Latest coronavirus news as of 5.30pm on 2 July

UK prime minister “very confident” that those who received Indian-made version of AstraZeneca shot won’t have issues with EU travel

Following reports that the European Union’s covid-19 vaccine certification scheme doesn’t approve entry for people who have had a version of the Oxford/AstraZeneca vaccine manufactured in India, the UK’s medicines regulator has shared data on the vaccine with the EU’s regulator in an effort to assist with the bloc’s authorisation of the jab.

The EU’s digital covid-19 certificate allows travellers to show their vaccination status on arrival in EU countries, exempting them from quarantine. But the digital certificate launched on 1 July doesn’t accept a version of the AstraZeneca vaccine called Covishield, which is manufactured by the Serum Institute of India, because it hasn’t yet been authorised by the European Medicines Agency (EMA). The Covishield jab has been authorised by the World Health Organization (WHO), and has formed a significant portion of the vaccines allocated to low- and middle-income countries via the WHO’s COVAX scheme.

Up to 5 million people in the UK are thought to have received the Covishield vaccine, as it comprised part of the doses supplied by AstraZeneca, the Telegraph reported on 1 July. However, UK prime minister Boris Johnson told a press conference on 2 July that he was “very confident” this wouldn’t prove to be a problem for people travelling to the EU. “All AstraZeneca vaccines given in the UK are the same product,” a spokesperson from the UK’s Department of Health and Social Care told the Telegraph. The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has now shared its assessment of the vaccines with the EMA to assist in the authorisation process.

A spokesperson from the European Commission said that member states could make their own decisions on whether to allow entry for people who have received vaccines on the WHO’s emergency authorisation list, which includes Covishield. A number of European countries, including Germany, Greece, Iceland, Ireland, Slovenia, Spain and Switzerland, have already approved the Covishield vaccine for entering travellers.

Johnson & Johnson announced that its single-shot covid-19 vaccine was found to generate a strong immune response against the delta variant of the coronavirus, lasting for at least eight months after vaccination. Analysis of blood samples from eight trial participants showed that the vaccine induced stronger immune responses to the delta variant compared to the beta variant of the virus. Preliminary results so far also indicate that the Pfizer/BioNTech, Moderna and Oxford/AstraZeneca covid-19 vaccines are largely protective against the delta variant.

Australia will halve the number of international flight arrivals into the country, the prime minister Scott Morrison announced on 2 July, citing the increased risk posed by the delta coronavirus variant.

The delta coronavirus variant is now estimated to account for more than 98 per cent of all new coronavirus cases in the UK, according to figures from Public Health England.

Coronavirus deaths

The worldwide covid-19 death toll has passed 3.95 million. The number of confirmed cases is more than 182.7 million, according to Johns Hopkins University, though the true number of cases will be much higher. According to Our World In Data, more than 1.84 billion people globally have received at least one dose of a covid-19 vaccine.

UK vaccination committee advises that covid-19 vaccine booster programme should start in September

The UK’s Joint Committee on Vaccination and Immunisation (JCVI) published interim advice on covid-19 booster vaccines in England, advising that any potential booster programme should begin in September in order to maximise protection in those who are most vulnerable to serious covid-19 ahead of the winter months. 

The committee advised that immunosuppressed adults, people living in care homes for older adults, adults aged 70 and over, clinically extremely vulnerable adults and frontline health and social care workers should be prioritised for third doses of covid-19 vaccines in the first stage. “As most younger adults will only receive their second covid-19 vaccine dose in late summer, the benefits of booster vaccination in this group will be considered at a later time when more information is available,” the JCVI said in its report published on 30 June. 

On 1 July, JCVI deputy chair Anthony Harnden said the JCVI would make a decision on vaccinating children in the coming weeks. “What we need to be absolutely sure is that these vaccines benefit children in some way,” Harnden told BBC Radio 4’s Today programme. “We are looking at this data very carefully.”

Expanding the official list of covid-19 symptoms in the UK could help identify more covid-19 cases and ensure people know when to self-isolate, a group of medical researchers and public health specialists wrote in an article published in the BMJ. Official UK government guidance advises people to get a PCR test if they have any of three covid-19 symptoms, including a high temperature, a new, continuous cough and a loss or change in sense of smell or taste. However, the World Health Organization lists 13 symptoms associated with covid-19, with additional symptoms such as sore throat and headache. “Most spread is from symptomatic cases around the time of symptom onset, and interrupting transmission depends on early identification and isolation of contagious individuals. The narrow UK case definition therefore limits this detection, restricting the effectiveness of the test, trace and isolate programme,” the researchers wrote.

A 10-week decline in coronavirus infections recorded across Europe has ended and there will be a new wave in the region “unless we remain disciplined”, said World Health Organization Europe director Hans Kluge at a briefing on 1 July. Kluge urged countries to accelerate their covid-19 vaccination drives to help ensure maximum protection against the highly transmissible delta variant of the virus.

As of 6 June, an estimated 962,000 people in private households in the UK were experiencing self-reported “long covid” symptoms for more than a month after their first suspected coronavirus infection, according to a survey by the Office for National Statistics. The figure is down slightly from 1.02 million people as of 2 May.

Russia began offering covid-19 booster vaccines to people in Moscow on 1 July, as part of an effort to contain a surge of coronavirus infections thought to be linked to the delta variant.

England “on line to repeat the mistakes of last summer”, warns science adviser

A scientist advising the UK government on its covid-19 response has said that England may be at risk of repeating “the mistakes of last summer” by lifting restrictions at a time when infection rates are too high. 

“The consequence [last summer] was we never got infections low enough to be able to deal with the disease and so when conditions changed in the autumn, when schools went back and people went back to work and universities went back and the weather got worse and we went inside, so infections spiked,” said Stephen Reicher at the University of St Andrews, a member of the UK government’s Scientific Advisory Group for Emergencies, in an interview with Times Radio. “This time round, we should learn from that and we should get infections low to a point where we’re in a much better place in the autumn, where we don’t have to reimpose restrictions.” 

Restrictions in England are currently set to be lifted on 19 July. However, coronavirus cases are on the rise. According to official figures, there were 145.4 cases recorded per 100,000 people in England in the seven days up to 24 June, up from 93.8 per 100,000 the previous week.

The city of Manchester in England had a 25 per cent higher death rate from covid-19 compared to the nation as a whole from March 2020 to March 2021, a report has found. As a result, average life expectancy in North West England fell by 1.6 years among men and 1.2 years among women compared with an average in England as a whole of 1.3 years and 0.9 years, respectively. The report was commissioned in 2019 by the Greater Manchester Health and Social Care Partnership, the body responsible for health in the region, and led by University College London epidemiologist Michael Marmot. It found that the coronavirus epidemic exposed and amplified pre-existing inequalities in the region. “Greater Manchester has high levels of avoidable health inequalities as a result of longstanding economic and social inequities, and as across the country, ethnic disadvantage,” Marmot told the BBC.

North Korean leader Kim Jong Un has fired a number of senior officials over what he called a “grave incident”, potentially related to covid-19 and national pandemic-related restrictions, which “caused a great risk to people and the nation’s safety”, according to a story in the BBC based on reporting by North Korean state media. The famously reclusive regime has previously insisted that North Korea had no coronavirus cases, and the country’s borders have been closed since January 2020 in an effort to limit the spread of the virus.

French government scientific adviser Jean-François Delfraissy has warned that France may face a fourth wave of the coronavirus, due to an increase in cases caused by the delta variant of the virus. “I think we will have a fourth wave, but it will be much more moderate than the previous three waves because the level of vaccinations is different compared to before,” Delfraissy told France Info radio.

Almost half of Australia’s population more than 12 million people are now under stay-at-home orders as seven cities have recently imposed restrictions to tackle an outbreak of the delta coronavirus variant. The outbreak has risen to more than 200 cases, according to officials.

Use of FFP3 respirators increases protection of healthcare workers from coronavirus infection, according to data from one UK hospital

A UK hospital that increased the grade of medical face masks worn by healthcare workers treating covid-19 patients recorded a significant reduction in hospital-acquired coronavirus infections among those staff, a small study has found. 

Addenbrooke’s hospital in Cambridge upgraded from fluid-resistant surgical masks to filtering face piece 3 (FFP3) respirators in December, after data from routine coronavirus testing of its staff indicated that healthcare workers dealing with covid-19 patients were getting infected at a higher rate than those dealing with other patients.

After switching to FFP3 respirators, the rate of infections among healthcare workers caring for covid-19 patients fell to levels equivalent to those seen among staff working on wards without covid-19 patients. The research, which hasn’t been peer-reviewed, was published online on 24 June.

“It’s a relatively small study in one trust and so we need to see these findings replicated elsewhere,” said Mike Weekes at Cambridge University Hospitals NHS Foundation Trust, who was involved in the research. “But given the difference in the results that we’ve seen, as a sort of precautionary principle effect, what we should be thinking about is changing to use FFP3 masks for anyone caring for a patient with coronavirus,” Weekes told the BBC

Until recently, Public Health England advised that healthcare workers caring for covid-19 patients use fluid-resistant surgical masks, recommending that FFP3 respirators be used if an aerosol-generating procedure was being performed, such as inserting a breathing tube into a patient’s windpipe. However, recently updated guidance obliges NHS organisations to assess the covid-19 risk to staff and to provide FFP3 respirators where appropriate, the Guardian reported.

Some Brazilian states have seen average life expectancy pushed back to levels not seen in 20 years due to the covid-19 pandemic, according to a study published in Nature Medicine. The study found that the total reported deaths caused by covid-19 in Brazil reduced average life expectancy at birth by 1.3 years in 2020 and by 1.8 years in the period between January and April this year.

The delta variant of the coronavirus is now estimated to account for 20 per cent of new cases in France, the country’s health minister, Oliver Veran, told France Info radio on 29 June. A week earlier the variant was estimated to account for just 9 to 10 per cent of new cases in France.

Several cities in Australia have entered new lockdowns as cases associated with an outbreak of the delta variant reached about 150. Lockdowns have been imposed in the cities of Brisbane, Perth, Sydney and Darwin.

Tokyo in Japan is seeing a rise in coronavirus cases ahead of the Olympics in July. The city reported 317 new coronavirus cases on 28 June, up from 236 on the same day a week earlier.

Trial of tweaked version of Oxford/AstraZeneca covid-19 vaccine under way, in effort to boost immunity against beta variant

The first participants received a slightly modified version of the Oxford/AstraZeneca covid-19 vaccine, designed to be more effective against the beta variant of coronavirus, as part of a new trial which started on 27 June. The trial will involve about 2250 participants across the UK, South Africa, Brazil and Poland. The modified vaccine will be given to people who have previously been fully vaccinated with two doses of the original AstraZeneca vaccine, or with an mRNA covid-19 vaccine, at least three months after their most recent jab.

“The UK vaccine roll out programme has been incredibly successful at preventing hospitalisations and deaths, but we don’t know how long protection lasts,” said Maheshi Ramasamy at the University of Oxford, in a statement. “This study will provide vital evidence on whether further doses including ‘tweaks’ against new virus variants may be needed in the future.” 

Meanwhile, a small, preliminary study by researchers at the University of Oxford found that giving people a third dose of the original AstraZeneca vaccine boosted their immune response against the virus, including against the variants alpha, beta and delta, the Guardian reported. The study, which hasn’t been peer-reviewed, included 30 participants who received a third dose of the AstraZeneca vaccine at least six months after they had received their second dose.

An outbreak of the delta coronavirus variant in Sydney, Australia has grown to 128 cases. New cases have also been detected in other parts of the country, including in the Northern Territory, Queensland and Western Australia. Australia’s prime minister Scott Morrison met state and territory leaders on 28 June and agreed on new restrictions to tackle the rise in cases, including more strict quarantine rules. Under the measures, all returned travellers, as well as their close contacts, will be required to take a coronavirus test two to three days after they leave quarantine.

UK prime minister Boris Johnson has suggested that coronavirus restrictions in England won’t be lifted earlier than planned on 19 July. “We are seeing an increase in cases,” said Johnson during a campaign visit to Batley, in West Yorkshire on 28 June. “So we think it’s sensible to stick to our plan.” Sajid Javid, who has replaced Matt Hancock as UK health minister, said on 27 June that he wanted to see a return to normal “as quickly as possible”.

South Africa’s government has tightened covid-19 restrictions for at least 14 days in an effort to curb a third wave of infections. Under the new measures, all gatherings will be prohibited and there will be a curfew from 9pm to 4am.

Any adults not yet vaccinated urged to “grab a jab” this weekend

Anyone 18 or older in England is being urged to get vaccinated against covid-19 this weekend in a campaign called “Grab A Jab”. The National Health Service is expanding capacity at hundreds of walk-in clinics at shopping centres, supermarket car parks, theatres and football stadiums. People can find their nearest venue at nhs.uk/grab-a-jab.

There will also be buses offering vaccines touring around Dudley, Colchester, Ipswich and elsewhere. In some areas, community vaccinators will visit households. Text messages will be sent to people living near vaccine centres who have not had their first dose. People do not have to be registered with a family doctor to use the service.

Coronavirus vaccination was opened up to everyone over 18 in the UK last week. Since then more than a third of 18 to 24-year-olds have had the jab. “If you haven’t yet got vaccinated for whatever reason, this is the weekend to get that sorted,” Emily Lawson, NHS England’s lead for the vaccination programme, said in a statement.

Travellers to places on the green list do not have to automatically quarantine when they return to the UK, but must take PCR tests before departure and on their first day back. But UK Transport Secretary Grant Shapps warned that restrictions could change and holiday makers should ensure their bookings could be altered.

Israel has reintroduced rules that people must wear face coverings in enclosed public spaces – just ten days after the measure was lifted. The country is seeing a doubling of the number of new covid-19 cases every few days.

There are still “significant weaknesses” with the performance of NHS Test and Trace, England’s system for notifying people when they have been in contact with someone with covid-19, the National Audit Office has found. The watchdog says turnaround times are poor and the service uses too many consultants.

Long covid may have affected more than 2 million people in England

Almost 6 per cent of adults in England have had long covid, meaning they experienced at least one lingering symptom after an infection with coronavirus, suggests research by Imperial College London published on 24 June. The estimate of 2 million suffering from the condition, which is the subject of a New Scientist special feature this week, is much higher than previous studies. The figure is extrapolated from surveys by the long-running ‘REACT-2’ study, using self-reported responses from around half a million people in England who reported having covid-19. The results show some people are more likely to be affected with persistent symptoms than others: women, smokers and anyone obese or overweight is more at risk.

Such high numbers of long covid cases in England are a legacy of the country being badly affected by several waves of infections. More than 4 million people in England have tested positive for covid-19 since testing began, but the true figure is likely to be far higher as many cases go unconfirmed and testing took months to scale up at the beginning of the pandemic. The number of people with long covid points to the need for more care and support. Paul Elliott at Imperial College London, one of the new study’s authors, said in a statement: “Our findings do paint a concerning picture of the longer-term health consequences of covid-19, which need to be accounted for in policy and planning.”

The UK’s foreign travel restrictions are expected to be tweaked in an announcement around 5pm today, which is widely expected to impose fewer barriers on fully vaccinated individuals. UK prime minister Boris Johnson said the changes will offer a “real opportunity to open up travel”, but other countries may have other ideas. Germany still requires UK visitors to quarantine on arrival, regardless of their vaccination status.

China is on track to have fully vaccinated three quarters of its population by the end of this year, according to science analysts Airfinity. The group says that a “staggering” 23.6 million doses were given in China on one day, 22 June. To date, the country has administered a third of all covid-19 vaccine doses globally.

13 genetic sequences of covid-19 taken in Wuhan early in the pandemic were deleted from a US database at the request of Chinese researchers, finds a new paper, not yet peer-reviewed, by Jesse Bloom at the Fred Hutchinson Cancer Research Center. “You can’t really say why they were removed. You can say that the practical consequence of removing them was that people didn’t notice they existed,” Bloom told the New York Times.

Small study finds persistent symptoms after mild covid-19 infection in more than half of young adults

More than half of people aged 16 to 30 who had mild covid-19 were still experiencing symptoms 6 months later, a small study in Bergen, Norway has found. Bjørn Blomberg at the University of Bergen and colleagues followed up with a group of 312 people who had covid-19 during the first wave of Norway’s epidemic, including 247 people who isolated at home during their illness and 65 people who were hospitalised. They found that after 6 months, 61 per cent of all people had persistent symptoms, commonly referred to as “long covid”. Of the 61 people included in the study who were aged 16 to 30 and who had self-isolated at home during their illness, 52 per cent had persistent symptoms after 6 months. The study is published in the journal Nature Medicine.

“The findings highlight the importance of avoiding infection by control measures that include vaccination in young adults, even if they are only at risk of mild [covid-19],” said Peter Openshaw at Imperial College London in a statement. “The major caveat is that there was no control group. How many people suffer similarly after other common colds, or flu? How much did the intensive follow up and the high level of interest and anxiety affect the findings?” Openshaw added.

The European Centre for Disease Prevention and Control (ECDC) is calling for accelerated covid-19 vaccination in Europe as cases of the delta variant of coronavirus continue to rise. Modelling by the ECDC suggests that the delta variant could account for 90 per cent of all coronaviruses circulating in the European Union by the end of August. According to its most recent figures, 33.9 per cent of adults in the EU/EEA are fully vaccinated and 57.1 per cent have received at least one dose of a covid-19 vaccine. “Unfortunately, preliminary data shows that it [the delta variant] can also infect individuals that have received only one dose of the currently available vaccines,” said ECDC director, Andrea Ammon in a statement on 23 June.

A study led by researchers at the University of Oxford will trial a drug commonly used to treat parasitic infections in people with covid-19, to investigate whether it reduces the risk of hospitalisation. The Principle study will compare people given the drug, called ivermectin, to those receiving usual care.

The Australian government announced it plans to stop using the Oxford/AstraZeneca covid-19 vaccine by October, suggesting it will have sufficient supplies of other vaccines to meet its target of vaccinating the population by the end of the year.

More than 85 per cent of adults in England, Wales and Northern Ireland estimated to have antibodies against the coronavirus

An estimated 9 in 10 adults in England – or 86.6 per cent – would have tested positive for antibodies against the coronavirus in the week starting 7 June, according to the Office for National Statistics (ONS). “This is [a] remarkably high rate and most of this will be due to the impact of vaccine,” said Paul Hunter at the University of East Anglia, UK, in a statement. In Wales, Northern Ireland and Scotland, equivalent figures were 88.7 per cent, 85.4 per cent and 79.1 per cent, respectively. Across the UK, there was a clear pattern between vaccination and testing positive for covid-19 antibodies, the ONS said in its report. “Whilst immunity to [coronavirus] infection is not guaranteed in people with antibodies, the presence of antibody is strongly correlated with at least some degree of protection. So this is very good news,” said Hunter.

Pollen may facilitate the spread of the coronavirus, a modelling study has suggested. Talib Dbouk and Dimitris Drikakis at the University of Nicosia in Cyprus used a computational model to mimic the movement of a willow tree and introduced it into computer-simulated outdoor gatherings of between 10 and 100 people, some of whom were shedding coronavirus particles. The researchers found that, in their model, the tree pollen could carry virus particles along with it, potentially increasing the risk of airborne transmission. Their study, published in the journal Physics of Fluids, adds to previous research which has found a correlation between pollen concentrations and coronavirus infection rates.

Almost 250,000 pupils in England missed school last week for reasons related to covid-19, the worst attendance figures since state schools fully reopened in March, the Guardian reported.

UK to decide on booster vaccine programme following results from trials testing different vaccine combinations

Plans for a covid-19 vaccine booster programme will be announced in the coming weeks, UK health minister Matt Hancock has said. On 21 June, Hancock told BBC Breakfast that ministers were waiting for results from trials testing the effects of different combinations of covid-19 vaccines. “In the next few weeks, when we get the clinical data through on what’s the most effective combination [of covid-19 vaccines] to have […] then we’ll set out all the details for the booster programme for the autumn,” said Hancock. Speaking to reporters on the same day, UK prime minister Boris Johnson said the NHS could face “big pressures” in winter with flu season and that it is unlikely that restrictions in England would be lifted before 19 July.

More than four in five adults across the UK have received a first dose of a covid-19 vaccine as of 21 June, and 59.5 per cent have received two vaccine doses. The World Health Organization (WHO) has previously advised that wealthy countries, such as the UK, should donate spare covid-19 vaccine doses to poorer nations before arranging to give third doses to fully vaccinated people. “Top-ups and other extra things and extra protection for people in the wealthy countries […] should come a bit later,” David Nabarro, WHO special envoy on covid-19, told the BBC in May.

In South Africa, where just 1.8 per cent of adults are fully vaccinated and cases are surging, the country’s president Cyril Ramaphosa criticised the refusal of pharmaceutical companies and governments to support emergency waiving of patents on covid-19 vaccines. “It is selfish, it is unjust, it is wholly unfair,” Ramaphosa told the opening session of the Qatar Economic Forum on 21 June. “We are facing an emergency that is affecting the entire world.”

Other coronavirus news

The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) has said that current evidence doesn’t suggest an increased risk of either menstrual disorders or unexpected vaginal bleeding following covid-19 vaccination. The Sunday Times reported that the MHRA had received 3598 reports of period problems following covid-19 vaccination in the UK as of 17 May. “Anecdotally some women seem to be reporting heavier periods after receiving the COVID-19 vaccine and we would support more data collection in this area to understand why this might be the case,” said Sue Ward, vice president at the Royal College of Obstetricians and Gynaecologists, in a statement.

Shortages of the Pfizer/BioNTech covid-19 vaccine in Australia are expected to slow the country’s rollout through June and July. The delay is partly due to recently updated health advice in Australia, which means the Oxford/AstraZeneca covid-19 vaccine is no longer recommended for people aged 59 and under.

Myanmar reported its highest daily increase in coronavirus cases since a coup in February, in which the military seized power, detaining elected leader Aung San Suu Kyi. On 21 June, state media reported 546 new cases had been registered on 19 June, which is thought to be the highest daily increase since 1 February.

Delta variant cases of covid-19 in the UK have drastically risen in the past week

The UK is continuing to see rising coronavirus infections, with the delta variant of the virus now estimated to account for 99 per cent of new cases. According to Public Health England, the number of confirmed cases of the delta variant has risen from 33,630 last week to 75,953 this week. On 18 June, World Health Organization (WHO) chief scientist Soumya Swaminathan told a news conference that the delta variant is “well on its way to becoming the dominant variant globally”.

“This variant that has now taken over from the alpha [variant] is clearly significantly more infectious,” Adam Finn, a member of the UK’s Joint Committee on Vaccination and Immunisation, told the BBC. “Regrettably, it is more likely to end you up in hospital if you’re unlucky enough to get it.”

An estimated 119,000 people across the UK had covid-19 in the week up to 12 June, according to the latest results from a random swab testing survey by the Office for National Statistics – an increase from 110,000 the previous week. There were 11,007 daily new coronavirus cases reported in the UK on 17 June, the largest daily increase since mid-February.

“The one bit of good news around this is that the rate of rise of hospitalisations is not as fast as the rate of the rise in cases. So we are preventing a lot of hospitalisations with the vaccine programme, but not all of them,” said Finn, adding that “now is the time to get immunised”.

A small study suggests previous coronavirus infection doesn’t necessarily provide long-lasting immune responses

People who have been previously tested positive for the coronavirus may not be protected against becoming infected again, as the coronavirus doesn’t necessarily trigger long-lasting immune responses, according to a small, preliminary study. “In our view, previous infection does not necessarily protect you long-term from SARS-CoV-2, particularly variants of concern,” said Eleanor Barnes at the University of Oxford, one of the senior authors on the study. “You shouldn’t depend on it to protect you from subsequent disease, you should be vaccinated,” Barnes told the Guardian.

Barnes and colleagues looked at blood samples from 78 healthcare workers who tested positive for the coronavirus between April and June 2020. Of the 78 study participants, 66 had a symptomatic infection while 12 had an asymptomatic infection. The blood samples were taken monthly for up to six months after their infection and were analysed for a range of immune responses. 

The analysis revealed that six months after infection the majority of the healthcare workers who had experienced a symptomatic coronavirus infection had a detectable immune response. However, more than a quarter didn’t – and of those participants that had an asymptomatic coronavirus infection, 91.7 per cent had no detectable antibodies that could neutralise the alpha variant of the coronavirus, which was prevalent at the time of the study. None had detectable levels of antibodies that could neutralise the beta variant. The study didn’t look at the delta variant, now dominant in the UK.

The study, conducted with the UK Coronavirus Immunology Consortium, was released online on 15 June and hasn’t been peer-reviewed.

Scientists are calling for the UK government to suspend daily contact testing trials in schools in England, in an open letter to UK education minister Gavin Williamson published in the BMJ. The aim of the trials is to evaluate the effectiveness of regular lateral flow testing for coronavirus in schools, as an alternative to 10-day isolation for the contacts of pupils who contract covid-19. However, the letter argues that the risks posed by the trials outweigh their benefits, as lateral flow tests can miss early-stage infections which may contribute to the spread of the delta variant of coronavirus. It comes as a study commissioned by the government found that coronavirus infections in England increased by 50 per cent between 3 May and 7 June, as the delta variant became more prevalent.

Japan announced it would lift a state of emergency in Tokyo and eight other prefectures, while maintaining some social distancing measures, such as limiting spectator numbers at large events.

Covid-19 vaccinations to be made mandatory for care home staff in England under proposed UK plans

The UK government plans to make covid-19 vaccinations compulsory for care home staff, ministers are expected to announce. On 15 June, the Guardian reported that the government intends to push ahead with the mandatory vaccination plan, which will affect the majority of the approximately 1.5 million people who work in social care in England, despite employer and staff organisations warning that it could backfire if staff who don’t wish to get vaccinated decide to quit. The plan could also be extended to all NHS staff.

“Encouraging vaccination is always preferable to a mandatory requirement,” said Helen Bedford at University College London in a statement. “Indeed, evidence from a recent study of health and care workers suggests that where they felt pressured to have [a covid-19] vaccine, they were less likely to do so.”

Gino Martini, chief scientist at the Royal Pharmaceutical Society, said that while the society strongly encourages all pharmacists to get vaccinated if they can, it does not agree with making covid-19 vaccinations mandatory. “Informed and educated choices about health interventions would be more beneficial long-term than enforcing them,” Martini said in a statement.

According to NHS England figures, 83.7 per cent of eligible staff in older adult care homes are reported to have received at least one dose of covid-19 vaccine as of the week ending 6 June, and 68.7 per cent are reported to have received two doses. Residents in care homes for older adults and their carers are in the top Joint Committee for Vaccination and Immunisation priority group for covid-19 vaccination.

The European Union has added the US to its safe travel list, meaning people travelling to the bloc from the US will no longer need to quarantine on arrival if they present a negative coronavirus test. Other countries added to the EU’s safe list include Albania, North Macedonia, Serbia, Lebanon, Taiwan, Macau and Hong Kong. The UK hasn’t been added to the list due to “serious concerns” about the delta variant of coronavirus and recent rises in cases, an EU diplomat told the Guardian.

Text messages published by UK prime minister Boris Johnson’s former aide, Dominic Cummings, reveal that Johnson described UK health minister Matt Hancock as “totally fucking hopeless” during the early stages of the UK’s epidemic in 2020. The messages were part of a conversation between Johnson and Cummings regarding the UK’s failure to accelerate its coronavirus testing scheme.

People aged 18 and over in England should be eligible for covid-19 vaccine appointments in coming days

All people over the age of 18 in England are expected to become eligible for covid-19 vaccination this week, as more than 41 million people across the UK have now received at least one dose of vaccine. “I expect that by the end of this week, we’ll be able to open up the National Booking Service to all adults aged 18 and above,” chief executive of NHS England, Simon Stevens told the NHS Confederation conference on 15 June. “By 19 July we aim to have offered perhaps two-thirds of adults across the country double jabs,” said Stevens. 

On 14 June UK prime minister Boris Johnson announced that planned lifting of restrictions in England, originally scheduled for 21 June, would be postponed until 19 July to allow more time for people to be vaccinated. Figures from Public Health England show that two doses of covid-19 vaccine are 80.8 per cent effective against symptomatic disease caused by the delta variant – which now accounts for more than 90 per cent of new UK coronavirus cases – whereas a single dose of vaccine is much less effective, only providing 33.2 per cent protection. More than 29 million people in the UK have received two doses of covid-19 vaccine so far.

UK cabinet office minister Michael Gove has suggested that people in the UK will have to learn to accept a certain level of deaths from covid-19 once restrictions are lifted. “We can provide people with the best protection possible through the vaccination programme but, as with flu, we know that every year there are a number of people who contract it, and every year certainly there are a number of people who are hospitalised and who suffer as a result of it,” Gove told Times Radio on 15 June.

Delayed lifting of restrictions in England “justified” due to threat posed by delta variant, say scientists

UK prime minister Boris Johnson is expected to announce a four-week delay to the lifting of coronavirus restrictions in England. The BBC reported on 14 June that senior UK government ministers have signed off on the decision and Johnson is expected to confirm the delay at a news conference at 6pm UK time on 14 June. Mark Woolhouse at the University of Edinburgh said the delay “would be justified”. In a statement, Woolhouse said: “The arrival of the delta variant has changed the assessment of the risks of re-opening: it is more transmissible, causes more severe disease and the vaccines are less effective against it.”

A four-week delay to easing of restrictions in England could reduce pressure on healthcare services. Statistical modelling seen by ministers suggests that even with the rapid rollout of covid-19 vaccines, the UK will face a third wave of infections, mainly among younger people who haven’t yet been vaccinated, the Guardian reported on 13 June. “We are much busier now in emergency departments than at the peaks of either the first or second wave,” Raghib Ali, a consultant at the Oxford University Hospitals NHS trust told the Guardian. “In other parts of the hospital we are catching up with a lot of elective work because of the backlog, so for both of those reasons it’s a very bad time to have additional pressure from covid-19,” said Ali.

Other coronavirus news

A headache, sore throat and runny nose are now the most frequently reported symptoms of covid-19 in the UK, according to data from the ZOE Covid Symptom Study. The change may be linked to the increased prevalence of the delta variant (also called B.1.617.2), which now accounts for more than 90 per cent of UK coronavirus cases. “This variant seems to be working slightly differently,” Tim Spector, who runs the ZOE Covid Symptom Study, told the BBC. “People might think they’ve just got some sort of seasonal cold and they still go out to parties. We think this is fuelling a lot of the problem,” he said. “It might just feel like a bad cold or some funny ‘off’ feeling – but do stay at home and do get a test.”

A covid-19 vaccine candidate developed by US company Novavax was found to be 90 per cent effective overall at preventing covid-19. The trial, which included 29,960 participants across 119 sites in the US and Mexico, found that the vaccine was 100 per cent effective at preventing moderate to severe disease and 93 per cent effective at preventing covid-19 caused by coronavirus variants of concern. During the trial, the alpha variant (also known as B.1.1.7) became the dominant variant in the US, Novavax said in a statement.

A nascent plan by G7 nations to donate one billion vaccine doses has been criticised for not going far enough

G7 and EU leaders meeting in Cornwall, UK, from today are expected to announce plans to donate a billion vaccine doses to lower-income countries. The US has already announced that it will donate 500 million doses, and the UK 100 million. But the G7 plan has come under fire even before it has been formally announced.

“The new US and UK commitments are a step in the right direction, but they don’t go far enough, fast enough,” said Alex Harris, director of government relations at the Wellcome charity in the UK, according to Reuters. “We urge G7 leaders to raise their ambition.”

“If the best G7 leaders can manage is to donate 1 billion vaccine doses then this summit will have been a failure,” said Oxfam’s health policy manager Anna Marriott as saying. Marriott said the world needs 11 billion doses to end the pandemic.

The Oxford/AstraZeneca coronavirus vaccine might have an extremely rare side effect called capillary leak syndrome, the European Medicines Agency (EMA) has warned after its safety committee reviewed six cases. Most of these occurred in women within four days of vaccination. The EMA says people who have previously suffered from capillary leak syndrome – which can result in fluid leakage from small blood vessels, swelling and low blood pressure – should not be given the vaccine. The agency notes that more than 78 million people have had the AstraZeneca vaccine in the EU and UK.

The province of Punjab in Pakistan has said it will block the mobile phones of people who refuse to get vaccinated against the coronavirus. The province includes the city of Lahore, population 11 million. According to AFP, a spokesperson for the Punjab primary health department said the decision had been taken because people had been very hesitant to get coronavirus vaccines, and that the state telecoms agency will decide how to implement the measure. The province of Sindh has previously said civil servants who refuse to be vaccinated will not be paid from July.

The US Food and Drug Administration (FDA) has warned people in the US to stop using a rapid coronavirus test made by Innova – the same test being widely used in the UK.

UK health secretary Matt Hancock questioned on government’s handling of pandemic

The delta variant first identified in India is now causing 91 per cent of coronavirus infections in the UK, said health secretary Matt Hancock. He told MPs this was according to an assessment he saw on Wednesday evening. Hancock was speaking during more than four hours of questioning by MPs on the science and health committees.

On the government’s decisions at the start of the pandemic, Matt Hancock said they knew from the start that up to 820,000 people could die from covid-19, but ordering an earlier lockdown would have meant going against scientific advice. “The clear scientific advice at the time was that there was a need to have these tools like lockdown at your disposal but also that the consequences and the costs of lockdown start immediately and, critically, the clear advice at the time was that there’s only a limited period that people would put up with it. Now, that proved actually to be wrong,” Hancock said.

Hancock also said there was never a national shortage of personal protective equipment (PPE) for medical staff, despite reports of doctors and nurses having been forced to improvise. “We’ve looked into this and there is no evidence that I have seen that a shortage of PPE provision led to anyone dying of covid,” he said.

Asked why care home residents were allowed to return to homes from hospital without being tested, he said testing someone without symptoms “could easily return a false negative and therefore give false assurance that that person did not have the disease”.

Eight in ten adults in most of UK have covid-19 antibodies

About eight in ten adults in England now have antibodies against the coronavirus, according to the latest survey from the Office for National Statistics (ONS). Levels are similar in Wales and Northern Ireland, but slightly lower in Scotland, at seven in ten adults. The survey of UK households was carried out in the week beginning 17 May, asking people to provide blood samples and for information on whether they had been vaccinated.

The presence of antibodies indicates that people have either had at least one coronavirus vaccine or a natural infection with covid-19. “But the detection of antibodies alone is not a precise measure of the immunity protection given by vaccination,” says the ONS. The survey also found that 71-82 per cent of adults said they had received one dose of the vaccine and 38-53 per cent said they had had both doses. 

Other coronavirus news

The Moderna vaccine against covid-19 is likely to give better protection against new variants of the coronavirus than a natural infection, a study suggests. The work was based on testing antibodies from people’s blood against mutated virus spike proteins made in the lab. The researchers found that antibodies from people who had received the mRNA vaccine bind to a broader variety of spike proteins – which the virus uses to infect cells – than antibodies from people who had been naturally infected with covid-19. “People may have differing susceptibility to variants, depending on the way in which they acquired their immunity against the virus,” Allison Greaney at Fred Hutchinson Cancer Research Center in Seattle, Washington, said in a statement.

The AstraZeneca covid-19 vaccine may be causing a further kind of rare blood clotting disorder, called idiopathic thrombocytopenic purpura (ITP). This vaccine, as well as that made by Johnson & Johnson, have previously been linked with a rare syndrome where people have unusual blood clots accompanied by low platelet levels. A new Scottish study has found the AstraZeneca jab may also be causing ITP at a rate of one in 100,000 doses.

Coronavirus cases in the US are at their lowest level since March last year, averaging about 14,000 new infections a day in the past week. But the US could be the next country after India and the UK to see a significant rise in cases because of the delta (Indian) variant, according to UK experts speaking at a press briefing today. The latest estimate is that delta is 60 per cent more transmissible than the alpha variant which first emerged in the UK, according to Neil Ferguson at Imperial College London.

Covid-19 news: England lockdown easing could be delayed by two weeks

Likely delay for rollback of lockdown restrictions in England

England’s final stage of easing lockdown restrictions is likely to be put back by at least two weeks, a government source has told The Times. An end to social distancing rules, such as the “rule of six” or two households for indoor gatherings, and a ban on nightclubs and mass gatherings, had been pencilled in for 21 June.

But after a “downbeat” briefing yesterday from England’s chief medical officer Chris Whitty and chief scientific advisor Patrick Vallance, ministers are now considering the delay. The advisors pointed out that covid-19 vaccines currently available give less protection against the delta variant of the coronavirus, which was first identified in India. It also seems to be more transmissible.

Other coronavirus news

People in Greater Manchester and Lancashire were today asked to take extra social distancing precautions due to rising numbers of people infected with the delta variant. The measures include meeting people outside wherever possible, keeping two metres’ distance, and minimising travel into and out of the areas. The guidance already applied to several other areas of the UK including Bedford and Leicester. Health Secretary Matt Hancock said all affected areas would get supervised testing in schools and support for all residents to be tested twice a week. The stricter rules now apply to a tenth of England’s population.

The delta variant of the coronavirus is becoming the primary cause of covid-19 cases in England, replacing the variant first identified in Kent, a study has found. Leon Danon of the Joint Universities Pandemic and Epidemiological Research (JUNIPER) consortium and colleagues analysed variants through routine surveillance testing in England. “This is a variant that’s very likely to dominate everywhere,” says Danon.

People who catch the coronavirus after being vaccinated have milder symptoms and are less likely to transmit the virus, a US study has found. The research followed nearly 4000 healthcare staff and other key workers who were tested weekly since December. Those who got “breakthrough” infections after one or two doses of vaccine had 40 per cent less virus in their bodies and spent 2.3 fewer days in bed than people who had not been vaccinated.

Healthcare and social care staff in England are experiencing critical levels of burnout due to the covid-19 pandemic, a report by parliament’s health and social care committee has found. Lack of staff means workers are being overstretched, said the MPs.

People in the UK have been advised by environment secretary George Eustice to take holidays in their home country this year. However, travel to other countries is still permitted, under rules based on whether they are on the green, amber or red lists.

People aged 25 to 29 will be invited to book vaccines from tomorrow

Covid-19 vaccines will be offered to people aged 25 to 29 from tomorrow in the UK, health secretary Matt Hancock has announced. 

“From this week we will start offering vaccinations to people under 30, bringing us ever closer to the goal of offering a vaccine to all adults in the UK by the end of next month,” he told MPs.

Hancock also said he has asked the Joint Committee on Vaccination and Immunisation (JCVI) to advise on whether the vaccination programme should be extended to children, following the decision by the medicines regulator to approve the Pfizer/BioNTech jab for children aged 12 to 15.

The delta variant of the coronavirus, which now makes up the vast majority of new infections in the UK, has made the vaccination race tighter, Hancock said. However, the numbers of people being hospitalised with the virus remain flat, and most of them are those who have not been vaccinated.

Out of 12,383 cases of the delta variant as of 3 June, 464 went on to present at emergency care and 126 were admitted to hospital. Of those, 83 were unvaccinated, 28 had one dose of vaccine and three had both doses, Hancock said.

He added that it was too early to say whether stage four of the plan to end lockdown would go ahead on 21 June. “The road map has always been guided by the data and as before, we need four weeks between steps to see the latest data and a further week to give notice of our decision. So we’ll assess the data and announce the outcome a week today on 14 June,” Hancock said.

The Indian government will provide free covid-19 vaccines for all adults from 21 June, prime minister Narendra Modi has announced. Less than 4 per cent of the country’s population has been fully vaccinated so far, according to Our World in Data.

Businesses in Delhi and Mumbai have begun reopening as part of a phased easing of lockdown measures in several states. India’s daily recorded coronavirus infection numbers have fallen from 400,000 a month ago to around 100,000.

All adults in Wales will be offered a coronavirus vaccine by next Monday, first minister Mark Drakeford has said. If achieved, the milestone will come six weeks ahead of schedule, with the four UK nations previously saying they would offer a first dose to everyone over the age of 18 by the end of July.

Ireland has taken another stride back to normality as pubs, restaurants and leisure facilities reopened. Hospitality venues can serve food and drinks outdoors, while gyms, swimming pools and leisure centres are now allowed to facilitate individual training.

There were 12,431 cases of the delta variant in the UK as of 3 June

The delta variant of the coronavirus has become the dominant variant of coronavirus in the UK according to data from Public Health England, as the total number of confirmed cases caused by the delta variant has increased to 12,431 as of 3 June, up from 6959 a week earlier. The rise in coronavirus cases across the UK may be related to the spread of the highly-transmissible delta variant

Neil Ferguson, a scientist who has advised the UK government on covid-19, said the delta variant of coronavirus may be 30 to 100 per cent more transmissible than the previously dominant alpha variant of the virus. “The best estimate at the moment is this variant may be 60 per cent more transmissible than the alpha variant,” Ferguson told BBC Radio 4’s Today programme on 4 June. “There’s some uncertainty around that depending on assumption and how you analyse the data, between about 30 per cent and maybe even up to 100 per cent more transmissible,” he added. 

Ferguson told New Scientist that he believes more data on the transmissibility of the delta variant will be released in documents from the UK government’s Scientific Advisory Group for Emergencies on 8 June.

Kaori Yamaguchi, a Japanese Olympic official, criticised the International Olympic Committee (IOC) for ignoring public concerns about holding the Games in Tokyo during the coronavirus pandemic. Yamaguchi said the Japanese government and the IOC had been “avoiding dialogue” and that the IOC “seems to think that public opinion in Japan is not important”. Coronavirus cases in Tokyo have fallen slightly following a recent surge but on 4 June, Japan’s medical adviser Shigeru Omi warned that an increase in people’s movements during the Olympics could spark a fresh outbreak.

US chief medical adviser Anthony Fauci is urging China to release the medical records of nine people whose illnesses may provide insights into the origins of the coronavirus. The nine individuals in question include three researchers at the Wuhan Institute of Virology who reportedly became ill in November 2019 and six miners who became ill after entering a bat cave in 2012. “It is entirely conceivable that the origins of SARS-CoV-2 was in that cave and either started spreading naturally or went through the lab,” Fauci told the Financial Times.

Weekly coronavirus cases in England rise as Portugal removed from UK’s “green list” for travel

Coronavirus cases in England are continuing to rise, with the number of people testing positive for the virus at its highest level in six weeks. A total of 17,162 people tested positive for the coronavirus in England in the week up to 26 May, up 22 per cent from 14,051 the previous week, according to figures from NHS Test and Trace. The most recent weekly figure is the highest since the week up to 14 April, when 18,050 people tested positive.

Half of UK adults are now fully vaccinated against covid-19, UK vaccines minister Nadhim Zahawi announced. In a tweet on 3 June, Zahawi described it as an “important milestone”.  

Portugal is being removed from the UK’s “green list”, which means travellers returning to England from trips there will be required to quarantine on arrival. According to data from Portugal’s health ministry, cases in the country are rising. There were 724 new cases reported on 2 June, the highest daily increase since 6 April. “We have got to follow the data and, of course, I understand why people want to travel but we’ve got to make sure we keep this country safe,” UK health minister Matt Hancock told the BBC. No new countries have been added to the green list, the BBC reported on 3 June.

More than 20 medical and healthcare organisations in the UK, including the British Medical Association and the Royal College of Nursing, are calling for stricter guidelines on face masks and other personal protective equipment for healthcare workers. In a virtual meeting with government officials, representatives from the organisations are expected to argue that existing rules in the UK leave them vulnerable to coronavirus infection through the air and that healthcare workers in other countries, such as the US, are provided with higher-grade equipment, the BBC reported. This comes as a preliminary study, led by Mark Green and Malcolm Semple at the University of Liverpool in the UK, found that covid-19 prevalence in England between 1 May 2020 and 31 January 2021 was highest among people working in the hospitality, transport, social care, retail, health care and educational sectors.

US president Joe Biden announced a national “month of action” on 2 June, with a new goal of getting at least 70 per cent of people in the country vaccinated against coronavirus before the 4 July public holiday. Biden encouraged people under 40 to “step up” and get vaccinated. On 3 June, the US outlined its plans for allocating covid-19 vaccine doses for donation to other countries. At least 75 per cent of the first 25 million vaccine doses will be shared through COVAX, a World Health Organization-backed platform for ensuring equitable access to vaccines globally. The remainder will be shared directly with countries currently “experiencing surges”, the White House said in a statement, “including Canada, Mexico, India, and the Republic of Korea”.

A German police force has established a dedicated team to deal with a growing illegal trade in fake covid-19 vaccine certificates. Police in Cologne said fake certificates were being traded via the encrypted Telegram messaging service. Fully vaccinated people in Germany are exempt from certain covid-19 restrictions for instance, they can visit restaurants without presenting a negative coronavirus test.

Proportion of deaths due to covid-19 in England and Wales at lowest level since September, but coronavirus cases in the UK are rising

There were 107 deaths from covid-19 in England and Wales in the week up to 21 May, down from 151 the previous week, according to the Office for National Statistics. Covid-19 accounted for 1.1 per cent of all deaths in the week up to 21 May, which is the lowest proportion recorded since the week up to 11 September, when the disease accounted for 1 per cent of all deaths in the two nations. 

On 1 June, the UK reported no covid-19 deaths within 28 days of a positive test, for the first time since July 2020. In a statement, Nathalie MacDermott at King’s College London said that, while zero daily covid-19-related deaths “is certainly something to be celebrated, we must remember that this follows a three day bank holiday weekend during which time deaths may not have been formally reported [or] recorded”.

Scientists advising the UK government have recently expressed concerns about rises in case numbers in the country considering plans to lift restrictions in England on 21 June, as well as the threat posed by the delta variant of the coronavirus (also called B.1.617.2). According to Our World In Data, the number of daily new coronavirus cases per million people in the UK has been rising since 19 May. There were 48.73 new cases per million people on 1 June, compared to 22.36 on 19 May.

Israel’s health ministry reported a small number of cases of heart inflammation observed mainly in young men who had received the Pfizer/BioNTech covid-19 vaccine. A study it commissioned found 275 cases of the condition, called myocarditis, among more than 5 million vaccinated individuals. Pfizer said it has not observed a higher rate of myocarditis among vaccinated people than would normally be expected to occur in the general population. On 28 May, the EU’s medicines regulator said it had received 107 reports of myocarditis following the vaccine, mainly in people under 30, but said there was no indication that the cases were due to the vaccine. Last month, a US Centers for Disease Control and Prevention advisory group recommended further study of the possibility of a link between myocarditis and mRNA vaccines, including the Pfizer/BioNTech and Moderna vaccines.

There is nothing “currently in the data” to suggest planned easing of restrictions in England on 21 June should be delayed, says UK prime minister

There are currently no plans to delay easing of coronavirus restrictions in England from 21 June, according to UK prime Minister Boris Johnson. On 1 June, a spokesperson for Johnson told journalists who asked about the timeline to refer to comments made by Johnson on 27 May, when he said he didn’t see “anything currently in the data” that would divert him from the scheduled easing of rules. The spokesperson added: “We will continue to look at the data, we will continue to look at the latest scientific evidence as we move through June towards June 21.” 

However, scientists advising the UK government are already warning that it may be necessary to delay the planned lifting of restrictions in England. Ravi Gupta at the University of Cambridge, a member of the New and Emerging Respiratory Virus Threats Advisory Group, told ITV’s Good Morning Britain that a delay of a few weeks could have a significant impact on the UK’s battle against covid-19 and recommended it should be made clear to the public that it would be a temporary measure based on the surge in cases of the new variant.

In Scotland, covid-19 restrictions will be lifted in some parts of the country on 5 June but much of the country will retain tougher measures due to recent spikes in virus cases, Scotland’s first minister Nicola Sturgeon told Scottish Parliament on 1 June. Edinburgh and Midlothian, Dundee, East Dunbartonshire, Renfrewshire, East Renfrewshire, North, South and East Ayrshire, North and South Lanarkshire, Clackmannanshire and Stirling have not yet met the criteria to see restrictions ease, Sturgeon said.

Nearly 7000 cases of the coronavirus variant identified in India have been confirmed across the UK

As of 27 May, 38.5 per cent of new coronavirus infections in the UK were cases of the B.1.617.2 variant of the virus first identified in India, according to data from Public Health England. Mass testing and vaccination drives are continuing in areas most affected by the variant, including in Bolton, UK health minister Matt Hancock told a press briefing on the same day. Public Health England data shows that 6959 cases of the variant had been confirmed in the UK in total by 27 May, up from 3424 cases the previous week, and Hancock said the variant could account for up to three-quarters of all UK cases

Despite recent rises in coronavirus cases in the UK, Jenny Harries, chief executive of the UK’s Health Security Agency, said there hasn’t been a “sharp increase” in hospitalisations. However, on 27 May, Neil Ferguson at Imperial College London told BBC Radio 4’s Today programme that concerns remain about the transmissibility of the B.1.617.2 variant and that “data collected in the next two to three weeks will be critical”. Ferguson said the government’s plan to ease restrictions in England on 21 June “hangs in the balance”, adding: “The key issue as to whether we can go forward is, will the surge caused by the variant – and we do think there will be a surge – be more than has been already planned in to the relaxation measures?”

Preliminary research suggests rare blood clots linked to some covid-19 vaccines may be related to their DNA delivery mechanism

Researchers may have identified a cause of the rare blood clots associated with the Oxford/AstraZeneca and Johnson & Johnson (J&J) covid-19 vaccines. Preliminary research by Rolf Marschalek at Goethe University in Frankfurt and his colleagues indicates the problem is related to the method by which these vaccines deliver DNA instructions for the assembly of the coronavirus spike protein inside cells. This so-called viral vector technology is used in both the Astrazeneca and J&J covid-19 vaccines. 

The DNA is delivered to the cell’s control centre, called the nucleus, rather than the surrounding fluid where the virus would usually produce proteins, according to Marschalek and colleagues in a non-peer-reviewed study posted online on 26 May. In the cell nucleus, parts of the DNA encoding the coronavirus spike protein are split apart, creating incomplete versions that aren’t able to bind to the cell’s outer membrane where they would be detected by the body’s immune system. Instead, they are released into the blood, where they may trigger the blood clots in rare cases, Marschalek told the Financial Times

Marschalek said a solution may be to modify the gene sequence in the vaccine in a way that prevents this splitting. He said J&J had already contacted his laboratory for advice and is trying to optimise its vaccine.

US president Joe Biden has ordered the US intelligence community to increase its efforts in investigating the origins of the coronavirus pandemic. “I have asked for areas of further inquiry that may be required, including specific questions for China,” Biden said in a statement on 26 May. On 23 May, the Wall Street Journal reported that three researchers from China’s Wuhan Institute of Virology sought hospital care in November 2019 with symptoms consistent with covid-19. China’s Foreign Ministry and the director of the Wuhan National Biosafety Lab denied the report, and a World Health Organization investigation previously concluded that it was “extremely unlikely” that the virus originated in a laboratory.

The head of the Japanese Doctors Union, Naoto Ueyama, said that holding the Olympic Games in Tokyo in July as planned could lead to the emergence of a “Tokyo Olympic strain” of coronavirus. Japanese officials, Olympics organisers and the International Olympic Committee have said the Olympics will go ahead with strict virus-prevention measures in place. But concerns remain about the risks posed by athletes and officials from around the world converging in Japan, Ueyama told a news conference on 27 May. 

Covid-19 hospitalisations in England have increased slightly, according to the weekly national influenza and covid-19 surveillance report from Public Health England (PHE) . Hospital admission rates for covid-19 rose slightly to 0.79 per 100,000 people, up from 0.75 per 100,000 people the previous week. “This is a reminder that we still have a way to go and need to remain cautious,” said Yvonne Doyle, PHE medical director, in a statement.

Researchers estimate that up to 30 per cent of covid-19 health burden could be due to lasting effects requiring long-term care

As much as 30 per cent of the health burden of covid-19 could be a result of lasting effects that need long-term care, rather than deaths, according to Anna Vassall and Andrew Briggs at the London School of Hygiene & Tropical Medicine. They estimated this using measures known as disability-adjusted life years and quality-adjusted life years that capture the impact of ill health on a person’s life course. It’s “a very rough first estimate based on simple assumptions”, they write in an article published in Nature

The overall magnitude of these lingering effects, which can range from fatigue to cardiovascular disease, has been greatly underestimated, Vassall told New Scientist, so the impact on younger people is greater than thought. 

“We worry that everyone is focusing their strategy on deaths, and hence the old, when they are prioritising vaccines,” says Vassall. Health authorities need to look at the broader disease burden, she says.

Dominic Cummings, former aide to UK prime minister Boris Johnson, has acknowledged that the UK government “failed” the public in its response to the covid-19 pandemic. Cummings was giving evidence to the cross-party health and social care and science and technology committees on 26 May. “The truth is that senior ministers, officials, advisers like me, fell disastrously short of the standards the public has a right to expect of its government in a crisis like this,” said Cummings. “When the public needed us most, we failed. And I’d like to say to all the families of those who have died unnecessarily, how sorry I am for the mistakes that were made, and my own mistakes.” Cummings said the government hadn’t responded quickly enough and was underprepared in the weeks after the coronavirus outbreak was first detected in China in January 2020.

The US, Australia, Japan and Portugal are among countries calling for a more in-depth investigation into the origins of the covid-19 pandemic. On 23 May, the Wall Street Journal reported that three researchers from China’s Wuhan Institute of Virology sought hospital care in November 2019 with symptoms consistent with covid-19. China’s Foreign Ministry and the director of the Wuhan National Biosafety Lab denied the report, and a World Health Organization investigation previously concluded that a laboratory origin of the virus was “extremely unlikely”

Local officials in England “not consulted” over new guidance for areas affected by the B.1.617.2 coronavirus variant

People in England are being advised not to travel into and out of eight areas where the B.1.617.2 coronavirus variant first identified in India is spreading. The updated UK government guidance also says that people in Kirklees, Bedford, Burnley, Leicester, Hounslow, North Tyneside, Bolton and Blackburn with Darwen should avoid meeting people from other households indoors. 

The government has faced criticism over communication of the new advice, which was published on 21 May without an announcement. Blackburn with Darwen council’s director of public health, Dominic Harrison, said local officials in those areas affected “were not consulted with, warned of, notified about, or alerted to this guidance”, Sky News reported on 25 May.
