Omicron variant, wat wetenschap ervan weet 30nov2021 The Omicron variant: What we know so far Betoog: 1) Deze omicron variant is nieuw, men ziet mildere klachten, maar in zuid afrika is maar 6 procent bejaard dus daar werkt het anders, dan in Nederland waar minstens 20 procent al oud is, 60plussers en veel meer chronisch zieken. 2) Omicron kan mogelijk een slachting aanrichten in landen met veel minder validen, chronisch zieken en bejaarden. Reeds gevaccineerden gaan nu ook gewoon dood door de nieuwe Delta variant en omicron komt nu een handje mee helpen, is binnen 2 maanden in heel europa zeker verspreid, via de koude wind. 3) Ja zelf denk ik dat Dharti Maata gelijk heeft om met harde hand, doch liefdevol en barmhartig nu even nog paar miljoen mensen op te ruimen op aarde, er komen per jaar ruim 80 miljoen mensen bij op aarde in totaal dus covid19 haalt dit aantal beslist niet denk ik, en de menselijke wereldbevolking zal dus toch door blijven groeien tot tien miljard in 2040 op dit tempo. MOeder Natuur zal zeer zeker zwaarder genocidaal geschut in stelling brengen denk ik nu. 4) Gouden tijden, genieten voor mensenhaters, KLimaat fascisten, Groene Nazies, 5) pluspuntje: massale sterfte van chronisch zieken en bejaarden zal de zorgkosten verlagen, pensioen lasten worden lager en pensioen fondsen winnen erbij. Ook ontstaat er overdracht van opgepot dood liggend vermogen, dus vers consumptie kapitaal komt vrij na de dood van al die bejaarden, erfenis bedrag door corona sterfte en oversterfte erbij moet nu al in de orde zijn van 5 tot 30 miljard euro in hele EU of zelfs meer, onroerend goed komt erbij. Letterlijk: de een z'n dood is de ander z'n brood. ----------------------------- harde science he https://www.livescience.com/omicron-...2-8a7daf4af060 The Omicron variant: What we know so far By Yasemin Saplakoglu 1 day ago From its origin to its likely impact, here's everything we know so far about Omicron. On Nov. 26, the World Health Organization (WHO) named a new coronavirus variant "Omicron" and designated it as a "variant of concern." But what makes this SARS-CoV-2 variant different and why are scientists worried about it? Because the variant has only been recently identified, there's a lot we don't know about it. Scientists are concerned that Omicron has a very high number of mutations, many of them in genes that code for the spike protein, which the coronavirus uses to latch onto and invade human cells. Early evidence suggests that people who previously recovered from COVID-19 may have a higher risk of reinfection with Omicron compared with prior variants, according to a statement from the WHO. But it's not yet clear how severe or transmissible Omicron is, nor is it clear how current COVID-19 vaccines will fare against it. Experts say it's likely that the vaccines will be less effective due to these mutations, but they will likely still confer some protection. From its origin to its likely impact, here's everything we know so far about Omicron. Origin Officials in South Africa first reported Omicron (B.1.1.529) to the WHO on Nov. 24, following a sharp increase in cases in Gauteng province in the previous weeks. The first known and confirmed infection with Omicron was from a sample taken on Nov. 9, and now, the number of Omicron cases is rising across South Africa, according to a WHO statement. Though South Africa was the first to report Omicron to the WHO, it's not clear what country the variant emerged from, according to NPR. Many countries have since put travel bans on many southern African countries including South Africa. "There is very little utility of these kinds of bans," Saad Omer, director of the Yale Institute of Global Health, told NPR. Omicron has also been detected in Canada, Austria, Belgium, Denmark, England, France, Germany, Italy, The Netherlands, Portugal, Scotland, Botswana, Israel, Australia and Hong Kong, according to The Washington Post. Common PCR tests can detect the Omicron variant and easily distinguish it from other variants due to a mutation in one of the three genes that the test targets. "Using this approach, this variant has been detected at faster rates than previous surges in infection," according to the WHO. Mutations Omicron has more than 30 mutations in the genes that code for the spike protein, according to Nature. Of these mutations, 10 are in the "receptor binding domain," or the part of the spike protein that latches onto human cells, according to The Guardian. Meanwhile, other mutations, some of which were previously found in past variants, are "concerning" and could be linked to higher transmissibility or could help the virus evade immune defenses, according to a technical brief released by the WHO on Nov. 28. "The likelihood of potential further spread of Omicron at the global level is high," according to the brief. Severity It's not yet known whether Omicron causes more severe disease compared with previous variants. Early evidence suggests hospitalization rates are increasing in South Africa, "but this may be due to increasing overall numbers of people becoming infected, rather than a result of specific infection with Omicron," according to the WHO. Only about 24% of South Africa's population is fully vaccinated against COVID-19, according to Our World in Data. The first reported infections in South Africa were in university students, who are "younger individuals who tend to have more mild disease." However, only about 6% of the population of South Africa is older than the age of 65, according to the Telegraph. So it's unclear whether the variant will cause more severe disease in those who are at increased risk, such as older people. No solid evidence suggests that symptoms of Omicron differ from those of previous variants, according to the WHO. But Dr. Angelique Coetzee, a private practitioner and chair of South African Medical Association, told the BBC that the patients she's seen so far with the new variant have had "extremely" mild symptoms. Of the few dozen patients she's seen recently who tested positive for COVID-19, most were healthy young men who turned up "feeling so tired," Coetzee told the Telegraph. None of her patients had loss of taste or smell, and none needed to be hospitalized, according to the BBC. However, these early anecdotal reports can be misleading and it's still too early to say whether Omicron causes milder or more severe disease than earlier variants. Transmissibility It's not yet clear if Omicron spreads more easily from person to person compared with previous variants. The number of people in South Africa who have been testing positive for COVID-19 has increased in areas battling Omicron, but it's not yet clear if the rise can be explained by the spread of the new variant or other factors, according to the WHO. Vaccine effectiveness It's also not known how effective current COVID-19 vaccines will be against Omicron. Most COVID-19 vaccines, including those used in the U.S., prime the immune system specifically against the spike protein. Because Omicron has many mutations in the spike protein, experts are worried that current vaccines may be less effective at training the immune system to recognize it. "Based on lots of work people have done on other variants and other mutations, we can be pretty confident these mutations are going to cause an appreciable drop in antibody neutralization," or the ability of antibodies to attach to the viruses and stop them from invading human cells, Jesse Bloom, an evolutionary biologist at the Fred Hutchinson Cancer Research Center in Seattle, told the New York Times. But experts told The Guardian that while vaccines may be somewhat less effective against Omicron compared with previous variants, they will probably still confer some protection. "I think a blunting rather than a complete loss [of immunity] is the most likely outcome," Paul Morgan, an immunologist at Cardiff University told the Guardian."While some of the antibodies and T cell clones made against earlier versions of the virus, or against the vaccines may not be effective, there will be others, which will remain effective." What's more, T cells, or immune cells that attack virus-infected cells, may be more "impervious" to differences among variants compared with antibodies, Danny Altmann, professor of immunology at Imperial College London told The Guardian. RELATED CONTENT —11 (sometimes) deadly diseases that hopped across species —14 coronavirus myths busted by science —The deadliest viruses in history Researchers around the world — including those at Pfizer-BioNTech and Moderna, the developers of the two mRNA COVID-19 vaccines widely used in the U.S. — are working to understand how effective vaccines are against the variant, according to The Times. "If we have to make a brand new vaccine, I think that's going to be early 2022 before that's really going to be available in large quantities," Paul Burton, Moderna's Chief Medical Officer said on BBC's Andrew Marr Show on Sunday (Nov. 28). Moderna and Pfizer-BioNTech's COVID-19 vaccines are based on mRNA technology, which is quicker to develop and edit compared to previous vaccines, Live Science previously reported. "The remarkable thing about the mRNA vaccines, the Moderna platform, is that we can move very fast," Burton said. Originally published on Live Science.

![]() zo doet china het overal nu en het werkt perfekt
india doet het ook geloof ik die korte, kleingeschapen zwartjes zijn toch slimmer he hahha haha dan de lange, blanke Ubermenschen van superieur Europa hahha -------------- science facts zo simpel kan het ook ok, GEEN lockdown nodig dan https://www.businessinsider.nl/bipol...onal=true&r=US Used in large-scale ventilation systems worldwide, bipolar ionization could be a secret weapon in the war against COVID-19 Business Insider US 08 apr 2020 Bipolar ionization technology releases charged atoms that attach to and deactivate harmful substances like bacteria, mold, allergens, and viruses. It first arrived in the US in the 1970s as a tool to control pathogens in food manufacturing. Bipolar ionization has already proven effective against SARS, norovirus, and several influenza strains. Visit Business Insider’s homepage for more stories. Bipolar ionization is experiencing a surge in popularity as the coronavirus pandemic fans concerns about air quality. Integrated into HVAC systems, the technology utilizes specialized tubes that take oxygen molecules from the air and convert them into charged atoms that then cluster around microparticles, surrounding and deactivating harmful substances like airborne mold, bacteria, allergens, and viruses. They also attach to expelled breath droplets and dust particles that can transport viruses, enlarging them so they’re more easily caught in filters. It’s an active process that provides continuous disinfection. ADVERTENTIE Lees meer “The ions produce a chemical reaction on the cell membrane surface that inactivates the virus,” Philip Tierno, a clinical professor of microbiology and pathology at the NYU School of Medicine, told Business Insider. “It can reduce 99.9% of microbes in a matter of minutes.” The battle against the coronavirus could be an air fight Concerns about airborne transmission have grown as new research indicates the novel coronavirus can remain airborne longer and spread further than previously thought. Some experts now believe that just normal breathing can spread the virus. “The possibility of aerosolized spread of COVID-19 and the ability of particles to hang in the air for extended periods of time would make the consideration of an active air-cleaning strategy even more prudent,” Tierno said. Long popular in Europe, bipolar ionization first arrived in the US in the 1970s as a tool to control pathogens in food manufacturing. It was effective during the SARS outbreak of 2004, as well as more recent outbreaks of MERS and norovirus and various strains of influenza. Recent advances have made units cheaper and easier to install and companies are scrambling to test the technology against the coronavirus. According to Tierno, early results have been positive: “Because coronaviruses are enveloped viruses, they are easier to kill compared to naked viruses like noroviruses.” Many large venues already employ bipolar ionization Hospitals including Johns Hopkins, Children’s Hospital Boston and the University of Maryland Medical Center have already embraced the technology. “Bipolar ionization has been used in healthcare for many years for many applications,” Tony Abate, chief technical officer at AtmosAir Solutions, told Business Insider. “We believe bipolar ion systems will become a standard in these critical environments to protect patients and staff. https://www.businessinsider.nl/bipol...onal=true&r=US ----------------------- |

![]() Wat ik niet goed begrijp is dat het vaccin zogezegd betere immuniteit zou leveren dan natuurlijke infectie met de variant-van-de-dag. De MRNA vaccins bootsen kunstmatige virusjes na: Vetdruppeltjes met MRNA in, die MRNA wordt in de cel gebracht, en de cel gaat aan het produceren van wat in die code staat. Nu is die code al erg oud: Origineel door de Chinezen (!) meegedeeld aan de grote pharma bedrijven, die daarmee aan de slag gingen en welke nu in 94% van de volwassenen hun arm zit in België. Hoe die Chinezen zo snel aan die code kwamen en er vanuit de pharma weinig vragen over juistheid waren is een ander verhaal (Mijn theorie: ze hadden dit al liggen want ze hadden het virus zelf gesequenced in Wuhan)
Nu, het eiwit dat hierin zit is het spike eiwit van het virus, één van de 29 eiwitten die het virus opmaken. Hiervan zijn er maar 4 structurele eiwitten (maw. die het virus letterlijk vorm geven), en 25 andere eiwitten die dienen om het immuunsysteem om de tuin te leiden. Het vaccin laat je lichaam echt massieve hoeveelheden van dit spike proteine produceren, grootteordes meer dan je bij de gemiddelde infectie zou meemaken. Die proteines presenteren zich op de celwand, maar gaan ook vrij rondcirculeren in de bloedbaan en lymphebanen. Je immuunsysteem gaat al die "gekke" cellen opruimen, al die proteines verwijderen, en door de massieve aanval hiervan hierop ook een sterke immuniteitsreactie opbouwen. Zo een massieve spike-aanval mag dus nooit nog voorkomen! Bij een natuurlijke infectie ga je het hele ding natuurlijk in je lijf krijgen, alle 29 eiwitten in al hun glorie. De spike is er een grote van, maar ook op alle andere structurele en immuun-ontwijkende eiwitten kan je systeem gaan trainen. Gezien dit steeds een vorm van "gooi alles ernaar en zie wat blijft plakken" is, is de uiteindelijke vorm van immuniteit slecht te voorspellen. De ene zal inderdaad erg op de spikes inzetten, maar bij anderen kunnen andere subtielere componenten van het virus de immuniteit triggeren. In de praktijk is het ook een soepje van verschillende reacties op verschillende delen van het virus. Nu komt er een Omikron variant langs, met massieve mutaties in het spike proteine. Zo massief dat zelfs de PCR testen het niet meer oppikken (zo differentieert men Omikron van de oudere stammen). Mijn verstand kan er dan niet bij dat zogezegd het immuunsysteem dat enkel getrained is op de oude spike beter is dan het immuunsysteem dat op veel meer en modernere eiwitten getrained is. De kans dat bij de laatste er wel ergens een component in gang zal schieten lijkt me veel groter. Dit kan natuurlijk de zenuwachtigheid hierrond verklaren, en alle "we weten het nog niet, het is te vroeg, we hebben meer tijd nodig" reacties. Men weet misschien goed genoeg wat men aan dit beestje heeft, en waartoe dit zal leiden: Terug naar af, behalve voor degenen met natuurlijke immuniteit. Nu raprap iedereen verplicht injecteren kan een oplossing bieden natuurlijk. Niet voor het medische probleem maar voor het politieke: Zo wordt het erg moeilijk tot onmogelijk het falen van de vaccins in een juist kader te plaatsen door het ontbreken van een groot genoeg "placebo" publiek. |

![]() 2 kinderen zijn twee weken geleden nog in China (Beijing) geweest. Ze hebben daar aan den lijve de Chinese aanpak kunnen ondervinden - verboden het hotel uit te komen, tenzij in de speciale bus die de overheid voor hen voorzien had, dagelijks testen, overal begeleid door bewakers in full hazmat (die bovendien verplicht 2 weken in quarantaine moesten nadien), verboden samen te eten, noem maar op. Maar van ionisatie apparaatjes was geen sprake.
