UK science and medical advisers urge caution on easing of restrictions in England

England’s chief medical officer Chris Whitty cautioned MPs against lifting coronavirus restrictions in England earlier than planned, saying this could increase the size and severity of future surges in infections. “It’s very easy to forget quite how quickly things can go bad if you don’t keep a very close eye on them,” said Whitty. “What we don’t want to do is to accelerate into trouble and then have to reverse straight back out again, open things up and immediately close them down,” he said. “All the modelling suggests there is going to be a further surge.” Whitty was giving evidence to MPs on the commons science and technology committee alongside the UK’s chief scientific adviser, Patrick Vallance. Asked why encouraging data couldn’t lead to an accelerated easing of restrictions, Vallance said that three to four weeks were needed to generate and analyse data, which exceeds the one-week notice that the government wants to give of changes to rules. “I think if you truncate that you are essentially flying blind,” Vallance told the committee.

Greece’s tourism minister Harry Theocharis has said people who are vaccinated against covid-19, have antibodies or test negative for the coronavirus can travel to Greece during the summer of 2021. “All tourists will be subject to random testing,” Theocharis told the ITB Berlin trade show on 9 March. It has been reported that the UK government is considering the possibility of the NHS coronavirus app featuring a digital health passport, which would carry information on vaccinations and test results. UK prime minister Boris Johnson said on 8 March that vaccine passports for international travel will be “a feature of our life in the future”. 

Johnson & Johnson told the European Union it is facing supply issues that could disrupt plans to deliver 55 million doses of its covid-19 vaccine to the bloc in the second quarter of 2021, Reuters reports. The EU has already faced issues related to the supply of other covid-19 vaccines, including those made by Pfizer/BioNTech and Oxford/AstraZeneca. Johnson & Johnson’s vaccine, which consists of a single shot, is expected to be approved by the European Medicines Agency on 11 March and the company has committed to deliver 200 million doses to the EU in 2021.

Temporary Nightingale hospitals built in England during the first wave of covid-19 will be closed in April, the NHS announced. From April, the sites will transition back into locations for local NHS services, with some to be used as testing centres or covid-19 vaccination sites.

Coronavirus deaths

The worldwide covid-19 death toll has passed 2.6 million. The number of confirmed cases is more than 117.2 million, according to Johns Hopkins University, though the true number of cases will be much higher.

Return of pupils is first step in England’s ‘roadmap’ for easing lockdown

Pupils in England began to return to school today for the first time since a national lockdown began in January. Primary schools reopened fully but pupils can return to secondary schools only if they test negative for coronavirus. Most secondary schools are phasing reopening to allow this testing to be done. Since January, most pupils in England have been doing lessons online, with only the children of key workers allowed to physically attend schools. 

The testing of secondary school pupils is being done with the rapid tests known as lateral flow devices. Their use is controversial because they are less accurate than standard PCR tests, and there is a higher risk of false positives and false negatives. Initially, government ministers said pupils who tested positive with a lateral flow test would not be allowed to return to school even if a subsequent PCR test came back negative. Today a spokesperson for the prime minister said pupils could return if a PCR test came back negative. A modelling study released today suggests that the use of lateral flow tests in schools will be beneficial if combined with other measures such as isolating contacts.

The reopening of schools is the first step in the “roadmap” for easing the lockdown in England. On 29 March the government plans to ease restrictions on outdoor meetings and sports, with many businesses being allowed to reopen from 12 April.

Other coronavirus news

New Zealand has increased its order of the Pfizer/BioNTech vaccine to 10 million doses, enough to vaccine the entire population of nearly 5 million people. However, the full order will not arrive until the second half of the year. New Zealand has managed to eliminate the coronavirus but has had occasional outbreaks, including a recent cluster caused by the more transmissible B.1.1.7 variant from the UK. No new cases have been reported since a week-long lockdown in Auckland ended. In February, the country began vaccinating border and quarantine workers.

People in the US who have been vaccinated will be allowed to meet others indoors without wearing masks, and will also not be required to isolate if they are exposed to known covid-19 cases, according to new guidance issued by the US Centers for Disease Control and Prevention. “We know that people want to get vaccinated so they can get back to doing the things they enjoy with the people they love,” said CDC director Rochelle Walensky. The guidance applies to people who are two weeks past the end of their vaccine regimen – which means two doses of the Pfizer/Biontech or Moderna vaccines, or one Johsnon & Johnson shot. However, given that we do not yet know how much vaccines prevent people from catching and transmitting the virus, it is still possible that vaccinated people may infect others. Nearly 10 per cent of the US population has now been vaccinated.

Coronavirus deaths

The worldwide covid-19 death toll has passed 2.59 million. The number of confirmed cases is more than 116.9 million, according to Johns Hopkins University, though the true number of cases will be much higher.

Covid-19 vaccine patents should be waived, says WHO chief

World Health Organization (WHO) director-general Tedros Adhanom Ghebreyesus has said he supports the temporary waiving of covid-19 vaccine patents to enable countries to manufacture and sell vaccine copies at reduced cost. “I don’t believe that globally we’re exercising our full manufacturing muscle at present. For example, some manufacturers have not been able to produce successful vaccine candidates, which is to be expected, but their production facilities could be repurposed for those vaccines that have been proven to work,” he wrote in the Guardian. “Waiving patents temporarily won’t mean innovators miss out. Like during the HIV crisis or in a war, companies will be paid royalties for the products they manufacture.” 

World Trade Organization member states are set to discuss a proposal by India and South Africa next week to waive rules on intellectual property for covid-19 drugs and vaccines. Worldwide, 265 million doses of covid-19 vaccines have been administered, with 80 per cent in just 10 countries, said Mike Ryan, executive director of the WHO’s Health Emergencies Program, during a social media Q&A on 3 March.

Australia has asked the European Commission to review its decision to approve Italy’s blocking of a shipment of covid-19 vaccine doses to the country. In January, the European Commission launched a mechanism to allow monitoring the export of covid-19 vaccines produced in the European Union, and on 4 March Italy blocked a shipment of 250,000 doses of Oxford/AstraZeneca vaccine being sent to Australia. “Australia has raised the issue with the European Commission through multiple channels,” Greg Hunt, Australia’s health minister, told journalists on 5 March. Japan is also concerned about the export ban. The country’s vaccine minister told Reuters: “We want to work with the Ministry of Foreign Affairs to secure the vaccines bound for Japan.” Germany’s health minister expressed concern about the export ban, saying it could disrupt global covid-19 vaccine supply chains.

Willingness to receive a covid-19 vaccine has risen in the UK and globally in recent months, according to a survey on attitudes towards vaccination in 15 countries, conducted by researchers at Imperial College London. In February, 77 per cent of people surveyed in the UK said they would accept a covid-19 vaccine if one was available to them, up from 55 per cent in November. Other countries included in the poll were Australia, Canada, Denmark, France, Germany, Israel, Italy, Japan, The Netherlands, Norway, Singapore, South Korea, Spain and Sweden. Scepticism about the vaccine was highest in France, with only 40 per cent of respondents in February saying they would accept a covid-19 vaccine, although this still represents an increase from 25 per cent in November.

Approval of covid-19 vaccines modified to work against virus variants could be accelerated in the UK

Covid-19 vaccines that have been modified to improve their effectiveness against new coronavirus variants could be fast-tracked for approval in a similar way to annual flu vaccines, according to new guidance from the UK’s medicines regulator. Vaccine manufacturers would need to provide robust evidence that the modified vaccine produces a sufficient immune response, for example release of antibodies into the blood, but wouldn’t need to conduct lengthy clinical trials that don’t add to understanding of the vaccine’s safety and effectiveness. “Our priority is to get effective vaccines to the public in as short a time as possible, without compromising on safety,” said Christian Schneider, chief scientific officer at the UK agency overseeing medicine, in a statement. “The public should be confident that no vaccine would be approved unless the expected high standards of safety, quality and effectiveness are met,” he added. Several manufacturers of covid-19 vaccines are already working on tweaking them to tackle coronavirus variants.

The B.1.1.7 coronavirus variant first identified in the UK is between 43 and 90 per cent more transmissible than the original virus, a study published in the scientific journal Science has estimated. “Without stringent control measures, including limited closure of educational institutions and a greatly accelerated vaccine roll-out, covid-19 hospitalisations and deaths across England in 2021 will exceed those in 2020,” the authors of the study write in their paper, adding that the spread of the variant at similar rates in other countries, including Denmark, Switzerland and the US, is “concerning”.

The European Medicines Agency (EMA) has announced a rolling review of the Sputnik V covid-19 vaccine developed in Russia. The Sputnik V vaccine prompted concern among immunologists last year after it was approved in Russia in August before any detailed results from advanced clinical trials were released. But in early February, interim results from a phase III trial indicated the vaccine is 91.6 per cent effective at preventing symptomatic covid-19. World Health Organization Europe director Hans Kluge told a press briefing on 4 March that the EMA’s announcement was a “welcome development”, adding that: “[in Europe] we desperately need to enlarge our portfolio of vaccines”. 

Italy has blocked a shipment of 250,000 Oxford/AstraZeneca covid-19 vaccine doses to Australia. In January, the European Commission launched a mechanism to enable monitoring of covid-19 vaccines produced in Europe and being exported out of the European Union. 

The rate of covid-19 Infections in England is shrinking less quickly than it was earlier in 2021, according to recent results from the REACT study by researchers at Imperial College London. The study indicates one in 204 people were infected between 4 and 23 February, down only slightly from one in 196 during the period between 4 and 13 February, suggesting the fall in infections seen since January has slowed.

Germany is expected to approve the Oxford/AstraZeneca covid-19 vaccine for use in people over the age of 65.

US to have enough covid-19 vaccines for all adults by end of May

US president Joe Biden announced the US is on track to have enough covid-19 vaccine doses to vaccinate its entire adult population by the end of May. “Great news, but stay vigilant,” said Biden. “It’s not over yet,” he added. More than 76 million people in the US have received a first dose of covid-19 vaccine so far equivalent to about 23 per cent of the population. Not all adults will be vaccinated by the end of May, as the vaccines will take time to administer, but the country is on track to meet Biden’s target of delivering 100 million doses in his first 100 days in office. 

The governor of Texas, Greg Abbott, announced that the state will lift its requirement for people to wear face coverings and will allow businesses to reopen at full capacity next week. This is in contrast to advice from the US Centers for Disease Control and Prevention, which on 1 March warned of a potential fourth surge of cases before the majority of people in the country are vaccinated.

A preliminary study led by researchers at the University of Bristol, UK, indicates that a single dose of the Pfizer/BioNTech or Oxford/AstraZeneca vaccine reduces the risk of hospitalisation with covid-19 by about 80 per cent among people aged 80 and over. The results add to earlier findings from an analysis by Public Health England, which found that a single dose of either vaccine is 80 per cent effective at preventing hospitalisation among people over 80. “This adds to growing evidence showing that the vaccines are working to reduce infections and save lives,” Mary Ramsay, Public Health England’s head of immunisation, told the BMJ

Austria will receive an additional 100,000 doses of the Pfizer/BioNTech covid-19 vaccine to administer to all adults in the Schwaz district of the Tyrol province, where there are currently 66 active cases of people infected with the B.1351 coronavirus variant first identified in South Africa.

Deaths from covid-19 in England and Wales are falling quickest among people over 80

Covid-19 deaths in England and Wales are falling fastest among people aged 80 and over, figures from the Office for National Statistics (ONS) suggest, indicating that the vaccination programme has had an impact on deaths from the disease. People aged 80 and over were included in the top four priority groups for covid-19 vaccination. According to analysis of ONS data by the Guardian, 1622 people aged 80 and above were reported to have died from covid-19 in the week up to 19 February, down from 5300 four weeks earlier and equivalent to a reduction of 69 per cent. Among people aged between 70 and 79, there was a reduction in covid-19 deaths of 65 per cent over the same period, and the equivalent figure was 55 per cent for people aged 0 to 69. 

“Together with the evidence for reduction of hospitalisations after both the Pfizer/BioNTech and the Oxford/AstraZeneca vaccines, the message is clear: vaccines work for those 80+ and 70+ and they are saving lives,” said Zania Stamataki at the University of Birmingham in a statement

More than 20.2 million people in the UK as a whole had received a first dose of covid-19 vaccine as of 1 March.

The search for a person who tested positive for the P.1 variant of coronavirus in England has been narrowed down to 379 households in the south-east of the country, UK health minister Matt Hancock told parliament on 2 March. Six cases of the P.1 coronavirus variant, first detected in people travelling from Brazil to Japan, have been identified in the UK. “We’re grateful that a number of potential cases have come forward,” said Hancock.

Germany is expected to start easing some coronavirus restrictions from 8 March. Under new draft rules, a maximum of five people from two households would be allowed to meet. Currently, meetings are restricted to a maximum of two people. Some shops and salons would also be allowed to reopen. The draft plans for easing measures will be discussed by national and state government leaders on 3 March.

A World Health Organization (WHO) panel is advising against the use of the malaria drug hydroxychloroquine to treat covid-19 patients.

Health officials in England attempt to trace person infected with P.1 virus variant

Efforts are underway in England to trace a person infected with the P.1 coronavirus variant, after they used a home testing kit but didn’t complete a registration form. The P.1 variant was first identified in people who were travelling from Brazil to Japan on 10 January, and the infected person is one of six cases of the P.1 variant detected in the UK in February. Three of the six cases were detected in England and the remaining three in Scotland. Public health officials are appealing for anyone who hasn’t yet received a result from a test on 12 or 13 February to come forward by calling 119. Since 15 February, travellers arriving in England from 33 countries – including Brazil – have been required to quarantine in a hotel for 10 days. In Scotland, the hotel quarantine rule applies to all international arrivals.

UK prime minister Boris Johnson said the government has no intention to reverse its plans to ease coronavirus restrictions in England. “Our whole strategy is to go forward in a way that is cautious but irreversible. And we don’t think that there’s any reason on this basis to change that now,” he told journalists on 1 March. Under the government’s current plans, schools in England are expected to reopen on 8 March. To support this planned reopening of schools, the government has said that families with children in school will be able to test themselves for coronavirus twice a week from home, free of charge.

Across the UK, more than 20 million people have received a first dose of a covid-19 vaccine.

One dose of Pfizer vaccine shows 75 per cent reduction in asymptomatic infections

There is yet more good news on vaccine effectiveness. A study based on nearly 9000 coronavirus tests done on healthcare workers in Cambridge, UK, has found that asymptomatic infections fell by 75 per cent 12 days after they got one dose of the Pfizer/BioNTech vaccine. There was a similar reduction in symptomatic infections.

The finding is significant because it shows the vaccine will greatly reduce the spread of the virus. It was already clear from clinical trials and previous studies that the Pfizer vaccine is highly effective at preventing symptomatic infections but we did not know how many vaccinated people might still get infected without symptoms and potentially pass the disease on to others.

“This will mean a substantial reduction in transmission of the virus as more and more people are vaccinated, which is really great news,” study leader Mike Weekes at the University of Cambridge, told the Guardian.

Fifty million Covid-19 vaccine doses have been given to people in the US since President Joe Biden took office 37 days ago, taking the total to around 67 million. Biden had promised to deliver 100 million doses in his first 100 days, so his administration is on course to comfortably beat this target. But he warned that things will not return to normal soon. “This is not a victory lap. Everything is not fixed. We have a long way to go. And that day when everything is back to normal depends on all of us,” Biden said.

New Zealand has reported one more locally acquired case of coronavirus. The infected person went to work at a fast food restaurant on Monday despite being told to isolate at home. But officials say the small cluster of cases in Auckland is under control, and have not imposed another lockdown on the city. “This is a situation where we know the source of the cases [and] we know where there may have been contact with others,” said Prime Minister Jacinda Ardern.
