To beat Covid, we may need a good shot in the nose

‘Intranasal vaccines might stop the spread of the coronavirus more effectively than needles in arms...

‘Although injected vaccines do reduce symptomatic COVID cases, and prevent a lot of severe illness, they may still allow for asymptomatic infection. A person might feel fine, but actually harbor the virus and be able to pass it on to others. The reason is that the coronavirus can temporarily take up residence in the mucosa—the moist, mucus-secreting surfaces of the nose and throat that serve as our first line of defense against inhaled viruses. Research with laboratory animals suggests that a coronavirus infection can linger in the nose even after it has been vanquished in the lungs. That means it might be possible to spread the coronavirus after vaccination.

‘Enter the intranasal vaccine, which abandons the needle and syringe for a spray container that looks more like a nasal decongestant. With a quick spritz up the nose, intranasal vaccines are designed to bolster immune defenses in the mucosa, triggering production of an antibody known as immunoglobulin A, which can block infection. This overwhelming response, called sterilizing immunity, reduces the chance that people will pass on the virus.’

7 ways to reduce reluctance to take Covid vaccines

  1. It's not necessary to change the minds of committed anti-vaxxers; they are just a tiny slice of the population, and we can reach herd immunity without them.
  2. Facts alone will not persuade skeptics.
  3. Some minority groups, such as Black and Native Americans, have strong historical reasons to view health authorities with suspicion. Experts favor working closely with civic and faith leaders, admired athletes and other trusted figures within those groups.
  4. Low levels of vaccination, particularly among low-income communities, often reflect practical barriers.
  5. Talk about how popular the vaccine is.
  6. Overcome the human tendency to procrastinate.
  7. For forgetful types, simple reminders—by text or voice message—can be powerful.

Patently unfair: Can waivers help solve Covid vaccine inequality?

‘The World Trade Organization (WTO) General Council gathered virtually on Monday for the first of two days of talks amid increasing calls from civil society, states and nongovernmental actors to temporarily waive patents for COVID-19 vaccines and other coronavirus-related medical products. Endorsing a waiver on Friday, World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus said: “If not now, when?”

‘At the core of the discussion stands a proposal submitted in October by South Africa and India to suspend the WTO’s agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) for the duration of the coronavirus pandemic. The goal is to facilitate the transfer of technology and scientific knowledge to developing countries to ramp up the global production of vaccines and other necessary equipment.’

Vaccine apartheid or corona-utopia — 6 post-pandemic futures

‘There are two types of people in the post-pandemic world: those who have been vaccinated and those who haven’t. Now, national leaders across the world are considering making that official.

‘So-called immunity passes are already a reality in Israel. With nearly half of the adult population vaccinated, the government announced last month that gyms, hotels, pools and cultural events can reopen for people who can present a QR code proving their immunity. The U.K. is exploring a similar option, and in the EU, experts say a proposal for a “digital green pass” facilitating cross-border travel could easily find domestic applications...

‘Ethicists and public health advocates note that such passes would be wildly discriminatory right now, when vaccines are in shortage. But they could easily become reality once supply outstrips demand (at least in wealthy countries) and restaurants, hotels, airlines and cultural venues seek safe ways to reopen.

‘How they are managed, and how they are accepted, will determine whether immunity passes offer a return to normalcy or usher in some sort of dystopic sci-fi scenario. Using our crystal ball (and a good deal of reporting), POLITICO has compiled snapshots from six possible futures that might be lying in wait for us before the end of the year:

  1. Corona-utopia
  2. Vaccine apartheid
  3. Back to the future
  4. Legal limbo
  5. Whole new hassle
  6. Why bother?

Coronavirus fact-check #10: Why “new cases” are plummeting... ‘It's not vaccines, it's not lockdown’

‘Essentially, in two memos the WHO ensured future testing would be less likely to produce false positives and made it much harder to be labelled an “asymptomatic case”.

‘In short, logic would suggest we’re not in fact seeing a “decline in Covid cases” or a “decrease in Covid deaths” at all.

‘What we’re seeing is a decline in perfectly healthy people being labelled “covid cases” based on a false positive from an unreliable testing process. And we’re seeing fewer people dying of pneumonia, cancer or other disease have “Covid19” added to their death certificate based on testing criteria designed to inflate the pandemic.’

Will I have to wear a mask after getting the Covid vaccine? The science explained

‘Public health authorities want people to keep wearing masks and social distancing, even after they receive a vaccine. This might seem counterintuitive – after all, if someone gets a vaccine, aren’t they protected from the coronavirus?

‘The answer is complicated: the vast majority of people who are vaccinated will be protected from Covid-19, the disease caused by the SARS-CoV-2 virus. However, vaccinated people may still be able to transmit the virus, even though they do not display any symptoms. “We know now the vaccines can protect, but what we haven’t had enough time to really understand is – does it protect from spreading?” said Avery August, professor of immunology at Cornell University.

‘That is because the the SARS-CoV-2 virus may still colonize the respiratory tract, even as systemic immune cells protect the overall body from the disease it causes – Covid-19.’

Convalescent plasma did not improve patient outcomes compared with placebo group: Study

‘In a systematic review and meta-analysis published in JAMA, researchers evaluated treatment with convalescent plasma compared to standard of care or use of a placebo in randomized clinical trials (RCTs)—published through January 29, 2021. The researchers identified 10 total RCTs—4 published peer-reviewed studies and 6 unpublished studies—including a total of 11,782 COVID-19 patients. 

‘Overall, convalescent plasma did not significantly differ from placebo or standard of care for any of the major outcomes of interest: all-cause mortality, length of hospital stay, mechanical ventilation use, clinical improvement, clinical deterioration, and serious adverse events. The researchers noted that there was limited data available regarding clinical improvement, clinical deterioration, and serious adverse events in these studies.’ (Summary from John Hopkins Centre for Health Security newsletter of March 2)

China approves two more domestic Covid-19 vaccines for public use

‘China’s medical products regulator said on Thursday that it had approved two more COVID-19 vaccines for public use, raising the number of domestically produced vaccines that can be used in China to four. The two newly cleared vaccines are made by CanSino Biologics Inc (CanSinoBIO) and Wuhan Institute of Biological Products, an affiliate of China National Pharmaceutical Group (Sinopharm).

‘They join a vaccine from Sinovac Biotech approved earlier this month, and another from Sinopharm’s Beijing unit approved last year.

‘Prior to formal approval for wider public use by the National Medical Products Administration, millions of doses of the two Sinopharm vaccines and Sinovac shot had been administered in China’s vaccination program. The program targets select groups of people facing a higher risk of infection.’

Covid-19: Pfizer BioNTech vaccine reduced cases by 94% in Israel, shows peer reviewed study

‘The Pfizer BioNTech coronavirus vaccine produces as good results in the “real world” as have been previously documented in randomised trials.

‘A case control study, which has been peer reviewed and published in the New England Journal of Medicine, compared 596 618 people who were newly vaccinated in Israel and matched them to unvaccinated controls.1 Two doses of the mRNA vaccine reduced symptomatic cases by 94%, hospitalisation by 87%, and severe covid-19 by 92%, according to the data from the Clalit Institute for Research which is Israel’s biggest healthcare provider.

‘Researchers recorded the outcomes at three periods: days 14 to 20 after the first dose of vaccine, days 21 through 27 after the first dose, and day 7 after the second dose. In Israel, the second dose of vaccine is given on day 21 in line with the trials and the manufacturer’s recommendation. The UK is leaving a 12 week gap between doses.

‘During a mean follow-up of 15 days, 10 561 infections were documented of which 5996 were symptomatic covid-19 illness, 369 required hospitalisation, 229 were severe cases, and 41 resulted in death.

‘After one dose, during days 14 to 20, the vaccine effectiveness was 57% for symptomatic covid-19, 74% for hospitalisation, and 62% for severe disease. The estimated effectiveness in preventing death from covid-19 was 72% in the two to three weeks after the first dose. There was insufficient data to produce an estimate on the reduction in mortality in those who received two doses.

‘The study took place from 20 December 2020, when Israel’s national vaccination drive was launched, to 1 February 2021. It coincided with Israel’s third and largest wave of coronavirus infection and illness.’

UN vaccine plan is underway, but problems remain

‘As the coronavirus pandemic exploded worldwide last April, global organizations banded together to help ensure that the world’s most vulnerable people would get vaccines amid the rush for shots. The initiative known as COVAX was formed by the World Health Organization, the vaccines alliance GAVI and a coalition for epidemic innovations called CEPI.

‘COVAX is supposed to make deals to buy vaccines in bulk from drug companies and can also receive donated shots from rich countries. Poorer nations can receive free doses from the initiative — and wealthier ones can also buy from it, as a way of diversifying their supply.

‘But it has been dogged by shortages of cash and supplies as well as logistical hurdles — all while a handful of rich countries raced ahead with their vaccination campaigns.’

The scientist who’s been right about Covid-19 vaccines predicts what’s next

‘[Hilda] Bastian — an expert in analyzing clinical trial data, founding member of the Cochrane Collaboration, and a former National Institutes of Health official — has gone down rabbit holes before. There was the time she traveled the US on her own dime to research and take historical photos for a Wikipedia list of African American mathematicians.

‘But her obsession with vaccines in this pandemic has been especially fruitful: She’s called the race right at just about every turn...

‘Nearly a year into her project, I caught up with Bastian to ask where our blind spots are now and how she predicts the vaccine story — and the pandemic — will unfold. She talked about the need for health officials to acknowledge that coronavirus vaccines have potentially “big differences in efficacy and adverse events,” a time in the future when we may need Covid-19 vaccine boosters every year, and the problem of people in rich countries like the US shamelessly hogging vaccines.’

Why Covid vaccines are so difficult to compare

‘Given the demand for speed amid limited supplies, any effort to rank the vaccines must take into account not only their reported effectiveness, but also supplies, costs, the logistics of deploying them, the durability of the protection they offer and their ability to fend off emerging viral variants. Even so, many people might find it hard to look away from clinical-trial results that suggest an efficacy gap. So far, more than 200 million doses of coronavirus vaccines have been delivered, and data have been rolling in from clinical trials in several countries. The top-line results from those studies suggest a range of protection: from 95% efficacy for a vaccine made by Pfizer of New York City and BioNTech of Mainz, Germany, to about 70% suggested by initial results on a vaccine made by AstraZeneca of Cambridge and the University of Oxford, both in the United Kingdom.’

Medical oxygen scarce in Africa, Latin America amid virus

‘A crisis over the supply of medical oxygen for coronavirus patients has struck nations in Africa and Latin America, where warnings went unheeded at the start of the pandemic and doctors say the shortage has led to unnecessary deaths.

‘It takes about 12 weeks to install a hospital oxygen plant and even less time to convert industrial oxygen manufacturing systems into a medical-grade network. But in Brazil and Nigeria, as well as in less-populous nations, decisions to fully address inadequate supplies only started being made last month, after hospitals were overwhelmed and patients started to die.’

US National Institutes of Health launch new initiative to study “Long Covid”

Some of the initial underlying questions that this initiative hopes to answer are:

  • What does the spectrum of recovery from SARS-CoV-2 infection look like across the population?
  • How many people continue to have symptoms of COVID-19, or even develop new symptoms, after acute SARS-CoV-2 infection?
  • What is the underlying biological cause of these prolonged symptoms?
  • What makes some people vulnerable to this but not others?
  • Does SARS-CoV-2 infection trigger changes in the body that increase the risk of other conditions, such as chronic heart or brain disorders?

These initial research opportunities will support a combination of ongoing and new research studies and the creation of core resources. We anticipate subsequent calls for other kinds of research, in particular opportunities focused on clinical trials to test strategies for treating long-term symptoms and promoting recovery from infection.

We’re just rediscovering a 19th-century pandemic strategy

‘The first way to fight a new virus would once have been opening the windows...

‘Miasma theory—discredited, of course, by the rise of germ theory—held that disease came from “bad air” emanating from decomposing matter and filth. This idea peaked in the 19th century, when doctors, architects, and one particularly influential nurse, Florence Nightingale, became fixated on ventilation’s importance for health. It manifested in the physical layout of buildings: windows, many of them, but also towers erected for the sole purpose of ventilation and elaborate ductwork to move contaminated air outdoors. Historic buildings still bear the vestigial mark of these public-health strategies, long after the scientific thinking has moved on.

‘That era saw the rise of well-ventilated “Nightingale pavilions,” named after Florence Nightingale, who popularized the design in her 1859 book, Notes on Hospitals. As a nurse in the Crimean War, she saw 10 times more soldiers die of disease than of battle wounds. Nightingale began a massive hygiene campaign in the overcrowded hospitals, and she collected statistics, which she presented in pioneering infographics. Chief among her concerns was air. Notes even laid out exact proportions for 20-patient pavilions that could allow 1,600 cubic feet of air per bed.’

I was the Australian doctor on the WHO’s Covid-19 mission to China. Here’s what we found about the origins of the coronavirus

‘As part of the mission, we met the man who, on December 8, 2019, was the first confirmed COVID-19 case; he’s since recovered. We met the husband of a doctor who died of COVID-19 and left behind a young child. We met the doctors who worked in the Wuhan hospitals treating those early COVID-19 cases, and learned what happened to them and their colleagues. We witnessed the impact of COVID-19 on many individuals and communities, affected so early in the pandemic, when we didn’t know much about the virus, how it spreads, how to treat COVID-19, or its impacts.

‘We talked to our Chinese counterparts — scientists, epidemiologists, doctors — over the four weeks the WHO mission was in China. We were in meetings with them for up to 15 hours a day, so we became colleagues, even friends. This allowed us to build respect and trust in a way you couldn’t necessarily do via Zoom or email.

‘This is what we learned about the origins of SARS-CoV-2:

  • Animal origins, but not necessarily at the Wuhan markets
  • Frozen or refrigerated food not ruled out in the spread
  • Extremely unlikely the virus escaped from a lab

Coronavirus (Covid-19) infection survey: Characteristics of people testing positive for Covid-19 in England, 22 February 2021

‘The UK government published a report on the infection risk associated with various occupations, based on data on COVID-19 cases in England from September 2020-January 2021. The analysis compared the likelihood of testing positive for SARS-CoV-2 during the study period for 25 standardized occupation categories. The occupation-specific risk ranged from 2.1% to 4.8%, with an overall risk of 3.9%. None of the individual occupation groups had a statistically significant difference from the overall average; however, some of the occupations with the highest risk showed a significant increase over those with the lowest risk. 

‘Occupation groups at the upper end include professions such as teachers, law enforcement and prison staff, childcare and home care, and secretarial professions. Occupation categories with lower infection risk include professions such as farmers and gardeners; scientists, engineers, and researchers; legal, social work, and news media; and textiles and printing services.’ (Summary by John Hopkins Centre for Health Security)

Power jab: The rise of vaccine diplomacy

‘At the end of January the President of Chile, Sebastián Piñera, gave a speech on the tarmac of Santiago airport. ‘Today is a day of joy, excitement and hope,’ he said, standing in front of a Boeing 787 which had just arrived from Beijing. Inside it were two million vaccine doses produced by the Chinese company Sinovac. It was the first of two similar-sized shipments arriving that month.

‘A few days earlier, the President of Mexico, Andrés Manuel López Obrador, had emerged from Covid confinement to thank a ‘genuinely affectionate’ Vladimir Putin for pledging 24 million Sputnik doses to Mexico in the coming months. Hopes of vaccinating his country with the Pfizer vaccine had dissipated when supply dried up. Pfizer blamed ‘global shortages’, but here was the perfect opportunity for Putin to play the hero and to send the world a message: in times of need, Moscow, not Washington, saves the day.

‘This is vaccine diplomacy, the new great game. Nations which are hungry to compete with the West — and especially America — are using their homegrown coronavirus vaccines as a way of gaining influence. They are exchanging their vaccines for loyalty and acts of public obeisance.’

Breaking down the psychology of vaccine hesitancy

  • 40% of respondents fell into the enthusiastic camp and reported eagerness to get vaccinated as soon as possible.
  • Another 20% were in the watchful group, which means they weren't against the vaccine, but were worried about side effects and didn't want to be first in line.
  • 14% were classified as cost-anxious — they tended to be younger and live in rural areas, and they perceived that the costs of the vaccine in time and money exceeded the benefits.
  • 9% were system distrusters, who were more likely to be minorities, and believed the vaccine had not been adequately tested for their group.
  • The last 17% were conspiracy believers who tended to be Republican and had little fear of COVID-19 itself. They often subscribed to more outlandish and harmful theories about vaccines.

The end of Covid-19 pandemic? Johns Hopkins’ Dr Makary says probably

‘A February 18 Opinion piece in the Wall Street Journal is raising hopes, and possibly healthy skepticism, with its title and thesis being: “We’ll Have Herd Immunity by April.” The author is Dr. Martin Makary, a professor of health policy and management and public health expert at Johns Hopkins University. He notes that the media is under reporting on the dramatic fact that COVID-19 cases are down 77 percent just in the last six weeks. Largely this is, “because natural immunity from prior infection is far more common than can be measured by testing.” 

‘Applying some statistics to the case data, we could deduce the around 55 percent in the US have natural immunity. At the same time, vaccinations have been rolling out, and 15 percent of Americans have gotten a vaccine with the percentage rising fast. Based on these factors, “There is reason to think the country is racing toward an extremely low level of infection. As more people have been infected, most of whom have mild or no symptoms, there are fewer Americans left to be infected. At the current trajectory, I expect Covid will be mostly gone by April, allowing Americans to resume normal life.”

Inferring the effectiveness of government interventions against Covid-19

‘Governments are attempting to control the COVID-19 pandemic with nonpharmaceutical interventions (NPIs). However, the effectiveness of different NPIs at reducing transmission is poorly understood. We gathered chronological data on the implementation of NPIs for several European and non-European countries between January and the end of May 2020. We estimated the effectiveness of these NPIs, which range from limiting gathering sizes and closing businesses or educational institutions to stay-at-home orders. To do so, we used a Bayesian hierarchical model that links NPI implementation dates to national case and death counts and supported the results with extensive empirical validation. Closing all educational institutions, limiting gatherings to 10 people or less, and closing face-to-face businesses each reduced transmission considerably. The additional effect of stay-at-home orders was comparatively small.’

Experts answer the biggest Covid vaccine questions

‘The lack of informed messaging from the Trump administration, combined with the range of different COVID vaccines, the emergence of new coronavirus variants, and inconsistent state and municipal rollout plans, have caused confusion and driven vaccine hesitancy. Scientific American asked Namandjé Bumpus, a pharmacologist at Johns Hopkins Medicine in Baltimore, and Ashley Lauren St. John, an immunologist at Duke-NUS Medical School in Singapore to answer some of the biggest questions about the currently available COVID vaccines:

  • Should you get an authorized COVID vaccine now if you are eligible?
  • Should you get vaccinated if you have already had COVID?
  • How should you interpret vaccine efficacy—what does “95 percent efficacy” or “66 percent efficacy” even mean?
  • If you get the vaccine and still get infected, does the vaccine still make a difference? 
  • Will it prevent severe disease or death?
  • Do the vaccines protect against the new virus variants, including those first identified in the U.K., South Africa and Brazil?
  • What is the difference between mRNA and viral vector vaccines?
  • Is there a “best” vaccine?
  • Will the vaccine protect you from giving the virus to others?
  • Will the vaccine’s effectiveness “wear off” over time?
  • Should you be worried about allergic reactions to the vaccine?
  • How can you ensure you’re getting a legitimate, authorized vaccine?

Covid-19 infections falling worldwide but WHO warns against apathy

‘Reported daily coronavirus infections have been falling across the world for a month and on Tuesday (Feb 16) hit their lowest since mid-October, Reuters figures show, but health experts warned against apathy even as vaccines are being rolled out worldwide. Falls in infections and deaths coincide with lockdowns and severe curbs on gatherings and movement as governments weigh the need to stop successive waves of the pandemic with the need to get people back to work and children back to school.

‘But optimism over a way out of the crisis has been tempered by new variants of the virus, raising fears about the efficacy of vaccines. "Now is not the time to let your guard down," Maria Van Kerkhove, the World Health Organization's technical lead on COVID-19, told a briefing in Geneva.’

Can Covid vaccines stop transmission? Scientists race to find answers

‘Controlling the pandemic will require shots that prevent viral spread, but that feature is difficult to measure...

‘Preliminary analyses suggest that at least some vaccines are likely to have a transmission-blocking effect. But confirming that effect — and how strong it will be — is tricky because a drop in infections in a given region might be explained by other factors, such as lockdowns and behaviour changes. Not only that, the virus can spread from asymptomatic carriers, which makes it hard to detect those infections.

“These are among the hardest types of studies to do,” says Marc Lipsitch, an infectious-disease epidemiologist at the Harvard T. H. Chan School of Public Health in Boston, Massachusetts. “All of us are out there, hungrily trying to see what we can get out of little bits of data that do come out,” he says. Results from some studies are expected in the next few weeks.’

In an analysis of current supply deals for COVID-19 vaccines, the ONE Campaign said wealthy countries, such as the United States and Britain, should share the excess doses to “supercharge” a fully global response to the pandemic.

‘The advocacy group, which campaigns against poverty and preventable diseases, said a failure to do so would deny billions of people essential protection from the COVID-19-causing virus and likely prolong the pandemic. The report looked specifically at contracts with the five leading COVID-19 vaccine makers - Pfizer-BioNTech, Moderna, Oxford-AstraZeneca, Johnson & Johnson, and Novavax.’

A quite possibly wonderful summer

‘The summer of 2021 is shaping up to be historic... After months of soaring deaths and infections, COVID-19 cases across the United States are declining even more sharply than experts anticipated. This is expected to continue, and rates of serious illness and death will plummet even faster than cases, as high-risk populations are vaccinated. Even academics who have spent the pandemic delivering ominous warnings have shifted their tone to cautiously optimistic now that vaccination rates are exploding.’

Malaysia enforces requirement for improved worker lodging to rein in Covid-19

‘Malaysia has gazetted an emergency ordinance compelling employers to provide lodging with sufficient living space and amenities for migrant workers to effectively control the spread of Covid-19, the Human Resources Ministry said on Thursday (Feb 18).

‘It is among the first emergency ordinances - laws that do not require prior parliamentary approval - to be enforced since a national emergency was declared on Jan 12 to curb the coronavirus spread.

‘Covid-19 infections in Malaysia have raged among migrant workers who typically work and live closely, with an outbreak at world's largest glove maker Top Glove becoming the largest cluster in the country in December after more than 5,000 workers were infected.’

Inside poverty: How we gave a voice to Asia’s poor during Covid-19

‘When COVID-19 struck in 2020, sending many Asian countries into lockdown, CNA’s Insight series zoomed in on its impact on the poor - with teams on the ground in Indonesia, Malaysia, the Philippines, Bangladesh, India and Hong Kong. Poverty rates soared for the first time in almost two decades, dealing a blow to decades worth of poverty alleviation efforts.

‘With well over 100,000 views per episode, Poverty in Asia drew thousands of comments, ranging from words of encouragement for our profiles, to asking questions such as “is this poverty porn?” and “Why do the poor have so many children?”.

‘The producers behind the episodes, Aji Yahurti from Indonesia, Chen Yih Wen from Malaysia, Lolita Lachia from Philippines and Insight’s Ikhwan Adrian Rivai answer viewers’ questions and talk the about the challenges faced in recording the stories of the poor, amid a pandemic.

‘They also share about unexpected kindnesses and life lessons they learnt from those living in scarcity. One profile from the Philippines, Tricia Borromeo, had received $2,000 in donations to resume her university education, after the episode was released.’

No jab, no job? Ethical issues in mandatory Covid-19 vaccination of healthcare personnel

‘Mandating COVID-19 vaccination of healthcare personnel (HCP) could maximise vaccine uptake, but risks exacerbating breakdowns in trust between HCP and their institutions.

‘Ethical arguments for mandating COVID-19 vaccination of HCP appeal to their duties to ‘do no harm’ and to care for patients, but the fulfilment of these duties requires a safe working environment.

‘We argue for policies aimed at strengthening HCP’s trust in healthcare systems by addressing HCP concerns, including the institutional factors that have put them at risk of infection throughout the COVID-19 pandemic, before considering a COVID-19 vaccine mandate.’

Malaysia’s National Covid-19 Immunisation Plan: The missing details — Ezzaty Hasbullah

‘The Malaysian Government has recently published its National Covid-19 Immunisation Programme (NIP) outlining its strategy to achieve coverage by February of 2022. Though the document gives a good overview of the country’s vaccination plan from procurement to vaccination, it omits the minute execution details on several aspects along this value chain. The missing details:

  • Trust building and outreach
  • Ensuring equity in access
  • Task-shifting and training
  • Strengthening digital infrastructure

‘What the NIP gives is a general overview of the immunisation efforts in the months to come. What it does not give are the particulars in each step towards achieving this goal. More information on the actual particulars in realising this strategy has to be made available for public scrutiny — if such particulars are even available. These details could be the differentiating factors in determining Malaysia’s success or failure to achieve its 2022 immunisation targets because, as always, the devil is in the details.’

How much testing is enough? It’s complicated

‘One of the key measures of a country’s Covid-19 response is how much testing is done. The more cases in the community, the greater the need to expand testing to keep pace with the outbreak. But just how much testing is enough?

‘At a press conference on Tuesday, Health Ministry director-general Dr Noor Hisham Abdullah said the benchmark set by the World Health Organisation (WHO) is to have at least ten negative tests for every person found to be positive. In other words, the test positivity rate should be no higher than about 10 percent. Any higher, it suggests many cases are being missed.

‘However, several sources including health experts quoted in previous Malaysiakini reports had instead cited a five percent figure as the benchmark to meet. One source, the website "Our World in Data", even cited WHO for setting it as the benchmark. So, who is right? And how did different sources attribute different numbers to WHO?’

Vaccine hesitancy: Israel's much-publicised vaccination drive hits stumbling blocks

‘Prime Minister Benjamin Nethanyahu, who's made the vaccination campaign a major election issue, warned that more than half a million Israelis over the age of 50 have still not gone to get their jab. "I remind you of the most dramatic piece of data," he said this week. "97% of deaths and 93% of severe cases are in this group." Since the start of the pandemic over 5,400 people have died of COVID-19.

‘Overall, four million Israelis have been vaccinated so far, and about 2,6 million of them have received both shots. Since February, everybody aged over 16 has been called upon to get their shot. "We are trying to see what are the attitudes of people towards the vaccine. There is a tremendous amount of fake news in the public," says Dr. Boaz Lev, head of the vaccine task force at the Ministry of Health in Jerusalem. "This is worrisome, but it will take a while to know what the compliance is."

Covid-19 cases are dropping fast. Why?

‘One month ago, the CDC published the results of more than 20 pandemic forecasting models. Most projected that COVID-19 cases would continue to grow through February, or at least plateau. Instead, COVID-19 is in retreat in America. New daily cases have plunged, and hospitalizations are down almost 50 percent in the past month. This is not an artifact of infrequent testing, since the share of regional daily tests that are coming back positive has declined even more than the number of cases. Some pandemic statistics are foggy, but the current decline of COVID-19 is crystal clear.

**Four reasons: social distancing, seasonality, seroprevalence, and shots.’

The coronavirus is here to stay — here’s what that means

‘In January, Nature asked more than 100 immunologists, infectious-disease researchers and virologists working on the coronavirus whether it could be eradicated. Almost 90% of respondents think that the coronavirus will become endemic — meaning that it will continue to circulate in pockets of the global population for years to come (see 'Endemic future')...

‘More than one-third of the respondents to Nature’s survey thought that it would be possible to eliminate SARS-CoV-2 from some regions while it continued to circulate in others. In zero-COVID regions there would be a continual risk of disease outbreaks, but they could be quenched quickly by herd immunity if most people had been vaccinated.’

FLCCC to Merck: The data shows ivermectin's strong efficacy against Covid-19

‘The Front Line COVID-19 Critical Care Alliance (FLCCC) has issued a public statement in response to a press release recently issued by Merck.

‘The FLCCC Alliance reports that the Merck release of February 4, 2021— which concluded that there was no meaningful evidence for the clinical efficacy of ivermectin in patients with COVID-19 disease — did not provide any scientific data or analyses by Merck to support their conclusion.

‘Dr. Pierre Kory, President and Chief Medical Officer of the FLCCC said that, "The company's disregard for the most current medical evidence is an evidentiary indictment of their uncorroborated position. Merck's press release will cause governments, health authorities, medical providers, business leaders, and citizens to retreat from pursuing a medical agent that, according to our recent peer-reviewed and accepted publication to the highly regarded Frontiers in Pharmacology, has been proven to be an effective and globally available agent to prevent and treat every phase of COVID-19 disease."

Trump’s false posts were treated with kid gloves by Facebook

‘In August, as the election approached and misinformation about COVID-19 spread, Facebook announced it would give new fact-checking labels to posts, including more nuanced options than simply “false.” But data from The Markup’s Citizen Browser project, which tracks a nationwide panel of Facebook users’ feeds, shows how unevenly those labels were applied: Posts were rarely called “false,” even when they contained debunked conspiracy theories. And posts by Donald Trump were treated with the less direct flags, even when they contained lies. The Markup shared the underlying data for this story with Facebook.’

The next pandemic? It may already be upon us

‘Antimicrobial resistance (AMR) won’t race across the world like Covid-19, but its effects will be devastating. Thankfully, we already know what we need to do to defeat it...

‘Reining in the inappropriate use of antibiotics, in humans and in farmed animals, is key to staying ahead of AMR, but we also need novel anti-infectives coming down the pipeline – new last resorts. The thing holding up that pipeline to date has been the same thing that meant we had no coronavirus vaccines at the start of this pandemic: the economic incentives are few. Because antibiotics tend to be needed in relatively small quantities at a time, there are no economies of scale to be had either.

‘That’s the bad news; now for the good. Efforts are afoot to stimulate the development of novel anti-infectives. Outterson is the founder and executive director of CARB-X, which is funded by the British and German governments, the Wellcome Trust, the Bill & Melinda Gates Foundation and several arms of the US government, and which promotes the early stages of R&D – technically, the preclinical and phase 1 clinical phases. Meanwhile, last July the International Federation of Pharmaceutical Manufacturers and Associations launched a $1bn initiative, the AMR Action Fund, to finance the much more expensive phase 2 and 3 clinical trials that bring a drug – the few that get that far – to the threshold of regulatory approval. And the UK is experimenting with a new subscription-style payment model that pays drug companies upfront for access to novel antibiotics, so decoupling profit from volume sold.’

Sensationalising, misrepresenting facts does disservice to people: Jeyakumar Devaraj

‘Yesterday morning, I came across an article titled “UK Government releases shocking report on Covid vaccine side effects” in one of the WhatsApp chat groups I am in. This article by dailyexpose.co.uk, dated 9 February 2021, states that 70,500 adverse reactions were reported in the 6.9 million people vaccinated in the UK between 8 December 2020 and 24 January 2021.

‘The article says five people went blind, 21 suffered strokes, 69 developed facial nerve weakness (Bell’s Palsy) and 107 died because of the Covid vaccine they received.

‘This is a terribly unscientific way of looking at the data. People get sick, suffer various maladies and die even when not vaccinated. So, we need to check whether the incidence of each of these adverse events is actually higher in the vaccinated cohort when compared to the baseline figures for that population. If it is, then it could be possible that the vaccine predisposes to these conditions, and we would have to look more closely.

‘Let’s take the deaths first. According to the UK Office for National Registration, in 2019 there were 1,079.4 deaths per 100,000 males and 798.9 deaths per 100,000 females – over the whole year.

‘The 107 deaths observed in the 6.9 million vaccinated individuals gives a mortality rate of 1.6 per 100,000 – over seven weeks. If we annualise it by multiplying 1.6 by 52 and dividing it by 7, we arrive at a figure of 11.5 per 100,000 – much lower than the UK Crude Death Rate (CDR) for 2019 (CDR = overall death rate without breaking it down into death rates for each age group). These figures indicate that it would be difficult to sustain an argument that the Covid vaccine increases the risk of dying in the UK population.’

Coronavirus: Is the pandemic finally coming to an end in India?

‘By the middle of last week, India was barely counting an average of 10,000 Covid cases every day. The seven-day rolling average of daily deaths from the disease slid to below 100. More than half of India's states were not reporting any Covid deaths. On Tuesday, Delhi, once an infection hotspot, did not record a single Covid death, for the first time in 10 months.

‘So far, India has recorded more than 10 million infections - the second-highest in the world after the US. There have been over 150,000 reported deaths from the disease. The number of deaths per million people stands at 112, much lower than what has been reported in Europe or North America. It is also clear that the decline in cases is not because of lower testing.

‘Most pandemics typically rise and fall in a bell-shaped curve. India has been no exception. Also, it has seen a high proportion of cases and deaths of people above the age of 65 living in densely packed cities, hewing to infection trends around the world. "There's nothing unusual about infections dropping in India. There's no miracle here," says Dr Shahid Jameel, a leading virologist. Experts say there's no dearth of possible causes - explained below - for the relatively low severity of the disease and its toll.’

Anatomy of a conspiracy: With Covid, China took leading role

‘From Beijing and Washington to Moscow and Tehran, political leaders and allied media effectively functioned as superspreaders, using their stature to amplify politically expedient conspiracies already in circulation. But it was China -- not Russia – that took the lead in spreading foreign disinformation about COVID-19’s origins, as it came under attack for its early handling of the outbreak.

‘A nine-month Associated Press investigation of state-sponsored disinformation conducted in collaboration with the Atlantic Council’s Digital Forensic Research Lab, shows how a rumor that the U.S. created the virus that causes COVID-19 was weaponized by the Chinese government, spreading from the dark corners of the Internet to millions across the globe. The analysis was based on a review of millions of social media postings and articles on Twitter, Facebook, VK, Weibo, WeChat, YouTube, Telegram and other platforms.’

On WHO trip, China refused to hand over important data

‘Chinese scientists refused to share raw data that might bring the world closer to understanding the origins of the coronavirus pandemic, independent investigators for the World Health Organization said Friday.

‘The investigators, who recently returned from a fact-finding trip to the Chinese city of Wuhan, said disagreements over patient records and other issues were so tense that they sometimes erupted into shouts among the typically mild-mannered scientists on both sides.

‘China’s continued resistance to revealing information about the early days of the coronavirus outbreak, the scientists say, makes it difficult for them to uncover important clues that could help stop future outbreaks of such dangerous diseases.

“If you are data focused, and if you are a professional,” said Thea Kølsen Fischer, a Danish epidemiologist on the team, then obtaining data is “like for a clinical doctor looking at the patient and seeing them by your own eyes.”

‘For 27 days in January and February, the team of 14 experts for the WHO led the mission to trace the origins of the pandemic. Several say their Chinese counterparts were frustrated by the team’s persistent questioning and demands for data.’

The ‘saviour’ loan apps that trapped pandemic-struck Indians

‘The apps proliferated as the pandemic and the lockdown left millions in India jobless. While many working class jobs have returned, salaried professionals - from engineers and software developers to salesmen - and small businesses have struggled to survive. So the apps helped them out when they needed money quickly.

‘For loans as small as $150 and for periods as short as 15 days, these apps charge a one-time processing fee, a convenience fee and steep interest rates - some as high as 30%. Compare this to to Indian banks, which lend at 10-20% with a tenure of at least 12 months.

‘Like many other apps, at the time of download, these apps too ask for permission to access contacts and photo galleries. When an unsuspecting borrower agrees to this, they become more vulnerable.

"When I investigated one such case, I found that these apps are actually not only able to read and access your contact list, they're also capturing your images, videos and location. They also know many things about you - like, where you have actually used this money, to whom you have transferred this money," says cyber security expert Amit Dubey.’

The pandemic has unmasked America’s deepest inequities: Covid’s disparate racial impacts, by the numbers

‘Covid-19 doesn’t discriminate, but the havoc wrought by the virus—the deaths, economic devastation, and intergenerational trauma—has disproportionately affected Black, Latino, and Native American communities. The Trump administration’s feckless response didn’t help, yet even proactive steps have reinforced preexisting inequities: Stay-at-home orders protected people with the privilege to work remotely while frontline workers, disproportionately Black and Latino, took on greater risk of exposure. People of color have also experienced more unemployment and financial insecurity. As Mary Bassett, director of Harvard’s François-Xavier Bagnoud Center for Health and Human Rights, explains, none of this is caused by the virus itself: “It’s because of the social consequences of race in our society, which has been reinforced by decades, centuries of bad practices and policies.”

Khairy: Non-citizens to receive free Covid-19 vaccines to ensure everyone is safe

‘Malaysia will only be safe from the Covid-19 pandemic if the people, including foreign citizens living here, receive the vaccines, said Science, Technology and Innovation Minister Khairy Jamaluddin. He said that even if Malaysians were to receive the vaccines, it would not mean they are safe because Malaysia has about three million foreigners who are likely to cause the virus to spread and infect Malaysians.

“That is why this (giving free vaccines to non-citizens) needs to be done because we are not safe until everyone is safe. In vaccine science, if there are more vaccine recipients, then we are safe and the virus cannot infect others. As such, we are targeting 80 per cent of the population to create group immunity and form enough antibodies so that the virus does not infect people in the country. If we (locals) are the only recipients, we will not be safe because they (foreigners) may still infect us, or the virus could spread among the foreigners. That is why it is important that we protect everyone. This is the right decision for the sake of humanity,” he said.’

How to manage vaccine liability in Malaysia

‘While different systems vary in terms of elements of compensation and funding mechanisms, we can adapt the policies related to funding, proving injury and distributing compensation involving multiple parties. For example, we can set up a bespoke Covid-19 vaccine compensation programme. The programme could be co-financed by a mixture of public and private funds (eg. led by insurers), to achieve effective immunisation roll-out while providing a fair and equitable remedy and reduce overall costs to society.  

‘Two, Malaysia’s government can adapt the Singapore model and completely assume the financial costs of any serious adverse events from the vaccine. The list of serious adverse events that are covered, the mechanism of approval and the ministry which will pay are details that can be decided by a relevant committee. Given serious adverse events are rare, the overall cost should be manageable and represents a good investment for public confidence.

‘A third option is the Covax Facility’s no-fault-compensation scheme for indemnification and liability. The scheme proposed by Covax aims to set up a compensation fund for vaccine recipients in participating countries who might suffer any side-effects from COVID-19 vaccines. The scheme proposes a new mechanism to pay a lump-sum based on severity of harm to victims from Covid-19 vaccines associated side effects. The proposed mechanism would be funded by earmarking funds from high income countries or by charging taxes on pharmaceutical companies.  

‘There are reasonable solutions to the problem, and Malaysia must have a full-frontal and honest conversation about how to manage adverse events, no matter how unlikely they might be. All the solutions described above are not mutually exclusive. However, implementing them requires political will and courage. Covid-19 vaccination is a collective national effort, and we must do all we can to increase public confidence in the vaccine by providing appropriate liability protections.’

Why it’s so hard to make antiviral drugs for Covid and other diseases

‘Antibiotics abound, but virus-fighting drugs are harder to come by. Fortunately, scientists are getting better at making and finding them...

‘The pandemic has sent scientists scrambling to find treatments. Heise [virologist Mark Heise of the University of North Carolina at Chapel Hill], for one, is testing a wide range of drugs—not just standard antivirals—against SARS-CoV-2 in lab dishes, as part of the Rapidly Emerging Antiviral Drug Discovery Initiative (READDI). The idea is that, because the virus depends on many processes in human cells, a variety of medications that act on human proteins might give doctors an edge by hurting the virus more than the patient. That throws the doors open to considering medications that were originally designed for cancer, psychosis, inflammatory conditions and autoimmune disease, to see if they might have a shot against Covid-19.

‘But the READDI collaborators—including academic centers, pharmaceutical companies and nongovernmental organizations—are aiming for more than a Covid-19 treatment. READDI hopes to identify and test potential medications for as-yet-unknown infections that may crop up in the future.

‘By getting early human safety testing done ahead of time, they’ll be ready to spring into action when those future outbreaks happen. As Heise says, “We don’t want to repeat what we’ve just been through.”

Online scammers are rushing to exploit people desperate to get the Covid-19 vaccine

‘Many Americans are eager to get the Covid-19 vaccine as quickly as possible. But that inevitably means there are scammers ready to use the internet to take advantage of these vaccine seekers to steal their money and personal information.

‘Similar to earlier in the pandemic, when fraudsters flooded the internet with ads for sketchy “cures,” bogus Covid-19 tests, and scarce personal protective equipment, online schemers are now selling fake vaccine appointments and knockoff vaccine cards. (These cards document the date that vaccinated people received their doses, the manufacturer of their vaccine, and its batch number; they’re seen as a record of vaccination.)

‘Vaccine schemes are alarming. In late January, one man in Washington state was arrested after advertising fake Covid-19 vaccines online for as much as $1,000, and even injected people with an unknown substance, according to the Department of Justice, which is investigating these types of fraud cases.’

‘Pure, liquid hope’: What the vaccine means to me as a GP

‘Clinicians everywhere are all nervous about what will happen if that loosening of restrictions occurs too quickly. Though death from Covid among the under-50s is relatively rare, it can still be a terrible, terrifying disease, capable of rendering its victims breathless and exhausted for weeks (and in some cases, months) after its fevers have run their course. One of my own patients, a nurse in his 20s, used to run 10km three or four times a week. The staff vaccination programme was too late for him: he caught Covid on the wards just before Christmas. Though he’s now back at work, he still hasn’t recovered sufficiently to be able to get back to running.

‘For the next six months, all my colleagues and I will be vaccinating as needed, as many hours as we’re able to. This week I’ve been gladly trudging the streets in the snow, vaccinating our housebound patients, and there aren’t too many still to go. In Scotland, the programme is anticipated to go on at least until 31 July, and the hope is that everyone over 50 will have had a first dose by May.

‘The numbers are daunting, but there’s a spirit of anticipation and celebration in the air. Many are starting to dare to plan for a world post-Covid, and I’m tempted to share that optimism. Opening my first box of vials, I thought of a friend in Orkney, a GP who’d already vaccinated all the over-80s of his practice, and who’d begun to call in the over-70s. We met briefly in Kirkwall, outdoors, on my journey from Orkney back to Edinburgh. “How did it feel to get started?” I asked him.

“I almost wept as I opened that box of vials,” he said, smiling at the memory. “Each one was hope – pure, liquid hope.”

Immunitee Malaysia's first health passport accepted in Singapore

‘Malaysia’s Immunitee Health Passport has partnered with Temasek-founded Affinidi to become the country’s first health passport to be accepted in Singapore, via Affinidi’s Unifier digital credential platform.

‘The Immunitee Health Passport is a system designed to store personal immunisation records and vaccine data, which helps to facilitate users’ clearance at border health checkpoints, ensure data protection and security through blockchain, and verify the authenticity of Covid-19 tests and vaccines.

‘In a statement today, Immunitee said the Unifier platform provided interoperability, enabling the secure sharing of necessary data with the various national health check systems being put in place globally.’

Ground SOPs in science: The Academy of Medicine of Malaysia

‘The Academy of Medicine of Malaysia is troubled by the introduction of the Prevention and Control of Infectious Diseases (Exemption) Order 2021, which states that Cabinet ministers returning from official overseas visits must only quarantine for 3 days instead of the mandatory 10 days for inbound travellers. The Health Minister clarified that only Cabinet ministers who travel in a ‘bubble itinerary’ will undergo 3-day quarantine. Moreover, this move is intended to open up the economy as the policy will eventually be applicable to foreign dignitaries and business travellers.

‘We, the Academy of Medicine of Malaysia, wholeheartedly oppose the Exemption Order as well as any plans to extend the 3-day quarantine rule to other travellers.

‘We wish to remind the government that all standard operating procedures (SOP) must be grounded in science. The quarantine period for inbound travellers is set at 10 days based on research which shows that the risk of transmission is extremely low (~1%) after 10 days with monitoring and testing in place. The incubation period for Covid-19 is on average 5 to 6 days but can be as long as 14 days. Therefore, three days is insufficient to detect symptoms. There must be an evidence-based, public health explanation for the government’s decision to reduce quarantine days.

‘The effectiveness of so-called ‘travel bubbles’ are also still in question as new variants of Covid-19 with increased transmission capability spread rapidly around the world. There is insufficient data on the mutations to develop robust protocols for safe travel. We understand there is urgency to restart the economy for the benefit of Malaysians and businesses that are struggling, but this can only be done by bringing the pandemic under control first. The government must not open up our borders to ‘bubble’ delegations and risk bringing in new variants that could overwhelm our health system.

‘We call on the government to revoke the Exemption Order and—until there is scientific evidence that suggests differently—enforce a 10-day quarantine for all.’

Common asthma drug cuts Covid-19 hospitalisation risk, recovery time: Oxford study

‘A commonly used asthma treatment appears to reduce the need for hospitalisations as well as recovery time for COVID-19 patients if given within seven days of symptoms appearing, researchers at the University of Oxford said on Tuesday (Feb 9).

‘The findings were made following a mid-stage study of the steroid budesonide, sold as Pulmicort by AstraZeneca and also used for treating smoker's lung.

‘The 28-day study of 146 patients suggested that inhaled budesonide reduced the risk of urgent care or hospitalisation by 90 per cent when compared with usual care, Oxford University said.’

What Covid-19 has done to our well-being, in 12 charts

‘How has Covid-19 and the related shift to WFH affected workers? A group of researchers surveyed HBR readers and others in the fall of 2020 and found that the vast majority reported declines in both general and workplace well-being. The biggest culprits? Mental health struggles, increased job demands, and home-life challenges. A much smaller percentage reported an increase in well-being, attributing it to reduced commutes and business travel and having more time to focus on health.’

Trust in Covid vaccines is growing

‘Attitudes towards COVID-19 vaccines seem to be improving in some parts of the world, a survey of thousands of people in 15 countries has found. Researchers have welcomed the results, which suggest that an increasing proportion of people are willing to be immunized. But they caution that some problems persist, such as concerns about vaccine safety. “For the first time since the pandemic began, I can sense that optimism is spreading faster than the virus,” says behavioural scientist Sarah Jones at Imperial College London, who co-led the global attitudes towards a COVID-19 vaccine survey.

‘The survey is part of the COVID-19 behaviour tracker, run by Imperial together with the UK market-research company YouGov.’

Rebuilding a better, post-Covid-19 world with a new mindset of stakeholders: WEF founder Klaus Schwab

‘World War II was a time of great crisis and hardship, which forged a sense of solidarity that helped pull ravaged communities together. "To a certain extent, we are in a similar situation today...we went through a major crisis, which affected everybody in the world," says the founder and executive chairman of the World Economic Forum (WEF).

‘He is also here for the launch of his new book, Stakeholder Capitalism: A Global Economy That Works For Progress, People And Planet, which he has written with a WEF colleague, Mr Peter Vanham...

‘Indeed the stakeholder concept has featured prominently in his work since the 1973 Davos Manifesto, which set out the role of business managements to "serve clients, shareholders, workers and employees, as well as societies, and to harmonise the different interests of the stakeholders".

‘It is a theme he delves into deeper in his new book. "The idea that we need to rebuild differently post-Covid is widely shared. The sudden and all-encompassing impact of Covid-19 made us understand, much more than the gradual effects of climate change or increasing inequality, that an economic system driven by selfish and short-term interests is not sustainable...’

Nonstimulus arithmetic: Why the American Rescue Plan has to be big -- Krugman

‘We are not in a conventional recession — a decline in output due to insufficient aggregate demand. What we’re suffering from, instead, is a partial lockdown, the result of both public policy and private choices, that has sharply curtailed high-infection-risk activities, like indoor dining.

‘Pumping up overall spending with fiscal and monetary policy wouldn’t send diners back into restaurants, nor should it. So we aren’t experiencing a normal output gap, something that should be closed by stimulus. It’s actually not clear whether we even want employment and GDP to be higher before vaccination gives us herd immunity.

‘What, then, is the role of policy? As some of us have been arguing all along, it’s not stimulus, it’s disaster relief: an attempt to shore up the living standards of those hurt by the temporary lockdown, as well as providing resources to deal with the pandemic itself. Or as I recently argued, you can think of what we’re doing as being something like fighting a war — special expenditure in the face of an emergency.’

Bhutan: The unlikeliest pandemic success story

‘On January 7, a 34-year-old man who had been admitted to a hospital in Bhutan’s capital, Thimphu, with preexisting liver and kidney problems died of COVID-19. His was the country’s first death from the coronavirus. Not the first death that day, that week, or that month: the very first coronavirus death since the pandemic began.

‘How is this possible? Since the novel coronavirus was first identified more than a year ago, health systems in rich and poor countries have approached collapse, economies worldwide have been devastated, millions of lives have been lost. How has Bhutan—a tiny, poor nation best known for its guiding policy of Gross National Happiness, which balances economic development with environmental conservation and cultural values—managed such a feat? And what can we in the United States, which has so tragically mismanaged the crisis, learn from its success?’

WHO team says theory Covid began in Wuhan lab ‘extremely unlikely’

‘The World Health Organization team that visited Wuhan to investigate the origins of the coronavirus pandemic has all but dismissed a theory that the virus leaked from a laboratory, while giving some credence to China’s focus on the possibility of transmission via frozen food.

‘They said the team’s work did not dramatically change the picture they had before they began, but had added important details to the story. The team found no evidence of widespread circulation of the virus in Wuhan prior to December 2019, and said it was still unclear how it got into the Huanan seafood market, where the virus was initially detected. But, they added, “all the work that has been done on the virus and trying to identify its origin continue to point toward a natural reservoir”.’

Prevalence and outcomes of SARS-CoV-2 infection among migrant workers in Singapore

‘There were 43 dormitories housing 198 320 migrant workers with a median occupancy of 3578 (interquartile range, 1458-6120); 99.8% of residents were male, with a median age of 33 years (interquartile range, 28-39 years). As of July 25, 95.1% of all residents had at least 1 SARS-CoV-2 test, including 63.6% with PCR and 68.4% with serology. There were 111 280 residents with a positive PCR or serology result, for an overall infection prevalence of 56.1% (95% CI, 55.9%-56.3%) (range per dormitory, 0%-74.7%; median, 52.9%). 

‘There were 24 197 clinical cases (12.2% of all residents; 21.7% of infected) from 42 dormitories and 87 083 subclinical cases (43.9% of all residents; 78.3% of all infected) (Table). Of all clinical cases, 20 cases required ICU admission (0.08% [95% CI, 0.05%-0.13%]), with 1 COVID-19 attributable death (case-fatality rate, 0.004% [95% CI, 0.0002%-0.027%]).’

Safely reopening requires testing, tracing and isolation, not just vaccines

‘The Moderna and Pfizer vaccines were developed in record time. However, these announcements highlight significant challenges: delivering two-dose vaccines with stringent cold-chain requirements to almost eight billion people, many of whom reside in communities with underfunded and strained health systems, is no small feat. Even if we address the logistical challenges, the reality is that it takes time and funding to deliver vaccines, treatments and tests that reach everyone in need. It is a sobering reminder that when lifesaving antiretrovirals were introduced for HIV-positive people, it took seven years before the medicine reached the poorest communities. And during that time, millions of people died, and millions more were infected, and the HIV pandemic continued to grow.

‘Until we can overcome these obstacles and ensure equitable delivery of vaccines and treatments once available across the globe, the fundamentals of controlling this virus remain as important as ever.

‘For a long time, many countries will continue to rely on already proven tools to control the pandemic. The formula is simple: test, trace and isolate. This straightforward but effective process is key to safely reopening economies and societies. It is made possible through the rapid and equitable scale-up of diagnostics, which have proven to be the most important tool for limiting the spread of COVID-19. Test, trace and isolate—and ultimately test, trace and treat once more treatments become available—is an efficient, sustainable way to control the virus, especially in contrast to last-resort emergency lockdown measures, which can erode the public support and trust necessary for the success of many other helpful public health measures, including vaccination and mask-wearing.

‘We have seen this strategy implemented successfully around the world for decades with age-old diseases like tuberculosis. This strategy is also making a difference in the fight against COVID-19.’

Protein behind corona’s slow Asia spread: Study

‘Deficiency in a particular human protein, which is more common in Europe and the United States than in Asia, could explain why coronavirus is not spreading as fast in Asian countries. A team of scientists from the National Institute of Biomedical Genomics in Kalyani, West Bengal, have found a biological reason for the slower spread of a mutant of coronavirus in Asia compared to the West. The team has explained how higher levels of a human protein — neutrophil elastase — helps the virus to enter the human cell, multiply and also spread faster from infected individuals... 

“However, some naturally-occurring mutations in the AAT-producing gene results in deficiency of the AAT protein. This deficiency is known to be much higher in the Caucasians of Europe and America than among Asians,” said Majumder. “While we used AAT deficiency data from East Asia, along with North America and Europe, for the study, considering the pace at which the coronavirus is spreading, the numbers are representative of other Asian regions too, including India.”... 

‘As per their data, AAT deficiency is the least in East Asian countries — 8 per 1,000 individuals in Malaysia, 5.4 per 1,000 in South Korea, 2.5 in Singapore. On the other hand, 67.3 in per 1,000 individuals in Spain are AAT deficient, 34.6 in the UK and 51.9 in France and in the US it is prevalent in 29 individuals among 1,000.’

Tribal health providers have figured out the key to Covid-19 vaccine success. Here's their secret

‘It's important to note that there are 574 federally recognized tribes, making it difficult to broadly characterize how the vaccine rollout is going across Indian Country. Native people get their health care from a patchwork system of Indian Health Service facilities, tribally-operated clinics and urban Indian health centers, and vaccination efforts have varied from tribe to tribe and state to state.

Still, the successes of some tribal health providers offer lessons for communities struggling to vaccinate their populations efficiently. Here are some of them.

  • They tailored their messaging to build trust
  • They have the autonomy to decide who gets priority
  • This health system is owned by its people
  • They made big investments in health care
  • Ultimately, success depends on the nation's vaccine supply

Covid lockdowns in Hong Kong: Ambush-style action clearly works

‘The ambush-style lockdowns in Hong Kong are being criticised as a violation of human rights. However, such sudden lockdowns may remain the most efficient way for the city to control the spread of Covid-19 (“Hong Kong’s latest lockdowns uncover four Covid-19 cases in three buildings”, February 8).

‘To know the reason for this, we must know the answer to two questions: why a lockdown, and why ambush-style... (1) Lockdowns are the most effective way known for tracing or eliminating the virus infection chain... (2) As for the ambush style adopted, the lack of notice is the only way to ensure that no one can escape the lockdown...’

Travelling during Covid: ‘I was nervous using a fake Covid-19 test certificate’

‘Coronavirus has changed the way we travel and many countries now demand proof of a negative Covid test before letting you in - with tests often costing hundreds of pounds. BBC reporter Joice Etutu has been speaking to two women who admit using and selling fake certificates...

‘Jessica* is also 24. She admits to selling fake Covid-19 certificates to people who wanted to travel abroad by advertising her services on social media. She says it was "easy money". "They just didn't want to pay £150 for a private test," she says. "We charged them £50. "Because it was so cheap people were asking so many questions, like 'how does it work?', 'when I get to the place are they gonna double check?', 'how did you do it?', 'am I gonna get in trouble?'"

‘Buying or even attempting to buy a forged certificate is a crime in the UK and using a forged certificate to travel is fraud by false representation. If you're caught selling fake certificates in the UK, you might face a prison sentence. Currently, it's the responsibility of airlines to check that passengers have a negative test result.’
