Covid has become a disease of the unvaccinated

Covid has become a disease of the unvaccinated

Nature reports: On 21 June, Israel’s Ministry of Health recommended that all individuals aged 12–15 be vaccinated against COVID-19 — making the nation one of the few that have so far approved vaccinations for younger adolescents. The decision came in response to a trend that many countries with high rates of vaccination are experiencing: an ever-increasing proportion of new infections are in younger age groups. Israel’s swift vaccination campaign — which has now reached more than 85% of the adult…

Delta variant said to be far more widespread than federal estimates

Delta variant said to be far more widespread than federal estimates

Politico reports: The more-transmissible Delta coronavirus variant is believed to be significantly more widespread than the current federal projections, according to two senior Biden administration health officials with knowledge of the situation. Centers for Disease Control and Prevention data released late Tuesday shows the Delta strain accounted for more than 51 percent of new Covid-19 cases from June 20 to July 3. But the reality on the ground is likely much higher because states and private labs are taking weeks…

Global experts urge Boris Johnson to delay ‘dangerous’ Covid reopening

Global experts urge Boris Johnson to delay ‘dangerous’ Covid reopening

The Guardian reports: Lifting the remaining Covid restrictions in England this month is “dangerous and premature”, according to international scientists and doctors, who have called on the UK government to pause reopening until more people are vaccinated. Writing in the Lancet, more than 100 global experts warn that removing restrictions on 19 July will cause millions of infections and risk creating a generation with chronic health problems and disability from long Covid, the impact of which may be felt for…

Covid origins mirror SARS’s genesis in animals, study finds

Covid origins mirror SARS’s genesis in animals, study finds

Bloomberg reports: Early Covid-19 cases traced to markets in Wuhan, China, mirror the initial spread of SARS 17 years earlier, scientists said in a paper that concludes that an animal contagion is the most likely explanation for the pandemic’s genesis. The epidemiological history of SARS-CoV-2 is comparable to previous animal market-associated outbreaks of coronaviruses and offers a simple route for human exposure, Edward Holmes, Andrew Rambaut and 19 other researchers said Wednesday in a review of the scientific evidence pertaining…

‘Social’ mitochondria, communicating between cells, influence health

‘Social’ mitochondria, communicating between cells, influence health

Katarina Zimmer writes: During his doctoral research on the ties between aging and mitochondria, Martin Picard frequently saw micrographs of those energy-producing organelles. Yet it wasn’t until fairly late in his graduate work that he first watched sped-up video of mitochondria moving inside live human cells, and the sight came as a revelation. Tagged with fluorescent dye, the mitochondria were neon squiggles crawling through the soupy interior of the cells — stretching and contracting, fusing together and splitting up again,…

Surging global food prices put staple meals out of reach

Surging global food prices put staple meals out of reach

The Washington Post reports: A year of coronavirus pandemic saw a pot of jollof rice grow steadily more expensive in the Nigerian suburb of Nyanya. At Nyanya Market, near Abuja, Nigeria’s capital, the price of the rice that forms the base for the dish went up by 10 percent. A small tin of tomatoes? Twenty-nine percent costlier. And the onions? Their price jumped by a third, according to a Nigerian research firm. Surging consumer food prices are a local problem…

Birthday parties as virus vector

Birthday parties as virus vector

Margot Sanger-Katz writes: At the height of the pandemic, it was easy to worry that strangers would give you the virus. But a new study of what happened after people’s birthdays suggests that people we trust were also a common source of viral spread. Private gatherings have been harder for researchers to measure than big public events — they’re private, after all. And there has been a fierce debate for months among epidemiologists about just how big a factor they…

The divide between vaccinated and unvaccinated America

The divide between vaccinated and unvaccinated America

Sarah Zhang writes: Last winter, when vaccines were still incredibly scarce in the United States, Ashish Jha told The Atlantic that he was feeling optimistic about summer: By July 4, Jha, the dean of the Brown University School of Public Health, expected enough people to be vaccinated that he could host a backyard barbecue. Indeed, Jha confirmed to me this week, he will be grilling burgers and hot dogs for friends this Fourth of July. He had predicted back in…

Calls grow for an investigation into FDA approval of Biogen’s Alzheimer’s drug

Calls grow for an investigation into FDA approval of Biogen’s Alzheimer’s drug

STAT reports: Former health secretary Donna Shalala called for a federal investigation into the Food and Drug Administration’s polarizing approval of a Biogen treatment for Alzheimer’s disease, citing STAT’s revelation Tuesday that regulators were far more closely aligned with the company than previously disclosed. “When you see a report like this, you have to investigate it,” said Shalala, a former member of Congress who led the Department of Health and Human Services under President Clinton. “You cannot hesitate and you…

Inside the risky bat-virus engineering that links America to Wuhan

Inside the risky bat-virus engineering that links America to Wuhan

Rowan Jacobsen writes: In 2013, the American virologist Ralph Baric approached Zhengli Shi at a meeting. Baric was a top expert in coronaviruses, with hundreds of papers to his credit, and Shi, along with her team at the Wuhan Institute of Virology, had been discovering them by the fistful in bat caves. In one sample of bat guano, Shi had detected the genome of a new virus, called SHC014, that was one of the two closest relatives to the original…

A lack of coronavirus genomes could prolong the pandemic

A lack of coronavirus genomes could prolong the pandemic

Puja Changoiwala writes: Back at the beginning of the COVID-19 pandemic, before the disease had even drawn the attention of much of the world, researchers in China and Australia mapped the genome of the coronavirus isolated from one of the first patients in the Wuhan outbreak. This first genetic blueprint of the SARS-CoV-2 virus was publicly released soon after, on January 10, 2020. The disclosure of that genome, and others that soon followed, guided the vigorous international scientific response to…

How the drug industry has exploited reforms started in the fight against AIDS

How the drug industry has exploited reforms started in the fight against AIDS

Robert Bazell writes: Three decades ago, a small group from within the AIDS activist organization ACT UP changed the course of medicine in the United States. They employed what they called “the outside/inside strategy.” The activists staged large, noisy demonstrations outside the Food and Drug Administration and other federal government agencies, demanding an acceleration of the drug-approval process. Others learned the minutiae of the science and worked quietly with receptive bureaucrats, bringing the patient’s perspective to the table toward the…

Pfizer and Moderna vaccines likely to produce lasting immunity, study finds

Pfizer and Moderna vaccines likely to produce lasting immunity, study finds

The New York Times reports: The vaccines made by Pfizer-BioNTech and Moderna set off a persistent immune reaction in the body that may protect against the coronavirus for years, scientists reported on Monday. The findings add to growing evidence that most people immunized with the mRNA vaccines may not need boosters, so long as the virus and its variants do not evolve much beyond their current forms — which is not guaranteed. People who recovered from Covid-19 before being vaccinated…

Virologist Danielle Anderson paints a very different picture of the Wuhan Institute

Bloomberg reports: From her first visit before it formally opened in 2018, Anderson was impressed with the institute’s maximum biocontainment lab. The concrete, bunker-style building has the highest biosafety designation, and requires air, water and waste to be filtered and sterilized before it leaves the facility. There were strict protocols and requirements aimed at containing the pathogens being studied, Anderson said, and researchers underwent 45 hours of training to be certified to work independently in the lab. The induction process…

WHO urges fully vaccinated people to continue to wear masks as delta Covid variant spreads

WHO urges fully vaccinated people to continue to wear masks as delta Covid variant spreads

CNBC reports: The World Health Organization on Friday urged fully vaccinated people to continue to wear masks, social distance and practice other Covid-19 pandemic safety measures as the highly contagious delta variant spreads rapidly across the globe. “People cannot feel safe just because they had the two doses. They still need to protect themselves,” Dr. Mariangela Simao, WHO assistant director-general for access to medicines and health products, said during a news briefing from the agency’s Geneva headquarters. “Vaccine alone won’t…

Where did the coronavirus come from? What we already know is troubling

Where did the coronavirus come from? What we already know is troubling

Zeynep Tufekci writes: There were curious characteristics about the H1N1 influenza pandemic of 1977-78, which emerged from northeastern Asia and killed an estimated 700,000 people around the world. For one, it almost exclusively affected people in their mid-20s or younger. Scientists discovered another oddity that could explain the first: It was virtually identical to a strain that circulated in the 1950s. People born before that had immunity that protected them, and younger people didn’t. But how on earth had it…
