Contradictory death figures in Russia; WHO warns against relaxing guard due to vaccines

India’s federal government has asked local authorities to prioritise vaccinations in several districts of eight states, including New Delhi, that have seen a spike in coronavirus cases in recent weeks.

Reuters reports:

More than 60 districts across New Delhi, Haryana, Andhra Pradesh, Odisha, Himachal Pradesh, Uttarakhand, Goa and Chandigarh, “continue to be of concern”, the government said.

“These districts are seeing a decrease in total tests being conducted, low share of (tests), increase in weekly positivity and low number of contact tracing of the COVID positive cases,” it added, citing a risk of transmission to neighbouring regions.

More than 1,000 people in north-east England have been checked for coronavirus in the first day of surge testing after a variant from South Africa was discovered in their area.

The BBC reports that everyone aged over 16 living in Stockton’s TS19 postcode area was being urged to get tested even if asymptomatic. The local council said the variant was “more infectious” and cases needed to be identified “as quickly as possible”. Early studies indicate that this variant could be much more resistant to vaccines than the original strain.

Governments urged to prioritise obese people for vaccinations over greater risk of death from coronavirus

Countries with high levels of overweight people, such as the UK and the US, have the highest death rates from Covid-19, a landmark report reveals, prompting calls for governments to urgently tackle obesity, as well as prioritising overweight people for vaccinations.

About 2.2 million of the 2.5 million deaths from Covid were in countries with high levels of overweight people, says the report from the World Obesity Federation. Countries such as the UK, US and Italy, where more than 50% of adults are overweight, have the biggest proportions of deaths linked to coronavirus.

Plan for moving from lockdown to relaxation of restrictions will be guided by data

Northern Ireland’s deputy first minister, Michelle O’Neill, has unveiled a cautious five-step plan to ease the region’s Covid-19 lockdown. The plan has no hard dates and will be led by data, notably the reproductive rate of the virus, O’Neill told the Stormont assembly on Tuesday.

The 28-page plan, titled Moving Forward: the Executive’s Pathway out of Restrictions, envisages a five-stage process moving from lockdown to relaxation of restrictions for nine different sectors.

Both countries urged to take action to avoid pile-up of unused AstraZeneca vaccine doses

Authorities in Germany and France are under pressure to come up with creative solutions to shift the AstraZeneca vaccine at higher speed in order to avoid a pile-up of unused doses over the coming weeks.

On Monday, France’s medical regulator reversed its advice not to use the AstraZeneca jab on over-65s, and Germany’s vaccination committee is coming under increasing pressure to follow suit or even scrap prioritisation altogether.

Greece reported 1,424 new coronavirus cases on Saturday, as well as 23 further deaths.

This compares with 1,222 cases and 26 deaths last Saturday.

There have been more than 3.8 million confirmed Covid-19 cases on the African continent, and more than 100,000 fatalities.

The number is understood to be an underestimation, with the director of the Africa Centres for Disease Control and Prevention (CDC) saying last week that it was “definitely not counting all the deaths, especially in the second wave”.

Over 3.8 million confirmed #COVID19 cases on the African continent - with more than 3.3 million recoveries & 100,000 deaths cumulatively.

DNA from teeth found in Siberia permafrost the oldest yet sequenced, pushing science into ‘deep time’

Teeth from mammoths buried in the Siberian permafrost for more than a million years have led to the world’s oldest known DNA being sequenced, according to a study that shines a genetic searchlight on the deep past.

Researchers said the three teeth specimens, one roughly 800,000 years old and two more than a million years old, provided important insights into the giant ice age mammals, including into the ancient heritage of, specifically, the woolly mammoth.

Scientists surprised by marine organisms on boulder on sea floor beneath 900 metres of ice shelf

The accidental discovery of marine organisms on a boulder on the sea floor beneath 900 metres (3,000ft) of Antarctic ice shelf has led scientists to rethink the limits of life on Earth.

Researchers stumbled on the life-bearing rock after sinking a borehole through nearly a kilometre of the Filchner-Ronne ice shelf on the south-eastern Weddell Sea to obtain a sediment core from the seabed.

How should we address Charles Darwin’s complicated legacy?

Posted on by

The Descent of Man, 150 years old this month, is a work of humanist brilliance – yet its errors, particularly on gender, now make for uncomfortable reading

“Light will be thrown on the origin of man and his history.” That sentence is the sole reference to human evolution in Charles Darwin’s masterwork On the Origin of Species, which in 1859 set down the theory that explains how life on Earth has evolved. Darwin had entirely excluded humans from his scheme. That tease comes in the final chapter, almost like a post-credit scene in a superhero movie, as if to simply say: “To be continued…”

The sequel did come, in the form of The Descent of Man, published in February 1871. All of Darwin’s canon is worth reading (though the one about worms and vegetable mould is perhaps a bit niche), but The Descent of Man is my favourite, because it is the one where he holds humans up to the light. Darwin was a great writer, and the prose is typically grand:

Everyone in top four categories has been offered first vaccine dose, says first minister

Wales has become the first UK nation to have offered a Covid jab to everyone in the top four priority groups, the first minister, Mark Drakeford has announced.

Last month, Drakeford was forced to defend Wales’s vaccination programme after criticism of delays from opposition parties and doctors. But at a press conference on Friday, he said that 66 days after people in Wales first began getting the jab, the key target had been achieved.

European commission leader says bloc late to authorise jabs and ‘not where it wants to be’

The EU is “not where it wants to be” with its coronavirus immunisation programme, Ursula von der Leyen has conceded, as she faced MEPs in the European parliament amid mounting criticism of the bloc’s slow deployment of vaccines.

“We were late to authorise,” the European commission president said. “We were too optimistic when it came to massive production, and perhaps too confident that what we ordered would actually be delivered on time. We need to ask ourselves why that is the case.”

Study shows Oxford Covid vaccine has less protection against South African variant

Posted on by

Researchers say vaccines’ focus must shift to protecting people from hospitalisation and death

The Oxford/AstraZeneca vaccine will not stop people becoming ill if they contract the South African variant of Covid-19, researchers have confirmed, warning that vaccines’ focus needs to shift from population immunity to protecting individuals from hospitalisation and death.

The small study in 2,000 people aged 31, who are less likely to become severely ill, adds to evidence from big trials of other vaccines carried out after the variant appeared in South Africa. Trial data from the Janssen and Novavax vaccines showed efficacy in South Africa was up to 60% against the variant, substantially lower than against the original virus.

Sputnik V vaccine has 91.6% efficacy against symptomatic Covid, Russian trial suggests

Preliminary findings based on analysis of data from more than 20,000 participants

The Sputnik V vaccine, which has been the subject of scepticism since Russia began using it last year before trials had ended, is 91.6% effective against symptomatic Covid according to data published in one of the world’s leading medical journals.

Results in the Lancet from 20,000 trial participants suggest Sputnik’s efficacy is on a par with that of some of the leading vaccines now in use. There was good efficacy in older adults, who are at highest risk for death, but little diversity, since most participants were white males.
