In a recent study published in The Lancet Respiratory Medicine, researchers examine whether coronavirus disease 2019 (COVID-19) vaccines could prevent long COVID symptoms and compare the effectiveness of the Oxford AstraZeneca ChAdOx1 and Pfizer BioNTech BNT162b2 vaccines, which are the two most used COVID-19 vaccines in Europe.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19, has infected over 800 million individuals worldwide since March 2020.

Since the start of the pandemic, concerted efforts throughout the world led to the rapid development of numerous vaccines and subsequent vaccination of large parts of the global population, particularly the elderly and those at high risk of severe COVID-19 due to the presence of comorbidities. These global vaccination efforts successfully reduced the transmission and severity of SARS-CoV-2 infections, thereby significantly lowering mortality rates.

In addition to the Oxford-AstraZeneca ChAdOx1 and Pfizer-BioNTech BNT162b2 vaccines, Ad26.COV2.S and mRNA-1273 developed by Janssen and Moderna, respectively, were the four most commonly used COVID-19 vaccines in Europe. However, the persistence of COVID-19 symptoms and long-term complications affecting multiple organ systems, now cumulatively referred to as long COVID, remains a significant health burden.

To date, the impact of COVID-19 vaccines in preventing the development of long COVID is unclear. About the study

In the present study, researchers used electronic health records and primary care data from the United Kingdom, Spain, and Estonia to evaluate whether COVID-19 vaccination prevented long COVID symptoms.

Data registries comprised information on the demographic characteristics of patients, as well as their medical histories, comorbidities, lifestyle factors, diagnoses, prescriptions, insurance claims for procedures, laboratory tests, clinical measurements, and secondary care referrals. Regional and national registries linked to these databases were used to obtain information on vaccination status and the type of vaccine administered.

Study participants were divided into four cohorts based on the enrollment period, which also corresponded to the priority groups, with cohort one primarily consisting of individuals above the age of 75 years with no history of COVID-19. Individuals above the age of 65, those who were considered clinically vulnerable, and those above the age of 18 with underlying health conditions that increased the risk of COVID-19 were included in cohort two. Cohort three comprised individuals above the age of 50, whereas the fourth cohort included individuals 18 years of age or older.

Long COVID was defined as the presence and persistence of any one of the 25 symptoms, such as fatigue, dyspnea, or cognitive dysfunction 90-365 days after a clinical COVID-19 diagnosis and with no indication of those symptoms during the six months before infection. Alternate definitions of long COVID, with varying time intervals for the presence of persistent symptoms, were used for sensitivity analyses. Study findings

The current study included over 20 million vaccinated and unvaccinated individuals across three European countries and showed that vaccination against SARS-CoV-2 had a 29-52% effectiveness in reducing the risk of long COVID risk. These findings were consistent across numerous sensitivity analyses and varying definitions of long COVID based on clinical diagnoses and differing symptom durations.

The comparative analyses between the effectiveness of BNT162b2 and ChAdOx1 indicated that BNT162b2 was associated with slightly greater long COVID preventative effects than the adenoviral vector vaccine ChAdOx1. Other studies have reported similar results while comparing the efficacies of BNT162b2 and ChAdOx1 in preventing SARS-CoV-2 infection.

The younger population was believed to be at a lower risk of severe SARS-CoV-2 infection than adults above the age of 65 years, which led to lower vaccination uptake rates among younger age groups. However, these individuals are equally vulnerable to long COVID; thus, there remains an urgent need for vaccination across all age groups to reduce the risk of developing long COVID. Conclusions

COVID-19 vaccination reduces the risk of severe SARS-CoV-2 infection and effectively decreases the risk of developing long COVID. Furthermore, as compared to the adenoviral vector vaccine ChAdOx1, the mRNA vaccine BNT162b2 was more effective in preventing COVID-19 severity and long COVID symptoms.

Are tariffs the answer to save America’s declining aluminium industry?

Are tariffs the answer to save America's declining aluminium industry?

On the banks of the Ohio River in a rural corner of one of America’s poorest states sit two factories, one next to the other. 

One is open. The other is shuttered. Both cut to the heart of what Donald Trump hopes he can do to transform America’s industrial base.

Ravenswood, West Virginia, is a town built on aluminium. Since the 1950s, the wonder-metal has kept this place on the map.

Once upon a time, the metal itself was produced here. A massive smelting plant dominated the skyline, and inside, huge furnaces, transforming American aluminium ore (alumina) into the metal we recognise.

The newly smelted metal was then sent by river, rail and road to other factories dotted across the country to be cast – turned to sheet and coil for the nation’s cars, planes, trucks and so much more.

Kaiser Aluminium closed its smelters in 2009. The plant now sits idle. Fencing surrounds it; grass partially obscures the entrance, where hundreds of workers would once have passed.

Two hundred metres down the road, there is a different story.

More on Donald Trump

Constellium Ravenswood is one of the world’s largest factories of its kind.

With over a thousand employees it produces plate, sheet and coiled aluminium for numerous industries: aerospace, defence, transportation, marine and more.

Its products are custom designed for clients including Boeing, Lockheed Martin and NASA.

Constellium Ravenswood is one of the world's largest factories of its kind

But here’s the problem. The Constellium plant uses aluminium now sourced from abroad. America’s primary aluminium production has dropped off a cliff over the past few decades.

The Kaiser plant next door which could have provided the metal for its neighbour to process and press was instead the victim of cheap foreign competition and high energy costs.

Smelting aluminium requires huge amounts of constant energy. If the smelters are ever turned off, the metal inside will solidify, destroying the facility.

In 2023, the annual rate of US primary aluminium production fell 21.4% on the previous year, according to the Aluminium Association.

However, the Canadian Aluminium Association projected that their annual production would be up by 6.12% in 2024 compared to the previous year.

The story is clear – this industry, like so many in America, is in steep decline. Competition and high production and energy costs are having a huge impact.

The danger ahead is that secondary aluminium production in America could go the way of primary production: firms down the supply chain could choose to buy their sheeting and coils from abroad too.

The answer, says President Trump, is tariffs. And the chief executive of Constellium agrees with him.

“We believe in free AND fair trade,” Jean-Marc Germain told Sky News from the company’s corporate headquarters in Baltimore. “And the point is that trade has been free but not fair.”

“There has been massive growth in the capacity installed in China. Kudos to the Chinese people, that is admirable, but a lot of that has been allowed by illegal subsidies. What it means is that overall, trade of aluminium products is broken as an international system. And I think those tariffs are a way to address some of that very uneven playing field that we are seeing today.”

Mr Germain says the tariff plan will reset the market. He accepts that blanket tariffs are a blunt and risky tool, but cuts out circumvention by one country to another.

“Obviously, this process creates some collateral damage. It is clear that not all countries and not all products are unfairly traded. But because of the sheer size of China and the history of Chinese production making its way through certain countries into the US… a blunt approach is required,” he says.

The White House 25% tariff plan for steel and aluminium is global and causing huge angst.

Experts say a long-term domestic rebalance, revitalising the American industrial sector, will take many years and is not guaranteed.

But upending the status quo and disrupting established supply chains risks significant short and medium-term disruption, both at source and destination.

The foreign aluminium arriving at Ravenswood’s Constellium plant to be pressed will now cost 25% more – a hike in price which Mr Germain says his firm can ride out to achieve the longer-term rebalance.

“I’m not going to say that an increase in cost is a good thing for customers. But I think it’s important to look at things and put them in proportion…” he says.

Proportion is not a luxury all can afford. 250 miles to the east, in Washington DC and just four miles from the frenetic policy decisions at the White House, the Right Proper Brewing Company is a dream realised for Thor Cheston.

Thor shows me around his small warehouse-based business that is clearly thriving.

He takes me to the grain silos around the back. The grain is from Canada.

Thor relies on an international supply chain – the cans are aluminium and from Canada too. Some of the malt is from Germany and from Britain.

It is a complex global web of manufacturing to make American beer. Margins are tight.

“We don’t have the luxury of just raising our prices. We’re in a competitive landscape,” Thor says. Competition with big breweries, who can more easily absorb increased costs.

The cans will probably go up in price on his next order. He doesn’t yet know how much of the 25% will be passed on to him by his supplier.

“We’ve dealt with major problems like this before. We’ve had to pivot a lot. We have survived the global pandemic. We’ve done it before, but we don’t want to. We just need a break.”

What about the government’s argument to ‘buy American’?

“It’s not as simple as that,” Thor says.

Will there be impacts from Trump’s latest tariffs?

Back in West Virginia the mighty Ohio River snakes past the Ravenswood factories.

It still carries what’s left of America’s heavy industry. A vast multi-vessel barge full of coal passed as I chatted to locals in the nearby town of Parkersburg, a pleasant place but not the thriving industrial community it once was.

“We used to have a really nice aluminium plant right down the river here and it shut down,” one resident reflects in a passing conversation.

Here you can see why many rolled the dice for Trump.

Sam Cumpstone blames Obama

“In West Virginia, we’re big on coal,” Sam Cumpstone tells me.

He works in the railways to transport coal. The industry went through economic devastation in the late noughties, the closure of hundreds of mines causing huge unemployment.

Sam is clear on who he blames: “Obama shut down mines and made ghost towns in West Virginia. It ruined a lot of people’s lives.”

There is recognition here that Trump’s sweeping economic plans could cause prices to rise, at least in the short term. But for Trump voter Kathy Marcum, the pain would be worth it.

“He’s putting tariffs on other countries that bring their things in, and that way it equals out. It has to be even-stevens as far as I’m concerned… He is a smart businessman. He knows what the hell he’s talking about.

“It might be rough for a little while, but in the long run I think it will be best for the country.”

Communities have been let down over generations – either by politicians or by inevitable globalisation. There is still deep scepticism here.

“No politician worth millions or billions of dollars cares about me or you. Nobody,” Sam tells me at the end of our conversation.

The Trump tariff blueprint is full of jeopardy. If it fails, it will be places like West Virginia, that will be hit hardest again.

Devers fans twice more, now at 12 K's this year

ARLINGTON, Texas — Boston Red Sox designated hitter Rafael Devers became the first major leaguer to strike out 12 times in a season’s first four games.

Devers went 0-for-4 with two more strikeouts Sunday in Boston’s 3-2 loss to the Texas Rangers.

Devers’ latest mark for futility came a day after he became the first big leaguer to be fanned 10 times in the first three games of a season.

He’s 0-for-16, though he did draw a two-out walk in the ninth Sunday to keep the inning alive and put the potential tying run in scoring position.

The 12 strikeouts broke the previous record of 11 in the first four games, which had been done four times previously since 1901, according to SportRadar.

Brent Rooker of the Athletics struck out 11 times to open last season. The others were Atlanta’s Ronald Acuña Jr. in 2020, Minnesota’s Byron Buxton in 2017 and Houston’s Brett Wallace in 2013.

Devers is now solely the Red Sox DH after their offseason acquisition of third baseman Alex Bregman.

Hamlin gets 1st win at Martinsville in 10 years

MARTINSVILLE, Va. — Denny Hamlin ended an agonizing 10-year winless streak at Martinsville Speedway, holding off teammate Christopher Bell in his home state.

The Joe Gibbs Racing star, who was raised a few hours away in the Richmond suburb of Chesterfield, leads active Cup drivers with six victories at Martinsville. But Sunday was Hamlin’s first checkered flag on the 0.526-mile oval in southwest Virginia since March 29, 2015 and also his first with crew chief Chris Gayle, who joined the No. 11 team this season.

With the 55th victory of his career (tying NASCAR Hall of Famer Rusty Wallace for 11th on the all-time list), Hamlin also snapped a 31-race winless streak since last April at Dover. He led a race-high 274 of the final 275 laps after taking the lead from Chase Elliott.

“Chris Gayle, all the engineers, the pit crew, everybody really just deciding they were going to come here with a different approach than what we’ve been over the last few years,” said Hamlin, who was a frequent contender during his 19-race win drought at Martinsville with 10 top fives. “It was just amazing. The car was great. It did everything I needed it do to. Just so happy to win with Chris, get 55. Gosh, I love winning here.”

Bell, who leads the Cup Series with three wins in 2025, finished second after starting from the pole position, and Bubba Wallace took third as Toyotas swept the top three. The Chevrolets of Elliott and Kyle Larson rounded out the top five.

“It was a great weekend for Joe Gibbs Racing,” said Bell, who had finished outside the top 10 the past two weeks. “Showed a lot of pace. All four of the cars were really good. Really happy to get back up front. The last two weeks have been rough for this 20 team. Really happy for Denny. He’s the Martinsville master. Second is not that bad.”

Hamlin had to survive four restarts — and a few strong challenges from Bell — in the final 125 laps as Martinsville produced the typical short-track skirmishes between several drivers.

The most notable multicar accident involved Toyota drivers Ty Gibbs and Tyler Reddick, who had a civil postrace discussion in the pits.

Bubba’s big day Bubba Wallace tied a season best and improved to eighth in the Cup points standings but was left lamenting his lack of speed on restarts after being unable to pressure Hamlin.

“I’m trying to scratch my head on what I could have done different,” said Wallace, who drives the No. 23 Toyota for the 23XI Racing team co-owned by Hamlin and NBA legend Michael Jordan. “My restarts were terrible. One of my best traits, so I need to go back and study that. The final restart, I let that second get away. I don’t know if I had anything for Denny. It would have been fun to try. But all in all, a hell of a day for Toyota.”

Special day turns sour

After being honored Sunday morning with a Virginia General Assembly proclamation commending Wood Brothers Racing’s 75th anniversary, Josh Berry led 40 laps in the team’s hometown race before disaster struck. Berry’s No. 21 Ford was hit in the left rear by the No. 23 Toyota of Wallace while exiting the pits, causing Berry’s car to stall in Turn 2.

Berry, who can withstand a poor finish because his Las Vegas victory qualified him for the playoffs, returned after losing two laps for repairs. He still managed to lead the most laps for Wood Brothers Racing at Martinsville since NASCAR Hall of Famer David Pearson led 180 on April 29, 1973 (the team’s most recent victory at the track just east of its museum in Stuart, Virginia).

Up next

The Cup Series will race next Sunday at historic Darlington Raceway, the South Carolina track that will celebrate a “throwback weekend” that encourages teams to feature vintage paint schemes and crew uniforms.

It’s the first of two annual races on the 1.366-mile oval that dates to 1950. Brad Keselowski won last year’s throwback race, and Chase Briscoe won the Southern 500 last September.
