UKHSA and ONS have published the latest data from the Winter Coronavirus (COVID-19) Infection Study, known as the Winter CIS
Winter COVID-19 Infection Study shows a continued decline in COVID-19 in England and Scotland.
The latest data from the Winter COVID-19 Infection Study, an epidemiological study run in partnership by the UK Health Security Agency (UKHSA) and the Office for National Statistics (ONS), shows a clear decline in the prevalence of SARS-CoV-2 in England and Scotland in the 2 weeks up to 10 January.
Analysis by UKHSA suggests that prevalence in the community is 2.3%, or around one in every 43 people. This represents a decrease in prevalence from 3.1% (one in every 32 people) in the previous report.
Positivity data from the ONS indicates that of the approximately 26,000 participants who reported LFD test results in the last reporting period, 1.9% tested positive for COVID-19, compared to 2.7% in the last report.
The most recent data shows a clear decline in prevalence in Scotland and most of the regions in England. This decline was also observed for the age groups between 18 to 74.
Professor Steven Riley, Director General for Data and Surveillance at UKHSA said: “This week’s data confirms the early signs of a decline in COVID-19 across the country that we saw in last week’s report.
“While this is welcome, it is important to recognise that this does not mean that the risk of becoming ill with COVID-19 has gone away.
“In previous years, we have sometimes seen a decline in early January followed by an increase over the next few weeks, so it remains important that we continue to do what we can to reduce transmission.
“Those people who are most at risk of severe illness from COVID-19 can still receive a seasonal vaccination until the end of this month, and we urge anyone eligible who has not already done so to come forward. You can get a vaccine through your GP, by booking with a local NHS vaccination service, or you can find a COVID-19 vaccination walk-in site.
“If you are showing symptoms of COVID-19 or other respiratory illnesses, you should try to limit your contact with other people as much as possible, especially those who are older or more vulnerable.”
A study to gather vital data on COVID-19 this winter has been launched by the UK Health Security Agency (UKHSA) and the Office for National Statistics (ONS).
The Winter COVID-19 Infection Study (WCIS) will run from November 2023 to March 2024, involving up to 200,000 participants.
UKHSA previously commissioned the Coronavirus Infection Survey (CIS), carried out by the ONS during the pandemic, in partnership with scientific study leads Oxford University.
Recognised globally as the gold standard for surveillance of the virus, CIS gathered and analysed more than 11.5 million swab tests and 3 million blood tests from April 2020 to March 2023.
The new WCIS is a different study and will involve up to 32,000 lateral flow tests being carried out each week, providing key insight into the levels of COVID-19 circulating across the wider community. This sample will be broadly representative of the population according to key characteristics.
While widespread vaccination has allowed us to live with COVID-19, some people remain more vulnerable to severe illness, and this in turn can lead to increased pressures on the NHS over the winter months.
That is why UKHSA is urging eligible adults to book their flu and COVID-19 vaccines online via the NHS website, by downloading the NHS App, or by calling 119 for free, to give themselves the best protection against severe illness and hospitalisation.
UKHSA’s existing surveillance systems already provide up-to-date information on hospital and intensive care unit (ICU) admission rates, but the introduction of this study will allow us to detect changes in the infection hospitalisation rate (IHR), which requires accurate measurement of infection levels in the community.
Calculating the IHR will enable UKHSA to assess the potential for increased demand on health services due to changes in the way the virus is spreading, which could be driven by the arrival of any new variants.
Professor Steven Riley, Director General of Data, Analytics and Surveillance at UKHSA, said: “The data we collected alongside the ONS during the pandemic provided us with a huge amount of valuable insight, so I am delighted that we are able to work together again to keep policymakers and the wider public informed in the coming months.
“UKHSA continues to lead the way internationally on COVID-19 surveillance and by re-introducing a study of positivity in the community, we can better detect changes in the behaviour of the virus.”
The study will use lateral flow devices (LFDs) supplied by UKHSA.
The latest UKHSA technical briefing, published on 22 September, included initial findings of tests performed in the laboratory at Porton Down to examine the effectiveness of LFDs in detecting BA.2.86, and found no reduction in sensitivity compared to previous variants.
The model and scale of this study could also be converted into a programme that captures data on different respiratory viruses, should that be required in future.
Deputy National Statistician Emma Rourke at the ONS said: “ONS is committed to building on the experience of standing up the gold standard CIS. Our resources and statistical expertise are here for the public good, and we are delighted to be delivering this study in partnership with UKHSA.
“There remains a need for robust data to help us continue to understand the virus and its effects during the winter months.
“As well as working to provide UKHSA with regular rates of positivity, we will also be looking at analysis of symptoms, risk factors and the impact of respiratory infections, including long COVID, as part of this important surveillance.”
The latest data from the UK Health Security Agency (UKHSA) shows that scarlet fever cases continue to remain higher than we would typically see at this time of year.There were 851 cases reported in week 46, compared to an average of 186 for the preceding years.
Health officials have recorded more than 430 cases of Strep A in Scotland in two weeks.
Scarlet fever is usually a mild illness, but it is highly infectious. Therefore, look out for symptoms in your child, which include a sore throat, headache, and fever, along with a fine, pinkish or red body rash with a sandpapery feel. On darker skin, the rash can be more difficult to detect visually but will have a sandpapery feel. Contact NHS 111 or your GP if you suspect your child has scarlet fever, because early treatment of scarlet fever with antibiotics is important to reduce the risk of complications such as pneumonia or a bloodstream infection. If your child has scarlet fever, keep them at home until at least 24 hours after the start of antibiotic treatment to avoid spreading the infection to others.
Scarlet fever is caused by bacteria called group A streptococci. These bacteria also cause other respiratory and skin infections such as strep throat and impetigo.
In very rare occasions, the bacteria can get into the bloodstream and cause an illness called invasive Group A strep (iGAS). While still uncommon, there has been an increase in invasive Group A strep cases this year, particularly in children under 10.
There were 2.3 cases per 100,000 children aged 1 to 4 compared to an average of 0.5 in the pre-pandemic seasons (2017 to 2019) and 1.1 cases per 100,000 children aged 5 to 9 compared to the pre-pandemic average of 0.3 (2017 to 2019) at the same time of the year.
So far this season there have been 5 recorded deaths within 7 days of an iGAS diagnosis in children under 10 in England. During the last high season for Group A Strep infection (2017 to 2018) there were 4 deaths in children under 10 in the equivalent period.
Investigations are also underway following reports of an increase in lower respiratory tract Group A strep infections in children over the past few weeks, which have caused severe illness.
Currently, there is no evidence that a new strain is circulating. The increase is most likely related to high amounts of circulating bacteria and social mixing.
There are lots of viruses that cause sore throats, colds and coughs circulating. These should resolve without medical intervention. However, children can on occasion develop a bacterial infection on top of a virus and that can make them more unwell.
As a parent, if you feel that your child seems seriously unwell, you should trust your own judgement. Contact NHS 111 or your GP if:
your child is getting worse
your child is feeding or eating much less than normal
your child has had a dry nappy for 12 hours or more or shows other signs of dehydration
your baby is under 3 months and has a temperature of 38°C, or is older than 3 months and has a temperature of 39°C or higher
your baby feels hotter than usual when you touch their back or chest, or feels sweaty
your child is very tired or irritable
Call 999 or go to A&E if:
your child is having difficulty breathing – you may notice grunting noises or their tummy sucking under their ribs
your child is floppy and will not wake up or stay awake
Good hand and respiratory hygiene are important for stopping the spread of many bugs. By teaching your child how to wash their hands properly with soap for 20 seconds, using a tissue to catch coughs and sneezes, and keeping away from others when feeling unwell, they will be able to reduce the risk of picking up or spreading infections.
Dr Colin Brown, Deputy Director, UKHSA, said: “We are seeing a higher number of cases of Group A strep this year than usual.
“The bacteria usually causes a mild infection producing sore throats or scarlet fever that can be easily treated with antibiotics.
“In very rare circumstances, this bacteria can get into the bloodstream and cause serious illness – called invasive Group A strep (iGAS). This is still uncommon; however, it is important that parents are on the lookout for symptoms and see a doctor as quickly as possible so that their child can be treated and we can stop the infection becoming serious.
“Make sure you talk to a health professional if your child is showing signs of deteriorating after a bout of scarlet fever, a sore throat, or a respiratory infection.”
The UK has become the first country to approve a dual vaccine which tackles both the original Covid virus and the newer Omicron variant.The vaccine will now be part of the autumn booster campaign.
The Joint Committee on Vaccination and Immunisation (JCVI) has published its advice on which vaccines should be used in this year’s autumn booster programme.
All of the available boosters provide good protection against severe illness from COVID-19 and the Committee has emphasised that getting a booster in good time before the winter season is more important for those eligible than the type of vaccine that is received.
The vaccines advised for use in the autumn booster programme are:
For adults aged 18 years and above:
Moderna mRNA (Spikevax) bivalent Omicron BA.1/Original ‘wild-type’ vaccine
Moderna mRNA (Spikevax) Original ‘wild-type’ vaccine
Pfizer-BioNTech mRNA (Comirnaty) Original ‘wild-type’ vaccine
in exceptional circumstances, the Novavax Matrix-M adjuvanted wild-type vaccine (Nuvaxovid) may be used when no alternative clinically suitable UK-approved COVID-19 vaccine is available
For people aged 12 to 17 years:
Pfizer-BioNTech mRNA (Comirnaty) Original ‘wild-type’ vaccine
For people aged 5 to 11 years:
Pfizer-BioNTech mRNA (Comirnaty) Original ‘wild-type’ vaccine paediatric formulation
‘Bivalent’ vaccines have been developed by global manufacturers since the emergence and dominance of the Omicron variant. These vaccines contain two different antigens (substances that induce an immune response) based on two different COVID-19 strains, or variants. The original mRNA vaccines contain one antigen (monovalent), based on the original ‘wild-type’ strain.
Studies indicate the Moderna bivalent vaccine produces a marginally higher immune response against some variants than the Moderna mRNA Original ‘wild-type’ vaccine. The clinical relevance of these small differences is uncertain.
The committee will consider further bivalent vaccines for use in the programme as they are approved by the MHRA.
In its latest advice the JCVI has stated that, where feasible, it would be preferable for a single type of booster vaccine to be offered throughout the duration of the autumn programme for simplicity of deployment.
Professor Wei Shen Lim, Chair of COVID-19 immunisation on the JCVI, said: “All of the available booster vaccines offer very good protection against severe illness from COVID-19. As more vaccines continue to be developed and approved, the JCVI will consider the benefits of including them in the UK programme.
“It is important that everyone who is eligible takes up a booster this autumn, whichever vaccine is on offer. This will increase your protection against being severely ill from COVID-19 as we move into winter.”
Dr Mary Ramsay, Head of Immunisation at UKHSA, said: “Although cases of COVID-19 are relatively low at present, we are expecting to see the virus circulating more widely during the winter months.
“The booster is being offered to those at higher risk of severe illness and by taking up the booster vaccine this autumn, you will increase your protection ahead of the winter months, when respiratory viruses are typically at their peak.”
Up to 25 July 2022, there were 2,367 confirmed and 65 highly probable monkeypox cases in the UK: 2,432 in total.
To expand the UK’s capability to detect monkeypox cases, some NHS laboratories are now testing suspected monkeypox samples with an orthopox polymerase chain reaction (PCR) test (orthopox is the group of viruses which monkeypox is part of).
Since 25 July 2022, the monkeypox case definition recognises those who are orthopox-positive as highly probable cases, and those who test positive on a monkeypox PCR test as confirmed cases.
Dr Sophia Makki, National Incident Director at UKHSA, said: “Monkeypox cases continue to rise, with the virus being passed on predominantly in interconnected sexual networks.
“Before you have sex, go to a party or event, check yourself for monkeypox symptoms, including rashes and blisters.
“If you have monkeypox symptoms, take a break from attending events or sex until you’ve called 111 or a sexual health service and been assessed by a clinician.
“Vaccination will further strengthen our monkeypox response and so we urge all those who are eligible for the vaccine to take it up when offered. It will help protect yourself and others you have had close contact with.
“While the infection is mild for many, it can cause severe symptoms and hospitalisation in some.
“Please remember that the vaccine may not provide complete protection against monkeypox, so it is still important to be alert for the symptoms of monkeypox and call 111 or a sexual health clinic if you develop any.”
The NHS will provide the vaccine to those eligible, so please wait until you are contacted.
While anyone can catch monkeypox, the majority of monkeypox cases in the UK continue to be in gay, bisexual and other men who have sex with men (MSM), with the infection being passed on mainly through close contact between people in interconnected sexual networks.
Before you go to a party or event, check yourself for monkeypox symptoms, including rashes and blisters.
If you have monkeypox symptoms, take a break from attending events or sex until you’ve called 111 or a sexual health service and been assessed by a clinician.
It can take up to 3 weeks for symptoms to appear after being in contact with someone with monkeypox, so stay alert for symptoms after you have skin to skin or sexual contact with someone new
UK Health Security Agency (UKHSA) releases level 3 heat-health alert for parts of UK
Forecasters warn temperatures will continue to climb and soar past 30 degrees C in some parts of the country
TUC calls on employers to make sure staff are protected from the sun and heat
The TUC has urged employers to make sure their staff are protected from the sun and heat after the UK Health Security Agency (UKHSA) issued a heat-health alert yesterday.
A Level 2 heat-health alert has been issued for the South West, East Midlands, West Midlands, North West and Yorkshire and the Humber regions.
And a Level 3 alert has also been issued for the East of England, South East and London regions.
Both alert levels are in place until 9am on Friday (15 July), with warm weather forecast across the country throughout the course of next week.
Climate change means that the UK will be subject to more frequent and intense heat waves – putting workers at greater risk.
Health warning
Working in hot weather can lead to dehydration, muscle cramps, rashes, fainting, and – in the most extreme cases – loss of consciousness. Outdoor workers are three times more likely to develop skin cancer.
The TUC says employers can help their workers by:
Sun protection: Prolonged sun exposure is dangerous for outdoor workers, so employers should provide sunscreen.
Allowing flexible working: Giving staff the chance to come in earlier or stay later will let them avoid the stifling and unpleasant conditions of the rush hour commute. Bosses should also consider enabling staff to work from home while it is hot.
Keeping workplace buildings cool: Workplaces can be kept cooler and more bearable by taking simple steps such as opening windows, using fans, moving staff away from windows or sources of heat.
Climate-proofing workplaces: Preparing our buildings for increasingly hot weather, by installing ventilation, air-cooling and energy efficiency measures.
Temporarily relaxing their workplace dress codes: Encouraging staff to work in more casual clothing than normal – leaving the jackets and ties at home – will help them keep cool.
Keeping staff comfortable: Allowing staff to take frequent breaks and providing a supply of cold drinks will all help keep workers cool.
Talking and listening to staff and their union: Staff will have their own ideas about how best to cope with the excessive heat.
Sensible hours and shaded areas for outdoor workers: Outside tasks should be scheduled for early morning and late afternoon, not between 11am-3pm when UV radiation levels and temperatures are highest. Bosses should provide canopies/shades where possible.
The law
There’s no law on maximum working temperatures. However, during working hours the temperature in all indoor workplaces must be ‘reasonable’.
Employers have a duty to keep the temperature at a comfortable level and provide clean and fresh air.
The TUC would like to see a change in the law so that employers must attempt to reduce temperatures if they get above 24 degrees C and workers feel uncomfortable. And employers should be obliged to provide sun protection and water.
The TUC would also like ministers to introduce a new absolute maximum indoor temperature, set at 30 degrees C (or 27 degrees C for those doing strenuous jobs), to indicate when work should stop.
With climate change bringing higher temperatures to the UK, the government needs a plan on how to adapt and keep workers safe.
TUC General Secretary Frances O’Grady said:“We all love it when the sun comes out. But working in sweltering conditions in a baking shop or stifling office can be unbearable and dangerous.
“Indoor workplaces should be kept cool, with relaxed dress codes and flexible working to make use of the coolest hours of the day.
“And bosses must make sure outdoor workers are protected with regular breaks, lots of fluids, plenty of sunscreen and the right protective clothing.”
Outbreak continues to grow and cases remain primarily in gay, bisexual, or men who have sex with men (GBMSM), within interconnected sexual networks.
The UK Health Security Agency (UKHSA) has published its second technical briefing on the ongoing monkeypox outbreak. The briefing shares UKHSA analyses with public health investigators and academic partners.
The latest epidemiological data, findings from interviews with patients and preliminary analyses are included to understand how the outbreak is evolving and to inform timely and effective public health interventions.
Investigations and modelling continue to show that the outbreak is growing and cases remain primarily in gay, bisexual, or men who have sex with men (GBMSM), within interconnected sexual networks.
UKHSA continues to work with partners including the Terrence Higgins Trust, Stonewall and the GBMSM community to raise awareness of the signs and symptoms of monkeypox. The LGBT Consortium and Pride organisers across the UK have been encouraged to help share public health messaging during Pride month.
79% of England cases are known to be London residents and 99% of all confirmed cases are male, with 5 confirmed female cases. The median age of confirmed cases in the UK was 37 years old.
Of the 813 cases identified in England up to 22 June, 321 (39.5%) had enhanced surveillance questionnaires. The majority (96%) of cases were GBMSM, with further data to indicate transmission is occurring in some sexual networks both internationally and domestically.
Cases frequently reported history of a sexually transmitted infection (STI) in the last year (54.2%) and 10 or more sexual partners in the last 3 months (31.8%). Existing links between cases and sexual health services will be used to identify those at highest risk who are eligible for pre-exposure vaccination.
Dr Meera Chand, Director of Clinical and Emerging Infections, UKHSA said: “If you’ve recently had new or multiple sexual partners, please be vigilant to the symptoms of monkeypox. Currently the majority of cases have been in men who are gay, bisexual or have sex with men. However, anyone who has had close contact with an individual with symptoms is also at increased risk.
“If you are concerned that you may have monkeypox, don’t go to events, meet with friends or have sexual contact. Instead, stay at home and contact 111 or your local sexual health service for advice. Please contact the clinic ahead of your visit and avoid close contact with others until you’ve been reviewed by a clinician.
“To assist with our contact tracing, we encourage everyone to ensure they exchange contact details with sexual partners, to help us limit further transmission where cases occur.
“We are grateful to all those who have come forward for testing and who help us understand the outbreak through participating in studies and investigations.”
UKHSA will continue to publish regular technical briefings as the response to the outbreak continues.
Latest updates on SARS-CoV-2 variants detected in the UK
The UK Health Security Agency (UKHSA) is reminding people to ensure their COVID-19 vaccinations are up to date and to continue following COVID-safe behaviours, as latest technical data indicates BA.4 and BA.5 have become dominant in the UK and are driving the recent increase in infections.
The UKHSA’s COVID-19 variant technical briefing 43, published today, includes epidemiological analysis that shows that Omicron BA.4 and BA.5 now make up more than half of new COVID-19 cases in England, accounting for approximately 22% and 39% of cases, respectively.
Omicron BA.4 and Omicron BA.5 were designated as variants of concern on 18 May on the basis of an apparent growth advantage over the previously-dominant Omicron BA.2 variant.
UKHSA’s latest analysis suggests that Omicron BA.5 is growing 35.1% faster than Omicron BA.2, while Omicron BA.4 is growing approximately 19.1% faster. This suggests that BA.5 is likely to become the dominant COVID-19 variant in the UK.
The increasing prevalence of Omicron BA.4 and BA.5 is likely to be a factor in the recent increase in cases seen in the UK and elsewhere, though there is currently no evidence that Omicron BA.4 and BA.5 cause more severe illness than previous variants.
So far, vaccination means that the rise in cases is not translating to a rise in severe illness and deaths. UKHSA scientists are urging anyone who has not had all the vaccines they are eligible for to make sure that they get them as soon as possible.
COVID-19 HAS NOT GONE AWAY, so it is also vitally important that people continue to follow the guidance. Stay at home if you have any respiratory symptoms or a fever and limit contact with others until you are feeling better, particularly if they are likely to be at greater risk if they contract COVID-19.
Professor Susan Hopkins, Chief Medical Advisor at UKHSA said: “It is clear that the increasing prevalence of Omicron BA.4 and BA.5 are significantly increasing the case numbers we have observed in recent weeks. We have seen a rise in hospital admissions in line with community infections but vaccinations are continuing to keep ICU admissions and deaths at low levels.
“As prevalence increases, it’s more important than ever that we all remain alert, take precautions, and ensure that we’re up to date with COVID-19 vaccinations, which remain our best form of defence against the virus. It’s not too late to catch up if you’ve missed boosters, or even first doses so please take your recommended vaccines.
“Our data also show that 17.5 per cent of people aged 75 years and over have not had a vaccine within the past six months, putting them more at risk of severe disease. We 2urge these people in particular to get up-to-date.
“If you have any symptoms of a respiratory infection, and a high temperature or feel unwell, try to stay at home or away from others – especially those who are elderly or vulnerable. Face coverings in crowded indoor spaces and hand washing will help to reduce transmission of infection and are especially important if you have any respiratory symptoms.”
UKHSA encourage everyone to continue to follow the most up-to date guidance.
As we learn to live safely with COVID-19, there are actions we can all take to help reduce the risk of catching COVID-19 and passing it on to others.
The risk of catching or passing on COVID-19 is greatest when someone who is infected is physically close to, or sharing an enclosed or poorly ventilated space with, other people.
There are simple things you can do in your daily life that will help reduce the spread of COVID-19 and other respiratory infections and protect those at highest risk.
Things you can choose to do are:
Get vaccinated
Let fresh air in if meeting others indoors
Practise good hygiene:
wash your hands
cover your coughs and sneezes
clean your surroundings frequently
Wear a face covering or a face mask, particularly if you are in crowded and enclosed spaces.
Scotland saw the largest increase in Covid cases in the UK last week, according to the Office for National Statistics (ONS).
It estimates about 250,700 people – one in 20 – had the virus in the week ending 17 June – an increase on the previous week when about 176,900, or one in 30 people, had Covid.
Meanwhile, NHS Lothian said a fifth of its nursing staff were off work as a result of the virus. With a 50% rise in hospital inpatients testing positive in the last week, NHS Lothian says its services are coming under increasing pressure.
The UK Health Security Agency (UKHSA) has detected 2 additional cases of monkeypox, one in London and one in the South East of England.
The latest cases bring the total number of monkeypox cases confirmed in England since 6 May to nine, with recent cases predominantly in gay, bisexual or men who have sex with men (MSM).
The 2 latest cases have no travel links to a country where monkeypox is endemic, so it is possible they acquired the infection through community transmission.
The virus spreads through close contact and UKHSA is advising individuals, particularly those who are gay, bisexual or MSM, to be alert to any unusual rashes or lesions on any part of their body, especially their genitalia, and to contact a sexual health service if they have concerns.
Monkeypox has not previously been described as a sexually transmitted infection, though it can be passed on by direct contact during sex. It can also be passed on through other close contact with a person who has monkeypox or contact with clothing or linens used by a person who has monkeypox.
The 2 new cases do not have known connections with previous confirmed cases announced on 16, 14 and 7 May.
UKHSA is working closely with the NHS and other stakeholders to urgently investigate where and how recent confirmed monkeypox cases were acquired, including how they may be linked to each other.
The virus does not usually spread easily between people. The risk to the UK population remains low.
Anyone with concerns that they could be infected with monkeypox is advised to contact NHS 111 or a sexual health clinic. People should notify clinics ahead of their visit. We can assure them their call or discussion will be treated sensitively and confidentially.
Monkeypox is a viral infection usually associated with travel to West Africa. It is usually a mild self-limiting illness, spread by very close contact with someone with monkeypox and most people recover within a few weeks.
Dr Susan Hopkins, Chief Medical Adviser, UKHSA, said: “These latest cases, together with reports of cases in countries across Europe, confirms our initial concerns that there could be spread of monkeypox within our communities.
“UKHSA has quickly identified cases so far and we continue to rapidly investigate the source of these infections and raise awareness among healthcare professionals.
“We are particularly urging men who are gay and bisexual to be aware of any unusual rashes or lesions and to contact a sexual health service without delay if they have concerns. Please contact clinics ahead of your visit.
“We are contacting any identified close contacts of the cases to provide health information and advice.
“Clinicians should be alert to individuals presenting with rashes without a clear alternative diagnosis and should contact specialist services for advice.”
Symptoms
Initial symptoms of monkeypox include fever, headache, muscle aches, backache, swollen lymph nodes, chills and exhaustion. A rash can develop, often beginning on the face, then spreading to other parts of the body including the genitals.
The rash changes and goes through different stages, and can look like chickenpox or syphilis, before finally forming a scab, which later falls off.
Boosters continue to provide high levels of protection against severe disease from Omicron in older adults
Latest data from UKHSA shows booster doses are continuing to provide high levels of protection against severe disease from the Omicron variant among older adults.
Figures show that around 3 months after they received the third jab, protection against hospitalisation among those aged 65 and over remains at about 90%.
With just 2 vaccine doses, protection against severe disease drops to around 70% after 3 months and to 50% after 6 months.
The Joint Committee on Vaccination and Immunisation (JCVI) has taken this latest evidence into account in their ongoing review of the booster programme.
The Committee advises that at this present time:
there is no immediate need to introduce a second booster dose, or fourth jab, to the most vulnerable (care home residents and those aged over 80) – the timing and need for further booster doses will continue to be reviewed as the data evolves
priority should continue to be given to rolling out first booster doses to all age groups
unvaccinated individuals should come forward for their first 2 doses as soon as possible
Professor Wei Shen Lim, the JCVI’s chair of COVID-19 immunisation, said: “The current data shows the booster dose is continuing to provide high levels of protection against severe disease, even for the most vulnerable older age groups.
“For this reason, the committee has concluded there is no immediate need to introduce a second booster dose, though this will continue to be reviewed.
“The data is highly encouraging and emphasises the value of a booster jab. With Omicron continuing to spread widely, I encourage everyone to come forward for their booster dose, or if unvaccinated, for their first 2 doses, to increase their protection against serious illness.”
The latest study looked at booster doses in those aged over 65, who were among the first to be eligible when the booster rollout began in mid-September.
Whilst with a booster dose, the duration of protection against severe disease remains high, protection against mild symptomatic infection is more short-lived and drops to around 30% by about 3 months.
