Covid shots should target newer strains of JN.1 variant in 2025-26 campaign, US FDA advisers say , World News
US Food and Drug Administration (FDA) advisers unanimously recommended on Thursday (May 22) that Covid-19 vaccines for the 2025 to 2026 period should target newer strains of the JN.1 variant.
According to the Centres for Disease Control and Prevention, the LP.8.1 strain — a subvariant of the previously recommended JN.1 strain — accounted for 70 per cent of total cases in the United States over a two-week period ended May 10.
While the LP.8.1 is the predominant circulating strain, other virus subvariants, including LF.7 and XFG, have also been increasingly detected in recent weeks, FDA documents showed earlier this week.
The FDA panel's recommendation aligns with the European Medicines Agency's panel, which recently advised updating Covid vaccines to target the LP.8.1 strain.
Meanwhile, a team of experts from the World Health Organisation has also declared vaccines targeting the LP.8.1 strain as a "suitable alternative" to the current ones.

Philippines warns of health emergency as HIV cases soar
The Philippine Health Ministry has not explained the causes behind a surge in HIV cases among youths. PHOTO: LIANHE ZAOBAO FILE MANILA – The Philippine medical authorities on June 3 warned of a looming 'public health emergency' as HIV infections have soared in 2025, with young males especially hard-hit. On the average, 57 new cases a day were tallied in the country of 117 million people over the first three months of 2025, a 50 per cent jump from a year earlier, Health Ministry data shows. 'We now have the highest number of new cases here in the Western Pacific,' Health Minister Ted Herbosa said in a video message. 'What is frightening is, our youth make up many of the new cases,' he said. 'It would be in our interest to (declare) a public health emergency, a national emergency for HIV to mobilise the entire society, the whole of government to help us in this campaign to reduce the number of new HIV cases,' Dr Herbosa added. The Health Ministry said 95 per cent of newly reported cases were male, with 33 per cent aged 15-24 and 47 per cent aged 25-34. The government did not explain the causes behind the surge, which it said has set back government attempts to hit global targets set by a United Nations campaign to end the Aids epidemic by 2030. Under Philippine law, the president can declare a health emergency if an epidemic poses a threat to national security. The start of the Covid-19 pandemic in 2020 was the last time that was done. Just 55 per cent of those living with HIV in the Philippines have been diagnosed, the Health Ministry said, while only 66 per cent of those diagnosed are on life-saving antiretroviral therapy. Sexual contact remains the predominant mode of transmission, with the bulk of cases since 2007 attributed to men having sex with men. HIV cases have been on the rise in the Philippines since 2021, with 252,800 people estimated to be living with HIV in the country by the end of this year.

Working until 70 isn't so bad provided you feel 55
DENMARK'S recent move to increase the statutory retirement age to 70 for those born after 1970 – the highest in Europe – highlights an obvious and potentially troubling reality: Most of us are facing longer working lives, but that also means we need to remain healthier for longer. While linking the pensionable threshold to improving longevity is fair, up to a point, doing so risks exacerbating health inequalities because the poor become sick and die sooner than the rich. So the focus must be on extending healthy life expectancy for everyone. Closing the gap between lifespans and so-called healthspans can help build public support for later retirement, because fewer years are spent with serious illness or disability, leaving more quality time with grandchildren, on the golf course or at the bingo hall. It can also benefit government finances, by reducing pension expenses and costs associated with chronic disease and elderly care, while ensuring workers are able to keep working. When Otto von Bismarck's Germany became the first nation to offer old-age social security in 1889, the official retirement age was also 70; but at the time, his compatriots were fortunate if they lived past 45. Today, life expectancy for German men and women is around 78 and 83, respectively, meaning men receive a state pension for around 19 years, while for women it is about 22 years, or around 60 per cent longer than in 1980. The rate at which life expectancy improves has slowed in recent years, and not just because of the Covid-19 pandemic; 65-year-olds now gain nearer one additional year with each passing decade compared with around 1.5 years previously, according to the Organisation for Economic Co-operation and Development (OECD). A NEWSLETTER FOR YOU Friday, 2 pm Lifestyle Our picks of the latest dining, travel and leisure options to treat yourself. Sign Up Sign Up Nevertheless, most of us will live longer than our parents and grandparents. (The UK government's online calculator suggests your 42-year-old columnist will expire at 84, with a one-in-four chance I will reach 93. Fingers crossed.) While this is obviously good news, it will put even more pressure on pay-as-you-go social security systems, which face a growing imbalance between the number of retirees and employees. Germany's statutory retirement age is set to increase to 67 by 2031, but its new government has postponed a politically awkward decision on what happens after that. It should consider indexing the retirement age to longer lifespans, as Denmark does, to help avoid a political row about working longer. (Reforms to lift France's retirement age to 64 from 62 led to widespread protests in 2023.) Denmark introduced a quasi-automatic adjustment mechanism in 2006, and variants of this indexation system have been adopted by several European countries. For Danes, an extra year of life expectancy translates to a full year of additional working time, based on a principle that on average, workers should spend 14.5 years in retirement. This feels harsh when Portugal, Finland and elsewhere apply a two-thirds ratio, meaning employees leave the workforce eight months later for every year of extra life expectancy, thereby preventing a compression of the proportion of life spent in retirement. In theory, most of us should be able to work longer because in general, we are healthier than previous generations were at the same stage in life. Citing survey data from 41 advanced and emerging economies, the International Monetary Fund (IMF) argued in a report in April that, on average, the cognitive abilities of a 70-year old in 2022 are comparable to those of a 53-year old in 2000, while in terms of physical frailty, a 70-year old in 2022 is comparable to a 56-year old two decades ago. So there really is no justification for ageism in the workplace. But it is not all good news. There is evidence, for example, that recent cohorts have a higher prevalence of chronic diseases such as diabetes, and while we are living much longer, many of those years are spent in ill health. A study published in December in Jama Network Open found that during the past two decades, the gap between healthspans and total lifespan has widened to 9.6 years, compared with 8.5 years across 183 World Health Organization member countries. The US and UK had two of the largest gaps at 12.4 years and 11.3 years, respectively. Moreover, the affluent and more educated are ageing better those from more disadvantaged backgrounds. In 2022, the Health Foundation think tank found that 60-year-old women in England from the most deprived decile have roughly the same level of diagnosed morbidity as 76-year-old women from the wealthiest decile; meanwhile, men from the most deprived areas die around a decade earlier than the most affluent. Deteriorating health is a big reason why people exit the workforce early, potentially exposing them to poverty, and raising the statutory retirement age can be regressive because wealthier people end up drawing a pension for longer than the poor. Furthermore, telling a construction worker to stay on the scaffolding until 70 clearly is not the same as telling an office worker to keep driving a desk. Setting a pension age that accommodates this heterogeneity is not straightforward, though a combination of disability benefits and retraining can help. But why not index the retirement age to healthspan rather than lifespan, as the longevity author Andrew J Scott has suggested? 'If we set up a national target for healthy life expectancy, we would see much more focus on reducing inequality,' Scott, who is director of economics at the Ellison Institute of Technology in Oxford, told me via e-mail. 'We have a health system overly focused on disease, which is not the same as keeping people healthy.' Regrettably, just 1 to 6 per cent of OECD country health expenditures currently goes towards health promotion and prevention, according to the IMF. Public health campaigns to improve diets should be a priority – US Health and Human Services Secretary Robert F Kennedy Jr's focus on ultra-processed food is encouraging. And as an advocate for strength training – which slows muscle wastage and improves bone health in the elderly – I think governments should fund public gyms or subsidise access, as Singapore does. It should not be just a privileged few that live longer, healthier lives. While working longer looks unavoidable for many, how fast we age and how long we spend in ill health are adaptable, too. Longer lifespans are great, longer healthspans even better. BLOOMBERG

Online claims about Covid-19 autopsy and vaccination laws are false: MOH, Singapore News
The Ministry of Health (MOH) has clarified false claims circulating on social media platforms regarding alleged Covid-19 autopsy findings and vaccination laws in Singapore. In a press release on Tuesday (June 3), MOH said that misinformation from 2021 — involving false claims that Singapore is the first country in the world to perform an autopsy on a Covid-19 body — has resurfaced. The message, initially spread through Whatsapp, also claimed that autopsy results revealed that Covid-19 does not exist as a virus but as a bacterium. MOH said that those claims are false, as previously clarified in 2021. "Singapore has not performed such an autopsy, and it is also not true that Covid-19 is caused by a bacterium," the release said. MOH also addressed new social media posts claiming that Singapore has enacted laws to mandate vaccines and jail unvaccinated individuals following Microsoft co-founder and philanthropist Bill Gates' recent visit to Singapore in May. "Singapore has not passed any laws on vaccinations after Mr Gates' recent visit to Singapore," MOH said, refuting the false claims. MOH reminded members of the public not to spread misinformation, and to visit for the latest information. [[nid:718575]]
