Top officials tapped with developing, approving and distributing COVID-19 vaccines say they're on track to begin distributing the first doses in the coming weeks and plan to vaccinate 100 million Americans by the end of February.In a press conference on Wednesday, Health and Human Services Director Alex Azar said the FDA would meet on Dec. 10 regarding Pfizer's vaccine candidate and on Dec. 17 regarding Moderna's vaccine candidate. The agency is currently reviewing both for Emergency Use Authorization.Both companies have been manufacturing doses of their candidate for several months in the hopes of ramping up supply in case of approval. Hundreds of thousands of doses of both doses will be ready for delivery as soon as approval is granted.Dr. Moncef Slaoui, Operation Warp Speed's chief advisor, stressed that the data from the vaccine trials are "clear" and shows both candidates to be safe and effective.According to Gen. Gus Perna, the operation's chief operating officer, the Department of Defense is prepared to deliver several million doses of both Pfizer and Moderna's vaccine upon approval. He said Wednesday that states are required to submit their "microplans" for Pfizer vaccine delivery to the Pentagon by the end of the week, and for the Moderna vaccine by the end of next week."The states know their populations the best," Perna said.Both Moderna's and Pfizer's vaccine candidates require two shots that need to be taken 28 days apart, and both vaccines need to be stored at ultra-cold temperatures before use.Slaoui said Wednesday that government officials expect 20 million Americans to be vaccinated by the end of December and that they project 100 million Americans will be vaccinated by the end of February.On Tuesday, an FDA panel recommended that health care workers and patients in long-term health facilities would be the first to receive the vaccine. Experts believe the vaccine will be available to everyone who wants it by spring 2021.Slaoui said Wednesday that government officials expect 20 million Americans to be vaccinated by the end of December and that they project 100 million Americans will be vaccinated by the end of February.Slaoui added that a one-shot vaccine candidate produced by Johnson & Johnson and a vaccine being developed by AstraZeneca could reach efficacy thresholds by the end of the month and that their approval would improve supply.Also on Wednesday, Azar stressed that new antibody treatments for COVID-19 are now available to any patients older than 65 who are not in the hospital. He also urged anyone who has recovered from COVID-19 in the last three months to donate their blood plasma to aid in those antibody treatments.The press conference was held the same day that officials in the United Kingdom granted emergency approval for the Pfizer vaccine. 2832

TRAVERSE CITY, Mich. (AP) — The Trump administration plans to lift endangered species protections for gray wolves across most of the nation by the end of the year. “We’re working hard to have this done by the end of the year and I’d say it’s very imminent,” Aurelia Skipwith, the director of the U.S. Fish and Wildlife Service, told The Associated Press in a phone interview Monday.More than 6,000 wolves now roam portions of the western Great Lakes and northern Rocky Mountains. The Fish and Wildlife Service last year proposed dropping the wolf from the endangered list in the lower 48 states, exempting a small population of Mexican wolves in the Southwest. It was the latest of numerous attempts to return management authority to the states — moves that courts have repeatedly rejected after opponents filed lawsuits.Director Skipwith told The Associated Press in a phone interview that the administration also is pushing ahead with a rollback of protections for migratory birds despite a recent setback in federal court. 1033

There's a new app out there that's promises to help people check for skin cancer. It's called Miiskin.It's the first app to use artificial intelligence to do full-body skin mapping. It also uses augmented reality to track how moles, freckles and skin change over time.Doctors say apps like these can actually help during this pandemic.“That has led to a significant decrease in visits for screening such as colon cancer, lung cancer, and skin cancer is of course one of those that actually is affected by the pandemic,” said Dr. Arturo Loaiza-Bonilla with Cancer Treatment Centers of America.When doctors and patients are dealing with cancer, time is of the essence.Tools like this app don't replace doctor's visits, but they can help with early detection.“One month of losing a cancer that was just newly found is almost a 10% increase in mortality, so if the screening comes a year later when the cancer is already starting, then we are in a pretty dark situation,” said Loaiza-Bonilla.Doctors at the Cancer Treatment Centers of America say that while the apps shouldn't replace a full physical assessment, they can be used as an additional tool to track new moles and see how certain things develop.If you are at a higher risk for skin cancer and want to use one of these apps, it's important that you do so under doctor supervision.These apps are still not considered a medical device.Doctors hope these tools can eventually be paired with medical records, so patients can be empowered by knowing more about their own health. 1537

TOKYO (AP) — The five Olympic rings are back in Tokyo Bay. The rings were removed for maintenance four months ago shortly after the Tokyo Olympics were postponed until next year because of the COVID-19 pandemic. The rings are positioned on a barge and stand about 15 meters tall and 33 meters in length — about 50 feet tall and 100 feet in length. The Olympic rings will be lighted at night and are situated in the shadow of Tokyo's famous Rainbow Bridge. The Olympics are to open on July 23, 2021, followed by the Paralympics on Aug. 24. Organizers are confident that 15,400 Olympic and Paralympic athletes can safely enter Japan during the pandemic. 659
