Omicron risks infecting vaccinated people but may not cause them severe illness

Omicron risks infecting vaccinated people but may not cause them severe illness

The Wall Street Journal reports: The Omicron variant of the Covid-19 virus could lead to more infections among vaccinated people, according to several scientists, but some said there were reasons to believe the shots would protect against severe disease. While the new variant might evade the antibodies generated in reaction to the vaccines, the virus will likely remain vulnerable to immune cells that destroy it once it enters the body, said Ugur Sahin, co-founder of BioNTech SE, which sells a…

It looks like Omicron causes milder illness – is this how COVID becomes endemic?

It looks like Omicron causes milder illness – is this how COVID becomes endemic?

AP Photo/Denis Farrell By Hamish McCallum, Griffith University These are very early days in terms of our understanding the Omicron variant. What is known is that it has a large number of mutations, particularly in the spike protein and it appears to be rapidly spreading in specific parts of the world. Very early indications from Africa suggest it does not cause particularly severe disease (though the World Health Organization has urged caution given the limited data available). At this point,…

How the Omicron variant rattled the world in one week

How the Omicron variant rattled the world in one week

The Wall Street Journal reports: Over coffee at his office on Tuesday, Tulio de Oliveira, director of South Africa’s Center for Epidemic Response and Innovation, let a colleague in on a secret. “There’s something going on,” he told Alex Sigal, a virologist growing coronaviruses at a South African laboratory. “They’ve found a variant they’ve never seen before.” For days, case numbers in the nation had been rising rapidly. Puzzled lab technicians had been getting back Covid-19 tests that were positive,…

WHO chief: Omicron backlash against Africa shows why world needs pandemic treaty

WHO chief: Omicron backlash against Africa shows why world needs pandemic treaty

Politico reports: It’s time for a new pandemic treaty, the chief of the World Health Organization said on Monday. The emergence of the new Omicron coronavirus variant amid vaccine inequity and the rapid imposition of travel bans on southern African nations “demonstrates just why the world needs a new accord on pandemics,” said WHO boss Tedros Adhanom Ghebreyesus, at a special session of the World Health Assembly. Countries are gathering at the session where they will agree to start negotiations…

Humans have evolved to stay active even in old age, new hypothesis claims

Humans have evolved to stay active even in old age, new hypothesis claims

Science Alert reports: In the modern western world, people tend to reduce their levels of physical activity as they get older. But with this inactivity comes a raft of adverse health effects, so why didn’t evolution engineer us so that people could maintain a decent quality of life as they inevitably slow down? In a newly published paper, researchers argue it is because we aren’t meant to reduce our physical activity as we age at all. Enter the ‘active grandparent…

How dangerous Omicron is, won’t be known for weeks

How dangerous Omicron is, won’t be known for weeks

Science reports: At 7.30 a.m. on Wednesday, Kristian Andersen, an infectious disease researcher at Scripps Research in San Diego, received a message on Slack: “This variant is completely insane.” Andrew Rambaut of the University of Edinburgh was reacting to a new SARS-CoV-2 genome sequence found in three samples collected in Botswana on 11 November and one picked up a week later in a traveler from South Africa to Hong Kong. Andersen looked at the data and then replied: “Holy shit—that…

Ten million deaths a year

Ten million deaths a year

David Wallace-Wells writes: Not​ all deaths are created equal. In February 2020, the world began to panic about the novel coronavirus, which killed 2714 people that month. This made the news. In the same month, around 800,000 people died from the effects of air pollution. That didn’t. Novelty counts for a lot. At the start of the pandemic, it was considered unseemly to make comparisons like these. But comparing the value of human lives is one thing the machine of…

How Norilsk, Siberia, became one of the most polluted places on Earth

How Norilsk, Siberia, became one of the most polluted places on Earth

Marianne Lavelle reports: It was 2 a.m. and the sun was shining, as it does day and night in mid-July in Norilsk, a Siberian city 200 miles north of the Arctic Circle. Igor Klyushin went to the bank of the river where he used to fish with his father for grayling, a sleek and dorsal-finned beauty known for its graceful leaps above the water surface. “A very merry fish,” Klyushin recalled. “It enjoys cold and clean, clean water.” He doubted…

What we need to understand about the Omicron variant

What we need to understand about the Omicron variant

Ashish Jha asks: How worrisome is Omicron? There are three key questions that help scientists understand how consequential any variant might be. The first question is whether the variant is more transmissible than the current, prevalent Delta strain? Second, does it cause more severe disease? And third, will it render our immune defenses — from vaccines and prior infections — less effective (a phenomenon known as immune escape)? On transmissibility, the data, while early, look worrisome. This new variant appears…

Western countries are destroying surplus doses of Covid vaccine while the poorest nations go without

Western countries are destroying surplus doses of Covid vaccine while the poorest nations go without

Gordon Brown writes: Despite the repeated warnings of health leaders, our failure to put vaccines into the arms of people in the developing world is now coming back to haunt us. We were forewarned – and yet here we are. In the absence of mass vaccination, Covid is not only spreading uninhibited among unprotected people but is mutating, with new variants emerging out of the poorest countries and now threatening to unleash themselves on even fully vaccinated people in the…

The West’s hoarding of vaccines set the stage for the Omicron variant to emerge

The West’s hoarding of vaccines set the stage for the Omicron variant to emerge

The New York Times reports: In poorer African nations, the cascade of travel closures triggered a wave of resentment among people who believed that the continent was yet again bearing the brunt of panicked policies from Western countries, which had failed to deliver vaccines and the resources needed to administer them. Richer countries, having already hoarded vaccines for much of 2021, were now penalizing parts of the world that they had starved of shots in the first place, scientists said….

Corruption: Biden’s FDA nominee returns with deeper Big Pharma ties

Bloomberg reports: President Joe Biden’s choice to lead the Food and Drug Administration made millions of dollars from health and drug companies since his last stint in government, raising new questions about his ties to firms the agency oversees. Robert Califf was paid $2.7 million by Verily Life Sciences, the biomedical research organization operated by Alphabet Inc., and sits on the boards of two pharmaceutical companies, AmyriAD and Centessa Pharmaceuticals PLC. He also reported ties to 16 other research organizations…

The only nation in the world where civilian guns outnumber people

The only nation in the world where civilian guns outnumber people

CNN reports: Atlanta. Orlando. Las Vegas. Newtown. Parkland. San Bernardino. Ubiquitous gun violence in the United States has left few places unscathed over the decades. Still, many Americans hold their right to bear arms, enshrined in the US Constitution, as sacrosanct. But critics of the Second Amendment say that right threatens another: The right to life. America’s relationship to gun ownership is unique, and its gun culture is a global outlier. As the tally of gun-related deaths continue to grow…

Americans need to be nudged out of the pandemic

Americans need to be nudged out of the pandemic

Juliette Kayyem writes: Perhaps you’ve figured this out already: The pandemic will not have a discrete end. The coronavirus will not raise a white flag. There will be no peace treaty, no parade, no announcement from the CDC that the United States is done worrying about COVID. You will not get closure. The signs remain too mixed. The virus continues to spread, even as widening vaccine eligibility, booster shots, and improved medical treatments limit the damage the virus can do….

How record wildfires are harming human health

How record wildfires are harming human health

Nature reports: On a cool September morning in San Francisco, a group of firefighters packed their gear into a bright red van. The sickly sweet odour of pine resin from a distant blaze hung in the air as the crew prepared to battle the rapidly growing Dixie fire, on its way towards becoming the largest single wildfire in California’s history. Sweeping across the Sierra Nevada mountains, it would come to scorch more than 3,900 square kilometres before crews fully contained…

A ‘universal’ flu vaccine could bring one of the world’s longest pandemics to an end

A ‘universal’ flu vaccine could bring one of the world’s longest pandemics to an end

Matthew Hutson writes: In 2009, global health officials started tracking a new kind of flu. It appeared first in Mexico, in March, and quickly infected thousands. Influenza tends to kill the very young and the very old, but this flu was different. It seemed to be severely affecting otherwise healthy young adults. American epidemiologists soon learned of cases in California, Texas, and Kansas. By the end of April, the virus had reached a high school in Queens, where a few…
