Pfizer formally asked U.S. regulators Friday to allow emergency use of its COVID-19 vaccine, starting the clock on a process that could bring limited first shots as early as next month and eventually an end to the pandemic 맥스카지노� but not until after a long, hard winter.The action comes days after Pfizer Inc. and its German partner BioNTech announced that its vaccine appears 95% effective at preventing mild to severe COVID-19 disease in a large, ongoing study.The companies said that protection plus a good safety record means the vaccine should qualify for emergency use authorization, something the Food and Drug Administration can grant before the final testing is fully complete. In addition to the FDA submission, they have already started 맥스카지노�rolling맥스카지노� applications in Europe and the U.K. and intend to submit similar information soon.With the coronavirus surging around the U.S. and the world, the pressure is on for regulators to make a speedy decision.맥스카지노�Help is on the way,맥스카지노� Dr. Anthony Fauci, the top U.S. infectious disease expert said on the eve of Pfizer's announcement, adding that it's too early to abandon masks and other protective measures. 맥스카지노�We need to actually double down on the public health measures as we're waiting for that help to come.맥스카지노�Friday맥스카지노�s filing sets off a chain of events as the FDA and its independent advisers debate if the shots are ready. If so, still another government group will have to decide how the initial limited supplies are rationed out to anxiously awaiting Americans.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 much vaccine is available and when is a moving target, but initial supplies will be scarce and rationed. Globally, Pfizer has estimated it could have 50 million doses available by year's end.About 25 million may become available for U.S. use in December, 30 million in January and 35 million more in February and March, according to information presented to the National Academy of Medicine this week. Recipients will need two doses, three weeks apart. The U.S. government has a contract to buy millions of Pfizer-BioNTech doses, as well as other candidates that pan out, and has promised shots will be free.Not far behind is competitor Moderna Inc.맥스카지노�s COVID-19 vaccine. Its early data suggests the shots are as strong as Pfizer맥스카지노�s, and that company expects to also seek emergency authorization within weeks.Here맥스카지노�s what happens next:MAKING THE DATA PUBLICThe public맥스카지노�s first chance to see how strong the evidence really is will come in early December at a public meeting of the FDA맥스카지노�s scientific advisers.So far, what's known is based only on statements from Pfizer and BioNTech. Of 170 infections detected to date, only eight were among people who'd received the actual vaccine and the rest had gotten a dummy shot. On the safety side, the companies cite results from 38,000 study participants who've been tracked for two months after their second dose. That's a milestone FDA set because historically, vaccine side effects don't crop up later than that.맥스카지노�We맥스카지노�ll drill down on these data,맥스카지노� said FDA adviser Dr. Paul Offit of the Children맥스카지노�s Hospital of Philadelphia.Think of it like science on trial. A few days before the meeting, the FDA will release its own internal analysis. That sets the stage for the advisers맥스카지노� daylong debate about any signs of safety concerns and how the new vaccine technology works before rendering a verdict.They맥스카지노�ll recommend not just whether FDA should allow broader use of the vaccine generally but if so, for whom. For example, is there enough proof the vaccine works as well for older, sicker adults as for younger, healthier people?There맥스카지노�s still no guarantee. 맥스카지노�We don맥스카지노�t know what that vote맥스카지노�s going to be,맥스카지노� said former FDA vaccine chief Norman Baylor.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EMERGENCY USE ISN맥스카지노�T THE SAME AS FULL APPROVALIf there's an emergency green light, 맥스카지노�that vaccine is still deemed investigational. It맥스카지노�s not approved yet,맥스카지노� Dr. Marion Gruber, chief of FDA맥스카지노�s vaccine office, told the National Academy of Medicine this week.That means anyone offered an emergency vaccination must get a 맥스카지노�fact sheet맥스카지노� describing potential benefits and risks before going through with the shot, she said.There will be a lot of unknowns. For example, the 95% protection rate is based on people who developed symptoms and then were tested for the virus. Can the vaccinated get infected but have no symptoms, able to spread the virus? How long does protection last? That맥스카지노�s why the 44,000-person study needs to keep running 맥스카지노� something difficult considering ethically, participants given dummy shots at some point must be offered a real vaccine, complicating the search for answers.맥스카지노�I'm curious," said Barry Colvin, 52, of White Plains, New York, who is taking part in that study at NYU Langone Health.But he's not in a great hurry to find out which group he's in. 맥스카지노�You need to hang in there for a while to understand and answer a lot of the other questions that remain unknown.맥스카지노�Additionally at least for now, pregnant women won't qualify because they weren't studied. Pfizer only recently began testing the vaccine in children as young as 12.A decision on Pfizer-BioNTech's vaccine won't affect other COVID-19 vaccine candidates in the pipeline, which will be judged separately.MANUFACTURINGBrewing a vaccine is more complex than typical drug manufacturing, yet the millionth dose to roll out of Pfizer맥스카지노�s Kalamazoo, Michigan, factory must be the same purity and potency as every dose before and after.That means the FDA decision isn맥스카지노�t just based on study data, but on its determination that the vaccine is being made correctly.The Pfizer-BioNTech vaccine 맥스카지노� and Moderna's shots 맥스카지노� are made with brand-new technology. They don맥스카지노�t contain the actual coronavirus. Instead, they맥스카지노�re made with a piece of genetic code for the 맥스카지노�spike맥스카지노� protein that studs the virus.That messenger RNA, or mRNA, instructs the body to make some harmless spike protein, training immune cells to recognize it if the real virus eventually comes along.GETTING INTO PEOPLE맥스카지노�S ARMSAnother government group 맥스카지노� advisers to the Centers for Disease Control and Prevention 맥스카지노� decides who is first in line for scarce doses. Health and Human Services Secretary Alex Azar said he hopes that decision can be made at the same time as FDA맥스카지노�s.The Trump administration맥스카지노�s Operation Warp Speed has worked with states to line up how many doses they맥스카지노�d need to cover the populations offered vaccine first.Pfizer will ship those supplies as ordered by the states 맥스카지노� only after FDA gives the OK.Company projections of how much it will ship each month are just predictions, Baylor warned.맥스카지노�It맥스카지노�s not like a pizza,맥스카지노� he said. Manufacturing is so complex that 맥스카지노�you don맥스카지노�t necessarily end up with what you thought.맥스카지노�___AP video journalist Kathy Young contributed to this report.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute맥스카지노�s Department of Science Education.
