Data appears to support claims that Omicron is less severe in South Africa

Posted on by

Scientists warn, however, that lower severity of cases is not fully understood and may not occur elsewhere

South Africa has reported data on Covid cases driven by the Omicron variant that appears to give added impetus to claims the country is experiencing a lower severity of disease.

“In South Africa, this is the epidemiology: Omicron is behaving in a way that is less severe,” said Prof Cheryl Cohen of the country’s National Institute for Communicable Diseases (NICD), one of the authors of the study.

Covid: how has the pandemic changed in the UK in 2021?

The year has been marked by the success of the vaccination drive – yet thousands have still died

This time last year, Covid-19 cases were soaring in the UK, hospitalisations were steadily increasing, and the government had tightened restrictions to try to get a handle on a concerning new variant.

Twelve months on, there is a sense of deja vu. A weary public is worried about its festive plans being cancelled, an outcome that would be all the more painful in light of the Christmas party scandal that has enveloped Downing Street in recent weeks.

‘A moral issue to correct’: the long tail of Elena Ceaușescu’s fraudulent scientific work

Posted on by

Nicolae Ceaușescu’s Romanian communist regime hailed his wife as an eminent chemistry researcher, though she had no genuine qualifications. But her name lives on in academic journals, and British institutions have yet to retract honours bestowed on her

Romanian researchers have called on academic publishers to remove Elena Ceaușescu’s name from almost two dozen scientific papers and books fraudulently published as her work, more than 30 years after the wife of the former communist dictator Nicolae Ceaușescu was executed.

Elena Ceaușescu was celebrated by state propaganda under her husband’s regime as a world-famous chemistry researcher, despite having no credible qualifications. The researchers say some of her work is still being cited and accessed, even though she was barely literate in science and unable to recognise basic formulas taught to first-year chemistry students.

The James Webb space telescope, considered the Hubble’s successor, will stay on the ground an extra day due to high winds

Dangerously high winds will keep Nasa’s newest space telescope on the ground for at least an extra day, with the launch now targeted for Saturday – Christmas Day – at the earliest.

Nasa announced the latest delay Tuesday. Upper-level high wind could force a rocket off-course or even damage or destroy it.

Microplastics from Africa and North America found airborne in French Pyrenees, 2,877 metres above sea level

From Mount Everest to the Mariana Trench, microplastics are everywhere – even high in the Earth’s troposphere where wind speeds allow them to travel vast distances, a new study has found.

Microplastics are tiny fragments – measuring less than 5mm – that come from packaging, clothing, vehicles and other sources and have been detected on land, in water and in the air.

At least 66m-year-old fossil discovered in southern China reveals posture previously unseen in dinosaurs

Scientists have announced the discovery of an exquisitely preserved dinosaur embryo from at least 66m years ago that was preparing to hatch from its egg just like a chicken.

The fossil was discovered in Ganzhou, southern China and belonged to a toothless theropod dinosaur, or oviraptorosaur, which the researchers dubbed “Baby Yingliang”.

Tedros Adhanom Ghebreyesus says Omicron is infecting people who have been vaccinated and could double its infections every 1.5 to three days

The head of the World Health Organization (WHO) has warned that holiday festivities would in many places lead to “increased cases, overwhelmed health systems and more deaths” and urged people to postpone gatherings.

“An event cancelled is better than a life cancelled,” Tedros Adhanom Ghebreyesus said.

Loneliness is significant mental health concern and can raise risk of death by 45%, say scientists

Contact with nature in cities significantly reduces feelings of loneliness, according to a team of scientists.

Loneliness is a major public health concern, their research shows, and can raise a person’s risk of death by 45% – more than air pollution, obesity or alcohol abuse.

Death of child with Covid-19 prompts calls for Māori to be prioritised in NZ vaccine rollout

Posted on by

Māori boy who died last week was youngest New Zealander to die with virus and the first child

The first death of a child with Covid-19 in New Zealand has prompted calls for Māori children to be prioritised in the next stage of the vaccine rollout, as the country grapples with racial inequalities compounded by the pandemic.

A Māori boy, under the age of 10 and who had tested positive for the virus, died last week, becoming the youngest New Zealander to die with Covid, the Ministry of Health confirmed. It is unclear whether Covid-19 was the cause of the boy’s death, as New Zealand records all deaths of people considered active Covid cases in its official count. It is the country’s 49th death of a Covid-positive person since the start of the pandemic. Māori make up an estimated 17.1% of the population but they have accounted for 32% of all Covid-19 related deaths.

Covid live: UK reports 82,886 new cases in huge weekly jump; Omicron dominant in Ireland

Latest UK daily cases show a 72% jump on the 48,071 new infections recorded last Sunday; Irish officials say 52% of cases estimated to be new variant

The head of Germany’s domestic intelligence agency has been talking about the potential for serious acts of political violence coming from the country’s anti-vaccine movement, in which organised far right activists are increasingly involved in some regions.

Thomas Haldenwang, the president of the Federal Office for the Protection of the Constitution, said in an interview with journalists from the Funke media group: “It is true that there is a difference between talking about violence and committing it,”

The science is clear: the case for more Covid restrictions is overwhelming

Analysis: Omicron studies so far have been rapid first takes, but the message for England is loud and clear

For a variant that came to light less than a month ago, the evidence for Omicron’s potential to wreak havoc has mounted at breakneck speed. What studies have emerged are rapid first takes, but the message they convey is now loud and clear: the scientific case for more restrictions is overwhelming. Without hard and swift action to curb transmission, the NHS faces a battering.

The first red flag came in late November when scientists in southern Africa shared early genomes of what became known as Omicron. Soon after they landed, Tom Peacock, a virologist at Imperial College London, highlighted the “awful” mutations that marked it out as a fast-spreading, vaccine-dodging variant. On receiving a text about Peacock’s tweet, Dr Susan Hopkins, the chief medical adviser to the UK Health Security Agency (UKHSA), conceded it filled her with gloom.

I’m heartbroken to miss Christmas with my family – but want to inspire girls with this huge challenge

While my husband and two children celebrate Christmas without me, I will be rowing 3,000 miles across the Atlantic

For the past few weeks, I’ve been getting ready for Christmas. As well as putting the tree up ridiculously early, I’ve made the cake, bought the presents and assembled the stockings. Even though my children no longer believe in Santa, the crinkle of my dad’s old golf socks stuffed full of presents on Christmas morning still makes their faces light up.

But this year, for the first time since they were born, I won’t be there to celebrate with them. I’m leaving my husband Fred, daughter Inès, 15, and son Vincent, 12, to row 3,000 miles across the Atlantic as part of the annual Talisker Whisky Atlantic Challenge. My four-woman crew of mothers is called the Mothership, and between us we have 11 children, the youngest of whom is four.

Health workers at King’s College hospital fear a surge in admissions as the Omicron wave gathers force, but are cautiously optimistic

On the third floor of one of the country’s biggest hospital trusts, a team of intensive care specialists in masks and visors huddle around a screened bay where a critically ill patient lies unconscious surrounded by cables and tubes.

The elderly man’s breathing is supported by a ventilator and he is connected to an arterial line to measure blood pressure. He is fed by a gastric tube, and a nearby stack of six monitors provide updates on his condition, from oxygen levels to heart rate.

Is there any good news at all on Omicron? Yes, there are small signs of hope

Analysis: scientists are only starting to understand new Covid mutation but there is encouraging news from the laboratory, South Africa and on antiviral drugs

It’s hard to find much good news among the waves of grim statistics that have washed over the nation since the emergence of Omicron.

Once again, the NHS is threatened and again, the prospect of a new year lockdown looms. We seem to have gained nothing in the battle against Covid-19 during the past 12 months.

T-cells in Pfizer Covid jab recipients stay robust against severe illness

Research in South Africa raises hopes that similar responses may be present with other vaccines

South African researchers examining how the body’s immune system responds to the Omicron variant have identified that T-cells in people who have had the Pfizer vaccine continue to be robust in potentially protecting against severe illness despite Omicron’s ability to evade other defences.

The research raises hopes that similar responses may be present with other vaccines and within unvaccinated individuals who have been infected with coronavirus.

Why a UK Omicron wave is dangerous – even if we see mostly mild cases

Posted on by

Analysis: If the spread continues at this rate, a small proportion of Covid hospitalisations is a serious matter

With the booster programme at full tilt across the UK, immunity against Covid is rising – so it is perhaps not surprising that the concern shown by experts over the steep rise in Omicron infections has left some bemused.

For while the new variant is believed to dodge Covid vaccines to some degree, it is thought the jabs still offer good protection against severe disease – particularly after a booster. And greater levels of immunity mean a lower ratio of hospitalisations to cases – something we have seen before in the UK, where about 22% of cases in those aged 65 and older ended up in hospital in early 2021, when Alpha was dominant but few had received a vaccine, compared with about 6% after the vaccine rollout was well under way.

Analysis: After a steady stream of reports, how likely is it that Boris Johnson will take advice about imposing tougher restrictions?

• Boris Johnson joined No 10 party during May 2020 lockdown, say sources

Cast your minds back to 15 May 2020. Matt Hancock, the then health secretary before he quit for breaking restrictions by having an affair, was giving a press conference where he said people should be “staying at home as much as is possible”.

Social interaction was strictly limited to outdoors and one person at a time. It was the week when people were told they could meet one parent outside, in a socially distanced way, but not both of them together.

Early trials show jab effective in people of all ages who have already received doses of any vaccine

Efforts by the British and French drugmakers GSK and Sanofi Pasteur to produce a Covid-19 vaccine have suffered a further setback, with final clinical data on the jab and a potential launch delayed until next year as they struggle to find enough uninfected people to test it on.

The two vaccine specialists announced positive preliminary results from a trial that showed the vaccine raised antibody levels against Covid by nine to 43 times when given as a single booster shot in people who had already received doses of AstraZeneca, Johnson & Johnson, Moderna or Pfizer/BioNTech vaccines, for all age groups.

EU risk assessment advises against Christmas mixing owing to new Covid variant’s high transmissibility

Christmas get-togethers may need to be downsized as Omicron is now “very likely” to increase the death toll in Europe even if it proves to be less severe, the European Centre for Disease Prevention and Control has said.

The new Covid variant’s high transmissibility means that more people are forecast by the EU agency to be admitted to hospital or killed this winter than previously projected.

Why UK has been less keen than US to give Covid jab to children

Differing adult uptakes, healthcare systems and cultures of medicine have played role in approaches

The UK and US may have many things in common, but when it comes to vaccinating children against Covid, the approach has been markedly different.

In May, the US Food and Drug Administration’s emergency use authorisation of the Pfizer/BioNTech jab was expanded from people aged 16 and older to those aged 12 to 15, with two doses recommended for all those eligible.
