Britain's Covid booster campaign is set to kick off this September, after the country became the first in the world to approve an Omicron-adapted shot. Around 26 million people in Britain are estimated to be eligible for an autumn Covid-19 booster, having had at least two Covid vaccine doses already, a UK Health Security Agency (UKHSA) spokesperson said. The preference is to deploy what is known as a "bivalent vaccine" that targets both the original virus and the Omicron variant through the autumn campaign, but that will depend on the health regulator (MHRA) approving such shots and the state of vaccine supplies. The UK's Joint Committee on Vaccination and Immunisation (JCVI) has advised boosters should be given to over-50s, individuals in clinical risk groups, frontline workers and care-home staff ahead of the winter, when respiratory viruses are typically at their peak. On Monday (August 15), the MHRA gave Moderna's bivalent shot conditional approval. The endorsement of the vaccine is based on data that showed it produced a marginally better immune response against some Omicron variants, versus the original novel coronavirus - although whether that translates into stronger protection against serious disease is unclear.

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."

Britain on Tuesday (January 4) faced warnings of an impending hospital crisis due to staff shortages caused by a wave of Omicron infections, as the country returned to work after Christmas. However, Britain's vaccine minister said hospitalised Covid-19 patients were showing less severe symptoms than before, adding that there was no need for further restrictions at this stage. Prime minister Boris Johnson resisted imposing stringent lockdown measures in England ahead of New Year as Omicron fuelled a spike in cases to record highs. While hospitalisations are rising they have not tracked the trajectory of daily cases, possibly reflecting the impact of vaccines and booster shots, the likely lower severity of Omicron and the time lag in people going into hospital. "At the moment, if you look at the people who have been hospitalised, they are going in with less severe conditions than before," minister for Vaccines and Public Health Maggie Throup told Sky News, adding that the "Plan B" Johnson brought in in December was working. "The numbers that are in hospital beds is about half what it was a year ago - and that just shows the power of the vaccine."

Britain has become the first country to approve a Codiv-19 vaccine that targets both the original and Omicron variant of the virus. Medicines regulator MHRA approved the so-called bivalent vaccine made by US drug company Moderna as a booster for adults. The agency's decision was based on clinical trial data that showed the booster triggered "a strong immune response" against both Omicron (BA.1) and the original 2020 virus, it said. The MHRA also cited an exploratory analysis in which the shot was also found to generate a good immune response against the currently dominant Omicron offshoots BA.4 and BA.5. "The first generation of Covid-19 vaccines being used in the UK continue to provide important protection against the disease and save lives," MHRA chief executive June Raine said in a statement. "What this bivalent vaccine gives us is a sharpened tool in our armoury to help protect us against this disease as the virus continues to evolve."

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.

French drugmaker Sanofi said on Monday (June 13) an upgraded version of the Covid-19 vaccine candidate it is developing with GSK showed potential in two trials to protect against the virus's main variants of concern, including the Omicron BA.1 and BA.2 strains, when used as a booster shot. While the two companies' first experimental Covid shot is undergoing review by the European Medicines Agency, Sanofi and GSK have continued work on a vaccine that is moulded on the now-supplanted Beta variant, hoping still that it will confer broad protection against future viral mutations. Sanofi said this new vaccine candidate was shown to significantly boost antibody levels against a number of variants of concern, when given to trial participants who had an initial course of mRNA vaccines, a type made by BioNTech-Pfizer and Moderna. In a separate trial conducted by a French hospitals network, Sanofi's Beta-adapted booster shot triggered a higher immune response than Sanofi's first-generation shot or Pfizer-BioNTech's established vaccine in previously vaccinated volunteers.

It is not sustainable to give Covid-19 booster shots every three to six in the long term, Britain's chief scientific adviser said on Tuesday (January 4), even though the booster rollout is needed in the short term to combat the Omicron variant. "It would be a situation that isn't tenable to say everyone's going to need to be having another vaccine every three or six months. "That's not the long-term view of where this goes to," Patrick Vallance said at a news conference, adding that annual booster shots against Covid-19 might be necessary, similar to flu shots.

For the first time, Covid-19 vaccines will be available for purchase from pharmacies in Britain from April 1. As revealed by The Times, Boots is set to launch a private vaccination service next week to ensure that people "remain ready to respond to this constantly evolving and unpredictable virus." Under the NHS national immunization programme (NIP), Covid booster vaccines are only offered to those at high risk, including over-65s or patients with weakened immune systems. From April 1, anyone aged 12 or over can get the Pfizer-BioNTech Covid-19 vaccine at 50 Boots stores for £98.95. While it's highly unlikely for healthier young adults to experience severe Covid-19, getting the single-dose vaccine can protect them from discomforting symptoms like coughs and sore throats. A spokesperson for Boots told the publication that their private service is the extension of their existing delivery of Covid-19 vaccinations for the NHS.

The Pharmacists' Defence Association (PDA) has urged pharmacists working in Covid-19 vaccination role to report any concerns about the needles and syringes supplied with the Moderna Spikevax Bivalent vaccine. The association has heard reports of bending when vaccinators pierce the top of the vial containing the Covid-19 vaccine doses, needles falling out during manipulation and appearing to be bent even before removal from the packaging. PDA has advised its members who are working in a Covid-19 vaccination role "to report any concerns via the Yellow Card medical device reporting system, and to keep up to date with NHS clinical updates for ongoing information and guidance." Current advice from the NHS includes sharing of video and poster resources (available on FutureNHS) which have been produced by the supplier to support the introduction of the new administration needles and syringes for Spikevax Bivalent. This is following a switch from BD Flu+ 23G x 25mm 1ml syringe combined needle and syringe (CNS) to the Owen Mumford Unifine Safety Retractable Needle 25G x 25mm & 1ml Syringe.

The NHS Covid-19 vaccination programme has administered more than 40 million second doses following a bumper week that saw over 200,000 people coming forward for their second jab. Last week, more than 65,000 people aged 18 and over also stepped up to get their first dose of the Covid-19 jab. The NHS continued to encourage people to come forward for their first, second or third doses. Recent data from the UK Health Security Agency (UKHSA) showed that two doses of the vaccine are not enough to avoid the Omicron infection, but a booster significantly increases protection against the variant. Since the start of vaccination programme, NHS England has administered more than 113 million jabs in total. However, more than 1.1 million people aged 18 and over have still not come forward for their second dose.

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."

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.

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.
