Stroke risk could be cut by common vaccine already offered by NHS
The shingles vaccine could protect against a lot more than we thought
The shingles vaccine could protect against a range of serious health issues including strokes, heart attacks, heart failure and atrial fibrillation, according to an astonishing new study. Analysing over a million South Korean adults aged 50 and older, researchers made remarkable discoveries that could revolutionise preventative healthcare practices for these conditions.
Brain injury specialist Natalie Mackenzie explained the significance to Reach: "These findings are exciting. They indicate that the shingles vaccine doesn't just prevent a painful rash; it can also lower the risk of strokes and heart attacks.
"This study shows how powerful interventions can be - not only does it stop shingles but also protects your heart and brain. For those who qualify, it's well worth doing your research on these findings to fully understand how it may benefit you.
"This is a major health win for anyone eligible for the jab and has an increased risk. As a brain expert, the efficacy noted in this research is certainly meaningful and could be a great tool for reducing the risk of stroke."
Mackenzie pointed out that this investigation adds to existing evidence that preventive measures against certain illnesses can yield "unexpected benefits for your overall health". She also said the results also offer "the potential for clinical consideration".
This means that people at a higher risk of strokes, such as those with high blood pressure or diabetes, could potentially be considered for the jab. As a preventative measure against strokes rather than just shingles.
Currently, the vaccine is available on the NHS for adults turning 65, those in their 70s and people aged 50 with weakened immune systems.
The study, published in the European Heart Journal, discovered that individuals vaccinated against shingles were 23% less likely to experience cardiovascular issues, such as strokes or heart attacks, compared to those who didn't receive the jab.
Specifically, it reduced the risk of:
Stroke by 26%
Heart attacks by 35%
Heart failure by 26%
Heart rhythm disorders like atrial fibrillation by 29%
Overall, men and people under the age of 60 experienced the most significant reductions in risk. The protective effects could last up to eight years, although the risk of these conditions decreased the most two to three years after receiving the jab.
However, the study did have some limitations, namely that the results could vary among different ethnic groups and between the two types of shingles vaccines currently in use. Nonetheless, it does align with previous studies that indicated individuals who contracted shingles faced higher risks of stroke, cardiac events and heart disease.

NHS waiting list for planned treatment falls to lowest level in two years
The NHS waiting list for planned hospital treatment has fallen to its lowest level for two years, figures show. An estimated 7.39 million treatments were waiting to be carried out at the end of April, relating to 6.23 million patients – down from 7.42 million treatments and 6.25 million patients at the end of March. These are the lowest figures since March 2023 for treatments and April 2023 for patients. The news comes after Chancellor Rachel Reeves gave the NHS a cash injection worth an extra £29 billion per year. Health and Social Care Secretary Wes Streeting said: 'We are putting the NHS on the road to recovery after years of soaring waiting times, by providing record investment and fundamental NHS reform. 'Thanks to our interventions and the hard work of NHS staff, the overall waiting list has now fallen in April for the first time in 17 years – dropping by almost a quarter of a million since we took office. 'This is just the start. We've delivered millions of extra appointments since July, we are pushing on with our mission to get the NHS working for patients once again as we deliver our Plan for Change.' Within the new NHS figures, the number of longer waits has grown. Some 1,361 patients in England had been waiting more than 18 months to start routine treatment at the end of April, up from 1,164 in March. There were 9,258 patients who had been waiting more than 65 weeks to start treatment, up from 7,381 the previous month. Overall, 190,068 people in England had been waiting more than 52 weeks to start routine hospital treatment, up from 180,242 at the end of March. The figure had previously fallen for 10 months in a row. NHS England said that, overall, the average time patients had been waiting for planned treatment fell to the lowest level since July 2022 – 13.3 weeks – despite services facing greater demand. Meghana Pandit, NHS England's co-national medical director, said NHS staff were working to 'turn the tide for patients waiting for care'. She said while huge pressure on services remains, 'we are starting to see a real difference across our services – this is just the start of the work we're doing to reform care and deliver improvements for patient'. The data also showed fewer people are getting a diagnosis of cancer or having it ruled out within four weeks. A total of 76.7% of patients urgently referred for suspected cancer were diagnosed or had cancer ruled out within 28 days in April, down from 78.9% in March and 80.2% in February. The Government and NHS England had set a target of March 2026 for this figure to reach 80%. The proportion of patients who had waited no longer than 62 days in April from an urgent suspected cancer referral, or consultant upgrade, to their first definitive treatment for cancer was 69.9%, down from 71.4% in March. GPs in England made 264,880 urgent cancer referrals in April, down from 272,165 in March but up year-on-year from 260,516 in April 2024. Rory Deighton, acute director at the NHS Confederation, said: 'This new data shows that the hard work of NHS leaders and their teams is paying off, with waiting lists falling to their lowest level in two years and A&E performance increasing despite incredibly high demand. 'But our members know there is still a long way to go to further drive down waiting lists and hit the 18-week target.' He said the money pledged by the Chancellor was welcome 'but there are fears that this uplift will not be enough to achieve all the Government's manifesto pledges, including hitting the stretching 92% elective waiting time target by March 2029. 'Many of our members have warned they will not hit the interim target, with only one in two confident they will achieve the 65% elective care interim target by March 2026. 'The solution lies in the radical redesign of pathways, in particular outpatient services, which many of our members are already working towards. 'We look forward to working with them to spread best practice across the country.'

Council tax bills set to rise at fastest rate for two decades, economist warns
Paul Johnson said that local government in England did 'perhaps a little bit better than it might have expected' out of the Chancellor's statement on Wednesday, but the 'sting in the tail' is the assumption that 'council tax bills will rise by 5% a year' as part of the funding. The core spending power of councils is set to increase by 2.6% a year from next year, and 'if English councils do choose 5% increases – and most almost certainly will – council tax bills look set to rise at their fastest rate over any parliament since 2001-05', Mr Johnson said on Thursday. On Wednesday, Ms Reeves said that ministers will not be 'going above' the 5% annual increases in council tax. (PA Graphics) She told ITV: 'The previous government increased council tax by 5% a year, and we have stuck to that. We won't be going above that. 'That is the council tax policy that we inherited from the previous government, and that we will be continuing.' The biggest winner from Wednesday's statement was the NHS, which will see its budget rise by £29 billion per year in real terms. Ruth Curtice, the chief executive of the Resolution Foundation, has said that Britain is turning into a 'National Health State'. Overnight, the think tank said Ms Reeves' announcements had followed a recent trend that saw increases for the NHS come at the expense of other public services. Ms Curtice said: 'Health accounted for 90% of the extra public service spending, continuing a trend that is seeing the British state morph into a National Health State, with half of public service spending set to be on health by the end of the decade.' Defence was another of Wednesday's winners, Ms Curtice said, receiving a significant increase in capital spending while other departments saw an overall £3.6 billion real-terms cut in investment. The Institute for Fiscal Studies (IFS) made similar arguments about 'substantial' investment in the NHS and defence coming at the expense of other departments, although Mr Johnson warned on Wednesday the money may not be enough. In his snap reaction to the review, Mr Johnson said: 'Aiming to get back to meeting the NHS 18-week target for hospital waiting times within this Parliament is enormously ambitious – an NHS funding settlement below the long-run average might not measure up. 'And on defence, it's entirely possible that an increase in the Nato spending target will mean that maintaining defence spending at 2.6% of GDP no longer cuts the mustard.' Ms Curtice added that low and middle-income families had also done well out of the spending review 'after two rounds of painful tax rises and welfare cuts', with the poorest fifth of families benefiting from an average of £1,700 in extra spending on schools, hospitals and the police. She warned that, without economic growth, another round of tax rises was likely to come in the autumn as the Chancellor seeks to balance the books. She said: 'The extra money in this spending review has already been accounted for in the last forecast. 'But a weaker economic outlook and the unfunded changes to winter fuel payments mean the Chancellor will likely need to look again at tax rises in the autumn.' Speaking after delivering her spending review, Ms Reeves insisted she would not have to raise taxes to cover her spending review. She told GB News: 'Every penny of this is funded through the tax increases and the changes to the fiscal rules that we set out last autumn.'
