Primary school pupils learned 'little or nothing' from online lessons during lockdown and lost a FIFTH of the progress they would have made in the classroom, study finds

Research conducted by Per Engell, Arun Frey and Mark Verhagen found that primary school children learned very little or nothing during lockdown, without face to face teaching. The team studied evidence from the Netherlands, and suggest their findings are applicable internationally.

What we know about when the U.S. may reach herd immunity with COVID
Estimates vary, and some think it's impossible to predict when the country will meet the immunity threshold.

Professor Jennifer Beam Dowd is interviewed in this article. It's impossible to predict when herd immunity will be reached, she says. But if kids are vaccinated in the fall, the difference will be felt by New Year 2022.

The number of twins in the world is the highest it has ever been

Article about Professor Monden's research, Twin Peaks: more twinning in humans than ever before

The global rate of twin births has risen by a third since the 1980s, from 9 per 1000 births to 12 per 1000. Christiaan Monden at the University of Oxford and his colleagues generated the figures by gathering existing data from 165 countries from 1980 to 2015. Twins are also more likely to survive now, thanks to medical advances. “The rates are higher than they have been for 50 years,” says Monden. “This is likely to be an all-time high.”

Vaccine passports are coming – but they may exclude millions

To be truly safe, “these passports would have to have an expiry date on them”, explains Professor Melinda Mills, director of the Leverhulme Centre for Demographic Science. “You’d also have to be able to revoke them” in extreme cases.

EDITORIAL: COVID-19 vaccination passports

Professor Melinda Mills, lead author of the Royal Society report Twelve criteria for the development and
use of COVID-19 vaccine passports, writes this editorial on the issue.

She says: The choice about how passports are used should be guided by exemplary science, appropriate technologies, and fair use for all.

Twins peak with more born than ever before

Article on Professor Monden's research Twin Peaks: more twinning in humans than ever before

Prof Christiaan Monden, the study's author from the University of Oxford, said there was a reason for that.
"The twinning rate in Africa is so high because of the high number of dizygotic twins - twins born from two separate eggs - born there," he said.
"This is most likely to be due to genetic differences between the African population and other populations."

More twins are being born than ever before, researchers say

Article on Professor Monden's research Twin Peaks: more twinning in humans than ever before

The rise of assisted reproductive technology (ART) in developed countries since the 1970s contributed to the rise in multiple births, they said, as did mothers giving birth at an older age, when twinning rates are higher.

Research Impact

 

The Leverhulme Centre for Demographic Science is at the forefront of research relating to COVID-19. Research into the demographics of COVID-19 mortality rates, the effectiveness of face coverings and social bubbles has helped shape policy-making in response to the virus, both in the UK and internationally, as well as raising public awareness of measures to stop the spread of the virus. The research has also led to the development of a Coronavirus Hotspots Dashboard which helps local authorities to predict areas at risk of an outbreak. The initiative Dear Pandemic, co-founded by Jennifer Dowd, has disseminated the research results to a wide public audience, focusing on practical recommendations.
