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) - Local health care workers are seeing a massive number of at-risk patients through virtual visits amid concerns over COVID-19. “We've gone from having 100 visits a day [by phone or video] to 1,200 visits just yesterday alone, says Dr. Abi Olulade with San Diego's Sharp Rees-Stealy Group. She and hundreds of doctors with Sharp Healthcare are putting a special emphasis on telehealth appointments with patients who are considered at-risk because their immune systems can be weaker. RELATED: Coronavirus Impact: Concern over nurses' protective gear“[Patients] with lung disease, heart disease, diabetes and those that are immuno-compromised so we are focused on our higher risk patients,” she tells 10News.This week, 10News interviewed Dr. David Wetherhold at Scripps Health whose team is also trying to reach that same population through Scripps' telehealth program. It was supposed to roll out over the next 18 months, but with COVID-19, it's compressed into a few weeks. “The immuno-compromised, transplant patients, heart failure patients or cancer patients. [They’re] going to be our initial focus [with] trying to get them the care they need remotely without bringing them out into the community," Wetherhold said.RELATED: In-person EDD services temporarily closed“They are more at-risk of getting severe complications from coronavirus so we want to limit them coming into the office when we can,” adds Dr. Olulade. She wants to remind at-risk patients to stay in communication with their providers about any new symptoms, even if mild, that could warrant a need for further evaluation. If an office visit is required, she tells 10News that they'll prepare accordingly to receive those patients and limit any risks they could face. 1762
