The first experimental COVID-19 vaccine in the U.S. is on track to begin a huge study next month to prove if it really can fend off the coronavirus, while hard-hit Brazil is testing a different shot from China.Where to do crucial, late-stage testing and how many volunteers are needed to roll up their sleeves are big worries for health officials as the virus spread starts tapering off in parts of the world.Moderna Inc. said Thursday the vaccine it is developing with the National Institutes of Health will be tested in 30,000 people in the U.S. Some will get the real shot and some a dummy shot, as scientists carefully compare which group winds up with the most infections.With far fewer COVID-19 cases in China, Sinovac Biotech turned to Brazil, the epicenter of Latin America’s outbreak, for at least part of its final testing. The government of S?o Paulo announced Thursday that Sinovac will ship enough of its experimental vaccine to test in 9,000 Brazilians starting next month.If it works, “with this vaccine we will be able to immunize millions of Brazilians,” said S?o Paulo′s Gov. Joao Doria.Worldwide, about a dozen COVID-19 potential vaccines are in early stages of testing. The NIH expects to help several additional shots move into those final, large-scale studies this summer, including one made by Oxford University that’s also being tested in a few thousand volunteers in Brazil.There’s no guarantee any of the experimental shots will pan out.But if all goes well, “there will be potential to get answers” on which vaccines work by the end of the year, Dr. John Mascola, who directs NIH’s vaccine research center, told a meeting of the National Academy of Medicine on Wednesday.Vaccines train the body to recognize a virus and fight back, and specialists say it’s vital to test shots made in different ways — to increase the odds that at least one kind will work.Sinovac’s vaccine is made by growing the coronavirus in a lab and then killing it. So-called “whole inactivated” vaccines are tried-and-true, used for decades to make shots against polio, flu and other diseases — giving the body a sneak peek at the germ itself — but growing the virus is difficult and requires lab precautions.The vaccine made by the NIH and Moderna contains no actual virus. Those shots contain the genetic code for the aptly named “spike” protein that coats the surface of the coronavirus. The body’s cells use that code to make some harmless spike protein that the immune system reacts to, ready if it later encounters the real thing. The so-called mRNA vaccine is easier to make, but it’s a new and unproven technology.Neither company has yet published results of how their shots fared in smaller, earlier-stage studies, designed to check for serious side effects and how well people’s immune systems respond to different doses.Even before proof that any potential vaccine will work, companies and governments are beginning to stockpile millions of doses so they can be ready to start vaccinating as soon as answers arrive.In the U.S., a program called “Operation Warp Speed” aims to have 300 million doses on hand by January. Under Brazil’s agreement with Sinovac, the Instituto Butantan will learn to produce the Chinese shot.___AP journalist Marcelo Silva de Sousa contributed to this report.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The Environmental Protection Agency has handed documents to Congress that show new travel expenses from agency administrator Scott Pruitt, totaling some ,000 in hotel stays and air travel, The Washington Post reported Tuesday.The documents, which were requested by House Oversight Committee Chairman Trey Gowdy and obtained by the Post, reportedly show that Pruitt traveled on government business dozens of time on first-class and domestic flights from August 2017 through February 2018.The reported expenses include a four-day, ,631 trip to Morocco in December, a series of first-class flights following Hurriciane Harvey totaling ,330, and a two-day domestic trip for media interviews and a visit to Florida that amounted to ,767. Pruitt's travel expenses listed in the records reportedly do not include the costs of his security team or aides who travel with him.The EPA justified the travel spending as necessary to ensure Pruitt's security."EPA's Protective Service Detail identified specific ongoing threats associated with Administrator Pruitt's travel and shifted his class based on certain security protocols that require him to be near the front of the plane," said Jahan Wilcox, a spokesperson for the agency.Previously, CNN reported that from June through August 2017, the EPA justified several expensive charter flights for Pruitt -- including a ,000 bill for a business trip around his home state.In late August, the EPA inspector general announced it would investigate Pruitt's travel practices. Since beginning the probe, the IG has twice expanded its scope, which now encompasses all of Pruitt's 2017 taxpayer-funded travel.According to an earlier Post analysis of other EPA records, Pruitt's travel choices distinguish him from his predecessors in that he brings a larger group of aides with him on trips, he usually flies first or business class on international and domestic trips, and he often flies Delta Airlines even though the government has contracts with certain airlines on specific routes.In response to the travel probes, earlier this month Pruitt said he'll be seeking alternative accommodations -- including potentially flying in coach class -- on his "very next flight."Other Trump administration Cabinet secretaries have attracted scrutiny of their travel spending, including Interior Secretary Ryan Zinke, Veterans Affairs Secretary David Shulkin, Treasury Secretary Steve Mnuchin and former Health and Human Services Secretary Tom Price, who resigned after using private planes for multiple government business trips.Pruitt has also been under scrutiny for the costs the agency has accrued changing EPA headquarters, including a ,000 secure phone booth for Pruitt's calls.Other Cabinet members' spending for office renovations has been criticized recently. Zinke's office doors were to be replaced to the the tune of nearly 9,000. The department later said it would obtain the doors at a reduced price. And last month, Housing and Urban Development Secretary Ben Carson withdrew his request for a ,000 dining room set for his office. He told Congress this week that the redecorating decision was left to his wife.  3185

The conversation around wearing different protective gear is expanding. In particular, face shields.Teachers recently asked the nation’s top infectious disease expert, Dr. Anthony Fauci, about it and he said, “if you can get one, it’s not a bad idea.”Fauci went on to say that a shield shouldn't necessarily be worn in place of a mask, but more parents are considering the option for kids.“For some of the kids, a mask just isn't going to work. And in those cases, a face shield can be considered, but I think it needs to be understood that that’s not the default,” said Dr. Preeti Malani with the Infectious Diseases Society of America.Infectious disease experts say there just isn't enough data yet on how much protection a face shield provides.One study found it did significantly reduce the number of inhaled droplets, but cloth masks are also about protecting others. Shields were not as sure to do that as well.“If you're wearing a shield, the respiratory secretions that might be coming from your mouth or nose are not going to be as well contained,” said Malani.In the health care setting, face shields are used primarily to prevent splashing in the eyes.Malani offered this advice about finding the right shield.“It’s important that it’s long enough to really protect the whole face and that it wraps around fully and that it fits well up at the forehead,” said Malani.Companies, including Apple, Nike, General Motors, and John Deere have all started producing face shields.In a JAMA Network open viewpoint, it was pointed out that face shields have some advantages over masks. They can be reused indefinitely, they are easier to clean, they are comfortable, and they help prevent touching of the face. 1719

The devastation left by Hurricane Michael in several states is still coming into focus, with coastal Florida cities destroyed beyond recognition, and homes, businesses and agriculture torn or swamped from Georgia to Virginia.More than 1 million customers were left without electricity, and emergency officials have no access to many towns. The US death toll has risen to at least 17 -- including five in Virginia and eight in Florida -- and it's expected to climb."I expect the fatality count to rise today and tomorrow as we get through the debris," Federal Emergency Management Agency Administrator Brock Long said Friday morning.Michael, which smacked Florida's Panhandle as one of the most powerful hurricanes to hit the United States, left Virginia's coast as a post-tropical low early Friday -- and its trail of destruction will take weeks to take into account.Aerial footage shows coastal cities in the Panhandle, like Mexico Beach, wiped out. Search teams used dogs as they combed the area for people killed or trapped in debris.One death was reported in Mexico Beach -- that of an elderly man found alone, Mayor Al Cathey said.City manager Tanya Castro said Mexico Beach won't be up and running for 12-18 months and advised people who evacuated not to return.Dawn Vickers rode out the storm in Mexico Beach, but her house and vehicles were demolished. Without cell phone service or transportation, she has been taking shelter in one of the few condos left standing, invited by someone she met at what's left of a gas station."This has been the worst nightmare I've ever been through in my life," she told CNN on Friday.A psychiatric hospital in Florida is isolated after downed trees blocked roads around Chattahoochee, and a tree caused a water line to break. The facility is running on power generators, and helicopters have delivered food and water, the state's Department of Children and Families said. 1938

The decision to reintroduce gray wolves in Colorado will be decided by the people, and both sides of the issue say the decision will impact the entire country.“Only in 2020, the weird year that we are having would Colorado be voting to introduce a species that’s already here in Colorado,” said Shawn Martini, the vice president of advocacy for the Colorado Farm Bureau.“The western part of Colorado is primarily owned, and majority-owned, by the people as public lands,” said Rob Edward, who is part of the Rocky Mountain Wolf Project. “We all have interests on what happens on our public lands.”For centuries, the gray wolf roamed North America in large populations. But in the 1900s, the wolves were nearly hunted out of existence.The wild wolves haven’t lived in Colorado since 1940, and the U.S. Fish and Wildlife Service classified the animal as an endangered species in 1978.“They are the missing link in the Rocky Mountain chain,” Edward said. “From the high arctic to New Mexico, we can re-establish a population of wolves again by reintroducing wolves to western Colorado. The presence of wolves on those wild landscapes is important for the long-term health of those landscapes.”With Proposition 114 in Colorado, the people will be able to vote in November on whether this will become a reality. This is something that has never happened in the nation’s history.“Wolves are already all over the place,” Martini said. “They’ve come down from Wyoming and Montana through a natural process. We’re asking voters to say no to this ballot initiative, because it makes something a natural process into a political one.”Having people vote on this is something Martini is strongly against.“So, this the first time a species would be introduced into a state via a ballot measure,” Martini said. “The reason it’s never been done before because it’s a really bad idea to make a scientific process a political one. The Colorado Parks and Wildlife and biologists should be the ones making this decision, not voters who don’t always have access to the info and are not biologists and who don’t do this for a living.”The main reason wolf advocates like Edwards want to re-introduce wolves to the area is that they believe it could improve the ecosystem. In 1995, the gray wolf was reintroduced into the greater Yellowstone ecosystem to help manage the high population of elk. But that decision wasn’t voted on by the people.Biologists came up with a plan and brought it to Congress. After years of public comment, the secretary of the interior finally signed off on the project.“Colorado is not Yellowstone,” Martini said. “Yellowstone is subject to a ton of environmental regulations, so the people managing the area don’t have the same tools as Colorado does.”Regardless of what side people are on this issue, both sides agree that this a historic ballot measure that could change the course of the country ecologically and politically. 2941
