The Omicron variant of coronavirus is less likely to cause long Covid than previous variants, according to the first peer-reviewed study of its kind from the UK. Researchers at King's College London, using data from nearly 100,000 people who logged their Covid symptoms via an app, found the odds of developing long Covid after infection were 20 per cent to 50 per cent lower during the Omicron wave in the UK compared to Delta. The figure varied depending on the patient's age and the timing of their last vaccination. Long Covid, which includes prolonged symptoms ranging from fatigue to 'brain fog', can be debilitating and continue for weeks or months. It is increasingly being recognised as a public health problem, and researchers have been racing to find out if Omicron presents as big a risk of long Covid as previously dominant variants. The study from King's is believed to be the first academic research to show Omicron does not present as great a risk of long Covid, but that does not mean long Covid patient numbers are dropping, the team said. While the risk of long Covid was lower during Omicron, more people were infected, so the absolute number now suffering is higher. "It's good news, but please don't decommission any of your long Covid services," lead researcher Dr Claire Steves said, appealing to health-service providers.

The National Health Service will begin its autumn Covid vaccine program next week, a month earlier than planned in response to the spread of a new variant dubbed Pirola. Covid vaccines will be administered to care home residents and housebound individuals from Monday onwards, while over-65s and other vulnerable groups will receive their appointments the week after. On Aug. 30, NHS England shifted the autumn vaccination drive to start on September 11 in response to the new Covid-19 variant, BA.2.86, detected on August 18. The primary groups can book through a national system upon receiving an invitation from the NHS. Some people may get an earlier call from their GP, and a few have already scheduled Covid vaccinations alongside their flu jabs. The NHS will begin inviting other eligible groups from Sept. 18. However, it is important to note that not everyone will receive a call at the same time. These groups will include individuals aged 65 and over, those aged six months to 64 years in a clinical risk category, frontline health and social care workers, and individuals aged 12 to 64 who are carers or household contacts of those with immunosuppression.

The prevalence of Covid-19 infections in England rose to around one in 60 people in the week ending November 27, the Office for National Statistics said today (December 03), led higher by the dominant Delta variant rather than the newly identified Omicron. The prevalence was up from one in 65 reported the previous week, the ONS said, adding that 99 per cent of all coronavirus infections which were sequenced were genetically compatible with the Delta variant. "To date, we have not identified any infections compatible with the new Omicron variant (B.1.1.529) among our survey participants," the ONS said. Prime Minister Boris Johnson has introduced travel restrictions and some mask mandates, with a view to slowing the spread of Omicron while work is undertaken to understand it better. There have been 42 confirmed cases of the variant in Britain, which has mutations consistent with reduced vaccine efficacy.

The National Institute for Health and Care Excellence (NICE) has issued draft guidance on 'Evusheld' which is not recommended for vulnerable adult with high risk of severe Covid-19 on Thursday (16 February). The draft guidance is open for public consultation until 9 March 2023. The committee will consider any comments received at a meeting currently due to take place on 4 April 2023. It comes after last month's decision by the US drug regulator to withdraw its emergency use authorisation for Evusheld as a preventative treatment for Covid-19, which said there was insufficient evidence that Evusheld is effective against the dominant variants of Covid-19 in the US. NICE's independent appraisal committee has reached the same conclusion having considered evidence which shows Evusheld is unlikely to prevent infection with most of the variants circulating in the UK now and in the near future. It has also announced that it is developing a new review process to update recommendations on the cost-effectiveness of Covid-19 treatments so they can be made available more quickly to patients if they show promise against new variants and are found to be cost-effective.

The Medicines and Healthcare products Regulatory Agency (MHRA) has approved a second "bivalent" vaccine as a Covid-19 booster. The updated booster vaccine made by Pfizer/BioNTech, targeting two coronavirus variants, has been approved for use in individuals aged 12 years and above. In each dose of the booster vaccine, 'Comirnaty bivalent Original/Omicron', half of the vaccine (15 micrograms) targets the original virus strain and the other half (15 micrograms) targets Omicron (BA.1). Dr June Raine, MHRA chief executive said: "I am pleased to announce that we now have a second approved vaccine for the UK Autumn booster programme. The clinical trial of the Pfizer/BioNTech bivalent vaccine showed a strong immune response against the Omicron BA.1 variant as well as the original strain. Bivalent vaccines are helping us to meet the challenge of an ever-evolving virus, to help protect people against Covid-19 variants. We have in place a comprehensive safety surveillance strategy for all UK-approved Covid-19 vaccines, and this will include the updated booster we approved today."

Two new subvariants of Omicron - BA.4 and BA.5 - are spreading much faster than other corovanirus variants in Europe, which could lead to more hospitalisations and deaths as they become dominant, the EU's disease prevention agency said on Monday (June 13). Most EU countries have so far detected low rates of the two subgroups. But in countries where the proportion has risen - such as Portugal, where BA.5 accounted for 87 per cent of cases by May 30 - there have been surges in overall cases, according to the European Centre for Disease Prevention and Control (ECDC). The two sublineages were added to the World Health Organization's monitoring list in March and have also been designated as variants of concern by the ECDC. Variants BA.4 and BA.5 do not appear to carry a higher risk of severe disease than other forms of Omicron.But an increase in case numbers from higher transmission rates risks leading to an increase in hospitalisations and deaths, the agency said. "The growth advantage reported for BA.4 and BA.5 suggest that these variants will become dominant," ECDC said in a statement on its website.

The World Health Organization says it is tracking a few dozen cases of two new sub-variants of the highly transmissible Omicron strain of the coronavirus to assess whether they are more infectious or dangerous. It has added BA.4 and BA.5, sister variants of the original BA.1 Omicron variant, to its list for monitoring. It is already tracking BA.1 and BA.2 - now globally dominant - as well as BA.1.1 and BA.3. The WHO said on Monday (April 11) it had begun tracking them because of their "additional mutations that need to be further studied to understand their impact on immune escape potential". Viruses mutate all the time but only some mutations affect their ability to spread or evade prior immunity from vaccination or infection, or the severity of disease they cause. For instance, BA.2 now represents nearly 94% of all sequenced cases and is more transmissible than its siblings, but the evidence so far suggests it is no more likely to cause severe disease.

The Royal Pharmaceutical Society (RPS) has cautioned that measures to protect people against Covid-19 must be stepped up in the wake of discovery of the new variant, B.1.1.529. It has urged members of the public to practice 'hands, face, space and ventilation' protection measures which have become less used in the last few months. RPS director of pharmacy Robbie Turner said that though it was too early to conclude about the transmissibility or resistance of the new variant to current vaccines, quick action should be taken to protect the public. "Each one of us must take the necessary precautions of wearing a mask in higher risk situations, maintaining social distancing wherever possible, ensuring there's appropriate ventilation indoors when meeting others and washing our hands regularly." Encouraging people to take Covid vaccine, he said, it "is still our best defence against this virus".

England won't have any new Covid-19 restrictions before the end of 2021, health secretary Sajid Javid said on Monday (December 27) whilst the government awaits more evidence on whether the NHS can cope with high infection rates in the new year. "There will be no further measures before the new year," Javid told reporters, adding: "When we get into the new year, of course we will see then whether we do need to take any further measures." He said that the highly transmissible Omicron variant of the virus now accounted for around 90 per cent of cases across England and urged people to celebrate New Year cautiously. The government's attention is focused on the number of patients being hospitalised with Omicron after early data last week suggested the variant carried a lower risk of admission. The latest data showed the number of patients in hospital in England with Covid-19 was its highest since March, at 8,474, but a long way off peaks above 34,000 in January. A combination of factors, including Britain's vaccination programme, the lag between infections and hospitalisations and the potentially less harmful effects of the Omicron variant have all been put forward by health experts as possible explanations for lower numbers.

Britain has started counting possible Covid-19 reinfections in its daily coronavirus data, changing its approach to reflect the increased number of people catching the disease for a second time as the Omicron variant predominates. The UK Health Security Agency (UKHSA) added around 840,000 cases to the cumulative total, taking it to 17.3 million coronavirus infections reported. Britain's daily Covid statistics previously would only count people who had tested positive for the first time to avoid double-counting people who had received multiple positive test results for the same infection. However, with variants such as Omicron leading to an increase in reinfections, the UKHSA said it would change its method to treat positive tests as separate infections if there was at least 90 days between test results. The change took effect on Monday (January 31). "Reinfection remained at very low levels until the start of the Omicron wave. It is right that our daily reporting processes reflect how the virus has changed," said Steven Riley, UKHSA's Director General of Data and Analytics.

Deviating from the initial schedule to kick off the flu and Covid-19 vaccination campaigns in October, the NHS England has announced that the autumn vaccination drive will commence sooner than expected in England, starting on September 11. This decision was taken as a precaution in response to a new Covid-19 variant. The precautionary measure is being taken as the Department of Health and Social Care and the UK Health Security Agency examined the variant BA.2.86, which was first detected in the UK on Friday, August 18, 2023, the NHSE said on Aug. 30. While NHS England had previously announced that vaccinations for both NHS programmes would begin on October 2 for residents of older adult care homes, appointments for other eligible groups were scheduled for the following week, starting on October 7. This decision prompted community pharmacy leaders to denounce the delayed start of the flu service as 'unacceptable'.

The NHS on Sunday (January 30) expanded its Covid-19 vaccination programme to include vulnerable children aged five to 11 years. Eligible children include those with diabetes, immunosuppression, learning disabilities, and other conditions as outlined by the UK Health Security Agency in the Green Book. Additionally, children living with someone immunosuppressed will be eligible to get the first dose of the Covid-19 vaccine in line with advice issued by the Joint Committee on Vaccination and Immunisation (JCVI). According to the NHS, there are around 500,000 eligible children in the latest cohort. GP and deputy lead for NHS vaccination programme Dr Nikki Kanani, said: "We know vaccines give significant protection against severe illness from Covid - including the omicron variant, so it is important that our youngest and most at-risk get protected.

British drugmaker AstraZeneca says it's confident that its new version of COVID-19 antibody treatment could protect immunocompromised patients against all known virus variants. Laboratory studies show the antibody, called AZD3152, neutralises all known variants of COVID-19 and AstraZeneca has support from regulators to make the treatment available by the end of this year, the company's vaccines head Iskra Reic said on Tuesday (April 18). AstraZeneca plans, pending more positive data and regulatory approval, to make the antibody available by the end of 2023. These types of therapies are most needed for people with compromised immune systems, either because of underlying conditions or because they are undergoing immune suppressing treatments. They account for nearly 2% of the global population. AstraZeneca's AZD3152, it new COVID-19 antibody, was acquired through a $157 million deal last year with British biotech start-up RQ Bio. The British drugmaker will likely make future investments like its current partnerships with RQ Bio but did not have any deals to announce, said Reic, a long-time AstraZeneca executive who has led the company's vaccines and immune therapies unit since it was formed in late 2021, during the pandemic.

Health secretary Sajid Javid urged people to book a Covid-19 booster shot on Wednesday (December 1) as he said there were 22 confirmed cases of the Omicron virus variant in the country. Javid said the government believed a booster campaign would help protect against severe disease from Omicron, even if it turns out that vaccines are not as effective against the variant as previous strains of the disease. He said he hoped to know more about Omicron within two weeks, as scientists work to understand what impact the new variant will have on transmissibility and serious disease. "At this point in time the case numbers are very low," Javid told Sky News. "For the UK we've got 22 confirmed cases at the moment and that will go up, it will certainly go up." Britain plans to offer all adults a Covid-19 booster shot by the end of January. Government data shows 81 per cent of the population aged over 12 have had two doses of the vaccine while 32 per cent have had a booster shot or third dose.

The NHS on Sunday (January 30) expanded its Covid-19 vaccination programme to include vulnerable children aged five to 11 years. Eligible children include those with diabetes, immunosuppression, learning disabilities, and other conditions as outlined by the UK Health Security Agency in the Green Book. Besides, children living with someone immunosuppressed will be eligible to get the first dose of the Covid vaccine in line with advice issued by the Joint Committee on Vaccination and Immunisation (JCVI). According to the NHS there are around 500,000 eligible children in the latest cohort.

British drugmaker GSK said on Tuesday (December 7) its antibody-based Covid-19 therapy with US partner Vir Biotechnology is effective against all mutations of the new Omicron coronavirus variant, citing new data from early-stage studies. The data, yet to be published in a peer-reviewed medical journal, shows that the companies' treatment, sotrovimab, is effective against all 37 identified mutations to date in the spike protein, GSK said in a statement. Last week, another pre-clinical data showed that the drug had worked against key mutations of the Omicron variant. Sotrovimab is designed to latch on to the spike protein on the surface of the coronavirus, but Omicron has been found to have an unusually high number of mutations on that protein. "These pre-clinical data demonstrate the potential for our monoclonal antibody to be effective against the latest variant, Omicron, plus all other variants of concern defined to date by the WHO," GSK chief scientific officer Hal Barron said.

The NHS Confederation has urged the government to reconsider its 'living with Covid' plan and introduce mitigating actions that will help avoid further critical incidents being declared at the NHS front-line. The organisation said the high rates of Covid is having a major impact on the delivery of health services and slowing down efforts to reduce large waiting lists, noting that the country has been in the grip of another spike in Covid cases resulting from the Omicron BA.2 variant. With more than 20,000 patients now in hospital with Covid (or who have Covid but are in hospital for other reasons) and high staff absences, NHS is facing huge operational challenges, harming efforts to reduce waiting times in other areas, it said.

GlaxoSmithKline and Sanofi said on Wednesday (December 15) they expect data from late-stage clinical trials of its booster dose of their Covid-19 vaccine candidate in the first quarter, instead of this year, another delay for the potential shot. The news came as two companies said preliminary data from trials showed the single-dose booster provided strong immune responses. They added that they need more time to test the booster on more people who have not been infected by the virus before they can submit data to regulators. The Phase III trial for the recombinant adjuvanted Covid-19 vaccine recruited most participants in the third quarter, coinciding with a significant increase in the number of people infected globally due to the Delta variant, it said. "To provide the necessary data to regulatory authorities for the booster vaccine submission, the trial will continue to accrue the number of events needed for analysis, with results expected in Q1, 2022." No safety concerns were identified. This is the latest delay for the vaccine's development, putting the companies further behind rivals in the race for Covid-19 shots.

More than 7,000 hospitalisations and deaths in the UK could have been averted in summer 2022 if people had received their recommended COVID-19 vaccine doses, a new study published in The Lancet has revealed. The largest ever study carried out in the UK found that between a third and a half of the UK population had not had the recommended number of COVID vaccinations and boosters by summer 2022. In Northern Ireland, nearly 50 per cent of the population were under-vaccinated, while the proportion of under-vaccinated people in England was 45.7 per cent, 34.2 per cent for Scotland and 32.8 per cent Wales. Researchers from the Health Data Research UK (HDR UK) and the University of Edinburgh analysed the electronic health records of 67 million residents aged 5 and older from across the four countries during June 1 to September 30 2022.

Britain will offer a Covid-19 booster shot to all adults and could halve the dose interval for booster jabs from six to three months in a bid to accelerate its vaccination programme amid concern over the new Omicron coronavirus variant, as number of new cases found in the country rise. The move, backed by a scientific advisory body and Health Secretary Sajid Javid, comes as ministers scramble to react swiftly to the new variant, which was first detected in South Africa. Prime minister Boris Johnson has responded to the emergence of Omicron by making mask-wearing compulsory in shops and on public transport in England. Until now, only adults in the UK aged 40 and above were eligible for a booster dose six months after their last. But that timeframe will now be halved to three months, alongside the programme's expansion to all over-18s, with priority given to older people. "These measures will protect more people, more quickly and make us better protected as a nation," Javid told MPs.
