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.

When you think of infrastructure, you may think of the country’s roads and bridges. But some of America’s airports are in major need of improvements, like New York’s LaGuardia Airport.More than 2 million people take to the skies every single day in the United States, and most domestic travelers fly through LaGuardia—one of the busiest airports in the country.From appearance to efficiency, travelers say they expect more for their tax money.Almost exactly one year ago, New York Gov. Andrew Cuomo announced an million overhaul at the airport, stressing the importance of airport infrastructure as a whole. “You have beautiful airports being built all around the globe--Korea, Munich, Dubi, Hong Kong-- magnificent structures,” says Gov. Cuomo. “And for decades, this nation has done nothing.”The last major airport to be rebuilt in the U.S. was at the Denver International Airport more than 20 years ago. Now, LaGuardia is up next; improvements are already underway and expected to be done by 2021.Travelers say the improvements can’t come soon enough. 1070

  

With many teachers opting out of returning to the classroom because of the coronavirus, schools around the U.S. are scrambling to find replacements and in some places lowering certification requirements to help get substitutes in the door.Several states have seen surges in educators filing for retirement or taking leaves of absence. The departures are straining staff in places that were dealing with shortages of teachers and substitutes even before the pandemic created an education crisis.Among those leaving is Kay Orzechowicz, an English teacher at northwest Indiana’s Griffith High School, who at 57 had hoped to teach for a few more years. But she felt her school’s leadership was not fully committed to ensuring proper social distancing and worried that not enough safety equipment would be provided for students and teachers.Add the technology requirements and the pressure to record classes on video, and Orzechowicz said it “just wasn’t what I signed up for when I became a teacher.”“Overall, there was just this utter disrespect for teachers and their lives,” she said. “We’re expected to be going back with so little.” When school leaders said teachers would be “going back in-person, full throttle, that’s when I said, ‘I’m not doing it. No.’”Teachers in at least three states have died after bouts with the coronavirus since the start of the new school year. It’s unclear how many teachers in the U.S. have become ill with COVID-19, but Mississippi alone reported 604 cases among teachers and staff.In cases where teachers are exposed to the virus, they could face pressure to return to the classroom. The Trump administration has declared teachers to be “critical infrastructure workers” in guidance that could give the green light to exempting them from quarantine requirements.Throughout Indiana, more than 600 teacher retirements have been submitted since July, according to state data. Although the state gets most of its teacher retirements during the summer, surveys suggest more retirements than usual could happen as the calendar year progresses, said Trish Whitcomb, executive director of the Indiana Retired Teachers Association.“I’ve gotten more (teachers) calling me back saying, ‘Well, I’m going to go ahead and retire,’” Whitcomb said. “Some still wanted to go back in the classroom, but they didn’t think the risk was worth it. They looked at their grandkids and the life they have, and I think they’re saying, ‘I’m just not going to do it.’”In Salt Lake County, Utah, the state’s most populated metropolitan area, more than 80 teachers have either resigned or retired early because of concerns about COVID-19 in schools. More than half of those happened in one of the county’s five school districts, Granite School District. All of the district’s teachers who left were fined ,000 for failing to give 30 days’ notice.Mike McDonough, president of the Granite Education Association teachers union, said the departures stem from frustration over how the schools have reopened. In Granite, most students will return to in-person instruction for four days a week, and there are few opportunities for teachers to instruct solely online.Some teachers waited until the last minute, hoping that the district would change its reopening plan. But checking out of the classroom was “the only way to keep themselves safe,” he said.“Teachers are still scared and overwhelmed,” McDonough said. “I have heard from teachers that are just heartbroken to leave the classroom, but they didn’t feel safe going back. They don’t want that level of risk, and they have no other choice but to get out.”Education leaders in states including Arizona, Kansas, New Hampshire, Pennsylvania and Texas have said they are bracing for worsening teacher shortages as the pandemic drives away some educators.To try to maintain staffing levels in classrooms, the Missouri Board of Education made it easier to become a substitute teacher under an emergency rule. Instead of the previous requirement — 60 hours of college credit — eligible substitutes now only need to obtain a high school diploma, complete a 20-hour online training course and pass a background check.Iowa responded similarly, relaxing coursework requirements and the minimum working age for newly hired substitutes.In Connecticut, college students have been asked to step in as substitutes. Michele Femc-Bagwell, director of the teacher education program at the University of Connecticut, said the school has been getting requests to use fifth-year graduate students as substitute teachers. Heavy class loads and internship responsibilities, though, limit their availability to one day a week.Many who work as substitutes are retired teachers such as 67-year-old Margaret Henderson, of Phoenix, who said she will not return as she had planned.“I don’t want to get called into a classroom where a teacher has called out because of the virus or to quarantine. ... And we know that’s going to happen more and more,” Henderson said. “There are still uncertainties about the safety of reopening the school buildings. Can you blame (substitutes) for not wanting to go in?”In rural Iowa’s Hinton Community Schools, Hinton High School Principal Phil Goetstouwers said the school is already down to a third of the substitute teachers it had last year. More than half of those are also willing to sub in other districts, he said, making it even more troublesome when teachers are absent.Allen Little, who retired as a math teacher in Sioux City, Iowa, this past spring, said the “complexities” of teaching during the pandemic made him decide to retire three years earlier than he had planned. Although he anticipated returning to work as a part-time substitute this fall, fears about the virus are holding him back. He encouraged his son, who is studying to be a social studies teacher and who considered getting experience as a substitute, to weigh the risks carefully.“We’re thinking about students, our schools, our community with every decision we make,” Little said. “But we also have to think about ourselves and our families. What’s best for us, maybe more and more of us ... is not being inside the classrooms right now.”___Associated Press Writer Pat Eaton-Robb contributed to this report from Hartford, Connecticut.___Casey Smith is a corps member for the Associated Press/Report for America Statehouse News Initiative.

While Tuesday's election wasn't quite the "Blue Wave" that Democrats had hoped for, the Democratic Party won a majority of seats in the U.S. House once the new Congress is seated in January. Democrats needed to turn over at least 23 Republican seats for a total of 218 and the party claimed 222 on Tuesday night, according to numbers from CNN.Although Democrats will lose seats in the Senate, taking the House gives Democrats the ability to conduct investigations, which could pose issues for President Donald Trump pending the result of Special Counsel Robert Mueller's investigation. Ushering in a crop of new Democrats into the House, Alexandria Ocasio-Cortez, 29, will become the youngest woman in history to be elected to Congress. She upset New York Democratic Rep. Joe Crowley in the primary election earlier this year. Michigan Democrat Rashida Tlaib and Ilhan Omar, the Minnesota Democratic-Farmer-Labor Party's nominee, were elected on Tuesday as the first Muslim women in the House. Former Tennessee Titans linebacker Colin Allred, a Democrat in Dallas, defeated incumbent Pete Sessions to win his first time as a candidate.  1184
