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

This includes funding to fix about 390 miles of streets.Parks & Rec: Mission Bay Park, Chollas Lake, Hickman Field Athletic Area, and Skyline Hills Community Park will see .5 million in park upgrades, including new lighting, trail realignments, and ADA improvements.Water system: Faulconer's proposal also includes .6 million for stormwater upgrades to channels, pumps, storm drain pipes, and watersheds.Faulconer's entire proposed budget can be viewed on the city's website. 2230

SAN DIEGO (KGTV) — It looks like just another small apartment. Living room. Bedroom. Kitchen.But the apartment complex 10News toured is unlike any other. It's a solution for homelessness."People go into treatment, they get out, they relapse and the go back in and they get stuck in this thing we call the churn of in and out, and in and out of services."So Chris and Tammy Megison came up with a solution: Solutions for Change. The idea is to get families with children off the streets and into a program that would change their lives forever."We get them jobs right away, put them to work so they can learn the soft skills of working," Chris Megison said. "They're up at 5:30. Kids are fed and off to school. And now they're going to classes, they're going to work."Solutions for change works because of its motto, driven by accountability. It's a 1000 day program. Every client must have a job, and most work in the solutions aguaponic farm. They grow their own organic food, and what they don't eat they sell, and the proceeds go back into the program. "They're not looking to be a band-aid fix, they're looking to be a 'hand up' organization. They're not lowering the bar for people who find themselves in a pretty dark tragic place, they're trying to raise the bar and set people up for future success," San Diego County Supervisor Kristin Gaspar said.And since 1999, Solutions for Change has helped 900 families escape homelessness. People like Melissa Martinez and her children who not long ago were separated without a place to call home."It's put us all back under one roof. It's actually be a lot easier than I could have ever imagined, getting everybody to and from school, to and from work, we're really united and working as a team. So it's really just brought us tremendously closer," Martinez says."All we ask is, 'Would you grab one bootstrap and let us grab the other and let's do this thing called life,'" Megison says.To learn how to help Solutions for Change or donate, visit their website here. 2024
