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.

Speaking before US authorities announced all vaccinated Americans would soon be eligible to receive booster doses, WHO experts insisted there was not enough scientific evidence to support the additional shot.

Covid news: all 16- and 17-year-olds in England to be offered first jab by 23 August – as it happened

UK department of health says the date will give teenagers change to build up immunity before school starts

We’re wrapping up the Covid live blog for today, here’s a quick summary of the latest developments:

France’s pass sanitaire health permit system will be extended to more than 120 major department stores and shopping centres on Monday in areas where levels of Covid infection are causing concern, including Paris and the Mediterranean coast.

The decision to extend the measure restricting entry to customers who can prove they have been vaccinated, have had a negative Covid test or have recovered from coronavirus was made by local officials.

The pass will now be required for shoppers entering Paris department stores such as Galeries Lafayette, Printemps, BHV, Le Mon Marché and La Samaritaine, and others mainly in the south of the country.

New Covid variants ‘will set us back a year’, experts warn UK government

Vaccine-beating variant is ‘realistic possibility’, say scientists, amid calls for contingency plans to be revealed

Ministers are being pressed to reveal what contingency plans are in place to deal with a future Covid variant that evades current vaccines, amid warnings from scientific advisers that such an outcome could set the battle against the pandemic back a year or more.

Recent papers produced by the government’s Scientific Advisory Group for Emergencies (Sage) have suggested that the arrival of a variant that evades vaccines is a “realistic possibility”. Sage backed continued work on new vaccines that reduce infection and transmission more than current jabs, the creation of more vaccine-production facilities in the UK and lab-based studies to predict evolution of variants.

‘No concept of how awful it was’: the forgotten world of pre-vaccine childhood in Australia

Until relatively recently, lethal infectious diseases stalked the lives of Australian children – including my father, Tom Keneally. Vaccines have saved millions

It’s 1940, and a five-year-old boy lies in an oxygen tent. He struggles for breath and hallucinates that his leaden toy soldiers are alive and marching around the room, monstering him with their bayonets.

He has diphtheria, a disease also known as The Strangling Angel. There is a vaccine, but not every child has been inoculated. The bacterial infection creates a membrane across the back of the throat, cutting off air supply.

UK orders extra Covid vaccines for autumn 2022 booster campaign

Pfizer reportedly asked to supply 35m more doses, with final go-ahead for this year’s programme still awaited

Ministers have started ordering vaccines for a booster campaign in autumn 2022, with Pfizer reportedly being asked to supply the UK with a further 35m doses.

The government has still not give the final go-ahead for the vaccine booster programme expected this autumn, but it is understood to have placed the order with Pfizer despite the company raising its prices.

Australia Covid live update: NSW on edge as cases spread in regions; Melbourne waits for news on lockdown

Melbourne faces the possibility of a lockdown extension as shopping centre workers ordered into quarantine; new cases emerge across regional NSW. Follow all the day’s news

Queensland LNP MP George Christensen has spoken to Sydney radio 2GB about being censured through a parliamentary motion yesterday.

The whole House, including the government, voted to support Labor’s motion disassociating the parliament with Christensen’s anti-lockdown and anti-public health measure comments yesterday (although Scott Morrison couldn’t bring himself to name or reference Christensen in his speech and just a hour or so later, cabinet minister Paul Fletcher declined five times on national TV to say he disagreed with Christensen’s views)

Happy Wednesday!

It’s not just hump day; we’re also halfway through the parliamentary sitting. At this stage, there’s a week break and then it’s back into it, but you have to wonder whether any of the east coast MPs will risk going home, given how quickly Covid is changing the landscape. Although, it doesn’t seem like anyone is missing the deputy prime minister, who has been in lockdown in Armidale, and apparently, unable to zoom in for the sitting (he has answered no questions in QT and offered no contributions to debate).

Study links women’s middle-age height loss with greater risk of death

Research suggests those with higher loss are more likely to die early, even when exercise is taken into account

Women who experience greater height loss during middle age may be at higher risk of death, research suggests.

Scientists have previously found that shorter people may have an increased risk of heart disease, with researchers saying the two appear to be linked not just by lifestyle but by genes.

Think it’s all over? Why the Covid experts are not so sure about that

Analysis: the end of restrictions in the UK has not led to a surge in cases, but coronavirus remains unpredictable

They are questions lurking in many people’s minds: just how upbeat or pessimistic should we be about the pandemic now? How does the UK compare with other countries? And is the worst of the crisis really over?

Two weeks after “freedom day” in England and with case numbers across the UK remaining lower than some modellers had feared, the worst seems to have eased. Future lockdowns, according to experts, seem unlikely unless new variants emerge.

Prof Francois Balloux: ‘The pandemic has created a market for gloom and doom’

The UCL scientist and ‘militant corona centrist’ on the risk of new variants, psychosomatic long Covid and when he expects the crisis to end

Prof Francois Balloux is director of the University College London Genetics Institute. His work focuses on the reconstruction of disease outbreaks and epidemics. With his colleague Dr Lucy van Dorp, he led the first large-scale sequencing project of the Sars-CoV2 genome. During the pandemic, he has become a prominent scientist on Twitter, where he describes himself as a “militant corona centrist”.

Would you say a new variant of concern is still the major threat to our way out of this pandemic?
We haven’t had one in a while. The four variants of concern all emerged in the second half of 2020, and it’s important to keep in mind that viruses evolve all the time at a fairly regular pace.

Vaccinologist Barbie: Prof Sarah Gilbert honoured with a doll

Co-creator of the Oxford/AstraZeneca jab hopes it will inspire young girls to enter Stem careers

Prof Sarah Gilbert has had quite a year. The co-creator of the Oxford/AstraZeneca jab has been made a dame, been given an emotional standing ovation at Wimbledon – and now a Barbie doll has been made in her honour.

Gilbert, who led the development of the Covid vaccine at Oxford University, said she initially found the gesture “very strange” but hoped it would inspire young girls to work in science, technology, engineering and mathematics (Stem).

Trial to test if cannabis-based mouth spray can treat brain tumours

First such study in the world aims to find out if Sativex combined with chemotherapy can help treat glioblastoma

Cancer charities and the NHS are preparing to investigate whether a cannabis-based mouth spray can treat brain tumours and help patients to live longer.

Doctors will give patients across the UK with a recurrent brain tumour called a glioblastoma the drug, which is known as Sativex, alongside a chemotherapy medication – temozolomide – in a clinical trial in an attempt to kill off cancerous cells.

Covid restrictions and screens linked to myopia in children, study shows

Hong Kong research suggests less time outdoors and more doing ‘near work’ accelerates short-sightedness

Spending more time indoors and on screens because of Covid restrictions may be linked to an increased rate of short-sightedness in children, researchers say.

The study, which looked at two groups of children aged six to eight in Hong Kong, is the latest to suggest that lockdowns and other restrictions may have taken a toll on eyesight: data from more than 120,000 children of a similar age in China, published earlier this year, suggested a threefold increase in the prevalence of shortsightedness, or myopia, in 2020.

Research into non-injectable Covid vaccines brings hope for needle-phobics

Scientists say anxiety around needles could be playing role in vaccine hesitancy in the UK

The sight of a needle piercing skin is enough to chill a quarter of adult Britons and trigger up to 4% into fainting. But hope is on the horizon for needle-phobics as researchers are working on a range of non-injectable Covid vaccine formulations, including nasal sprays and tablets.

Almost every vaccine in use today comes with a needle, and the approved Covid-19 vaccines are no exception. Once jabbed, the body’s immune system usually mounts a response, but scientists in the UK and beyond are hoping to harness the immune arsenal of the mucous membranes that line the nose, mouth, lungs and digestive tract, regions typically colonised by respiratory viruses including Covid-19, in part to allay the fears of needle-phobics.

Sky News Australia banned from YouTube for seven days over Covid misinformation

Digital giant issues strike after channel posted videos denying the existence of disease and encouraging people to use discredited medication

Sky News Australia has been banned from uploading content to YouTube for seven days after violating its medical misinformation policies by posting numerous videos which denied the existence of Covid-19 or encouraged people to use hydroxychloroquine or ivermectin.

The ban was imposed by the digital giant on Thursday afternoon, the day after the Daily Telegraph ended Alan Jones’s regular column amid controversy about his Covid-19 commentary which included calling the New South Wales chief health officer Kerry Chant a village idiot on his Sky News program.

As Delta spreads, Pfizer and Moderna get set for a booster shot to profits

The firms are already taking the lion’s share of earnings from the market, as this week’s results will show

Praised for preventing hundreds of thousands of deaths and allowing a return to more normal life, Covid vaccines will also substantially benefit some pharmaceutical companies.

In June, analysts estimated the global market for the vaccines could be worth $70bn (£50bn) this year, but the figure could be even higher as the Delta variant of coronavirus spreads and scientists debate whether people will need booster shots.

Sarah Perry: As an author, I felt useless in the pandemic. So I trained to be a vaccinator

Inspired by a desire to be good and help others during the pandemic, novelist Sarah Perry trained to vaccinate people. But what does it mean to be good when there is so much bad faith?

Earlier this year – lockdown three: no sign of spring – I travelled to an airport to try to be good. Dogged for months by the sense of my own uselessness, and having wept with relief and accumulated sorrow when the first Covid-19 vaccine was approved, I’d joined an organisation training volunteers to deliver vaccinations, and so arrived at a desolate Stansted shortly after dawn. Here I sat in the basement of a hotel fallen almost out of use, and in the company of a hundred strangers – though alone and masked in a square of carpet marked out with black tape – learned how to treat fainting fits, panic attacks and anaphylactic shock. In our number were a circus performer, a firefighter, a consultant of some kind; and having been starved of unfamiliar faces for so long we were all, I think, happy to be there (putting a woman in the recovery position I apologised for what seemed a shocking intimacy; but she said what a pleasure it was, after all that time, to be touched). Then we attached sponges to our upper arms, and learned how to insert the needle at 45 degrees, stretching the skin to avoid a bleed; how to depress the plunger, and then remove the needle without doing ourselves a mischief. Then, observed by the nurse, who’d hurried out of retirement to train us, we demonstrated our prowess, were awarded a certificate, and went home to await deployment.
