Pfizer vaccine is 95 per cent effective overall and protects 94 per cent of people over Further data about the coronavirus vaccine being developed by US pharmaceutical company Pfizer and German biotechnology company BioNTech shows that it is 95 per cent effective for all age groups, and protects 94 per cent of adults over The new data, from the first set of complete from the phase III trial, also showed that the vaccine produced no serious side effects.
Pfizer and BioNTech said they will submit a request for emergency use authorisation to the US Food and Drug Administration within days, which will allow the vaccine to be used with people outside the trial. About 40, people participated in the trial, with half receiving two doses of the vaccine and the other half a placebo.
Out of covid cases among trial participants, only eight were in the vaccinated group, the companies said in a statement. The are encouraging because older individuals are at an increased risk of becoming severely ill and dying from covid, in part because the immune system weakens with age. The vaccine is based on similar mRNA technology to that used in the vaccine candidate being developed by US biotechnology company Moderna, which was found to be almost 95 per cent effective based on a preliminary analysis.
The Pfizer-BioNTech trial will continue to collect data on the safety and effectiveness of the coronavirus vaccine for a further two years. A preliminary study suggests the majority of people who have recovered from covid may still have coronavirus-specific immune cells in their bodies more than six months after infection. The study, which has not been published or peer-reviewed, included 41 people who had tested positive for the coronavirus at least six months prior. It found that levels of coronavirus-specific T-cells had only decayed slightly at six months, while other antibody-producing immune cells called B-cells actually increased between one and six months after infection.
Doctors in Switzerland said intensive care beds are at full capacity in the country. All of the certified intensive care unit beds in Switzerland are occupied, the Swiss Society for Intensive Medicine said in a statement yesterday.
It also advised vulnerable people to write down in a will whether they would like to receive life support in the event that they become severely ill. Switzerland recorded a daily average of coronavirus cases in the week leading up to 17 November. The worldwide covid death toll has passed 1. The of confirmed cases is more than Will vaccines stop the pandemic? There were deaths from coronavirus in England and Wales in the week ending 6 November, according to the latest s from the Office for National Statistics. The of people who died was more than the week, which saw deaths.
It is the second consecutive week with more than deaths involving the coronavirus across the two nations. These latest s do not reflect the potential impact of new lockdown measures in England and Wales. It may take several weeks for the effects of these measures to appear in official death registration data, said Kevin McConway at the Open University in a statement. There have been some concerns about how the vaccine would be stored and distributed , given its ultra-low temperature formulation. UK prime minister Boris Johnson has tested negative for the coronavirus, his spokesperson told journalists today.
Coronavirus vaccines : How do mRNA coronavirus vaccines work? Science with Sam explains. Moderna vaccine : Early suggest the Moderna vaccine is even more effective than the Pfizer vaccine, including in older people, boosting hopes that we might end up with several vaccines against covid A Moderna covid vaccine study participant gets a coronavirus nose swab test in Miami.
A coronavirus vaccine candidate being developed by the pharmaceutical company Moderna appears to be nearly 95 per cent effective , according to early trial released by the company today. The vaccine candidate is in phase III trials involving more than 30, people in the US, half of whom received a placebo.
The interim analysis found 95 cases of covid among trial participants, only five of which were among the vaccinated group. None of the cases among vaccinated individuals were classed as severe, compared to 11 in the placebo group. The vaccine is based on similar mRNA technology to that used in the vaccine being developed by Pfizer and BioNTech , which was found to be more than 90 per cent effective based on a preliminary analysis. Moderna said it intends to submit for an emergency use authorisation with the US Food and Drug Administration and global regulatory agencies in the coming weeks.
The company expects to have approximately 20 million doses of the vaccine ready to ship in the US by the end of this year, and said it remains on track to manufacture between million and 1 billion doses globally in Moderna has agreed to provide the US with million doses of the vaccine, with an option to buy a further million.
The European commission has a potential purchase agreement with the company for between 80 million and million doses, as part of the EU covid vaccine scheme. The UK decided not to participate in the EU vaccine purchase scheme and does not have any pre-existing purchase agreement with Moderna. Coronavirus case s in the US have jumped by a million in only a week. The country has now reached a total of more than 11 million cases since the start of the pandemic, just six days after reaching the grim milestone of 10 million.
As of yesterday, more than 69, people across the US were in hospital with covid — the highest yet. A growing of states, including Washington and Michigan, have reimposed stay-at-home orders and other restrictions. Meanwhile, US president Donald Trump has reportedly blocked the White House coronavirus taskforce from communicating with a separate team assembled by president-elect Joe Biden. UK prime minister Boris Johnson and several other members of Parliament are self-isolating after an MP at a meeting they attended on Thursday tested positive for the coronavirus.
Johnson had covid in April and was hospitalised, before recovering. Covid and population size : A pandemic assisted by our incursions into nature has given questions about human population size a renewed focus, but advocates for limiting population also have questions to answer.
A nurse preparing dexamethasone for treatment. One in four coronavirus patients in the UK are missing out on life-saving dexamethasone treatment. Researchers calculated that failure to give the treatment had led to 55 deaths. Dexamethasone is a steroid and the only known drug that reduces deaths from the coronavirus. It works by suppressing an overreaction of the immune system that can cause damaging inflammation of the lungs and other organs.
In June a UK trial showed that dexamethasone reduces the death rate of covid by a third in people who are on ventilators and by one fifth in those who are receiving supplementary oxygen by other means. A consortium of UK researchers tracked the treatments given to people in hospital with covid since then. The of people who received the steroid rose over time. But even in August and September, it was not being given to all those who met the criteria — though it is unclear why. The other main treatment for the coronavirus, the antiviral agent remdesivir, has had a vote of no confidence from the head of the European Society of Intensive Care Medicine.
The move comes after the largest trial of the drug found it has little or no impact on death rates. However other smaller studies suggest remdesivir does speed up recovery from the infection. Covid infections in England are still rising, although the rate of increase most recently has become slower than in the preceding weeks, according to the latest data from the Office of National Statistics released today.
The highest infection figures are in teenagers and young adults. The of positive tests are also rising in Wales and Scotland. In Northern Ireland the trend seems to have levelled off. People with learning disabilities have died from covid at higher rates than the rest of the population, according to a report from Public Health England.
In the age group, people with learning disabilities had a death rate thirty times higher. The authors of the report say this could be because people in this group are more likely to be overweight and have diabetes than people outside this group. The charity Mencap told the BBC the government has failed to protect a vulnerable group. Researchers who work with the coronavirus are testing positive for the virus even though they do not seem to be infected.
Older teenagers should not be lumped in with younger children in terms of their likelihood of catching the coronavirus, says a UK paediatrician. The latest case figures from Scotland show that year-olds have a similar infection rate as middle-aged adults, while figures for everyone under 15 are much lower. The of confirmed cases is more than 53 million, according to Johns Hopkins University , though the true of cases will be much higher.
We must now avoid creating a self-fulfilling prophecy. Shoppers in Wimbledon, London before the second UK national lockdown. Since then, though, new infection s may have started to plateau or fall, according to a different survey based on people using the Covid Symptom Study app. This has placed the current reproduction R below 1, at 0. However, this survey can only report from people who have chosen to download and use the app, so the figures may not be as representative as the REACT-1 study.
Hospital workers in England will soon start being screened for the coronavirus, whether or not they have symptoms of infection, according to Health Service Journal. Staff who interact with patients will be asked to test themselves twice a week before coming into work.
Antigen-based test kits will be sent out to the first 34 trusts this week, but the scheme will switch to more sensitive rapid genetic tests later this year, as it is rolled out more widely. The of people in England waiting more than a year for surgery or hospital treatment has shot up due to the pandemic.
By September this year the of those who had waited that long stood at nearly , people compared with around in September , according to NHS England. When the UK first went into lockdown in March, nearly all routine appointments and operations were deferred, and hospitals have been trying to catch up ever since.
The explanation for why children are less likely to catch covid may be a recent brush with a related coronavirus that causes colds. According to a UK study , 43 per cent of children had antibodies to such a virus, compared with 5 per cent of adults. About one in five colds among children are caused by a coronavirus. Why social distancing is hard : Hugs, handshakes and air kisses serve the same crucial purposes as animal greetings like sniffing, eye poking and buttock grabbing. The European Union has made a deal to buy up to million doses of the Pfizer and BioNTech coronavirus vaccine candidate.
The bloc will be able to purchase million doses initially, with an option to buy another million. Russian authorities said their Sputnik V coronavirus vaccine candidate is 92 per cent effective at protecting people from covid The are derived from a much smaller of coronavirus infections compared to those from the Pfizer vaccine trial. The early analysis of Sputnik V was based on 20 trial participants out of 16, being diagnosed with covid, ificantly fewer than the 94 cases in the Pfizer and BioNTech trial. Pfizer said it would continue its phase III trial until there were at least coronavirus cases, to confirm how well it works.
The US recorded more than a million new coronavirus cases in the first 10 days of November. Several states reported record daily increases in new cases yesterday, including about 12, in Illinois, 10, in Texas and in Wisconsin. The US as a whole also reached a record of hospitalisations yesterday, with more than 61, people currently in hospital with covid, according to the COVID Tracking Project. University students in England will be given a six-day window between 3 and 9 December to travel home before the Christmas holidays, with coronavirus tests to be carried out before they leave campus.
Under the new plans, announced by the Department for Education yesterday, students who test positive would need to self-isolate for 10 days. Coronavirus in animals : Mink are the latest animal to get infected with covid, risking the prospect of a dangerous mutation that could pass back to humans. While the threat is small, there are many reasons that animals catching the coronavirus is bad news. Pfizer vaccine : We may have a coronavirus vaccine that works, but can we keep it cold enough to deliver it to millions of people?
A volunteer is injected with a vaccine as he participates in a coronavirus vaccine study at the Research Centers of America, in Hollywood, Florida. About 36 per cent of people in the UK and 51 per cent in the US report being either uncertain or unlikely to agree to be vaccinated against the coronavirus, should a vaccine become widely available, according to a report by two UK scientific institutions. Uptake of a future coronavirus vaccine would need to be 80 per cent or higher in order to protect communities, assuming the virus was spreading with an R of around 2.
The report also said that officials must manage public expectations for a transition period during which the use of face coverings and social distancing are still encouraged, even after the first vaccines are available.
It recommended that health and care workers should be given priority for receiving a potential vaccine. People in other high-risk occupations should also be prioritised, according to the report, including teachers, bus drivers and retail workers, as well as vulnerable groups in crowded situations, such as the homeless and people in prisons. The authorisation, announced by the FDA yesterday, applies to people who test positive and are at risk of developing a severe form of covid or being hospitalised for the condition. The FDA said it only applies to people above age 12 who are newly infected, and should not be used in people already hospitalised for covid Doses of the drug are limited, however — in a statement Eli Lilly said it expects to have enough doses to treat up to one million people by the end of the year.
A phase III trial of a coronavirus vaccine candidate being developed by Chinese company Sinovac Biotech has been suspended. This is standard procedure in vaccine development , and allows time for researchers to determine the cause of the illness and ensure the safety of participants in the trial. Rapid coronavirus tests being trialled in Liverpool will also start to be rolled out in other UK cities , including London, Manchester, Birmingham, Newcastle, Nottingham and Bristol, according to the UK government. The worldwide death toll has passed 1. Pfizer coronavirus vaccine : Pfizer and its partner BioNTech say their coronavirus vaccine is 90 per cent effective in phase III trials.
How excited should we be about the news, and what questions remain unanswered? Pfizer said that an early analysis of the from the phase III trial found more than 90 per cent fewer symptomatic coronavirus cases among trial participants who received two doses of the vaccine candidate three weeks apart compared to those who received a placebo. So far in the trial, 38, people have received two doses of either vaccine or placebo as of 8 November, and there have been 94 confirmed coronavirus cases in total among them. The have not been peer-reviewed or published in a scientific journal, and Pfizer said further analysis will occur once there have been confirmed coronavirus cases among the participants.
Pfizer is developing the vaccine in partnership with German biotechnology company BioNTech. Pfizer said it plans to submit an application for emergency use authorisation to the US Food and Drug Administration after collecting and analysing additional data on efficacy and safety, which it expects will occur in the third week of November.
If authorised, the company said up to 50 million doses of the vaccine could be available globally by the end of the year and 1. The UK has already ordered 40 million doses of the vaccine candidate and expects to have 10 million doses available by the end of the year if regulators approve it, a spokesperson for UK prime minister Boris Johnson told Reuters. There have been more than 50 million coronavirus cases confirmed globally, according to Johns Hopkins University, and more than 1. Reuters analysis suggests a second wave of the virus in the past 30 days ed for a quarter of the total confirmed cases.Sub masc Hayward seeking total top
