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) — It's a disease that kills nearly a half million people a year. Mostly children. But painstaking work right here in San Diego is bringing the world ever closer to ending malaria."After you've been doing it for a while you get a little bit tired," said PhD student Madeline Luth, as she works over a microscope, "You're hands get a little bit shaky."She's part of a research team at UC San Diego involved in tedious, precise work."I'm using my syringe here to separate out a single mosquito," she said, "to isolate the thorax which contains all of the malaria parasites." Malaria is a parasite spread by mosquitoes; making the insect the deadliest organism on the planet -second only to humans. Millions of people -primarily in poor parts of the world like Africa- are made sick by the parasite every year. And hundreds of thousands die."What we're trying to do is interrupt the process so the infection never takes hold in your liver.," said Dr. Elizabeth Winzeler, who heads up the research team at the UC San Diego School of Medicine. "So you never develop any symptoms of the disease".Dr. Winzeler says here team has tested more than a half million compounds against the parasite. And is now about to release hundreds of promising mixtures to researchers around the world. "They can take the recipes and the information that we've used and start their own anti-malarial drug development," says Dr. Winzeler.The open door approach with no intellectual property protections, is made possible by billions of dollars in grants from the Bill & Melinda Gates Foundation. It is also a necessity since the vast majority of those new drugs will save, are too poor to pay for medicine. The venture is purely to save lives. "We're doing this for the good of humanity, says Dr. Winzeler, "And I think everyone is on board with this idea." Even if, says PhD student Madeline Luth, some of the work is hard to explain."It's a little strange telling people I dissect mosquitoes every Wednesday morning." 2022

Most people would like to have more money, but they don’t always like talking about it. 10News is exploring solutions in our coverage of Making It in San Diego. The fear can grow when retirement comes closer. “You wake up and it’s already gone, and I’m in my early 60s and all of a sudden you have to plan for these things,” says Bob Bishop, who is close to retirement age.

You don't have to put away because you've already put away the amount you want to put away.” 1387
