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 Emmy Awards will be held live, and socially distanced, Sunday night to celebrate excellence in the television industry. It will be the first big Hollywood event broadcasted live amid the pandemic.Jimmy Kimmel will host from the Staples Center in Los Angeles. Other celebrities taking part include Morgan Freeman, Lin-Manuel Miranda, D-Nice, Patrick Stewart, Jason Bateman, Laverne Cox, Abbi Jacobson, RuPaul and Oprah Winfrey.Rather than using taped segments or elements like other awards shows this year, the Emmys will be using 130 cameras in 20 cities in ten countries to achieve a live show.Some of the nominees will be participating from home, surrounded by friends and family.Show producers are not expecting things to go smoothly, telling CNN Kimmel will be available throughout the night to “jump in as soon as anything goes wrong," producer Reginald Hudlin said.And what will Kimmel do? “If something happens technically, I will be touching upon all the skills I’ve acquired over the course of my life. I know one magic trick. I can kind of juggle. I guess I could draw caricatures of the crew,” Kimmel told The Hollywood Reporter.The 72nd Emmy Awards will air Sunday at 8 p.m. ET on ABC. 1209

The Detroit Lions will play Tampa Bay without interim coach Darrell Bevell, making him the NFL’s first head coach to miss a game because of COVID-19 protocols.Detroit’s coaching staff will also be without defensive coordinator Cory Undlin, defensive line coach Bo Davis, defensive backs coach Steve Gregory, and linebackers coach Ty McKenzie in Week 16.Wide receivers coach Robert Prince will be the team’s third head coach this season on Saturday at Ford Field against the Buccaneers.Bevell was 1-2 after Matt Patricia was fired last month. Quarterbacks coach Sean Ryan will call plays in place of Bevell, who also serves as the team’s offensive coordinator, against the Bucs. Evan Rothstein, who helps the team with research and analysis, will lead the defensive staff.Bevell said Wednesday he had not tested positive for COVID-19, but he was one of the coaches affected by contact tracing. The Lions closed their training facility on Tuesday because one player and one coach tested positive for the coronavirus, and resumed on-field preparations on Wednesday to face Tampa Bay. 1088

The CEOs for auto giants Kia and Hyundai have refused to attend a congressional hearing to explain why hundreds of their vehicles have spontaneously burst into flames.Both carmakers and a spokesman for Democrats on the Senate Committee on Commerce, Science and Transportation have confirmed the companies’ refusal to send representatives to the hearing, which has been scheduled for next week.A Kia spokesman said the company is working with the committee to “analyze all relevant information associated with any fire or other safety-related matters and will take any necessary corrective action in a timely manner.”A Hyundai spokesman said, “Hyundai takes this matter very seriously, and fully appreciates the concerns of the Senate Commerce, Science & Transportation Committee including those of the Chairman and Ranking Member.”It was not immediately clear whether the U.S. Senate committee would postpone or cancel its Nov. 14 hearing on Kia and Hyundai fires.The call for the hearing came six months after Consumer Investigator Jackie Callaway, of WFTS television station in Tampa, Florida, first reported on the unexplained car fires.Since April, the WFTS I-team has exposed hundreds of Kia and Hyundai models manufactured since 2011 that caught fire across the country.“The hearing will focus on motor vehicle safety issues involving vehicle fires,” stated the identical letters – dated Oct. 16 – and sent to Kia Motors America President and CEO Seungkyu “Sean” Yoon and Hyundai Motor America's Kyung Soo “Kenny” Lee.The CEOs were asked to “promptly identify and respond to defects that may pose a fire risk” at the Nov. 14 hearing in front of the Senate Committee on Commerce, Science and Transportation.In September, an Ohio mother spoke out and called for a federal investigation after watching her son burn alive in her 2014 Kia Soul parked at her apartment complex just outside of Cincinnati last year. 1926

The excitement of two COVID-19 vaccines with more than 90 percent efficacy is undeniable.In November, both Pfizer and Moderna announced its scientists had developed vaccines with efficacy at or near 95 percent, but scientists are warning these vaccines are not the "silver bullet" to ending the pandemic.“We don’t want to give the public the impression that there’s an emergency use authorization and these vaccines become available in a small amount in December and we can go back to our pre-pandemic behavior,” said William Moss, executive director of the International Vaccine Access Center at Johns Hopkins.In June, the FDA released its vaccine guidelines, saying it would consider emergency use authorization for any vaccine testing with at least 50 percent effectiveness, so there is a reason for celebration, according to Moss, but only after certain questions about the vaccine are answered.Dr. Anthony Fauci has said the initial vaccines will prevent symptoms in those who become infected, rather than kill the virus itself. Moss says that means immunized people might be able to spread COVID-19 to others.He also wonders how long immunization will last. One year? Three years? Will booster doses be needed? They're all careful considerations that will only emerge once one is put into play, according to Moss.“It’s obviously tragic that the [COVID] cases are occurring that quickly, but it does help a vaccine trial because otherwise you just have to wait that much longer for samples to come in,” said Moss.The vaccine process has innovated how scientists and researchers approach these types of situations, however, according to Moss.In traditional vaccines, a small dose of the virus is injected into the body so the immune system can create antibodies. In the COVID-19 vaccine, though, both Moderna and Pfizer have used what is called messenger RNA (mRNA) where the virus’ genetic code is injected into the body so it can instruct cells on what antibodies to produce. Scientists say this way is faster, safer, and can create a stronger immune response as people are not exposed to the virus.“I suspect that if this all goes well and these vaccines are safe and continue to demonstrate 90 to 95 percent efficacy, we’re going to see other vaccines of a similar type,” said Moss. 2298
