Moderna announced on Thursday that it had enrolled 30,000 participants in its Phase 3 COVID-19 vaccine trial, with more than 11,000 of those participants from communities of color.More than 25,650 participants have already received their second vaccination, the company said in a press release.The company added that the study also includes 7,000 participants over the age of 65.“Completing enrollment of the Phase 3 COVE study is an important milestone for the clinical development of mRNA-1273, our vaccine candidate against COVID-19," said Stéphane Bancel, Chief Executive Officer of Moderna in the news release. "We are indebted to all of the participants in the study. We would also like to thank the investigators and our partners at clinical trial sites, including our partners from PPD and the NIH, as well as the dedicated Moderna team for their support in completing enrollment. Moderna is committed to rigorous scientific research and the highest data quality standards. We will continue to work in collaboration with regulators to advance mRNA-1273, which we hope will help defeat the COVID-19 pandemic.”CNN reported that for Moderna to apply to the FDA for emergency use authorization, the following three things need to happen:53 of the 30,000 participants would need to become sick with COVID-19, which is expected to occur in the second half of November.40 of the 53 participants who do become ill with COVID-19 need to have received the placebo, which would show that the vaccine is 75% effective.Make sure enough time has passed to see if participants develop side effects.According to CNN, Moderna is the first company to start US clinical trials of a COVID-19 vaccine. 1696

Money has never mattered that much to David Hockney, as long as he has enough to continue working. But equally, he's also always had a good memory for figures -- for the pounds, shillings and pence. As a student at London's Royal College of Art, he remembers selling a drawing to a friend and fellow student, the American painter Ron Kitaj, for a princely £5. It meant that he could buy cigarettes in packs of 20. He sold another early painting, "Adhesiveness" (1960), to photographer Cecil Beaton for £40. That meant he could begin planning to travel abroad.As it happens, Hockney also has a clear memory of what "Portrait of an Artist (Pool with Two Figures)" originally fetched shortly after he painted it. On Thursday, at a Christie's auction in New York, the painting was sold for .3 million, an auction record for a living artist. But back in 1972, his New York dealer sold it for just ,000.For Hockney, the memory is still bittersweet. He felt ripped off. Last year, at his studio in the Hollywood Hills, he told CNN, "I thought it was a lot of money at the time, but within six months, it was sold again for ,000."After the sale, Hockney's American dealer, Andre Emmerich, "realized the pictures (in the show) were underpriced. A lot had been underpriced." But by then, it was too late. And so, as is often the case in the art market, someone other than the artist made a swift and substantial profit.More is known about the creation of "Portrait of an Artist (Pool with Two Figures)" than virtually any other single Hockney painting. The 1974 biopic "A Bigger Splash" chronicled its creation, and Hockney himself wrote about the painting in detail in 1988's "David Hockney by David Hockney: My Early Years.""A Bigger Splash" was shot from 1971 to 1973 by British director Jack Hazan, who was given special access to Hockney, then living and working in London's Notting Hill, and his inner circle. A mix of fact and fiction, it centers on the painful unraveling of Hockney's five-year relationship with a young American artist, Peter Schlesinger.Hockney told CNN the painting was inspired by an accidental juxtaposition of "two photographs on my studio floor, one of the Peter and another of a swimmer, and they were just lying there and I put them together." In his 1988 memoir, "David Hockney by David Hockney: My Early Years," he wrote: "The idea of painting two figures in different styles appealed so much that I began the painting immediately."He worked on the picture for six solid months. The standing figure was always Peter Schlesinger. According to his official biographer, Christopher Simon Sykes, Hockney painted the swimmer first but then coated the canvas with a preparatory gesso, which prevented him from altering the position of the pool or the standing figure. It was a mistake.Hockney gradually realized the painting -- in particular, the angle of the swimming pool -- just wasn't right. He wrote that, "The figures never related to one another nor to the background. I changed the setting constantly from distant mountains to a claustrophobic wall and back again to mountains. I even tried a glass wall."Realizing the futility of his efforts, Hockney abandoned that effort and, reinvigorated, started the painting all over again. He chose a new setting, a pool by a house in the south of France that belonged to British film director Tony Richardson. He took two models with him: a photographer named John St. Clair and Mo McDermott, his studio assistant.He took hundreds of photos of the two. St. Clair, the submerged swimmer, dived into the pool in his white briefs so many times that he eventually cracked his head on the bottom and had to stop. McDermott acted as Schlesinger's stand-in, wearing his reddish pink jacket by the pool. Back in London, Hockney persuaded Schlesinger to pose for him early one morning in Hyde Park for yet more photos.Once back at his Notting Hill studio, Hockney painted for 18 hours a day on a canvas seven feet by 10. At one point, Hockney is filmed taking a Polaroid of the unfinished painting. At another moment, he paints in Schlesinger's brown hair with a long brush. "I must admit that I loved working on that picture, working with such intensity," he later told biographer Sykes. "It was marvelous doing it, really thrilling."While he spent six months of the first version, the final "Portrait of an Artist (Pool with Two Figures)" was finished in just two weeks, to meet a deadline for a New York show in May 1972. In "A Bigger Splash," Hockney, with his trademark bleached blond hair and black, owlish spectacles, stands in bright red braces and a bow tie, carefully checking out how the painting was hung and lit in the show. It was the star exhibit, perhaps an expression of Hockney's personal loss and his acceptance that his long affair with Schlesinger was finally over.But as we now know, all this wasn't without a sense of Hockney feeling cheated by what happened next. An American, apparently alerted by a British dealer, just came in off the street and bought it. The dealer then promptly took it to an art fair in Germany and sold it to a London collector for nearly three times the price. As he wrote in "My Early Years": "Within a year people had made far more on that picture than Kasmin (John Kasmin, his London dealer), Andre (Emmerich, his New York dealer) or I had. Considering the effort and trouble and everything that had gone into it, it seemed such a cheap thing to do."We can only imagine how Hockney will feel after this sale, when the painting he worked so hard on has sold for more than 5,000 times its original price. The current seller and the auction house will no doubt profit, but, as a Christie's spokesperson confirmed, "the artist will not be financially benefiting."Christie's hasn't named the seller, but he's believed to be British businessman Joe Lewis, who has famously collected postwar British art for some time.At 81, Lewis happens to be the same age as Hockney. He also has a net worth of billion. 6042

Stamkos briefly played in Game 3 of the Stanley Cup Finals, and he even scored a goal in his short appearance.The NHL suspended its season on March 12 due to the coronavirus pandemic. After a nearly four-month hiatus, the NHL resumed action with a 24-team playoff held in two “hub” cities – Edmonton and Toronto.The entirety of the Stanley Cup Finals was played in Edmonton.Stepping up for the absent Stamkos, Nikita Kucherov and Brayden Point helped the Lightning to victory. Kucherov had a league-leading 32 points in the playoffs, followed by 31 points for Point.But it was defender Victor Hedman who won the the Conn Smythe Trophy for the playoff's most valuable player.The Lightning’s goalie, Andrei Vasilevskiy, also stepped up with an under 2 goals against average.The Lightning’s Stanley Cup victory avenged the ending to the Lightning’s 2019 season.
