CHICAGO -- Right now, nine COVID-19 vaccines are in or near a large-scale human trial phase. But enrollment of minorities in the trials remains a challenge. This is despite a disproportionate number of African-Americans impacted by the coronavirus.Earlier this month, ads from the National Institutes of Health began airing asking Black people and Latinos to volunteer for the coronavirus vaccine trials.“Operation Warp Speed” may be moving quickly, but pharmaceutical companies are having a difficult time getting Black and brown participants.“What we really bring to the table is moral persuasion and encouraging our population to participate in safe and ethical clinical trials,” said Reverend Anthony Evans, the president of the National Black Church Initiative. Over the past 15 years, they’ve worked with the pharmaceutical industry to boost Black representation in more than a dozen previous clinical trials.“I think that we can be a major help to both the government and the pharmaceutical industry if they use us,” said Evans.The Black community has been hesitant to take part in medical research and clinical trials because of a history of past abuse.Most infamously, the 40-year Tuskegee Syphilis Experiment that used Black men to study what happened when the disease went untreated.“They were just basically experimented on without their knowing about it or their understanding what was happening. And a lot of people had very bad outcomes because of this,” said Dr. Emily Landon, an infectious disease specialist at University of Chicago Medicine.A recent Pew study found that Black Americans are still more skeptical of experimental treatments and a potential COVID-19 vaccine than Hispanic and white adults.Add to that, most of the current trials are recruiting mainly online, something experts say often results in mostly white people enrolling.“We will know more and be able to do a better job in caring for our friends and patients of color if we have more participation in these trials,” said Landon.Moderna had to delay trials because of a lack of diversity. As of earlier this week, 13% of Moderna’s enrollment volunteers were Black and 51% white. At the same time, only 8% of Pfizers volunteers are Black and 75% white.“They are going to have a significant shortfall of data when it comes down to African Americans and other groups, especially Latinos, and simply because they have not made the efforts,” said Evans.In the end, the vaccine must be at least 50% effective to receive FDA approval. Without a diverse group of volunteers, experts say it could be difficult to know just how safe and effective the vaccine actually is across races. 2672

CARLSBAD, Calif. (KGTV) - Each Monday, a group of dedicated seniors gather in their woodshop, on a mission to make the holidays a little brighter for North County kids in need. The woodworking elves of the La Costa Glen senior living community in Carlsbad have spent nearly a year creating 100 handmade toys of all shapes and sizes.The toys have up to 39 pieces, crafted with various types of wood like walnut, cherry, and mahogany. RELATED: 10 special holiday events coming to San DiegoFive woodworkers spent the year making around 4,000 parts for the toys."It's all handmade, and a lot of love and care goes into putting it together," said Tom Woodbury, a member of the toymaking team. Countless hours have gone into the effort. Among the toys are a truck, grasshopper, and mouse. "There's a lot of detail in it, lot of small parts, lot of medium-sized parts, not too many big parts," said Woodbury.RELATED: Skate away on one of San Diego's outdoor ice rinks this holiday seasonToymaker Carolyn Rowland says she enjoys being part of the team."I feel very blessed, and I'm thankful for being able to live here. And one way to show that thanks is to give back to the community," said Rowland. This year, the toys will be donated to charities, including the Casa De Amparo in North County.The team also sells toys year-round to help cover supply costs, to learn more contact La Costa Glen in Carlsbad. 1408

CARLSBAD, Calif. (KGTV) - A drone company based in Carlsbad has found a way to use their drones to help the fight against COVID-19.Charles Moss, the owner of FD1 Drone, created new software that uses artificial intelligence to track the size of crowds, as well as the distance between people. He hopes it can be used to enforce social distancing in public places."It's a tool," says Moss. "It's the ultimate tool to enhance our current abilities."The software connects a drone's camera with a computer, feeding real-time information about crowd size and social distancing. It can also detect which people are wearing masks, and which people aren't.On the computer screen, green dots show people who are property distanced. Red dots mean they're too close.Moss says it can be used at parks, beaches, schools, shopping centers, concerts or anywhere else people gather.And the software isn't confined to drones. Moss says it can be installed on street light cameras, similar to the technology the City of San Diego uses in their Internet of Things system. Like the IOT system, Moss' software does not use any facial recognition technology."In order to give people a better comfort out in public, they need insight as to their environments," he says. "The human brain can only process so much data, so much information. This will help them make better decisions."Moss says he's been in contact with a few cities and schools to deploy the technology, but concerns over cost and training has kept his software grounded.He's hopeful it will catch on soon, so it can help keep people safe during the Pandemic.But he says it also has practical applications after the Pandemic ends. Moss says his software could be used to spot wildfires, measure deterioration in coral reefs, inspect power lines and more."It's more of a tool to provide situational awareness, so we can plan," says Moss. "We call it AI for good." 1914

  

Car buyers these days love SUVs. They don't, however, love actual cars like hatchbacks and sedans --as Ford has learned.Ford said on Wednesday the only passenger car models it plans to keep on the market in North America will be the Mustang and the upcoming Ford Focus Active, a crossover-like hatchback that's slated to debut in 2019.That means the Fiesta, Taurus, Fusion and the regular Focus will disappear in the United States and Canada.Ford will, however, continue to offer its full gamut of trucks, SUVs and crossovers.By 2020, "almost 90 percent of the Ford portfolio in North America will be trucks, utilities and commercial vehicles," the press release says. "The company is also exploring new 'white space' vehicle silhouettes that combine the best attributes of cars and utilities, such as higher ride height, space and versatility."By "white space," the company is referring to vehicles that don't fall neatly into the typical categories.Ford has hinted it might decide to retire much of its sedan portfolio. Earlier this year, James Farley, the company's president of global markets, said Ford is "shifting from cars to utilities," which have been a bigger profit driver. It also reallocated billion of research funds from cars to SUVs and trucks.And it's not just Ford. Fiat Chrysler did away with the Dodge Dart and Chrysler 200 more than a year ago. And General Motors decided to scale back production of the Chevy Cruze, Chevy Impala, Buick LaCrosse and the Cadillac ATS and CTS.  1514

  

CARLSBAD (KGTV)-- Four years after the devastating wildfires in San Diego County, plants have grown back and neighbors rebuilt and recovered.The 2014 wildfires raged through neighborhoods, up over hills, turning at a moment's notice fueled by the Santa Ana winds. "It looked like a war zone of black smoke everywhere all over the place of all the roads blocked off," Homeowner Bob Payne said.He was at his relative's home when he got the call, and rushed back Carlsbad to see what he could do. He said he was lucky to have been out of town, otherwise he said he would've been on his driveway fighting the flames with a garden hose.His home was one of 65 structures that burned. Firefighters fought as 14 separate fires grew, eventually?covering 26,000 acres.At Bob's home, all that was left was a safe, full of photos of smiling children and their wedding memories. It took two and a half long years, to rebuild. He didn't want to leave their prime hilltop location, close to the beach and to town."It looks different, we changed our house some. We kept the same floor plan but we put in a couple perks in there which is nice," Bob said they had a pool put in and some exterior and interior designer changes.Nearby SDG&E did an update of their own, switching out wood poles for more durable metal ones."It burned up here and the and the fire department said it was 65-foot flames that came up and went to the attic of the house and burned it down," Bob said, explaining the fire flew up one of the poles and arched down to the roof of his home.Bob said he would never forget the generosity of the neighbors and complete strangers who gave everything from clothes, to food, to necessities to help his family through the disaster."I wish everybody a happy's Mother's Day on this day and count your blessings, and just enjoy your family and enjoy your health and everything that you have," saying he's thankful for the things that can't be touched by flames. 1992
