joerg>><Rudd-O[m]> Right now the important thing is to do what the authorities tell us to do.« could you please STFU04:58
joerggustik: that vax mandate discussion is quite unfortunate. In RL any such mandatory vaccination would only be enforceable by controls e.g. in trains when checking tickets, in pubs on entrance etc anyway, and if you do that you basically don't need a vax mandate since a 2G or somesuch has basically exactly same effect05:10
joergand no, you can't get absolution from a mandatory vaccination by paying a fine, however high05:11
joergso yeah, what you gonna do with those who refuse?05:11
joergin final consequence you need to lock them away. I guess we won't be willing to do that05:13
joergpoliticians were idiots however to rule out any mandatory vaccination or any other possible measure from beginning. It is an immanent property of such an emergency that you don't know what you gonna face and what you gonna need to cope with the stuff you will face05:15

joerganyway mandatory vaccination right now is a thing the people (some 50% in germany right now) ask for, but that's again complete nonsense. Not a topic to even discuss right now, since any vaccination *now* isn't the solution to cope with 4th wave any more. Even if we started tomorrow vaccinating people as fast as we been able to in best times in last spring and summer, we would see effects no earlier than February next year05:51

aradeshi've heard about this new "symptomless strain" of covid being investigated09:19
aradeshthat could be good in theory right? it would give people a natural immunity to a similar strain to the deadly ones09:19
joergnever heard of it before. your conclusions sound plausible09:19
aradeshAY.4.2 strain09:20
joergta! http://reisenweber.net/irclogs/libera/__covid-19/search?q=AY.4.2%28%3Fi%2909:21
aradeshmaybe it's not really symptomless09:21
aradeshbut some news articles are reporting it as such09:21
aradeshif you google "symptomless strain" you'll find lots of articles saying that09:23
aradeshthough there's no way you could force a symptomless strain to spread around everyone, without also making them also vulnerable to catching the other strains09:26
aradeshbut09:26
aradeshgiven how bad we are at preventing spread09:26
aradeshif this one spreads around and has less severe symptoms, in general that can't be too bad if it gives some natural immunity09:26
joergaround http://reisenweber.net/irclogs/libera/__covid-19/__covid-19.2021-10-29.log.html#t2021-10-29T17:04:32 doesn't sound to me like anything would suggest AY.4.2 was "symptomless"09:29
aradeshyeah09:32
joergthen, nothing says it is _not_09:32
aradeshbut then why are all these news articles describing it as such09:32

aradeshand so on09:32
aradeshall from the last few days09:32
joerga good question. They got to have an original source for that info, would be interesting to spot and read that09:33
aradeshyes09:33
aradeshmy covid-sceptic friends are all over it09:33
joergsounds almost like that idea that came up half-tongue-in-cheeck in here a year or so ago came true: make a vaccination-virus and spread it09:35
joerg;-)09:35
aradeshi became alerted about this story from this from covid-skeptic types: https://i.imgur.com/bYeDC29.png09:36
aradeshthey always get so excited with badly worded news stories09:36
aradeshlol09:36
aradeshthat's what they thrive off. politicians/spokes people/news articles that word things badly09:37
aradeshand then use that as evidence that it's all a lie09:37
joergsidenote anecdote: diagnosis of the progressive paralysis that killed my dad  » some virus you caught 10 or 20 years ago and that had no symptoms other than now destroying your nerves «09:39
joergI can't recall the name of the virus since I was a youngster still and went "meh, this doen't help me either"09:40
aradeshis that an anecdote that symptomless viruses might still be a concern?09:41
joergsort of09:41
joergat last that a symptomless infection still is an infection by a disease that exists09:42
joergthose folks you referred to are ignorant and not capable to think beyond a mere black-or-white approach09:44
aradeshthe covid skeptic types don't seem to appreciate that governments do lockdowns due to hospital overload not just imagining a problem due to graphs09:44
aradeshwell, they don't believe it09:44
aradesheven if you point it out09:44
aradeshsay it's all made up, etc09:44
aradesh"largely shown to be a myth" they say09:45
aradeshor if not hospitals being overloaded, their friends in a country next door having that problem so they don't want it to happen to them09:45
aradeshbut in the UK it's always been "wait until the hospitlas are full, then maybe do something"09:46
joergwell, same here in germany but the idiots still ignore/deny there's a problem even if you show them pictures of an ICU station in their town or pull them by the hair and drag them across that station09:53
joergmaybe separate new "hospitals" exclusively for unvaccinated covid-cases would "help"09:55
joergif those are filled, too bad. Can't treat you, sorry. While regular hospitals still could work as usual, without the load from those who actually don't want to get a treatment09:56
joergaradesh: you're aware that those two links you gave are basically same company, and not exactly a source of news I'd consider particularly trustworthy, to put it politely10:04
joergI don't know ${town}live.co.uk but the identical text and the whole appearance of both sites make me feel like I'm not really interested in finding out how trustworthy that (group of) news site is10:18

joergusually triage, though some doctors claim that this term isn't applicable since it would refer to "actively terminating life of one patient in favor for another". I frown a bit on "actively", no idea what they think this means11:15
joerg>>In medicine, triage (/ˈtriːɑːʒ, triˈɑːʒ/) is a practice invoked when acute care cannot be provided for lack of resources. The process rations care towards those who are most in need of immediate care, and who benefit most from it.

aradeshany idea what the half life is for natural immunity?17:14
de-factonote that breakthrough does not mean a progression as severe as non vaccinated, it begins with mild cases and increases in severity the longer the timespan between last vaccination and breakthrough occurring17:14

de-factoyet afaik the data points spread over a much larger range for immunity from recovery17:16
lastshellthank you guys17:17
de-factolastshell boosting will not only raise your antibody levels, it probably also will motivate your immune system to make a broader variety of antibodies hence potentially also may cover better future variants (that has to be seen though)17:17
de-factothat is because to the immune system boosting looks like a breakthrough infection: lots of antigen (s-protein) visible again hence it was an evolutionary advantage to react with a broader variety of antibodies to prevent that breakthrough (simulated by vaccination booster)17:19

Dredd<joerg> ">><ruddo> Right now the importan..." <- Could you please try to disagree with people now amicably in future?17:35
ArsaneritI thought herd immunity was impossible with delta and current vaccines, but this article seems to suggest otherwise?  https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(21)00495-1/fulltext17:38
de-factowell vaccinations do lower the risk of infection and also lower the duration of spread etc, so in addition to the other measures they do contribute to lower the reproduction number Rt17:41
ArsaneritLower, yes, but doesn't herd immunity require that vaccines alowe reduce Rt to less than one?17:43
de-factothe term "herd immunity" refers to achieving endemic (R0 = 1) state by removing a sufficient part of potential carriers from the infection chains in a fully naive (non-immunized) and non-aware (no additional containment measures) population17:43
de-factonote the difference between Rt and R017:43
de-factoboth Portugal and Spain do have low number of infections but they increase there too17:49
de-factohttp://offloop.net/covid19/?default=Portugal;Spain&byPopulation=yes&cumulative=no&smooth=yes&miscType=Reff&leftTrim=650&legacy=no17:49
de-factonote their Rt(4d) ~ 1.25 in the last weeks meaning doubling in T2 = 4d Ln(2) / Ln(1.25) ~ 13d17:50
DreddI'll pretend I know what that means 😂17:51
de-factoit means their daily number of those that test positive for an infection doubles each 2 weeks17:52
ArsaneritR₀ is the reproduction number if nobody is immune and there are no interventions?17:52
de-factoyes17:53
ArsaneritThen why does the Lancet article speak of herd immunity?17:54
de-factoR0 describes the theoretical maximum of viral spread, hence the "worst case" scenario where every carrier infects the maximum number of suceptible17:54
darsieLike coughing at ppl rather than in their elbow?17:54
de-factoyeah for example17:55
ArsaneritBut you wrote herd immunity achieves R₀ = 1 ?17:55
de-factoin a fully susceptible (immuno-naive) and unaware (no additional containment) we require steady state (no increase/decrease of cases) with R0 (1 - v) = 1 hence removing v = (R0 - 1) / R0 infections from each generation by e.g. vaccination18:01
ArsaneritI thought R0 was the theoretical number assuming no vaccinations?18:01
de-factoexample: suppose we have a pathogen with R0 = 5, so every carrier infects approximately 5 susceptible in each generation leading to 5^generationtime infections emerging from each carrier18:02
de-factonow removing v = (5-1)/5 hence 4 out of each 5 potential infections leads to each carrier only infecting 1 susceptible, hence endemic state with Rt = R0 (1 - v) ~ 1 where daily new infections neither increase nor decline18:04

de-factoremoving refers to all combined measures that reduce reproduction = contact_rate * transmissibility * spread_duration, hence if no additional measure is the goal it would have to be achieved by vaccinations alone18:06
Arsaneritde-facto: yes, I understand that it's endemic when Rt = ~ 1, but was confused by your statement at 17:43 CET where you wrote R0 = 118:07
de-factonow the question is: are current generation of vaccines (alone) able to achieve such a reduction for a reproduction number as high as the one for Delta VoC?18:07
de-factoArsanerit i wanted to put emphasis on no additional measures except removing from a sufficient part from fully susceptible and unaware population by one chosen measure (e.g. vaccination)18:12
de-factohence the example calculation (with arbitrary numbers)18:13
Arsaneritde-facto: oh, I see18:14
de-factowe could even put in vaccine efficacy in such a "back of the envelope" quick estimate (its far from being accurate though since it assumes equality of all carriers and ignores over-dispersion for high contact rate or high spread scenarios)18:14
Arsaneritde-facto: I had understood the answer to that question was "no, it isn't", which is why I was surprised by the headline in The Lancet18:14
de-factothat would be Rt = R0 ( 1 - VE * V ) for vaccine efficacy VE (against transmission!) requiring to remove a portion of V = (R0 - Rt) / (R0 * VE) from infection chains in a fully susceptible unaware population18:17
de-factonote the symmetry in the product for VE and V, hence we would need a vaccine efficacy VE = (R0 - Rt) / (R0 * V) to achieve Rt when a portion of V is vaccinated18:18
de-factoalso note all of those are functions of time, e.g. Rt[ŧ] = R0[t] * ( 1 - VE[t] * V[t] ), R0[t] representing increase in pathogen fitness (e.g. new VoCs), VE[t] representing waning of (transmission!) immunity by vaccinaiton and V[ŧ] representing vaccination progress for a given associated VE[t]18:25
ArsaneritI wish there was a delta-specific vaccine for the booster18:31
de-factobtw i wrote VE against transmission because its different from the VE reported in the studies (e.g. the veterans study above) that uses other endpoints ( I guess symptomatic infection )18:31
ArsaneritI thought mRNA-vaccines were easy to adapt to variantse, if they are, then why are approved vaccines still for the wuhan strain only?18:31
de-factosurely not due to a (bio)technical problem18:32
de-factoiirc Ugur Sahin (CEO of BioNTech) stated it would take ~6w to implement a new s-protein signature in the mRNA vaccines18:33
LjLand it probably does, but that's an insignificant amount of time compared to the time to produce enough of them and to test for safety18:34
LjLas i said i think the regulatory process could benefit from being streamlined, BUT, we still do need reasonably robust testing18:34
LjL"no ADE" now doesn't automatically mean no ADE always18:35
LjLand proteins can interact in unexpected ways, even if it's "just similar" to the protein we were already using (so is the virus's, right? but it means a big difference!)18:35
LjLso it's not like we can just take 6 weeks, or even remotely close, to bring a new signature to the market18:35
LjLthat said, yes, gee, hurry up with it18:35
de-factowell actually the regulary processes are streamlined as much as possible while still ensuring they have enough data for safety estimates18:38
Arsaneritit's sufficiently streamlined for some people to use it as a stated reason to distrust vaccine safety...18:39
de-factoyet the antigenic drift with the pathogen also progresses, so e.g. exposure to Delta s-protein probably will happen sooner or later, honestly id prefer the controlled way via vaccination rather than the uncontrolled way by contamination with wild type18:39
de-factoi wish they would streamline it more and do more parallel testing18:41
de-factowhy dont we have mandatory trials for all vaccine manufacturers that want to have contracts with EU for every declared SARS-CoV-2 VoC and VoI?18:42
de-factoe.g. if they want to keep their approval they would need to agree to constantly run trials for all known VoCs and VoIs?18:42
de-factothey could choose not to do so, but then also loose their expensive approval and a very lucrative market18:43
ArsaneritWould those trials have to find people who so far weren't vaccinated at all, or could they have "booster trials" or so?18:44
de-factothe trials would have to be accurate for the majority of target groups, hence in the case of EU id assume for those that already completed primary vaccination series18:46
de-factoso it would be a potential "early advantage" to participate in such trials18:46

aradeshi bet they're working on some new vaccines anyway (don't know but would imagine so ...)18:55
de-factobtw there also are methods to increase that, e.g. in a double blinded trial the verum group (with lower expected breakthrough attack rate) may be N-fold bigger than the associated placebo group (with higher expected infection attack rate)18:58
de-factoafaik they do study designs like 2:1 for verum:placebo cohort size18:59
de-factoyes i really do hope they are working on new vaccine generations, e.g. i desperately look forward to see stats on intranasal vaccination trials19:00
Arsaneritany idea on a timeline when we might see the first vaccines approved for delta?  Some time in 2022?19:00
de-factoespecially i am curious about intranasal vaccine efficacy against transmission and the time evolution of that (e.g. half life and absolute protection etc)19:01
