The Joint Committee on Vaccination and Immunisation (JCVI) on Thursday (May 19) said that an anticipated autumn Covid booster campaign would be aimed at people aged over 65, care home residents, frontline health and social care workers and all adults in a clinical risk group. The UK is offering a spring booster to the over-75s, care home residents and immunosuppressed people, and ministers have spoken openly of plans for a further booster campaign in the autumn. In interim advice, the JCVI stopped short of recommending another shot for all adults, though said the advice would be reviewed and updated. "The JCVI's current view is that in autumn 2022, a Covid-19 vaccine should be offered to: residents in a care home for older adults and staff; frontline health and social care workers; all those 65 years of age and over; and adults aged 16 to 64 years who are in a clinical risk group," the UK Health Security Agency said in a statement. Prime minister Boris Johnson, who was fiercely criticised for his handling of the early stages of the pandemic, lifted Covid restrictions in England in February, crediting Britain's quick initial vaccine rollout and the rollout of boosters with breaking the link between cases and deaths.

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.

Covid-19 vaccine makers are shifting gears and planning for a smaller, more competitive booster shot market after delivering as many doses as fast as they could over the last 18 months. Executives at the biggest Covid vaccine makers including Pfizer and Moderna said they believe most people who wanted to get vaccinated against Covid have already done so - more than five billion people worldwide. In the coming year, most Covid vaccinations will be booster shots, or first inoculations for children, which are still gaining regulatory approvals around the world, they said. Pfizer, which makes its shot with Germany's BioNTech and Moderna still see a major role for themselves in the vaccine market even as overall demand declines. Upstart US vaccine maker Novavax and Germany's CureVac, which is working with GlaxoSmithKline, are developing vaccines they hope to target at the booster market. The roles of AstraZeneca and Johnson & Johnson, whose shots have been less popular or effective, are expected to decline in this market.

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.

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.

Health authorities in India have said that Biological E's Covid-19 vaccine Corbevax can be administered as a booster dose in people who have taken the country's other two main shots, Covaxin and AstraZeneca's Covishield, from Friday (Aug 12). Corbevax will be available to over 18s as precautionary booster six months after a second dose, the health ministry said in an August 8 letter to state authorities. Covishield is produced for the Indian market by the Serum Institute of India under licence from AstraZeneca, while Bharat Biotech makes Covaxin. India has so far administered more than 2 billion Covid vaccine shots, including 113 million boosters, all of which have so far been of the same vaccine as the recipient's first two doses. The government says about 89 per cent of Indians above the age of 12 have had two doses.

As part of efforts to streamline spending and enhance resource allocation within the healthcare system, the NHS has chosen to cease providing the free vaccinations for all, which were initially introduced in 2020. Approximately 12 million British citizens will not have access to free flu vaccinations and Covid-19 boosters during the upcoming winter, according to NHS. Furthermore, the NHS plans to defer flu vaccine distribution to October, aiming to heighten protection for those aged 65 and older and other eligible groups in the high-risk winter months. However, this has stirred panic among pharmacies, given their advanced planning based on the initial start date of September 1 for vaccinations. On Tuesday (Aug. 8), the Joint Committee on Vaccination and Immunisation (JCVI) released NHS guidelines indicating that Covid-19 booster shots, starting from autumn, will not be provided to individuals aged 50 to 64 who are in otherwise good health. Similar guidance had already been released for flu, rendering 12 million middle-aged Britons ineligible for free jabs, JCVI said. Prior to the pandemic, influenza vaccinations were available to healthy adults aged over 65, alongside children and younger adults with medical conditions. Amidst the pandemic, the distribution of flu vaccinations was expanded to include individuals aged 50 to 64, in alignment with the criteria for Covid-19 boosters.

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."

Prime minister Boris Johnson has said he is cautious about rising cases of Covid in Europe, warning of gathering "storm clouds" of a new wave of coronavirus infections. He made the statement during a visit today (November 12) to a vaccination centre at a community pharmacy in Sidcup, London while encouraging people to come forward for Covid-19 boosters. The UK has had much higher rates of Covid-19 than the rest of Western Europe since the summer when Johnson scrapped coronavirus restrictions in England. However, rates in Britain are now coming down just as they are rising sharply in countries such as Germany, Austria and the Netherlands. Parts of Eastern Europe have also seen a sharp rise in cases.

US biotech firm Moderna will build a new research and manufacturing centre in Britain to develop vaccines against new Covid-19 variants, other respiratory illnesses and help improve readiness for any future pandemics. The facility is expected to start producing shots in 2025 and Britain has made a commitment to buy Moderna's vaccines for the next decade under the agreement. Moderna's Covid-19 vaccines, which use messenger RNA (mRNA) technology, were among those deployed in Britain to tackle the crisis and enable prime minister Boris Johnson to reopen the economy from stringent lockdowns. Moderna chief executive Stephane Bancel said the priority was to develop a shot combining refreshed boosters against Covid, flu and Respiratory Syncytial Virus (RSV). "By building a plant in the UK, we are also providing the UK Government - which has a long term partnership with us, with this agreement - with the ability to be pandemic ready," Bancel said on Wednesday.

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."

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.
