The coronavirus vaccines made by Pfizer-BioNTech and Moderna may have caused heart problems in more than 1,200 Americans, including about 500 who were younger than age 30, according to data reported on Wednesday by researchers at the Centers for Disease Control and Prevention. Still, the benefits of immunization greatly outweighed the risks, and advisers to the C.D.C. strongly recommended vaccination for all Americans 12 and older. The New York Times: The heart problems reported are myocarditis, an inflammation of the heart muscle; and pericarditis, inflammation of the lining around the heart. The risk is higher after the second dose of an mRNA vaccine than after the first, the researchers reported, and much higher in men than in women. But overall, the side effect is very uncommon -- just 12.6 cases per million second doses administered. The researchers estimated that out of a million second doses given to boys ages 12 to 17, the vaccines might cause a maximum of 70 myocarditis cases, but would prevent 5,700 infections, 215 hospitalizations and two deaths. Agency researchers presented the data to members of the Advisory Committee on Immunization Practices, which makes recommendations on vaccine use in the United States. (The scientists grouped pericarditis with myocarditis for reporting purposes.) Most cases were mild, with symptoms like fatigue, chest pain and disturbances in heart rhythm that quickly cleared up, the researchers said. Of the 484 cases reported in Americans under age 30, the C.D.C. has definitively linked 323 cases to vaccination. The rest remain under investigation.

UPDATE (7/30): All the missing virus sequences have now been published, with their deletion being explained as just "an editorial oversight by a scientific journal," according to the New York Times.

In Slashdot's original report, an anonymous reader quoted another report from The New York Times: About a year ago, genetic sequences from more than 200 virus samples from early cases of Covid-19 in Wuhan disappeared from an online scientific database. Now, by rooting through files stored on Google Cloud, a researcher in Seattle reports that he has recovered 13 of those original sequences -- intriguing new information for discerning when and how the virus may have spilled over from a bat or another animal into humans. The new analysis, released on Tuesday, bolsters earlier suggestions that a variety of coronaviruses may have been circulating in Wuhan before the initial outbreaks linked to animal and seafood markets in December 2019. As the Biden administration investigates the contested origins of the virus, known as SARS-CoV-2, the study neither strengthens nor discounts the hypothesis that the pathogen leaked out of a famous Wuhan lab. But it does raise questions about why original sequences were deleted, and suggests that there may be more revelations to recover from the far corners of the internet.
UPDATE (6/25): The Washington Post notes the data wasn't exactly suppressed. "Processed forms of the same data were included in a preprint paper from Chinese scientists posted in March 2020 and, after peer review, published that June in the journal Small." And in addition: The NIH released a statement Wednesday saying that a researcher who originally published the genetic sequences asked for them to be removed from the NIH database so that they could be included in a different database. The agency said it is standard practice to remove data if requested to do so...

Bloom's paper acknowledges that there are benign reasons why researchers might want to delete data from a public database. The data cited by Bloom are not alone in being removed by the NIH during the pandemic. The agency, in response to an inquiry from The Post, said the National Library of Medicine has so far identified eight instances since the start of the pandemic when researchers had withdrawn submissions to the library.

"This one from China and the rest from submitters predominantly in the U.S.," the NIH said in its response. "All of those followed standard operating procedures."
The New York Times writes: The genetic sequences of viral samples hold crucial clues about how SARS-CoV-2 shifted to our species from another animal, most likely a bat. Most precious of all are sequences from early in the pandemic, because they take scientists closer to the original spillover event. As [Jesse Bloom, a virologist at the Fred Hutchinson Cancer Research Center who wrote the new report] was reviewing what genetic data had been published by various research groups, he came across a March 2020 study with a spreadsheet that included information on 241 genetic sequences collected by scientists at Wuhan University. The spreadsheet indicated that the scientists had uploaded the sequences to an online database called the Sequence Read Archive, managed by the U.S. government's National Library of Medicine. But when Dr. Bloom looked for the Wuhan sequences in the database earlier this month, his only result was "no item found." Puzzled, he went back to the spreadsheet for any further clues. It indicated that the 241 sequences had been collected by a scientist named Aisi Fu at Renmin Hospital in Wuhan. Searching medical literature, Dr. Bloom eventually found another study posted online in March 2020 by Dr. Fu and colleagues, describing a new experimental test for SARS-CoV-2. The Chinese scientists published it in a scientific journal three months later. In that study, the scientists wrote that they had looked at 45 samples from nasal swabs taken "from outpatients with suspected Covid-19 early in the epidemic." They then searched for a portion of SARS-CoV-2's genetic material in the swabs. The researchers did not publish the actual sequences of the genes they fished out of the samples. Instead, they only published some mutations in the viruses.

But a number of clues indicated to Dr. Bloom that the samples were the source of the 241 missing sequences. The papers included no explanation as to why the sequences had been uploaded to the Sequence Read Archive, only to disappear later. Perusing the archive, Dr. Bloom figured out that many of the sequences were stored as files on Google Cloud. Each sequence was contained in a file in the cloud, and the names of the files all shared the same basic format, he reported. Dr. Bloom swapped in the code for a missing sequence from Wuhan. Suddenly, he had the sequence. All told, he managed to recover 13 sequences from the cloud this way. With this new data, Dr. Bloom looked back once more at the early stages of the pandemic. He combined the 13 sequences with other published sequences of early coronaviruses, hoping to make progress on building the family tree of SARS-CoV-2. Working out all the steps by which SARS-CoV-2 evolved from a bat virus has been a challenge because scientists still have a limited number of samples to study. Some of the earliest samples come from the Huanan Seafood Wholesale Market in Wuhan, where an outbreak occurred in December 2019. But those market viruses actually have three extra mutations that are missing from SARS-CoV-2 samples collected weeks later. In other words, those later viruses look more like coronaviruses found in bats, supporting the idea that there was some early lineage of the virus that did not pass through the seafood market. Dr. Bloom found that the deleted sequences he recovered from the cloud also lack those extra mutations. "They're three steps more similar to the bat coronaviruses than the viruses from the Huanan fish market," Dr. Bloom said. This suggests, he said, that by the time SARS-CoV-2 reached the market, it had been circulating for awhile in Wuhan or beyond. The market viruses, he argued, aren't representative of full diversity of coronaviruses already loose in late 2019.
UPDATE (7/30): When republishing their sequences, the researchers indicated they actually came from January 30, 2020 (and not "late 2019").

Artificial intelligence is to be used to tackle the most deadly parasitic diseases in the developing world, tech company DeepMind has announced. The BBC reports: The London-based Alphabet-owned lab will work with the Drugs for Neglected Diseases initiative (DNDI) to treat Chagas disease and Leishmaniasis. Scientists spend years in laboratories mapping protein structures. But last year, DeepMind's AlphaFold program was able to achieve the same accuracy in a matter of days. Many diseases are linked to the roles of proteins in: catalysing chemical reactions (enzymes); fighting disease (antibodies); and acting as chemical messengers (hormones such as insulin). And knowing the 3D structure of a protein is important in developing treatments for, among others, cancer, dementia and infectious diseases.

Prof Dame Janet Thornton, of the European Bioinformatics Institute, told BBC News: "Most new drugs in recent years have been developed using protein-structural data as one part of the process. "There are, however, many other aspects which need to be taken into account, which, due to lack of data, may not be amenable to AI approaches." But the predictions would be "particularly valuable" for pathogens with unknown protein structures, including some neglected diseases. "Developing new AI approaches for designing such drugs is a new challenge but one to which the new AI techniques can be applied and this holds out great hope for the future," Dame Janet added.

Morgan Stanley plans to ban workers from its New York headquarters if they have not received a Covid-19 vaccine. The rule will apply to non-vaccinated guests and clients as well. From a report: According to a source close to the company, Morgan Stanley said in a memo to its employees in the New York metropolitan area that all staff working in buildings with a "large employee presence" are required to confirm their vaccination status by July 1. The source added that "vaccine attestation is on an honorary basis for employees, contingent workforce, clients and visitors." The company plans to expand the vaccination mandate to employees and guests in other Morgan Stanley locations in New York City and nearby Westchester starting July 12. "Operating within a fully vaccinated environment allows us to lift restrictions like the use of face coverings and the need to maintain physical distancing, returning to more normal office conditions," the source added.

Epic Systems' algorithm for identifying signs of sepsis, an often deadly complication from infections that can lead to organ failure, doesn't work as well as advertised, according to a new study published in JAMA Internal Medicine. The Verge reports: Epic says its alert system can correctly differentiate patients who do and don't have sepsis 76 percent of the time. The new study found it was only right 63 percent of the time. An Epic spokesperson disputed the findings in a statement to Stat News, saying that other research showed the algorithm was accurate. Sepsis is hard to spot early, but starting treatment as soon as possible can improve patients' chances of survival. The Epic system, and other automated warning tools like it, scan patient test results for signals that someone could be developing the condition. Around a quarter of US hospitals use Epic's electronic medical records, and hundreds of hospitals use its sepsis prediction tool, including the health center at the University of Michigan, where study author Karandeep Singh is an assistant professor.

The study examined data from nearly 40,000 hospitalizations at Michigan Medicine in 2018 and 2019. Patients developed sepsis in 2,552 of those hospitalizations. Epic's sepsis tool missed 1,709 of those cases, around two-thirds of which were still identified and treated quickly. It only identified 7 percent of sepsis cases that were missed by a physician. The analysis also found a high rate of false positives: when an alert went off for a patient, there was only a 12 percent chance that the patient actually would develop sepsis. Part of the problem, Singh told Stat News, seemed to be in the way the Epic algorithm was developed. It defined sepsis based on when a doctor would submit a bill for treatment, not necessarily when a patient first developed symptoms. That means it's catching cases where the doctor already thinks there's an issue. "It's essentially trying to predict what physicians are already doing," Singh said. It's also not the measure of sepsis that researchers would ordinarily use.

An anonymous reader quotes a report from The Guardian: From espresso to instant, coffee is part of the daily routine for millions. Now research suggests the brew could be linked to a lower chance of developing or dying from chronic liver disease. Chronic liver disease is a major health problem around the world. According to the British Liver Trust, liver disease is the third leading cause of premature death in the UK, with deaths having risen 400% since 1970. Writing in the journal BMC Public Health, Roderick and colleagues report how they analyzed data from 494,585 participants in the UK Biobank -- a project designed to help unpick the genetic and environmental factors associated with particular conditions. All participants were aged 40 to 69 when they signed up to the project, with 384,818 saying they were coffee drinkers at the outset compared with 109,767 who did not consume the beverage.

The team looked at the liver health of the participants over a median period of almost 11 years, finding 3,600 cases of chronic liver disease, with 301 deaths, and 1,839 cases of simple fatty liver disease. The analysis revealed that after taking into account factors such as body mass index, alcohol consumption, and smoking status, those who drank any amount of coffee, and of any sort, had a 20% lower risk of developing chronic liver disease or fatty liver disease (taken together) than those who did not consume the brew. The coffee drinkers also had a 49% lower risk of dying from chronic liver disease. The team said the magnitude of the effect increased with the amount of coffee consumed, up to about three to four cups a day, "beyond which further increases in consumption provided no additional benefit." A reduction in risk was also found when instant, decaffeinated and ground coffee were considered separately -- although the latter linked to the largest effect.

The highly contagious delta variant is the fastest and fittest coronavirus strain yet, and it will "pick off" the most vulnerable people, especially in places with low Covid-19 vaccination rates, World Health Organization officials warned Monday. From a report: Delta, first identified in India, has the potential "to be more lethal because it's more efficient in the way it transmits between humans and it will eventually find those vulnerable individuals who will become severely ill have to be hospitalized and potentially die," Dr. Mike Ryan, executive director of the WHO's emergencies program, said during a news conference. Ryan said world leaders and public health officials can help defend the most vulnerable through the donation and distribution of Covid vaccines. "We can protect those vulnerable people, those frontline workers," Ryan said, "and the fact that we haven't, as Director-General (Tedros Adhanom Ghebreyesus) has said, again and again, is a catastrophic moral failure at a global level." The WHO said Friday that delta is becoming the dominant variant of the disease worldwide. The agency declared delta a "variant of concern" last month. A variant can be labeled as "of concern" if it has been shown to be more contagious, more deadly or more resistant to current vaccines and treatments, according to the health organization.

USA Today reports: Companies like Moderna and Pfizer's partner BioNTech, whose names are familiar from COVID-19 vaccines, are using mRNA to spur cancer patients' bodies to make vaccines that will — hopefully — prevent recurrences and treatments designed to fight off advanced tumors. If they prove effective, which won't be known for at least another year or two, they could be added to the arsenal of immune therapies designed to get the body to fight off its own tumors...

Over the last decade, pharmaceutical companies around the world have been developing new ways to train the body's immune system to fight off tumors, particularly melanoma. They had learned how to remove a brake installed by tumors, unleashing the warriors of the immune system. Ten years ago, only about 5% of people with advanced melanoma survived for five years. Now, nearly half make it that long. Trials of mRNA cancer vaccines aim to boost that number even higher by adding soldiers to the fight... Once a tumor has been largely removed through surgery, a vaccine can help generate new immune soldiers known as T cells... A computer algorithm analyzes the mutations distinct to the cancer cells, looking for ones that trigger the production of T cells, said Melissa J. Moore, Moderna's chief scientific officer, of platform research. So far, she said, Moderna, working with partner Merck, has tested these personalized vaccines in about 100 patients. They aim eventually to make a personalized mRNA vaccine within about 45 days after the patient's cancer surgery, during their recovery...

Mutated cancer cells have proteins on their surface that can be targeted by an mRNA vaccine. For a tumor that has, say, five common mutations, a patient could get a combination of five of these vaccines. On Friday, BioNTech announced it was launching a new trial for this approach, testing it in 120 melanoma patients Europe, the United Kingdom, Australia and the U.S. The new treatment, given in connection with an antibody from Regeneron, is aimed at four tumor-associated antigens. More than 90% of melanoma tumors contain at least one of the four.
The U.S. federal government now lists 29 studies underway or that will be soon investigating mRNA cancer vaccines, according to the article.

And Dr. Stephen Hahn, who had a career as an oncologist before running the Food and Drug Administration from 2019 until early this year, "said he's more optimistic this time because of how much researchers have learned about the role the immune system plays in cancer. 'That gives us an edge to maybe finally get to the place where we need to be.'"

The U.S. government spent more than $18 billion last year funding drugmakers to make a Covid vaccine, an effort that led to at least five highly effective shots in record time. Now it's pouring more than $3 billion on a neglected area of research: developing pills to fight the virus early in the course of infection, potentially saving many lives in the years to come. From a report: The new program, announced on Thursday by the Department of Health and Human Services, will speed up the clinical trials of a few promising drug candidates. If all goes well, some of those first pills could be ready by the end of the year. The Antiviral Program for Pandemics will also support research on entirely new drugs -- not just for the coronavirus, but for viruses that could cause future pandemics. A number of other viruses, including influenza, H.I.V. and hepatitis C, can be treated with a simple pill. But despite more than a year of research, no such pill exists to treat someone with a coronavirus infection before it wreaks havoc. Operation Warp Speed, the Trump administration's program for accelerating Covid-19 research, invested far more money in the development of vaccines than of treatments, a gap that the new program will try to fill.

Dr. Anthony Fauci, the director of the National Institute of Allergy and Infectious Diseases and a key backer of the program, said he looked forward to a time when Covid-19 patients could pick up antiviral pills from a pharmacy as soon as they tested positive for the coronavirus or develop Covid-19 symptoms. "I wake up in the morning, I don't feel very well, my sense of smell and taste go away, I get a sore throat," Dr. Fauci said in an interview. "I call up my doctor and I say, 'I have Covid and I need a prescription.'" Dr. Fauci's support for research on antiviral pills stems from his own experience fighting AIDS three decades ago. In the 1990s, his institute conducted research that led to some of the first antiviral pills for H.I.V., "protease inhibitors" that block an essential virus protein and can keep the virus at bay for a lifetime.

California on Friday started offering residents a digital record of their coronavirus vaccinations that they can use to access businesses or events that require proof they got the shots. From a report: The state's public health and technology departments said the new tool allows Californians access to their COVID-19 vaccination records from the state's immunization registry and includes the same information as the paper cards issued by the Centers for Disease Control and Prevention. To access the information, Californians will enter into a state website their name, date of birth and email or phone associated with their vaccine records and they will be asked to create a four-digit PIN. The record will include a QR code that users can save to their mobile phones. With nearly 20 million people fully vaccinated in California and proof of vaccination already required in some circumstances such as travel, state health officials felt there would be demand for the tool, though it remains optional, said Dr. Erica Pan, the state's epidemiologist.

Apple Chief Executive Tim Cook has said the company's greatest contribution to mankind will be in health. So far, some Apple initiatives aimed at broadly disrupting the healthcare sector have struggled to gain traction, according to people familiar with them and documents reviewed by The Wall Street Journal. From the report: Apple has envisioned an audacious plan for healthcare, offering its own primary-care medical service with Apple-employed doctors at its own clinics, according to people familiar with the plan and documents. To test that and other bold healthcare ideas, it took over clinics that catered to its employees and built a team with scores of clinicians, engineers, product designers and others. Today those ambitions, which aren't widely known, have largely stalled as Apple has shifted the focus of its health unit to something it knows well: Selling devices, specifically the Apple Watch, according to people familiar with its strategy.

The new primary-care service hasn't gotten off the ground, people familiar with it say. A digital health app launched quietly this year has struggled to keep users engaged, say people familiar with the app and the documents seen by the Journal. Some employees have raised questions internally about the integrity of health data coming from the company's clinics that has been used to support product development, according to people familiar with their concerns and the documents.

The government in Pakistan's largest province, Punjab, has decided to block SIM cards of unvaccinated citizens, reports the Hindustan Times (one of the largest newspapers in India), citing reports from news agency ANI.
Dr. Rashid, the provincial health minister in Pakistan's Punjab, said that there has been a "considerable decrease" in Covid-19 cases in the province due to mass vaccinations. However, a report compiled by the Punjab primary health department shows that the province still failed to achieve its set target for Covid-19 vaccination, reports ARY News, adding that around 300,000 recipients of the first dose of the vaccine never returned for the second dose since the start of Pakistan's mass inoculation drive on February 2.

Linus Torvalds was "clearly unamused" by a "humanoid conspiracy theory, and also on its discussion in a Linux kernel topic thread," reports Neowin. They add that Torvalds "weighed in quite heavily with some very strong language, mixed with some biology lessons..."

Here's an excerpt from Torvalds' response (as shared by Slashdot reader Hmmmmmm): Please keep your insane and technically incorrect anti-vax comments to yourself.

You don't know what you are talking about, you don't know what mRNA is, and you're spreading idiotic lies. Maybe you do so unwittingly, because of bad education. Maybe you do so because you've talked to "experts" or watched youtube videos by charlatans that don't know what they are talking about.

But dammit, regardless of where you have gotten your mis-information from, any Linux kernel discussion list isn't going to have your idiotic drivel pass uncontested from me.

Vaccines have saved the lives of literally tens of millions of people.

Just for your edification in case you are actually willing to be educated: mRNA doesn't change your genetic sequence in any way. It is the exact same intermediate - and temporary - kind of material that your cells generate internally all the time as part of your normal cell processes, and all that the mRNA vaccines do is to add a dose their own specialized sequence that then makes your normal cell machinery generate that spike protein so that your body learns how to recognize it.

The half-life of mRNA is a few hours. Any injected mRNA will be all gone from your body in a day or two. It doesn't change anything long-term, except for that natural "your body now knows how to recognize and fight off a new foreign protein" (which then tends to fade over time too, but lasts a lot longer than a few days). And yes, while your body learns to fight off that foreign material, you may feel like shit for a while. That's normal, and it's your natural response to your cells spending resources on learning how to deal with the new threat.

And of the vaccines, the mRNA ones are the most modern, and the most targeted - exactly because they do *not* need to have any of the other genetic material that you traditionally have in a vaccine (ie no need for basically the whole - if weakened - bacterial or virus genetic material). So the mRNA vaccines actually have *less* of that foreign material in them than traditional vaccines do. And a *lot* less than the very real and actual COVID-19 virus that is spreading in your neighborhood.

Honestly, anybody who has told you differently, and who has told you that it changes your genetic material, is simply uneducated. You need to stop believing the anti-vax lies, and you need to start protecting your family and the people around you. Get vaccinated...

Get vaccinated. Stop believing the anti-vax lies.

And if you insist on believing in the crazy conspiracy theories, at least SHUT THE HELL UP about it on Linux kernel discussion lists.

A third member of a panel of outside advisers to the U.S. Food and Drug Administration has resigned in protest over the agency's decision to approve Biogen's Alzheimer's disease treatment despite the committee's recommendation against doing so. Reuters reports: Aaron Kesselheim, a Professor of Medicine at Harvard Medical School who had served on the FDA's advisory committee for nervous system drugs since 2015, told Reuters on Thursday he was stepping down from the panel. "My rationale was that the FDA needs to re-evaluate how it solicits and uses the advisory committees ... because I didn't think that the firm recommendations from the committee in this case ... were appropriately integrated into the decision-making process," Kesselheim said in an email. He cited FDA's decision to approve Sarepta Therapeutic's drug, eteplirsen, for Duchenne muscular dystrophy in 2016 as another example of the regulator approving a drug against the recommendations of its advisory committee.

On Tuesday, a member of the advisory group who voted against the approval, Washington University neurologist Dr. Joel Perlmutter, resigned from the committee, citing the FDA's approval of Aduhelm. Mayo Clinic neurologist Dr. David Knopman said he resigned on Wednesday. The 11-member committee voted nearly unanimously in November that Biogen's drug should not be approved, citing inconclusive evidence that the drug was effective.

PolygamousRanchKid shares a report from Gizmodo: A dose of laughing gas may just help some people with hard-to-treat depression, suggests a new, small clinical trial published Wednesday. The study found that people who inhaled nitrous oxide reported improvements in their depression symptoms afterward. It also found that people felt similar improvements with a smaller dose as they did with a larger one, but experienced substantially fewer side effects. Nitrous oxide (NO) is a colorless, non-flammable gas at room temperature that's long been used as an anesthetic and sometimes as a recreational drug, due to the euphoria and dissociative hallucinations it can cause upon inhalation. But several years ago, Peter Nagele, a researcher and trauma anesthesiologist at the University of Chicago, and his colleagues began looking into nitrous oxide as a potential treatment for depression.

The small trial recruited 28 participants in a crossover design, which is when all the volunteers go through each of the trial's conditions and their responses are compared to one another (as opposed to two or more distinct groups that either take the drug or placebo). The team found that these volunteers on average experienced a greater improvement in depression symptoms when they took the nitrous oxide at either dose than they did after taking the placebo (based on the primary survey they completed) -- an improvement that lasted for up to two weeks. Some doctors and patients had been using generic ketamine, taken through IV, as an experimental depression treatment for years. But Johnson & Johnson didn't fund expensive clinical trials to secure an approval for ketamine as a depression treatment; it instead developed a patentable form taken as a nasal spray, called esketamine. That sort of commercialization isn't something that's possible with nitrous oxide, according to Nagale. The study has been published in the journal Science Translational Medicine.

Dengue fever cases have been cut by 77% in a "groundbreaking" trial that manipulates the mosquitoes that spread it, say scientists. The BBC reports: They used mosquitoes infected with "miraculous" bacteria that reduce the insect's ability to spread dengue. The trial took place in Yogyakarta city, Indonesia, and is being expanded in the hope of eradicating the virus. The World Mosquito Programme team says it could be a solution to a virus that has gone around the world. The trial used mosquitoes infected with Wolbachia bacteria. One of the researchers, Dr Katie Anders, describes them as "naturally miraculous." Wolbachia doesn't harm the mosquito, but it camps out in the same parts of its body that the dengue virus needs to get into. The bacteria compete for resources and make it much harder for dengue virus to replicate, so the mosquito is less likely to cause an infection when it bites again.

The trial used five million mosquito eggs infected with Wolbachia. Eggs were placed in buckets of water in the city every two weeks and the process of building up an infected population of mosquitoes took nine months. Yogyakarta was split into 24 zones and the mosquitoes were released only in half of them. The results, published in the New England Journal of Medicine, showed a 77% reduction in cases and an 86% reduction in people needing hospital care when the insects were released.

The Biden administration is buying 500 million doses of Pfizer's coronavirus vaccine to donate to the world, as the United States dramatically increases its efforts to help vaccinate the global population, the Washington Post reported Wednesday, citing three people familiar with the plans. From the report: President Biden is slated to announce the plan at the G-7 meeting in Britain this week amid growing calls for the United States and other rich countries to play a more substantial role in boosting the global supply of vaccines. Biden told reporters Wednesday as he boarded Air Force One to Europe he would be announcing his global vaccine strategy. The Biden administration previously announced it would share at least 80 million vaccine doses with the world by the end of June. Last week, the White House detailed plans for how it would allocate 25 million doses, with about 19 million of them being shared with Covax, the World Health Organization-backed initiative to distribute vaccine doses around the globe. Roughly 6 million doses would be shared directly with countries experiencing severe coronavirus outbreaks, including India.

For more than a week, an average of about 20 million people have been vaccinated against COVID-19 every day in China. At this rate, the nation would have fully vaccinated the entire UK population in little more than six days. From a report: China now accounts for more than half of the 35 million or so people around the world receiving a COVID-19 shot each day. Zoltan Kis, a chemical engineer in the Future Vaccine Manufacturing Research Hub at Imperial College London, doesn't know of "anything even close to those production scales" for a vaccine. "The manufacturing efforts required in China to reach this high production throughput are tremendous," he says. The majority of doses are of one of two vaccines, both of which have been approved for emergency use worldwide by the World Health Organization (WHO). CoronaVac -- produced by Beijing-based company Sinovac -- showed an efficacy of 51% against symptoms of COVID-19 in clinical trials, and much higher protection against severe disease and death. The second jab was developed in Beijing by state-owned firm Sinopharm and has demonstrated an efficacy of 79% against symptomatic disease and hospitalization.

"A new kind of COVID-19 vaccine could be available as soon as this summer," reports NPR: It's what's known as a protein subunit vaccine. It works somewhat differently from the current crop of vaccines authorized for use in the U.S. but is based on a well-understood technology and doesn't require special refrigeration.

In general, vaccines work by showing people's immune systems something that looks like the virus but really isn't. Consider it an advance warning; if the real virus ever turns up, the immune system is ready to try to squelch it. In the case of the coronavirus, that "something" is one of the proteins in the virus — the spike protein. The vaccines made by Johnson & Johnson, Moderna and Pfizer contain genetic instructions for the spike protein, and it's up to the cells in our bodies to make the protein itself.

The first protein subunit COVID-19 vaccine to become available will likely come from the biotech company, Novavax. In contrast to the three vaccines already authorized in the U.S., it contains the spike protein itself — no need to make it, it's already made — along with an adjuvant that enhances the immune system's response, to make the vaccine even more protective.

Protein subunit vaccines made this way have been around for a while. There are vaccines on the market for hepatitis B and pertussis based on this technology.
And meanwhile, the article points out, there's also another company — the pharmaceutical giant Sanofi — that's also working on its own protein subunit vaccine against the coronavirus.

The American Heart Association is a research-funding nonprofit. One of its publications, The Journal of the American Heart Association, "has concurred with a previous report by the Heart Rhythm Journal which said close contact with an iPhone 12 affected certain implantable cardiac devices," writes Apple Insider. As with that report, the American Heart Association says the effect are solely when the iPhone is on or very near the implant... "Our study demonstrates that magnet reversion mode may be triggered when the iPhone 12 Pro Max is placed directly on the skin over an implantable cardiac device and thus has the potential to inhibit lifesaving therapies," say the report writers in the Journal of the American Heart Association. The testing involved placing the iPhone 12 Pro Max in very close proximity to a series of 11 different pacemakers and defibrillators... The degree of interference did vary across the testing, but all devices were affected. The report says that "the iPhone 12 Pro Max was able to trigger magnetic reversion mode at a distance up to 1.5cm [0.6 inches]."

"Apple Inc, has an advisory stating that the newer generation iPhone 12 does not pose a greater risk for magnet interference when compared to the older generation iPhones," notes the report. "However, our study suggests otherwise as magnet response was demonstrated in 3/3 cases in vivo..."

In January 2021, Apple updated its MagSafe support document to recommend that users keep the iPhone 12 six inches away from any medical implants.
