The UK Health Security Agency on Friday said it had designated a sub-lineage of the dominant and highly transmissible Omicron coronavirus variant as a variant under investigation. BA.2, which does not have the specific mutation seen with Omicron that can be used as a proxy to easily distinguish it from Delta, is being investigated but has not been designated a variant of concern. "It is the nature of viruses to evolve and mutate, so it's to be expected that we will continue to see new variants emerge," Dr Meera Chand, incident director at the UKHSA, said. "Our continued genomic surveillance allows us to detect them and assess whether they are significant." Britain had identified 53 sequences of the BA.2 sub-lineage as of January 10, with updated figures due to be published later on Friday.

There is no sign of a surge of the Omicron coronavirus variant in Britain so far, the chief of the UK Health Security Agency said on Tuesday, adding that there was no rise in the proportion of tests with a quirk that distinguishes it from Delta. Jenny Harries said there were five confirmed Omicron cases in England and 10 "highly likely" cases, but that was not a sign of an increase in "S-gene target failure" in PCR tests in Britain, which is a feature of Omicron. "Right across the country we watch for… S-gene target failure, which is a sort of proxy measure," Harries told BBC radio. Cases with S-gene target failure can then be prioritised for full genomic sequencing.

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 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 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.

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.

The British scientist who led the research underpinning AstraZeneca's coronavirus vaccine said at the weekend that a new jab could be developed against the emerging Omicron variant "very rapidly" if needed. Professor Andrew Pollard, director of the Oxford Vaccine Group, also said existing vaccines should work against the new strain, but that would only become apparent after more research in the coming weeks. "It's extremely unlikely that a reboot of a pandemic in a vaccinated population like we saw last year (with the Delta variant) is going to happen," he told BBC radio. But if required, "The processes of how one goes about developing a new vaccine are increasingly well-oiled, so if it's needed that is something that could be moved very rapidly." In a statement, AstraZeneca said it had "developed, in close collaboration with Oxford University, a vaccine platform that enables us to respond quickly to new variants that may emerge".

The 21st edition of the Pharmacy Business Awards have been postponed due to a dramatic rise in the number of Omicron cases nationwide in recent months. The in-person event - initially scheduled to be held on February 3 - will now be held on Wednesday March 23 in central London. The awards dinner hosted by the Asian Media Group - owners of Pharmacy Business - was initially scheduled to be held on February 3. "Given the uncertainties around Omicron and the impact it could have on our community, we have taken the difficult decision to postpone the twenty-first edition of the Pharmacy Business Awards," an AMG spokesperson said, adding: "We feel this is the best and safest decision for our award winners, guests and partners."

A fourth dose of Covid-19 vaccine is not needed at present, as latest data shows first booster provides high levels of protection against Omicron variant among older adults, says the Joint Committee on Vaccination and Immunisation (JCVI). After analysing latest data from the UK Health Security Agency (UKHSA), JCVI said: "There is no immediate need to introduce a second booster dose, or fourth jab, to the most vulnerable". Data from UKSHA revealed that single booster dose provides around 90 per cent protection against hospitalisation to those aged 65 and over, even after three months of jab. However, protection against mild symptomatic infection is short-lived and drops to around 30 per cent by about three months. The study, which looked at booster doses in those aged over 65, showed that with two vaccine doses, protection against the infection drops to around 70 per cent after three months and to 50 per cent after six months.

England is set to reopen temporary field hospitals to contain a possible overspill of inpatients due to a surge in coronavirus cases, the national health service said Thursday. Fuelled by the highly contagious Omicron variant, daily cases have ballooned, standing at more than 183,000 on Wednesday. NHS England said it would start building the structures in the grounds of eight hospitals in cities including London, Bristol and Leeds from this week, with each designed to house around 100 extra patients. "Given the high level of Covid-19 infections and increasing hospital admissions, the NHS is now on a war footing," National medical director Stephen Powis said. The extra beds are designed for patients who are recovering from illnesses, including those who no longer have Covid, to free up space and staff to treat large numbers of virus cases.

Prime minister Boris Johnson announced on Wednesday (January 19) that restrictions re-imposed in England last month would be lifted by from next Thursday (January 27). In the latest development, the government has decided to end the guidance on working from home, asking employers to make adequate arrangements to return safely to work. From the start of next Thursday, mandatory certification based on vaccines and tests will end, however, organisations can still choose to use the NHS Covid Pass voluntarily. Besides, the legal mandate to wear face masks will go away from next week. Making a statement to the House of Commons on Covid-19, he said that infection levels are falling in England mainly because of the country's "extraordinary booster campaign". He noted more than 36 million Covid-19 booster jabs had been delivered, with over 90 percent of over-60s now given a third dose. "Our scientists believe it is likely that the Omicron wave has now peaked nationally," Johnson added, while cautioning "the pandemic is not over". "I encourage everyone across the country to continue with all the cautious behaviours that we know help to keep each everybody safe."

NHS cancer check has set a new record, despite pressures on hospitals due to Covid-19, the number of people being treated for the cancer remained higher than before the pandemic, revealed NHS. Over the last 12 months almost three million people were referred for cancer checks which is up by over a tenth on the 2.4 million people referred before the pandemic. "Even at the peak of the Omicron wave, referrals for suspected cancer were at 116 per cent of pre-pandemic levels with around 11,000 people getting checked every day over the last year," said NHS. In order to meet increasing demand for cancer checks, NHS services across the country are expanding their diagnostic capabilities through one stop shops for tests, mobile clinics and cancer symptom hotlines, ensuring people are diagnosed and treated as early as possible to give them a much better chance of beating the disease. More than 30,000 people every month are being invited for lung cancer checks through NHS mobile trucks visiting at risk communities across the country, as part of the biggest programme to improve early lung cancer diagnosis in health service history.

Health and social care workers in England, including those working in community pharmacy, will no longer have to have a Covid jab as a condition of employment from later this month, the government said on Tuesday (March 1). The government had announced on January 31 that it intended to revoke the regulations that made vaccination compulsory, subject to the results of a public consultation. The decision was taken because the Omicron strain of the virus was less severe than the Delta variant, and due to high rates of vaccination of people in the UK. Health secretary Sajid Javid told parliament in a written statement that more than 90,000 health and social care workers and members of the public responded to the consultation.

Prime minister Boris Johnson received his Covid-19 booster shot on Thursday (December 2) and urged others to follow suit to help the country fend off the Omicron variant of coronavirus. Wearing a mask, Johnson briefly chatted to staff and others queuing for their shots at the vaccination centre in central London, asking them if they were there to receive a booster dose and thanking them for attending. Johnson, who said it could "have gone either way" when he was treated in hospital for Covid last year, was later filmed rolling up his shirt sleeve and receiving his shot. "Fantastic. Thank you so much," he said to the nurse, before receiving a badge that said "I've boosted my immunity".

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.
