WASHINGTON, D.C. – Dr. Anthony Fauci said Tuesday that he’s optimistic that the United States will have millions of coronavirus vaccines ready by the end of the year. “By the beginning of 2021, we hope to have a couple of hundred million doses,” said Fauci, the director of the National Institute of Allergy and Infectious Diseases and member of the White House Coronavirus Task Force. Fauci made the comment during an interview with the American Medical Association and added that there are four or five trials underway for vaccine candidates to combat the COVID-19 pandemic. Fauci also said Phase III trials for a vaccine candidate developed by Moderna are expected to start in early July and another candidate from AstraZeneca is proceeding on a similar track. "I'm cautiously optimistic that with the multiple candidates that we have with different platforms, that we're going to have a vaccine that shows a degree of efficacy that would make it deployable," said Fauci. 987

We wish this week had never ended.Nothing was better than voting for our favorite ball of fur day after day. But Fat Bear Week is over and a winner has been named: 435 Holly, you glorious creature, the crown is yours."She is fat. She is fabulous," Alaska's Katmai National Park and Preserve, which created the competition five years ago, wrote. "All hail Holly whose healthy heft will help her hibernate until the spring. Long live the Queen of Corpulence."And we gotta give it to her, 435 Holly really packed on the pounds before hibernation. In just a little over two months, she completely transformed.What just happened?Let's backtrack.Fat Bear Week is an annual competition, held by the Alaskan park, to crown the fattest bear of the state's Brook River. The winner is picked with the help of online voters.The area's chunkiest bears competed in tough head-to-head matches until Tuesday. The winner of each round was determined by the number of votes they garnered, and then moved on to the next round to face their next competitor.And if you're asking if there really were other contenders, the answer is yes. There was a tournament bracket full of them.Are these bears OK with us calling them fat?Yes! They strive for it."There is no shame in winning this contest as large amounts of body fat in brown bears is indicative of good health and strong chances of survival," the National Park Service said in a news release.Alaska's brown bears are the largest brown bears in the world and eat up to 90 pounds of food each day, including other smaller mammals, salmon, berries, flowers and herbs."During winter hibernation, which can last for up to half of the year in their den, a bear could lose up to one third of its body mass. In preparation, the bears are entering hyperphagia this time of year, a state in which they eat nearly non-stop," NPS said.Male brown bears weigh anywhere from 600 to 900 pounds and by the time they go into hibernation, can jump up to a staggering 1,000 pounds, NPS said. Adult females usually weigh about a third less. The bears often get so big, that they have to dig a hole to stuff their belly in when they lay down to rest.How can you protect these tubby tummies?Take care of your surroundings.As a friendly reminder, the park said: "Fat bears only exist because of clean water and healthy ecosystems."Climate change, for example, poses a big threat to these glorious creatures.As the sea ice melts and polar bears find themselves on land more often, they begin to compete with brown bears for food."Such changes in food selection can result in large ecosystem changes as species adapted to be prey no longer have population control from predators, and other species suffer reduced populations due to additional predation," NPS said. 2784

US Customs and Border Protection will not vaccinate migrants, even though three children who had been in US custody died after contracting the flu.The cases all occurred since December."In general, due to the short-term nature of CBP holding and the complexities of operating vaccination programs, neither CBP nor its medical contractors administer vaccinations to those in our custody," according to a statement Tuesday from CBP.Migrants are supposed to held in CBP custody for 72 hours or less, but often remain there for longer.After leaving CBP custody, children without parents are sent into the care of the US Department of Health and Human Services, where flu vaccines are distributed, according to Evelyn Stauffer, a spokeswoman for the Office of Refugee Resettlement, a part of HHS.Public health experts had strong reactions to CBP's statement, saying the department should be able to vaccinate migrants, even if they're in CBP custody for only a few days."I think their answer is completely inappropriate," said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University and an adviser the US Centers for Disease Control and Protection. "They ought to be able to do this. They create facilities that encourage the spread of infectious agents, with flu at the top of the list."Flu activity in the United States typically begins to increase around October and many US pharmacies already have flu vaccines available.Children younger than 5, and especially those younger than 2, are at high risk of serious flu-related complications, according to the CDC. Flu seasons vary in severity, but thousands of children are hospitalized each year related to the flu, and some children die. A flu vaccine offers the best defense against getting flu and spreading it to others, the CDC said.Concern about contagious diseasesOn August 5, two members of Congress 1891
