On nonconformism, or why we need to be seen and not herded | Aeon Essays - 0 views

  • When we are herding, neuroimaging experiments show increased activation in the amygdala area of the brain, where fear and other negative emotions are processed. While you may feel vulnerable and exposed on your own, being part of the herd gives you a distinct sense of protection. You know in your guts that, in the midst of others, the risk of being hit by a car is lower because it is somehow distributed among the group’s members
  • The more of them, the lower the risk. There is safety in numbers. And so much more than mere safety.
  • Herding also comes with an intoxicating sense of power: as members of a crowd, we feel much stronger and braver than we are in fact.

  • The same person who, on his own, wouldn’t ‘hurt a fly’ will not hesitate to set a government building on fire or rob a liquor store when part of an angry mass. The most mild-mannered of us can make the meanest comments as part of an online mob.
  • Once caught up in the maelstrom, it is extremely difficult to hold back: you see it as your duty to participate. Any act of lynching, ancient or modern, literal or on social media, displays this feature. ‘A murder shared with many others, which is not only safe and permitted, but indeed recommended, is irresistible to the great majority of men,’ writes Elias Canetti in Crowds and Power (1960).
  • The herd can also give its members a disproportionate sense of personal worth. No matter how empty or miserable their individual existence may otherwise be, belonging to a certain group makes them feel accepted and recognised – even respected. There is no hole in one’s personal life, no matter how big, that one’s intense devotion to one’s tribe cannot fill, no trauma that it does not seem to heal.
  • to a disoriented soul, they can offer a sense of fulfilment and recognition that neither family nor friends nor profession can supply. A crowd can be therapeutic in the same way in which a highly toxic substance can have curative powers.
  • Herding, then, engenders a paradoxical form of identity: you are somebody not despite the fact that you’ve melted into the crowd, but because of it
  • You will not be able to find yourself in the crowd, but that’s the least of your worries: you are now part of something that feels so much grander and nobler than your poor self
  • Your connection with the life of the herd not only fills an inner vacuum but adds a sense of purpose to your disoriented existence.
  • The primatologist Frans de Waal, who has studied the social and political behaviour of apes for decades, concludes in his book Mama’s Last Hug (2018) that primates are ‘made to be social’ – and ‘the same applies to us.’ Living in groups is ‘our main survival strategy’
  • we are all wired for herding. We herd all the time: when we make war as when we make peace, when we celebrate and when we mourn, we herd at work and on vacation. The herd is not out there somewhere, but we carry it within us. The herd is deeply seated in our mind.
  • As far as the practical conduct of our lives and our survival in the world are concerned, this is not a bad arrangement. Thanks to the herd in our minds, we find it easier to connect with others, to communicate and collaborate with them, and in general to live at ease with one another. Because of our herding behaviour, then, we stand a better chance to survive as members of a group than on our own
  • The trouble starts when we decide to use our mind against our biology. As when we employ our thinking not pragmatically, to make our existence in the world easier and more comfortable in some respect or another, but contemplatively, to see our situation in its naked condition, from the outside.
  • In such a situation, if we are to make any progress, we need to pull the herd out of our mind and set it firmly aside, exceedingly difficult as the task may be. This kind of radical thinking can be done only in the absence of the herd’s influence in its many forms: societal pressure, political partisanship, ideological bias, religious indoctrination, media-induced fads and fashions, intellectual mimetism, or any other -isms, for that matter.
  • a society’s established knowledge is the glue that keeps it together. Indeed, this unique concoction – a combination of pious lies and convenient half-truths, useful prejudices and self-flattering banalities – is what gives that society its specific cultural physiognomy and, ultimately, its sense of identity
  • By celebrating its established knowledge, that community celebrates itself. Which, for the sociologist Émile Durkheim, is the very definition of religion.

Reasons for COVID-19 Optimism on T-Cells and Herd Immunity - 0 views

  • It may well be the case that some amount of community protection kicks in below 60 percent exposure, and possibly quite a bit below that threshold, and that those who exhibit a cross-reactive T-cell immune response, while still susceptible to infection, may also have some meaningful amount of protection against severe disease.
  • early returns suggest that while the maximalist interpretation of each hypothesis is not very credible — herd immunity has probably not been reached in many places, and cross-reactive T-cell response almost certainly does not functionally immunize those who have it — more modest interpretations appear quite plausible.
  • Friston suggested that the truly susceptible portion of the population was certainly not 100 percent, as most modelers and conventional wisdom had it, but a much smaller share — surely below 50 percent, he said, and likely closer to about 20 percent. The analysis was ongoing, he said, but, “I suspect, once this has been done, it will look like the effective non-susceptible portion of the population will be about 80 percent. I think that’s what’s going to happen.”

  • one of the leading modelers, Gabriela Gomes, suggested the entire area of research was being effectively blackballed out of fear it might encourage a relaxation of pandemic vigilance. “This is the very sad reason for the absence of more optimistic projections on the development of this pandemic in the scientific literature,” she wrote on Twitter. “Our analysis suggests that herd-immunity thresholds are being achieved despite strict social-distancing measures.”
  • Gomes suggested, herd immunity could happen with as little as one quarter of the population of a community exposed — or perhaps just 20 percent. “We just keep running the models, and it keeps coming back at less than 20 percent,” she told Hamblin. “It’s very striking.” Such findings, if they held up, would be very instructive, as Hamblin writes: “It would mean, for instance, that at 25 percent antibody prevalence, New York City could continue its careful reopening without fear of another major surge in cases.”
  • But for those hoping that 25 percent represents a true ceiling for pandemic spread in a given community, well, it almost certainly does not, considering that recent serological surveys have shown that perhaps 93 percent of the population of Iquitos, Peru, has contracted the disease; as have more than half of those living in Indian slums; and as many as 68 percent in particular neighborhoods of New York City
  • overshoot of that scale would seem unlikely if the “true” threshold were as low as 20 or 25 percent.
  • But, of course, that threshold may not be the same in all places, across all populations, and is surely affected, to some degree, by the social behavior taken to protect against the spread of the disease.
  • we probably err when we conceive of group immunity in simplistically binary terms. While herd immunity is a technical term referring to a particular threshold at which point the disease can no longer spread, some amount of community protection against that spread begins almost as soon as the first people are exposed, with each case reducing the number of unexposed and vulnerable potential cases in the community by one
  • you would not expect a disease to spread in a purely exponential way until the point of herd immunity, at which time the spread would suddenly stop. Instead, you would expect that growth to slow as more people in the community were exposed to the disease, with most of them emerging relatively quickly with some immune response. Add to that the effects of even modest, commonplace protections — intuitive social distancing, some amount of mask-wearing — and you could expect to get an infection curve that tapers off well shy of 60 percent exposure.
  • Looking at the data, we see that transmissions in many severely impacted states began to slow down in July, despite limited interventions. This is especially notable in states like Arizona, Florida, and Texas. While we believe that changes in human behavior and changes in policy (such as mask mandates and closing of bars/nightclubs) certainly contributed to the decrease in transmission, it seems unlikely that these were the primary drivers behind the decrease. We believe that many regions obtained a certain degree of temporary herd immunity after reaching 10-35 percent prevalence under the current conditions. We call this 10-35 percent threshold the effective herd immunity threshold.
  • Indeed, that is more or less what was recently found by Youyang Gu, to date the best modeler of pandemic spread in the U.S
  • he cautioned again that he did not mean to imply that the natural herd-immunity level was as low as 10 percent, or even 35 percent. Instead, he suggested it was a plateau determined in part by better collective understanding of the disease and what precautions to take
  • Gu estimates national prevalence as just below 20 percent (i.e., right in the middle of his range of effective herd immunity), it still counts, I think, as encouraging — even if people in hard-hit communities won’t truly breathe a sigh of relief until vaccines arrive.
  • If you can get real protection starting at 35 percent, it means that even a mediocre vaccine, administered much more haphazardly to a population with some meaningful share of vaccination skeptics, could still achieve community protection pretty quickly. And that is really significant — making both the total lack of national coordination on rollout and the likely “vaccine wars” much less consequential.
  • At least 20 percent of the public, and perhaps 50 percent, had some preexisting, cross-protective T-cell response to SARS-CoV-2, according to one much-discussed recent paper. An earlier paper had put the figure at between 40 and 60 percent. And a third had found an even higher prevalence: 81 percent.
  • The T-cell story is similarly encouraging in its big-picture implications without being necessarily paradigm-changing
  • These numbers suggest their own heterogeneity — that different populations, with different demographics, would likely exhibit different levels of cross-reactive T-cell immune response
  • The most optimistic interpretation of the data was given to me by Francois Balloux, a somewhat contrarian disease geneticist and the director of the University College of London’s Genetics Institute
  • According to him, a cross-reactive T-cell response wouldn’t prevent infection, but would probably mean a faster immune response, a shorter period of infection, and a “massively” reduced risk of severe illness — meaning, he guessed, that somewhere between a third and three-quarters of the population carried into the epidemic significant protection against its scariest outcomes
  • the distribution of this T-cell response could explain at least some, and perhaps quite a lot, of COVID-19’s age skew when it comes to disease severity and mortality, since the young are the most exposed to other coronaviruses, and the protection tapers as you get older and spend less time in environments, like schools, where these viruses spread so promiscuously.
  • Balloux told me he believed it was also possible that the heterogeneous distribution of T-cell protection also explains some amount of the apparent decline in disease severity over time within countries on different pandemic timelines — a phenomenon that is more conventionally attributed to infection spreading more among the young, better treatment, and more effective protection of the most vulnerable (especially the old).
  • Going back to Youyang Gu’s analysis, what he calls the “implied infection fatality rate” — essentially an estimated ratio based on his modeling of untested cases — has fallen for the country as a whole from about one percent in March to about 0.8 percent in mid-April, 0.6 percent in May, and down to about 0.25 percent today.
  • even as we have seemed to reach a second peak of coronavirus deaths, the rate of death from COVID-19 infection has continued to decline — total deaths have gone up, but much less than the number of cases
  • In other words, at the population level, the lethality of the disease in America has fallen by about three-quarters since its peak. This is, despite everything that is genuinely horrible about the pandemic and the American response to it, rather fantastic.
  • there may be some possible “mortality displacement,” whereby the most severe cases show up first, in the most susceptible people, leaving behind a relatively protected population whose experience overall would be more mild, and that T-cell response may play a significant role in determining that susceptibility.
  • That, again, is Balloux’s interpretation — the most expansive assessment of the T-cell data offered to me
  • The most conservative assessment came from Sarah Fortune, the chair of Harvard’s Department of Immunology
  • Fortune cautioned not to assume that cross-protection was playing a significant role in determining severity of illness in a given patient. Those with such a T-cell response, she told me, would likely see a faster onset of robust response, yes, but that may or may not yield a shorter period of infection and viral shedding
  • Most of the scientists, doctors, epidemiologists, and immunologists I spoke to fell between those two poles, suggesting the T-cell cross-immunity findings were significant without necessarily being determinative — that they may help explain some of the shape of pandemic spread through particular populations, but only some of the dynamics of that spread.
  • he told me he believed, in the absence of that data, that T-cell cross-immunity from exposure to previous coronaviruses “might explain different disease severity in different people,” and “could certainly be part of the explanation for the age skew, especially for why the very young fare so well.”
  • the headline finding was quite clear and explicitly stated: that preexisting T-cell response came primarily via the variety of T-cells called CD4 T-cells, and that this dynamic was consistent with the hypothesis that the mechanism was inherited from previous exposure to a few different “common cold” coronaviruses
  • “This potential preexisting cross-reactive T-cell immunity to SARS-CoV-2 has broad implications,” the authors wrote, “as it could explain aspects of differential COVID-19 clinical outcomes, influence epidemiological models of herd immunity, or affect the performance of COVID-19 candidate vaccines.”
  • “This is at present highly speculative,” they cautioned.

Should The Government Pay People To Get Vaccinated? Some Economists Think So : NPR - 0 views

  • the country will likely need a vaccination level of between 70% and 90% to reach herd immunity
  • The idea of a cash-for-shots program is being promoted by some economists and politicians in case the country struggles to get to herd immunity this year.
  • Here's how his idea works: Everyone who gets vaccinated would be eligible for a $1,000 payment from the federal government. You'd get $200 for taking both vaccine shots. And then an additional $800 once the country reaches herd immunity.
  • ...8 more annotations...
  • The idea is textbook economics. People respond to incentives.
  • incentives can be used not just for the sake of individuals, but for the benefit of society as a whole.
  • it would be a drop in the bucket compared to the economic harm if the pandemic persists.
  • His plan would cost the country between $250 billion and $300 billion.
  • "Payments may indeed encourage some people to get the vaccine," says Cynthia Cryder, an associate professor of marketing at Washington University's Olin Business School. "But it may also deter people from getting the vaccine. Because payments signal that the vaccine is risky."
  • Another method of getting to herd immunity may exist, though it has not been discussed widely. Mandates — requiring people to get vaccinated either by orders of state governments or employers.
  • To economist Robert Litan, if we ultimately must choose between the carrot of cash payouts and the stick of mandated vaccines, the answer is clear: the carrot.
  • "I think the level of anger in the country will go up extraordinarily high if we had mandates," he says.

Polling's Secrecy Problem - NYTimes.com - 0 views

  • In the polling world, no survey firm releases its microdata in a timely manner. When pollsters release it at all — usually months after publication, to an archive that requires a paid subscription for access — they seldom provide the detailed methodological explanations necessary to replicate the survey results.
  • Critics have raised charges of full-scale fabrication, like that alleged in the LaCour study, about a handful of pollsters in recent years, and such a wholly fraudulent poll might well be able to evade detection.
  • But a bigger problem is that pollsters may be using questionable means to ensure that their results end up in a certain place. Any poll is required to make judgments about exactly how to weight the sample or decide who is likely to vote. But such choices can swing the results by several percentage points, and these decisions can be made with the results in mind.
  • ...5 more annotations...
  • In particular, there is reason to think that pollsters engage in a behavior known as herding, in which they announce results that are similar to those of other recent polls
  • There is strong evidence that some firms have engaged in herding.
  • The firm has since switched to more conventional weighting techniques, bringing the wild swings in the racial composition of the electorate to an end. Its findings now resemble those of other pollsters: offering no obvious signs of herding, but also not providing the data that would rule it out.
  • the association recently began a transparency initiative intended to address some of the concerns.But few polling organizations have signed up so far, and the transparency initiative’s disclosure standards generally fall short of what is needed to allow others researchers to identify or deter dubious practices.
  • It’s hard to say what’s more telling: that the transparency standards wouldn’t be enough to preclude bad practices, or that so few pollsters seem willing to adhere to even those requirements.

The herd mentality is all around us - 0 views

  • “Personal space” and the idea of being left alone with one’s thoughts can almost be seen as modern add-ons to what humanity is like, and perhaps more typical of WEIRD (Western, educated, industrialized, rich and democratic) societies than others
  • WEIRD-ness being the coinage of Joseph Henrich, an anthropologist at Harvard and the author of “The WEIRDest People in the World: How the West Became Psychologically Peculiar and Particularly Prosperous.” Reviewing the book for The Times, the Tufts University philosophy professor Daniel Dennett described Henrich’s concept thusly:The world today has billions of inhabitants who have minds strikingly different from ours. Roughly, we weirdos are individualistic, think analytically, believe in free will, take personal responsibility, feel guilt when we misbehave and think nepotism is to be vigorously discouraged, if not outlawed.
  • They (the non-WEIRD majority) identify more strongly with family, tribe, clan and ethnic group, think more “holistically,” take responsibility for what their group does (and publicly punish those who besmirch the group’s honor), feel shame — not guilt — when they misbehave and think nepotism is a natural duty.
  • ...7 more annotations...
  • There are signs that at the same time, so many other people are seeking to countenance diversity of thought, disavowing the comforts of the idea that their view is the only legitimate one and fostering an ideal under which our society frames difference of opinion as a norm rather than a threat. We can see it in aspects of linguistic behavio
  • To us WEIRD-os, by contrast, the ever-stronger purchase of individualism in our intellectual, moral and civic development seems natural. But it’s challenging, perhaps unnatural, to be an individual.
  • That realization makes less shocking to me, albeit utterly dismaying, the many dogmatic behaviors exhibited today that seem outwardly irrational or close to it. The kinds of things that make it seem as if so many of us are, so to speak, losing it are actually signs of how difficult it can be to get past what we seem to be hard-wired for. Fanatic beliefs, furious ideologies and even, potentially, a sense of duty to harm people in the name of certain beliefs reflect the eternal temptation of a sense of belonging to a group, of being part of a larger story, of having a guiding sense of purpose.
  • Casual American English, in ways we’re not always conscious of, is more overt in allowing room for disagreement than it used to be. For example, the use of “like” that so bothers purists is in reality a useful discursive hedge, along with phrases such as “sort of,” “kind of” and “you know.” In conversation, these expressions can be read as subtle indications that someone knows that there are other ways to view things, and to be too categorical is to imply a certainty that all may not share.
  • Moral Courage College, an alternative to the D.E.I. ritual, a program offering training in how to productively grapple with the wide range of views and experiences found in most workplaces, as well as colleges, universities and even K-12 schools
  • a method called Diversity Without Division. “This program doesn’t tell anybody what to think or believe,” she has said, “it teaches everybody to lower their emotional defenses so that contentious issues can be turned into constructive conversations and healthy teamwork.”
  • Courage is allowing that your own view may be but one legitimate one among many, that there are no easy answers, and that being your own self is a more gracious existence than joining a herd.

Covid-19: How Much Herd Immunity is Enough? - The New York Times - 0 views

What Biden's May 1 COVID-19 Vaccine Deadline Means For You | HuffPost Life - 0 views

  • President Joe Biden also said in an address on Thursday that all Americans would be eligible for a COVID-19 vaccine by May 1
  • Now, this does not necessarily mean everyone in the country will be rolling up their sleeves on that day. The general public may start scheduling appointments in early May, but it’s probably going to take a few months to work through the general population.
  • So far, the vaccine rollout has been sticky — it’s difficult to secure an appointment and supply continues to be tight across the country.
  • ...7 more annotations...
  • The country will also need to open more vaccination sites, some of which should be open 24/7 to ensure people who get off work at odd hours have easy access to the vaccine.“This is a wartime sort of response,” Fagbuyi said. “You’re going to pull all the stops and not leave any stone unturned.”
  • “Enjoy the opportunity, but also be cautious and look at what’s going on around you,” Fagbuyi said.
  • So, when will we get to a point where it won’t be so complicated for the general public to score a vaccine appointment? Fagbuyi predicts sometime in June.
  • Adalja predicts that by the Fourth of July, vulnerable people will be vaccinated in all states and there will no longer be concerns about reaching hospital capacity.
  • “We’re going to be trying to convince people to come get vaccinated,” Adalja said.
  • We often hear doctors say we want 70% of the population to be immune to COVID-19, whether through vaccination, natural infection or preexisting immunity, to achieve herd immunity. Each dose pricked in someone’s arm makes it harder for the virus to spread.
  • “What I think is more important than herd immunity is making sure vulnerable populations are vaccinated so that COVID loses the ability to cause severe illness, hospitalization and death,” Adalja said.

Pfizer Begins Testing Its Vaccine in Young Children - The New York Times - 0 views

  • Pfizer Begins Testing Its Vaccine in Young Children
  • Other drug makers have begun similar trials of their Covid-19 vaccines. If they work in children younger than 12 as expected, it will be easier for the U.S. to reach herd immunity.
  • Pfizer has begun testing its Covid-19 vaccine in children under 12, a significant step in turning back the pandemic.

  • The trial’s first participants, a pair of 9-year-old twin girls, were immunized at Duke University in North Carolina on Wednesday.
  • Immunizing children will help schools to reopen as well as help to end the pandemic, said Dr. Emily Erbelding, an infectious diseases physician at the National Institutes of Health who oversees testing of Covid-19 vaccines in special populations.

  • After determining the most effective dose, the company will test the vaccine in 4,500 children
  • “It sounds like a good plan, and it’s exciting that another Covid-19 vaccine is moving forward with trials in children,”
  • Children represent 13 percent of all reported cases in the United States.
  • More than 3.3 million children have tested positive for the virus, at least 13,000 have been hospitalized and at least 260 have died
  • “We don’t know what the long-term effects of Covid infection are going to be,” Dr. Maldonado said.
  • Other vaccines have helped to control many horrific childhood diseases that can cause long-term complications, she added: “For some of us who’ve seen that, we don’t want to go back to those days.”

  • Digital bulletin-board systems—proto–group chats, you could say—date back to the 1970s, and SMS-style group chats popped up in WhatsApp and iMessage in 2011.

  • In every group chat, no matter the size, participants fall into informal roles. There is usually a leader—a person whose posting frequency drives the group or sets the agenda. Often, there are lurkers who rarely chime in
  • Larger group chats are not immune to the more toxic dynamics of social media, where competition for attention and herd behavior cause infighting, splintering, and back-channeling.
  • It’s enough to make one think, as the writer Max Read argued, that “venture-capitalist group chats are a threat to the global economy.” Now you might also say they are a threat to national security.
  • thanks to the private nature of the group chats, this information largely stayed out of the public eye. As Bloomberg reported, “By the time most people figured out that a bank run was a possibility … it was already well underway.”
  • The investor panic that led to the swift collapse of Silicon Valley Bank in March was effectively caused by runaway group-chat dynamics. “It wasn’t phone calls; it wasn’t social media,” a start-up founder told Bloomberg in March. “It was private chat rooms and message groups.
  • Unlike traditional social media or even forums and message boards, group chats are nearly impossible to monitor.

Where social networks create a context collapse—a process by which information meant for one group moves into unfamiliar networks and is interpreted by outsiders—group chats seem to be context amplifiers
  • group chats provide strong relationship dynamics, and create in-jokes and lore. For decades, researchers have warned of the polarizing effects of echo chambers across social networks; group chats realize this dynamic fully.
  • Weird things happen in echo chambers. Constant reinforcement of beliefs or ideas might lead to group polarization or radicalization. It may trigger irrational herd behavior such as, say, attempting to purchase a copy of the Constitution through a decentralized autonomous organization

How Facebook Warps Our Worlds - The New York Times - 0 views

  • THOSE who’ve been raising alarms about Facebook are right: Almost every minute that we spend on our smartphones and tablets and laptops, thumbing through favorite websites and scrolling through personalized feeds, we’re pointed toward foregone conclusions. We’re pressured to conform

Immerse yourself in the habits and daily patterns of that existence and stay there long enough to get acculturated. Stay there long enough so that you forget the herd mentality of our partisan culture.
  • When you return home, you will look at your own place with foreign eyes. You’ll see the contours of your own reality more clearly. When you return to native ground, you’re more likely to possess the sort of perceptiveness that Isaiah Berlin says is the basis of political judgment.
  • This sort of wisdom consists of “a special sensitiveness to the contours of the circumstances in which we happen to be placed; it is a capacity for living without falling foul of some permanent condition or factor which cannot be either altered, or even fully described.” This wisdom is based on a tactile awareness of your country and its people — what they want, how they react. You don’t think this awareness. You feel it. You experience a visceral oneness with culture and circumstance — the smell of the street, tinges of anger and hope and aspiration. The irony is that you are more likely to come into union with your own home culture after you have been away from it.

We are cognitive misers; we try to think as little as possible. We are herd thinkers and conform our perceptions to fit in with the group.

Jonah Lehrer on the Wisdom and Foolishness of Crowds | Head Case - WSJ.com - 1 views

  • America depends upon the wisdom of crowds.
  • The wisdom of crowds turns out to be an incredibly fragile phenomenon. It doesn't take much for the smart group to become a dumb herd. Worse, a new study by Swiss scientists suggests that the interconnectedness of modern life might be making it even harder to benefit from our collective intelligence.
  • All of a sudden, the range of guesses dramatically narrowed; people were mindlessly imitating each other. Instead of canceling out their errors, they ended up magnifying their biases, which is why each round led to worse guesses. Although these subjects were far more confident that they were right—it's reassuring to know what other people think—this confidence was misplaced.

Journalists debunk vaccine science denial - 0 views

  • It summarized and condemned the scientific and medical fraud that the British researcher Andrew Wakefield perpetrated. Years earlier, he had falsely linked the measles, mumps, and rubella (MMR) vaccine to autism. The editorial lamented that “the damage to public health continues, fuelled by unbalanced media reporting and an ineffective response from government, researchers, journals, and the medical profession.”
  • Reporters also seek to ensure that viewers, listeners, or readers understand that measles can afflict a victim more powerfully than does a mere passing ailment.
  • Measles doesn’t spread in most U.S. communities because people are protected by “herd immunity,” meaning that 92% to 94% of the population is vaccinated or immune. That level of protection makes it hard for one case of measles to spread even from one unvaccinated person to another without direct contact.
  • a study that “found that only 51 percent of Americans were confident that vaccines are safe and effective, which is similar to the proportion who believe that houses can be haunted by ghosts.”
  • In some parts of California, resistance to vaccinations including the MMR shot is stronger than ever, despite cases of measles hitting five US states.
  • “Vaccines are a great idea, but they are poisoning us, adding things that kick in later in life so they can sell us more drugs.”
  • Health professionals say those claims are unfounded or vastly overstated.
  • “the anti-vaccination movement is fueled by an over-privileged group of rich people grouped together who swear they won’t put any chemicals in their kids (food or vaccines or whatever else), either because it’s trendy to be all-natural or they don’t understand or accept the science of vaccinations. Their science denying has been propelled further by celebrities
  • the outbreak “should worry and enrage the public.” It indicted the anti-vaxxers’ “ignorant and self-absorbed rejection of science” and declared, “Getting vaccinated is good for the health of the inoculated person and also part of one’s public responsibility to help protect the health of others.”
  • “It’s wrong,” the editors emphasized, “to allow public health to be threatened while everyone else waits for these science-denying parents to open their eyes.”
  • “It’s because these people are highly educated and they get on the Internet and read things and think they can figure things out better than their physician.”
  • linked vaccination opposition to the “political left, which has long been suspicious of the lobbying power of the pharmaceutical industry and its influence on government regulators, and also the fringe political right, which has at different times seen vaccination, fluoridisation and other public-health initiatives as attempts by big government to impose tyrannical limits on personal freedom.”
  • Attempts to increase concerns about communicable diseases or correct false claims about vaccines may be especially likely to be counterproductive.
  • “attempting balance by giving vaccine skeptics and pro-vaccine advocates equal weight in news stories leads people to believe the evidence for and against vaccination is equally strong.”
  • A recent edition of the Washington Post carried a letter defending anti-vaxxers as “people who generally are pro-science and highly educated, who have high incomes and who have studied this issue carefully before coming to the conclusion that the risk to their children is greater than the slim possibility of contracting a childhood disease that [in many cases leaves] little or no residual consequences.”

Pfizer Begins Testing Its Vaccine in Young Children - The New York Times - 0 views

  • Pfizer has begun testing its Covid-19 vaccine in children under 12, a significant step in turning back the pandemic.
  • Both companies have been testing their vaccines in children 12 and older, and expect those results in the next few weeks.

  • “It sounds like a good plan, and it’s exciting that another Covid-19 vaccine is moving forward with trials in children,”
  • More than 3.3 million children have tested positive for the virus, at least 13,000 have been hospitalized and at least 260 have died,
  • Other vaccines have helped to control many horrific childhood diseases that can cause long-term complications,

When Will We Need COVID-19 Vaccine Boosters? Here's What We Know So Far. | HuffPost Life - 1 views

  • The COVID-19 vaccination rollout is well underway in the United States. Millions of people have already been vaccinated, and states are beginning to widely expand eligibility.
  • Though experts are hopeful that we’ll reach herd immunity by the fall if vaccinations continue at our current pace, there are questions about the need for booster shots and how long our current immunizations will last.
  • At this point, the conversation on the need for booster shots for COVID-19 is still slightly hypothetical, although vaccine manufacturers and researchers are already preparing for the possibility by testing boosters and vaccines adjusting for known coronavirus variants.
  • ...2 more annotations...
  • “We have not seen any variants evade the vaccination completely,” Javaid said.
  • Right now we use antibody testing as a marker of an immune response. But we need more time to pass to study the population’s response to the vaccines before being able to sufficiently assess the duration of immunity.

Farmers Are Feeling The Pain As Drought Spreads In The Northwest : NPR - 2 views

  • Nicole Berg's stunted wheat field is so short and sparse she doesn't think the combine can even reach the wheat without, as she puts it, eating rocks.
  • Northwest farmers like Berg, and ranchers who depend on rain, are expecting what one farmer called a "somber harvest" this year.
  • Little moisture since February in wide swaths of the region is to blame. And drought is deepening across the West, with federal drought maps showing massive and growing areas of red.
  • ...7 more annotations...
  • She says with all the Western wildfires in recent years, the wild grass and forage seeds have become expensive.
  • The region is parched from near the Canadian border clear to the edge of Nevada, with triple digit temps on the way making it worse.
  • Earlier this year, Oregon declared drought zones for eight counties, and six more have requested it since. Now the drought is rapidly expanding into usually cooler and wetter western Oregon, according to Ryan Andrews, a hydrologist for the state's Water Resources Department.
  • Jeff Marti, a drought expert for Washington's Department of Ecology, says it hasn't been this dry since the 1920s.
  • "It's the story of the irrigation haves and the have nots," he says. "Meaning those folks who get their water from rivers or storage, are probably going to be fine for their irrigation needs. But the dryland users and the folks that have cattle that depend on forage on the rangelands may be more challenged."
  • He says it's hard to lose animals and bloodlines that he's worked so hard to build up. He figures it could take him up to a decade to build his herd back up without going into debt.
  • Most ranchers say they don't have time to dwell on the trucked-off cattle or lost crops. They're busy applying for federal disaster aid. And they're also keeping an eye out for wildfires that are always top-of-mind in the dry, hot summer, but expected to be worse because of this year's terrible drought.

    Farmers a dependent on Rain fall for the soil and for the crops and with this shortage especially in the mid-west it's hard for the farmers to make money.

As more are vaccinated, it makes economic sense to gradually open the economy, study fi... - 1 views

  • A University of New Mexico research team conducted a data analysis that has found that as a larger portion of the population gets vaccinated against COVID-19, it becomes economically advantageous to start relaxing social distancing measures and open businesses.
  • The study looked at data from four metropolitan statistical areas (MSAs) within the United States: Seattle, New York City, Los Angeles and Houston from January 21 to July 8, 2020. The four cities were chosen because they have had divergent trends with the virus (Seattle and New York City were early hotspots, while Los Angeles and Houston peaked in the summer).
  • "Our work is quantitative, so it can hopefully offer some evidence that shows the vaccines are going to allow us to loosen social distancing measures, including opening businesses," he said. "It provides a measure of hope as we go forward and increase the percentage of citizens who are vaccinated."
  • ...7 more annotations...
  • Sorrentino said the study defined economic impact by the extent that a city's economy was closed -- businesses like restaurants, gyms, salons and airports that would lose business without people's physical presence.
  • The study took into account both the costs associated with quarantining (which requires supervision costs as well as costs due to lowered productivity) as well as social distancing (which incurs costs only due to productivity).
  • "But our model shows that even before we achieve herd immunity, we can relax social distancing compared to the situation prior to immunization."
  • The analysis looked at Seattle, beginning on December 14, 2020, when the vaccine was first being administered. Even with this limited data, the effect of vaccinations was dramatic, impacting the so-called "optimal control solution."
  • While the optimal interventions would vary depending on a number of factors, we always saw that a gradual relaxation of social distancing was possible after roughly 10% of the population got vaccinated," he said.
  • After just 20 days, the trend was becoming clear when comparing with the case in which the effects of vaccinations were not incorporated in the model.
  • Sorrentino emphasizes also that everyone should continue to follow the current policy and health guidelines, and that the relaxing of social distancing should adhere to these guidelines and be gradual. And of course, that guidance may change, based on the rates of spread of the virus and the variants.
