Jabbed adults infected with Delta ‘can match virus levels of unvaccinated’

Researchers say implications for transmission remain unclear but reaching herd immunity even more challenging

Fully vaccinated adults can harbour virus levels as high as unvaccinated people if infected with the Delta variant, according to a sweeping analysis of UK data, which supports the idea that hitting the threshold for herd immunity is unlikely.

There is abundant evidence that Covid vaccines in the UK continue to offer significant protection against hospitalisations and death. But this new analysis shows that although being fully vaccinated means the risk of getting infected is lower, once infected by Delta a person can carry similar virus levels as unvaccinated people.

WHO condemns rush by wealthy nations to give Covid vaccine booster

Move likened to handing out life jackets to those who already have them while letting others drown

The World Health Organization has condemned the rush by wealthy countries to provide Covid-19 vaccine booster shots, while millions of people around the world have yet to receive a single dose.

‘A vocal group got its way’: Florida parents condemn schools’ lack of mask mandates

Amid powerful resistance to mandates from Florida’s governor and his supporters, some parents are frustrated that others are ignoring safety protocols

In Pinellas county, Florida, Maggie, a mother of three, is sending her kids to school every day with two or three extra masks even if, in her fourth grader’s class, only a third of the children are wearing them. Just two days into the new school year, she received a call from school officials saying there were already five known cases of students with Covid-19.

“Based on my kids’ school, and the number of parents that have chosen to not mask their kids, it looks like we’re in the minority,” said Maggie, who asked to be identified by just her first name. “I think the voices who are very anti-mask are very loud.”

Asked what she would say to people who questioned the need for a level 4 lockdown, the prime minister responded with one word: ‘Australia’

But a disastrous outbreak of the Delta variant in Sydney has helped galvanise New Zealand’s “team of 5 million” – and across the country, the government’s tough strategy on Covid-19 has enjoyed widespread popular support.

Growing New Zealand Covid cluster linked to Sydney Delta outbreak

Jacinda Ardern warns of more cases as Auckland cluster grows to seven, marking New Zealand’s first local transmissions of Delta variant

Former prime minister Muhyiddin Yassin’s resignation yesterday after less than 18 months in office comes as Malaysia has one of the world’s highest infection and death rates per capita, with daily cases breaching 20,000 this month despite a seven-month state of emergency and a lockdown since June.

India has administered more than 8.8m doses of Covid-19 vaccines in the past 24 hours, government data showed, close to its all-time record and speeding up a campaign to inoculate all eligible adults by December.

India has undertaken one of the world’s largest Covid-19 vaccination drives and has so far administered 554m doses, giving at least one dose to about 46% of its estimated 944m adults. Only about 13% of the population have had the required two doses.

‘Spreading like a virus’: inside the EU’s struggle to debunk Covid lies

Understaffed and underpowered, a Brussels taskforce tries to fight a fake news tide that threatens to undermine the union itself

In April 2020, near the start of the global pandemic, Felix Kartte was working 14-hour shifts as an EU policy officer, struggling to monitor a barrage of coronavirus-linked disinformation.

Articles claiming that the pandemic was a hoax, that it was caused by 5G, that it could be cured by hydroxychloroquine or alternative medicine were going viral across the continent – part of a global phenomenon the World Health Organization warned was becoming an “infodemic.” Kartte and colleagues in StratCom, the EU diplomatic service’s strategic communications division, could detect what they say were patterns of Covid-denier and anti-vaxxer disinformation linked to Russia and to a lesser extent China, being disseminated in several languages across Europe.

Real-world data collection continues, but it’s clear that the vaccines do offer significant protection against becoming infected by Delta. They offer even greater protection against severe illness: Among states that are reporting breakthrough cases of Covid-19, fully vaccinated people made up no more than 5% of overall hospitalizations.

‘We aren’t all dumb hillbillies’: how Covid caused a rift in country music

Country stars such as Jason Isbell have received backlash for insisting on safety at their concerts, exposing an age-old political divide

The Covid-19 culture war has a new front: country music. Be it the Nashville establishment or up-and-comers in adjacent roots, folk and Americana genres, numerous artists are taking a stand about concert pandemic precautions, often along partisan lines. Jason Isbell has become one of the most prominent musicians to step into the fray. The Grammy-winning independent alt-country artist – who has released acclaimed albums like Southeastern and last year’s Reunions – rowed with some venues and vitriolic Twitter users, while also eliciting praise, after announcing on 9 August that proof of a Covid-19 vaccination or a negative test was mandatory for his show-goers.

“We have the ability to limit the number of people who get sick. So I can handle pushback from anyone refusing that, because I believe I am correct,” Isbell said.
