SAN DIEGO (KGTV) — In their push to reopen schools, some political supporters of President Donald Trump have cited COVID-19 research from a group of San Diego scientists, claiming it’s evidence we could be close to herd immunity from the virus.But one of the authors of that research says that conclusion is way off.One of the most prominent supporters of the herd immunity conjecture is Dr. Scott Atlas, a neuroradiologist and senior fellow at Stanford University’s Hoover Institution who became an adviser to President Trump this month.“There’s a pretty good chance that herd immunity requires way less infections because of existing immunity out there,” Atlas said in a livestream conversation with San Diego County Supervisor Jim Desmond. “It actually may have already been reached in places like New York. We don’t know, but it’s possible.”Herd immunity is the level of protection needed to effectively stop the virus from circulating, thought to be about 70 percent of the population. The “existing immunity” to which Atlas is referring has to do with T cells.“It's just a misunderstanding of the science,” said Dr. Shane Crotty, a virologist at the La Jolla Institute for Immunology who co-authored the groundbreaking research on T cells in June.Crotty and his colleagues found that 50 percent of people unexposed to the novel coronavirus had T cells that could recognize it. Scientists refer to this as cross-reactive T cells, and the study was replicated in other countries.Proponents of the herd immunity theory take the number of people infected with the coronavirus, add the number of people with T cells that can recognize the virus, and come up with a number around the herd immunity threshold of 70 percent. But the math doesn’t work that way, according to Crotty, in part because T cells only kick in once a virus has hijacked cells, meaning T cells alone can't stop a pathogen in its tracks.“We’re not saying those 50 percent of people have protection like they’ve already had the virus,” Crotty said. “We’re saying those 50 percent of people have a head start in responding to the virus, which is a good thing but doesn’t affect herd immunity.”Since the novel coronavirus is a new pathogen, scientists did not expect people would have tools in their immune system capable of recognizing it. Unexposed people do not have cross-reactive antibodies, Crotty said.But in a study published this month in Science, Dr. Crotty and his colleagues offered a potential explanation for the surprising T cell results: they found these cross-reactive T cells also recognized four other coronavirus strains that cause common colds.Their theory: the T cells were created in response to other coronaviruses but can recognize SARS-CoV-2 like a distant relative.“It's a memory of a cousin,” Dr. Crotty said.That memory may speed up the body’s immune response, which can normally take about a week for an unknown pathogen, Crotty said. But scientists aren’t sure yet what role T cells actually play in clinical outcomes.“We have no data and and neither does anybody else as to whether these T cells really help or not,” Crotty said.To answer that question, scientists would need blood samples for lots of healthy people and then they would have to closely study individuals who got infected.The La Jolla Institute for Immunology is raising money for that kind of research, Crotty said, but they’re not there yet. 3417

SAN DIEGO (KGTV) — In a departure from recent years, Warner Bros. will be a no-show at San Diego Comic-Con's revered Hall H this year.A WB spokesperson confirmed to 10News that the studio and DC Comics will forgo any Hall H panel. In recent years, Warner Bros. has been pivitol for Hall H panels, especially in 2018 when Marvel and HBO elected not to take the stage.The decision was made all the more surprising — for fans, disappointing — considering the studio's upcoming slate of comic book movies, including "Joker" (Oct. 4, 2019), "Birds of Prey and the Fantabulous Emancipation of One Harley Quinn" (Feb. 7, 2020), "Wonder Woman 1984" (June 5, 2020), and "The Batman" (June 25, 2021).MORE COMIC-CON 2019 NEWSLast year, the studio used Hall H to preview "Wonder Woman 1984," "Aquaman," "Shazam!," "Fantastic Beasts: The Crimes of Grindelwald," "Godzilla: King of the Monsters," and "The Lego Movie 2: The Second Part.""Wonder Woman" director Patty Jenkins confirmed the news on Twitter this week, saying, "By now you’ve heard: WB isn’t going to Hall H this year. We’re so sad to miss you there! And waiting until Dec. to start our official #WW84 campaign in full-- But the truth is… we can just… barely… wait…" 1224

SAN DIEGO (KGTV) -- Mayor Kevin Faulconer is among local leaders expected to leave for Mexico City Sunday morning. The trip, which includes Imperial Beach Mayor Serge Dedina, is meant to strengthen ties between the border. The mayors plan to discuss border infrastructure projects, pollution in the Tijuana River Valley and economic ties with leadership in Mexico. RELATED: Trump threatens to 'close' parts of US/Mexican border if Mexico doesn't immediately halt immigrationThe trip comes as President Trump said he would shut down the border with Mexico if the country doesn’t handle the wave of asylum seekers entering the U.S. The San Diego Regional Chamber of Commerce says shutting down the border would have severe consequences. “Our daily lives are effected by the border crossings and how long that takes. So we certainly wish that not to be something to be toyed with,” said Jason Wells, Executive Director of the San Ysidro Chamber of Commerce. The San Ysidro Port of Entry is the busiest land crossing in the U.S. with nearly 100,000 vehicles and pedestrians crossing every day. 1098

SAN DIEGO (KGTV) - It’s not the new uniform that sells to thousands of adoring fans.  However, San Diego Gas & Electric’s new employee uniforms could save customers hundreds, if not thousands of dollars.All of SDG&E’s 1,800 employees that work in the field will have new uniforms by the end of the year.“The new uniforms have an embroidered logo on them. The other ones had a patch, which potentially could be removed,” said SDG&E Gas Training Supervisor Scott Hazlett.Hazlett said that embroidered logo replaces a patch worn on uniforms.  He said scammers could take the patch and put it onto any clothing. Hazlett said the embroidered logo is harder for scammers to duplicate.An SDG&E spokeswoman said someone tries to scam a customer almost every day.  The new uniforms give customers another layer of proof that they’re dealing with a legitimate SDG&E employee.Hazlett added any customer with doubts should always ask for identification and they should call SDG&E directly at 1-800-411-7343 to confirm they are dealing with an employee.The new uniforms are also lighter weight and can protect employees better from sparks and fire.“It feels great to know that the company really values its safety,” said Hazlett. 1263
