With a coronavirus vaccine still months off, companies are rushing to test what may be the next best thing: drugs that deliver antibodies to fight the virus right away, without having to train the immune system to make them.Antibodies are proteins the body makes when an infection occurs; they attach to a virus and help it be eliminated. Vaccines work by tricking the body into thinking there’s an infection so it makes antibodies and remembers how to do that if the real bug turns up.But it can take a month or two after vaccination or infection for the most effective antibodies to form. The experimental drugs shortcut that process by giving concentrated versions of specific ones that worked best against the coronavirus in lab and animal tests.“A vaccine takes time to work, to force the development of antibodies. But when you give an antibody, you get immediate protection,” said University of North Carolina virologist Dr. Myron Cohen. “If we can generate them in large concentrations, in big vats in an antibody factory ... we can kind of bypass the immune system.”These drugs are believed to last for a month or more and could give quick, temporary immunity to people at high risk of infection, such as health workers and housemates of someone with COVID-19. If they proved effective and if a vaccine doesn’t materialize or protect as hoped, the drugs might eventually be considered for wider use, perhaps for teachers or other groups.They’re also being tested as treatments, to help the immune system and prevent severe symptoms or death.“The hope there is to target people who are in the first week of their illness and that we can treat them with the antibody and prevent them from getting sick,” said Dr. Marshall Lyon, an infectious disease specialist helping to test one such drug at Emory University in Atlanta.Having such a tool “would be a really momentous thing in our fight against COVID,” Cohen said.Vaccines are seen as a key to controlling the virus, which has been confirmed to have infected more than 20 million people worldwide and killed more than 738,000. Several companies are racing to develop vaccines, but the results of the large final tests needed to evaluate them are months away.The antibody drugs are “very promising” and, in contrast, could be available “fairly soon,” said Dr. Janet Woodcock, a U.S. Food and Drug Administration official who is leading government efforts to speed COVID-19 therapies. Key studies are underway and some answers should come by early fall.One company, Eli Lilly, has already started manufacturing its antibody drug, betting that studies now underway will give positive results.“Our goal is to get something out as soon as possible” and to have hundreds of thousands of doses ready by fall, said Lilly’s chief scientific officer, Dr. Daniel Skovronsky.Another company that developed an antibody drug cocktail against Ebola — Regeneron Pharmaceuticals Inc. — now is testing one for coronavirus.“The success with our Ebola program gives us some confidence that we can potentially do this again,” said Christos Kyratsous, a Regeneron microbiologist who helped lead that work.Regeneron’s drug uses two antibodies to enhance chances the drug will work even if the virus evolves to evade action by one.Lilly is testing two different, single-antibody drugs — one with the Canadian company AbCellera and another with a Chinese company, Junshi Biosciences. In July, Junshi said no safety concerns emerged in 40 healthy people who tried it and that larger studies were getting underway.Others working on antibody drugs include Amgen and Adaptive Biotechnologies. The Singapore biotech company Tychan Pte Ltd. also is testing an antibody drug and has similar products in development for Zika virus and yellow fever.“I’m cautiously optimistic” about the drugs, said the nation’s top infectious diseases expert, Dr. Anthony Fauci. “I’m heartened by the experience that we had with Ebola,” where the drugs proved effective.What could go wrong?— The antibodies may not reach all of the places in the body where they need to act, such as deep in the lungs. All the antibody drugs are given through an IV and must make their way through the bloodstream to wherever they’re needed.— The virus might mutate to avoid the antibody — the reason Regeneron is testing a two-antibody combo that binds to the virus in different places to help prevent its escape.Skovronsky said Lilly stuck with one antibody because manufacturing capacity would essentially be cut in half to make two, and “you will have less doses available.” If a single antibody works, “we can treat twice as many people,” he said.— The antibodies might not last long enough. If they fade within a month, it’s still OK for treatment since COVID-19 illness usually resolves in that time. But for prevention, it may not be practical to give infusions more often than every month or two.A San Francisco company, Vir Biotechnology Inc., says it has engineered antibodies to last longer than they usually do to avoid this problem. GlaxoSmithKline has invested 0 million in Vir to test them.Giving a higher dose also may help. If half of antibodies disappear after a month, “if you give twice as much, you will have two months’ protection,” Lilly’s Skovronsky said.— The big fear: Antibodies may do the opposite of what’s hoped and actually enhance the virus’s ability to get into cells or stimulate the immune system in a way that makes people sicker. It’s a theoretical concern that hasn’t been seen in testing so far, but large, definitive experiments are needed to prove safety.“As best as we can tell, the antibodies are helpful,” Lyon said.___Marilynn Marchione can be followed on Twitter: @MMarchioneAP___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

White House staff just got an email telling them not to come to work if they have symptoms. If they develop them, they’re told to go home and contact their primary care provider. “Staff should not go to the White House Medical Unit clinic for any Covid-19 testing inquiries.”— Kaitlan Collins (@kaitlancollins) October 5, 2020 334

While giving a daily briefing at a hospital near Miami, Florida Gov. Ron DeSantis was interrupted by a protester who called for DeSantis' resignation.Video from the press conference shows the protester yelling over DeSantis, accusing him of "falsifying information" and having "no plan" to combat the pandemic."Shame on you!" the protester said.He was later led out of the room by security. As guards grabbed him, the protester asked them to "social distance" and not touch him. The guards led him out of the media event anyway.DeSantis did not respond to the comments. 577

With a population density of six people per square mile, few places are quite as suited to ride out COVID-19 as Wyoming.But in the south-central part of the state, close to the Colorado border, sits a ranch that might offer the best accommodations of all.At ,000 per night, renting out Magee Homestead might not be for everyone, but for the clients it does attract, it offers an opportunity to quarantine with family while offering the ability to vacation with fly fishing, archery, and horseback riding.“The decision was either to open or not,” said ranch proprietor Jeremy Belnap. “Then, we slowly started to get inquiries for families wanting to get away.”Like so many businesses across the country, the ranch had to answer a difficult question during the months of March and April.“We had originally chosen to close the ranch for the season and open back up for the 2021 season,” said Belnap.With 7,500 acres of land to tend to and dozens of living spaces that require electricity, the prospect of closing was daunting and carried loads of overhead.“Financially, we suffer if we close the night with two or four guests on property,” Belnap said. “We have a staff of 45 dedicated people. We spend that much on labor in a day so it can cripple you.”As it was preparing to close, however, the ranch started getting calls from families, some of whom had stayed at Magee Homestead previously, that were interested in renting the entire ranch out.After some consideration, Belnap and the staff made the decision to switch their business model to accommodate the buyouts, allowing them to stay open while offering the families a chance to stay safe away from home.“It’s like we’re quarantining together,” said Belnap. “[It was] a light bulb moment. We took enough phone calls to say this could really make sense.”At capacity, the ranch can house up to 12 couples at a time. At approximately ,000 per guest per night, it requires a sold-out crowd on each night to reach its revenue ceiling, but Belnap says the buyouts offer more revenue with fewer question marks, and it is something they plan to continue once the worst of COVID-19 passes.“It’s very efficient,” said Belnap. “It’s a lot of fun having a family here for entire week, where you really get to know the family and the kids.” 2297

When you think of police officers, you may think of the badge or the local precinct may come to mind, but a lasso?“You got to have a lasso in a small town,” Sgt. Jace Peterson said with a laugh.Sgt. Peterson says it is an item he never leaves home without. Home is Nephi, Utah and it has been most of his life.“Oh, I was a good kid who got in very little trouble,” Peterson said.Nephi is a "blink and you miss it" stop along Interstate-15 between Salt Lake City and Las Vegas.Sgt. Peterson is just one of 10 full-time officers.“I just patrol all the corners of town, backstreets and the main thoroughfares,” he said.A disorderly conduct call sometimes comes in the form of a farm animal.“We’ve had cows and goats,” Peterson said. “I mean you name it and they run loose around here.”Sgt. Peterson knows he is just one call away from a surprise class reunion.“It makes it entertaining when you stop somebody you know or you’re on a call with somebody you went to high school with,” he said.Life moves at a slower pace in these parts. It is a stark contrast from what officers in major cities across the country are dealing with.“The rioting and the protest,” Sgt. Peterson said slowly shaking his head. “I mean, it starts to wear on you a little bit and know that other officers aren’t as lucky as we are.”The Nephi Chief of Police echoes those sentiments.“You know, the great thing is I had the big city policing experience when I was young,” said Chief Mike Morgan. “When I was young, I could get out and do the things that needed to get done and I was able to learn; that experience brought me here.”Like Peterson, Chief Morgan has come home.“There’s no place like home,” Chief Morgan said with a chuckle.The move from big city life means big changes.“There are no protests at all down here,” Chief Morgan said.The department is prepared for the day some of the bigger city issues may creep into town.“We’ve got all the equipment I could ever ask for and it’s such a great community,” Sgt. Peterson said.Even a worldwide pandemic is not affecting the small-town police force much.“I mean, we know it’s there and we know it’s just one bad day away, but until then, we’re just going to sort of enjoy it,” Sgt. Peterson said. 2231
