Coronavirus vaccines offer protection not only against infection and serious illness but may also help prevent so-called “Long COVID,” where symptoms can last for several weeks or months, according to new research from scientists at Kings College London.  There are no official figures, but it’s thought millions of people worldwide who contracted the coronavirus have suffered from so-called “Long COVID,” with reported symptoms including muscle pain, fatigue, shortness of breath and brain fog lasting longer than four weeks. Sorry, but your browser cannot support embedded video of this type, you can

I think people are still getting told that it’s due to anxiety. Some doctors don’t fully understand this condition,” Sherwood told VOA. “It is a case of treating symptoms. Research is ongoing as to the mechanisms of Long COVID and it’s not fully understood. There are quite a lot of theories, many of which have been backed up with research. But we haven’t reached the stage where we have targeted treatments,” Sherwood added. The research from Kings College London suggests that coronavirus vaccines halve the risk of suffering from long COVID, for the very low number of people who become infected after vaccination. The scientists based their research on Britain’s “Zoe” COVID study app, which tracked the self-reported symptoms of 1.2 million people between December 2020 and July of this year. Zero-point-two percent of vaccinated respondents reported being infected with the coronavirus. Of those, 5% reported suffering from long COVID, compared to 11% of unvaccinated people. “So, the vaccine will protect you from becoming ill from the virus. It will also protect you if you do get symptoms from becoming long-term ill from this virus,” said Sterghios Moschos, a virologist at the University of Northumbria, who was not involved in the research.  “This means that if you get exposed to the virus and you’ve been vaccinated, the vast chances are that you are not even going to be able to tell if you’ve been infected. That’s how good the vaccines are,” he added. The findings will fuel the debate over whether to offer vaccines to children, as schools start to reopen. Another recent study in Britain found that one in seven children suffers from Long COVID three months after infection, with headaches and fatigue listed as the most common symptoms.  Britain has yet to approve vaccines for healthy children. In the meantime, measures such as improved ventilation, social distancing and face masks should continue, argues Moschos. “We need to continue preventing transmission. We must not rely only on vaccines,” he told VOA.  Several countries, including the United States, have already begun vaccination programs for those 12 and older.

U.K. Prime Minister Boris Johnson plans Tuesday to fulfill a election promise to grapple with the rocketing cost of the long-term care needed by Britain’s growing older population. To do it, he appears set to break another election vow: not to raise taxes. Johnson is scheduled to tell Parliament how his Conservative government will raise billions to fund the care millions of Britons need in the final years of their lives. That burden currently falls largely on individuals, who often have to deplete their savings or sell their homes to pay for care. One in seven people ends up paying more than 100,000 pounds ($138,000), according to the government, which calls the cost of care “catastrophic and often unpredictable.” Meanwhile, funding care for the poor who can’t afford it is placing a growing burden on overstretched local authorities. Johnson has been tight-lipped about his plans, which are being unveiled to the Cabinet on Tuesday morning before he makes a statement in the House of Commons. But the prime minister said late Monday he would “not duck the tough decisions needed.” He is expected to announce an increase in National Insurance payments made by working-age people to fund care and the broader National Health Service, which has been put under immense strain by the coronavirus pandemic. That would break the firm promise in Johnson’s 2019 election platform not to hike personal taxes. Breaking promises is hardly novel for politicians, but those enshrined in British parties’ election manifestos have long been considered binding on governments. Johnson’s rumored plan has alarmed many Conservative lawmakers — both because it involves breaking a firm election commitment, and because the burden would fall on working-age people and not retirees. Jake Berry, one of a crop of Conservative lawmakers representing northern England seats won from the Labour Party with promises of investment and new jobs, said the proposed plan would help affluent, older voters at the expense of younger, poorer ones. And William Hague, a former Conservative leader, said breaking an election promise would be a “loss of credibility when making future election commitments, a blurring of the distinction between Tory and Labour philosophies, a recruiting cry for fringe parties on the right, and an impression given to the world that the U.K. is heading for higher taxes.” Attempts to reform the care system have stymied British governments. Johnson’s predecessor, Theresa May, campaigned in a 2017 election on a plan to cut benefits to retirees and change the way they pay for long-term care. The idea was quickly dubbed a “dementia tax” by opponents, and May ended up losing her majority in Parliament.

NASA confirmed Monday that its Perseverance Mars rover succeeded in collecting its first rock sample for scientists to pore over when a future mission eventually brings it back to Earth. “I’ve got it!” the space agency tweeted, alongside a photograph of a rock core slightly thicker than a pencil inside a sample tube.  The sample was collected on September 1, but NASA was initially unsure whether the rover had successfully held onto its precious cargo, because initial images taken in poor light were unclear. After taking a new photo so mission control could verify its contents, Perseverance transferred the tube to the rover’s interior for further measurements and imaging, then hermetically sealed the container. “This is a momentous achievement, and I can’t wait to see the incredible discoveries produced by Perseverance and our team,” NASA administrator Bill Nelson said in a statement. Thomas Zurbuchen, associate administrator for science, likened the achievement to the first samples of rock taken from the Moon, which are still invaluable to researchers today. Perseverance’s sampling and caching system is the most complex mechanism ever sent to space, with more than 3,000 parts.  Its first target was a briefcase-sized rock nicknamed “Rochette” from a ridgeline that is particularly interesting from a geological perspective as it contains ancient layers of exposed bedrock. Perseverance uses a drill and a hollow coring bit at the end of its 2-meter-long (7-foot-long) robotic arm to extract samples. Perseverance landed on an ancient lakebed called the Jezero Crater in February, on a mission to search for signs of ancient microbial life using a suite of sophisticated instruments mounted on its turret. It is also trying to better characterize the red planet’s geology and past climate. The first part of the rover’s science mission, which will last hundreds of sols or Martian days, will be complete when it returns to its landing site.  By then, it will have traveled somewhere between 2.5 and 5 kilometers (1.6 and 3.1 miles) and may have filled up to eight of its 43 sample tubes. It will then travel to Jezero Crater’s delta region, which might be rich in clay minerals. On Earth, such minerals can preserve fossilized signs of ancient microscopic life. Eventually NASA wants to send back the samples taken by the rover in a joint mission with the European Space Agency, sometime in the 2030s. Its first attempt at taking a sample in August failed after the rock was too crumbly to withstand the robot’s drill.
