British officials have authorized a COVID-19 vaccine for emergency use, greenlighting the world’s first shot against the virus that’s backed by rigorous science and taking a major step toward eventually ending the pandemic. The go-ahead Wednesday for the vaccine developed by American drugmaker Pfizer and Germany’s BioNTech comes as the virus surges again in the United States and Europe, putting pressure on hospitals and morgues in some places and forcing new rounds of restrictions that have devastated economies. The Medicines and Healthcare Products Regulatory Agency recommended the vaccine could be used after it reviewed the results of clinical trials that showed the vaccine was 95% effective overall — and that it also offered significant protection for older people.“Help is on its way,″ British Health Secretary Matt Hancock told the BBC. “We now have a vaccine. We’re the first country in the world to have one formally clinically authorized but, between now and then, we’ve got to hold on, we’ve got to hold our resolve.”Hancock later added that the country expects to receive the first shipment of 800,000 doses “within days″ and will begin distributing shots soon afterward.According to The Associated Press, England will first distribute the vaccine to people over the age of 80, people in long-term care facilities and health care workers. Government officials believe the vaccine will be widely available sometime in the spring.Pfizer and BioNTech have shattered records in developing their vaccine. The fastest a vaccine had previously been developed came in 1967 when the mumps vaccine was developed in four years. Pfizer and BioNTech have only been working on their COVID-19 vaccine candidate since the start of the pandemic. 1757

BRIDGEPORT, Calif. (AP) — Avalanche debris was spotted during a search for a missing Marine who failed to return from a backcountry skiing trip through the Sierra Nevada, California authorities said Sunday.First Lt. Matthew Kraft began trekking the rugged Sierra High Route on Feb. 23 and was scheduled to complete it Monday or Tuesday near Bridgeport, northeast of Yosemite National Park.The search on Sunday will primarily be air-based because "ground searching has proven to be too dangerous due to snow instability and avalanche concerns," the Inyo County Sheriff's office said in a statement. Much of the area was deemed impassable because of heavy snow and rock falls, the statement said.RELATED: Marine on ski trip to Sierras reported missingSearchers on Friday located a Jeep that Kraft parked at the start of his trip near Independence, about 130 miles (209 kilometers) south of Bridgeport, Inyo County Sheriff's spokeswoman Carma Roper said Saturday.Crews from local, state and federal agencies were searching a 400-square-mile (1,036-square-kilometer) area from Yosemite down to Sierra and Inyo National Forests and Kings Canyon National Park, Roper said.A series of winter storms has dumped record amounts of snow in the Sierra and led to avalanche warnings in the backcountry.Kraft is an infantry officer who received survival training in the field, military officials said. 1395

BOSTON (AP) — A California real estate developer was sentenced Friday to one month in prison for paying ,000 to cheat on his daughter's college entrance exam.Robert Flaxman, 63, of Los Angeles, was sentenced in Boston's federal court after pleading guilty in May to a single count of fraud and conspiracy. He is the 10th parent to be sentenced in a widespread college bribery scheme.Authorities say Flaxman paid ,000 to have a test proctor feed his daughter answers on her ACT exam in 2016. She scored a 28 out of 36 on the test, placing her in the 89th percentile and improving 4 points over her previous score on the exam.RELATED: Father linked to University of San Diego pleads guilty in college admissions scandalFlaxman's daughter used the score to apply to several schools, including the University of San Diego, and ultimately enrolled at one of them, prosecutors said. They did not identify where she goes to college but said the school suspended her for a semester when the scheme was uncovered.In earlier court documents, the FBI also accused Flaxman of paying an admissions consultant 0,000 to fabricate application documents that were used to get his son into USD. Those allegations were not pursued, however, and they weren't included in Flaxman's plea agreement with prosecutors.Flaxman's lawyers say he agreed to the testing scheme because his daughter's test scores were too low to get into college. He wasn't trying to get her into an elite or exclusive school, they said, and he wasn't chasing social status "ego gratification."RELATED: Felicity Huffman turns herself in, begins 14-day jail sentenceProsecutors said he deserved prison time, nonetheless, because his daughter ended up getting involved in the scheme, and because Flaxman sought a tax deduction for the ,000 bribe, which was funneled through a sham charity.Flaxman is the owner and CEO of Crown Realty & Development Inc., a real estate firm that operates and develops commercial property in California, Arizona, North Carolina and elsewhere. Its website says it manages nearly billion in property.More than 50 people have been charged in the scheme, which involves wealthy and famous parents accused of paying bribes to rig their children's test scores or to get them admitted to elite universities as recruited athletes.RELATED: Cost of college: What parents and students can expect to pay for admissionA total of 15 parents have pleaded guilty, while 19 are contesting the charges. Trials are expected to begin in 2020. 2530
