no infections" claim the distinction between 12,944 people infections in the unvaccinated group (166 per 10k) and 254 infections in the vaccinated group (6 per 10k) is absolutely remarkable. 166 per 10k to 6 per 10k even if the other group isn't a perfect control group is an amazing distinction.

    As for the two doses being better than a single dose that certainly looks true but this is yet more evidence in my eyes to a single dose for as many people then the second dose strategy. The baseline at day 7 is 76 infections - even if you multiply that by 18 days (7 to 24) then that would be 1,368 infections or 32.8 infections per 10,000; which assuming they've made a like-for-like date range comparison would be an 80% reduction from the original dose alone. If the original dose gives 80% protection and the booster bumps that up to circa 99% potentially then its well worth doing the booster, but its even more worth (if limited supplies exist) getting it to as many people first.

    Finally of course there's the herd immunity factor. As Israel, the UK and other nations approach getting everyone vaccinated then even if the vaccine protection is imperfect on an individual basis there should be fewer viral spread and thus fewer opportunities for the imperfect protection to fail.

The baseline at day 7 is 76 infections - even if you multiply that by 18 days (7 to 24) then that would be 1,368 infections or 32.8 infections per 10,000; which assuming they've made a like-for-like date range comparison would be an 80% reduction from the original dose alone. If the original dose gives 80% protection and the booster bumps that up to circa 99% potentially then its well worth doing the booster, but its even more worth (if limited supplies exist) getting it to as many people first.

    Finally of course there's the herd immunity factor. As Israel, the UK and other nations approach getting everyone vaccinated then even if the vaccine protection is imperfect on an individual basis there should be fewer viral spread and thus fewer opportunities for the imperfect protection to fail.
    I am not disputing that 1 dose looks good and 2 doses look great (though I would hesitate to put numbers on them given such a small number of events, especially for 2 doses). I'm just disputing the headline of 'no infections after day 22', which really means 'we were only seeing a few infections a day before day 22 and now we saw three consecutive days with no infections'. It's not Tim's fault, this is what the Reuters graphic specifically says. But it's important to contextualize data to understand what it actually means - which, in this case, is not very much.

    The broader story is quite encouraging, yes. We have about 6 weeks of data on a large scale rollout of the Pfizer vaccine and when used as authorized it certainly appears to be dramatically reducing infections. I look forward to longer term surveillance on ever larger cohorts, but the body of evidence supporting the as-tested use of the Pfizer vaccine is growing. I expect to see similar data come out from Israel with the Moderna vaccine in the coming months.

    In my naivety, I'd assumed the construction of the massive Northvolt factory outside a nearby town had been put on hold. Turns out that was not the case—and it's now the epicenter of what will probably develop into a pretty bad outbreak, with the UK lineage accounting for a large share of cases. My county has been very good at managing the epidemic so far, by Swedish standards, but there's little a county can do to stop a company from gathering over a thousand construction workers from other parts of the country—and the continent—at a single site, crowd them together in barracks, and make them move around freely in the community with little to no restrictions. My hospital has been offloading several other hospitals in the region, but we're going to have our hands full with our own outbreak before long, thanks to ongoing contact with the town that has been hit by the aforementioned outbreak (and, of course, with other hotspots). The county govt. & hospital management hadn't realized that a lot of people who work in the ER don't actually belong to that department, so their vaccine rollout plan has overlooked many of us who're liable to meet covid patients under unsecure circumstances. They're reserving beds for covid patients at one—maybe two—of our wards, but have neglected to vaccinate the nurses, nursing assistants and half of the doctors who'll be working there. Most of our day-to-day activity involves acute care that can't be put on hold, so the inevitable attrition among staff that will result from exposure and sickness will be very difficult to manage. Technically, I'm supposed to have three months off for a time-sensitive research project, but they've already cannibalized a month of that time, and I'm counting on more being lost due to last-minute orders. It is what it is, but... this was very much avoidable.

    Given my new diagnosis I could be up for vaccination in March.
    Congratulations America
