WILMINGTON, Del. – During a year-end address, President-elect Joe Biden warned that country is far from emerging from the coronavirus crisis.“Our darkest days in this battle against COVID are ahead of us, not behind us. So, we need to prepare ourselves and steel our spines,” said Biden in Wilmington on Tuesday. “As frustrating as it is to hear, it’s going to take patience and persistence and determination to beat this virus. There will be no time to waste in taking the steps we need to turn this crisis around.”Watch Biden's speech below:During his speech, Biden spoke about the 0 billion COVID-19 relief bill that Congress approved Monday and is awaiting President Donald Trump’s signature. He said the bill is a good next step, but more funding will be needed in the coming year.“I have said all along, this bill is just a first step — a down payment — on addressing the crisis we’re in. We have a lot more work to do,” said Biden.Biden also took the chance to express sympathy for the many American families who are struggling financially and emotionally as they celebrate the holidays in isolation amid the global pandemic.“With over 320,000 lives lost to this virus, Jill and I send our prayers to all of you facing this dark winter with an empty seat at the dinner table where your loved one used to sit, talk, and laugh,” said Biden. “Our hearts go out to all of you who have fallen on hard times through no fault of your own, unable to sleep at night, weighed down with the worry of what tomorrow will bring for you and for your family.”Like for Thanksgiving, the Centers for Disease Control and Prevention (CDC) is encouraging people to celebrate the end of year holidays at home with the people you live with. Gatherings with family and friends who do not live with you can increase the chances of getting or spreading COVID-19 or the flu.“Like we did over Thanksgiving, we all have to care enough for each other that we have to stay apart just a little longer,” said Biden. “I know it’s hard, but we have a long way to go.”Biden also encouraged Americans to continue taking the necessary precautions to prevent the spread of the coronavirus as the nation ramps up its vaccination efforts.“We need everyone to mask up, stay socially distant, and avoid large gatherings,” said Biden. “And we need to work in a bipartisan way. That’s the only way we’ll get through this.”Biden himself received his initial dose of Pfizer’s COVID-19 vaccine on Monday, shortly after his wife did as well. He joined a growing list of officials who have publicly been vaccinated to show confidence in the vaccination process.During his remarks, Biden said he has “absolute confidence in the vaccine,” but the country is short on supply. He explained that vaccinating millions of people will be a logistical challenge.“Taking the vaccine from a vial and into the arms of millions of Americans will be the biggest operational challenge we’ve ever faced. It will take many more months for that to happen,” said Biden. “In the meantime, the pandemic rages on.”Early next year, Biden said he will put his plans for what’s to come before the Congress. He said we will need more help to fully distribute the vaccine, to reopen our schools, to help our front-line workers, and to make sure those struggling to make ends meet are taken care of.On his day in office, Biden says he will enact masking requirements, a new strategy on testing, and work on accelerated production of protective gear.Biden also discussed the recent cyber security breach against U.S. companies and federal agencies. He blamed the Trump administration for failing to prioritize cyber security“From eliminating and/or downgrading cyber coordinators at both the White House and the State Department, to firing his Director of the Cybersecurity and Infrastructure Security Agency, to President Trump’s irrational downplaying of the seriousness of this attack,” said Biden. “In an age when so much of our lives are conducted online, cyber attacks must be treated as a serious threat by our leadership at the highest levels.”Biden said he believes we must treat cyber threats with the same seriousness of purpose that we treated the threat of other unconventional weapons.“We must work with our allies to establish clear international rules and mechanisms to enforce them and consequences for those that violate them,” said Biden.After his remarks, Biden took questions.When asked about the potential for more direct payments, Biden said his plan will include a new round of stimulus checks for the American people, but the amount is a “negotiating issue.”Regarding his choice for attorney general, he said he’s still trying to determine who will serve in that role and that “there’s not an obvious choice in mind.”When asked if he would announce his 2024 bid early to show he's not going to be a lame duck president, Biden said, "I'm not going to be a lame duck. Just watch me. Just watch me." 4960

With emotions still raw days after a deadly school shooting in Florida, one Ohio family is fighting back against what they think is an unfair punishment.Beth Mertel says one of her son's peers brought a toy gun to Greenbriar Middle School in Parma on Feb. 8, and pointed it at her son, Joey."He says he doesn't want to be the snitch," Mertel said. "They're 11 years old. They're kids. They're trying to find their place with their friends too."Mertel says the Parma City School District suspended the student who brought the toy gun, along with three other students, including Joey, for knowing about it but not telling an adult about it.The district stands behind the discipline, saying the three additional students were punished under a part of the Student Handbook labeled "Withholding Information."Mertel's concern is with the severity of the punishment, not the rule she admits her son should have followed."No matter how much I disagree with the suspension, you still should have said something," said Beth.Mertel says Wednesday's tragedy in Florida is an important teaching moment."I said [to Joey] you need to go home and turn on the news," said Beth. "You need to watch this, you need to understand this."The district tells us that suspension will stay on Joey's internal school record through middle school and into high school. Beth says it's a hefty punishment that falls short of teaching the lesson she says is worth learning."Whenever you see something, you have to tell somebody," said Mertel. "That's the only way this is going to be taken care of." 1605

When you go out to eat or visit the grocery store, you’ll probably spot an employee wiping down tables or spraying carts with disinfectant. These sanitizers can kill the novel coronavirus, but doctors warn some can also cause chemical burns and allergic reactions on your skin.“Depending on the strength of these disinfectants, they can cause damage to the skin. They can react like a burn would, which can appear with significant redness or swelling to the skin,” said Dr. Frederick Davis, who works in the emergency department at the Long Island Jewish Medical Center.One Florida family believes their baby got a chemical burn after sitting in a Walmart cart sprayed with disinfectant.Davis said alcohol, bleach and ammonia, often used in commercial sanitizers, can create that reaction.“A lot of these cases, unfortunately, happen because people think it’s a disinfectant, it kills bacteria and viruses, it’s safe to apply to the skin, but it definitely isn’t,” he said.Environmental Biology Professor at the University of Arizona Dr. Charles Gerba said commercial disinfectant can be harmful to skin until it dries completely.“You don’t want to put the child down in the seat if it’s wet with disinfectant,” warned Gerba.Parents should dry carts or any surface covered in disinfectant before letting kids touch them, but experts caution, disinfectants may not work properly if they cannot dry on their own.So, to keep your kids safe and kill the germs, Dr. Gerba recommends placing a towel down in the cart or using a baby wipe to remove harsh chemicals that can build up over time.“That’s one of my concerns,” said Gerba. “You keep adding these chemical disinfectants on every single day, they’re subject to misuse, like not drying enough, so you might get some exposure,” he said.Because of these dangers, Dr. Gerba is experimenting with a replacement for commercial grade sanitizers with a company called Allied Bioscience. It’s a spray coating that sticks to any surface, even touch screens, and kills bacteria and viruses for months at a time.“It’s the same principle as odor eater socks,” said Gerba. “The reason the socks didn’t smell is it killed the bacteria that caused the odors,” he explained.Michael Ruley is the CEO of Allied Bioscience and said he hopes this coating will make its way onto airplanes, into schools and grocery stores soon. “With this coating going down, it gets ahead of the threat and is proactive instead of reactive,” Ruley said.This new technology is still getting approved by the EPA, but studies show it can fight the coronavirus.“They killed the coronavirus pretty well, like 99 percent or more, within a few minutes sometimes,” Gerba said.This product needs to be applied once every 90 days to remain effective, which would lift much of the workload off employees to clean places.“That’s the whole goal is to get people back feeling comfortable in the environment and be able to go out and enjoy their environment,” said Ruley.But until the frequent sanitizing ends, Dr. Gerba warns just because a surface is clean, doesn’t mean it’s safe for you or your kids to touch. He said the best way to protect your skin is to immediately wash your hands after touching anything that’s been sanitized. 3243

  

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.
