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) - Immigration rights advocates in San Diego are worried about the impact of President Trump's promised mass deportation. In a pair of tweets Monday night, President Trump said that U.S. Immigration and Customs Enforcement would next week "begin the process of removing the millions of illegal aliens who have illicitly found their way into the United States."Benjamin Prado is the program coordinator for the U.S. Mexico Border Program with the American Friends Service Committee. Prado says the tweets are causing concern and confusion.“We’re not sure because of the tweets, they are just so random, and very limited in scope and depth," said Prado. ICE agents carried out an immigration crack down at the Zion Supermarket in Clairemont Mesa back in February. Twenty-six workers were detained. "Our communities have experienced all kinds of things, whether it be on transportation, roving patrols, that border patrol has done in the past,”said Prado. He said his members started watching their communities long before the president's latest tweet. "Our community members are mobilizing, have been mobilizing even before this tweet, and have been out in the community, making sure Immigration and Customs Enforcement doesn’t go and separate families," said Prado. Immigration attorney Edward Orendain said the enforcement action would likely target people who have skipped out on their hearings or who have been given final deportation orders. "Apparently, this is going to be targeted more toward people who already have outstanding deportation orders or orders of deportation. Initially, that may seem to be a good thing, but I know, because I have several clients, that a significant number of the people who already have final orders of deportation are under supervised release, which means local immigration already knows of them, but they’re allowed to stay in the United States usually for humanitarian purposes," said Orendain. Orendain says he has one client, who was given final deportation orders, but is on supervised release because she has an ill son who is a U.S. citizen. "She's been removed a couple of times, but she has a U.S citizen child who has severe medical and developmental issues and really can’t get the standard of care in his home country,so the government knows about her, knows that she has final orders of removal or deportation, but allows her to stay here as a humanitarian issue," said Orendain. It's estimated more than 200,000 undocumented workers are in San Diego County. Orendain said he hopes the president's tweet has more to do with politics than any actual plan. "Maybe it was a way to stoke the fires in his base, but because of the office that he holds, it has to be given attention." 2758

SAN DIEGO (KGTV) — Millions of Americans are uninsured during the coronavirus pandemic, with more at risk of losing their jobs and in turn losing their healthcare coverage.A 17-year-old boy in Lancaster was reportedly denied treatment at an urgent care clinic there and instead told to go to a hospital. On the way to the hospital, he went into cardiac arrest, according to Mayor R. Rex Parris in a video posted to YouTube.RELATED: Reports of alleged child abuse drop in San Diego since school closuresParris said when the teen got to the hospital he was revived, but died hours later.The teen tested positive for COVID-19, but the Centers for Disease Control and Prevention is still evaluating his case, so he has been removed from the Los Angeles County death toll for now."Once you go into respiratory issues, you have trouble breathing, you're short of breath and you have a fever," said Parris. "That is the time to get medical treatment without delay."RELATED: App helps users locate where essential items are in stockThat is the problem for the millions of uninsured Americans. Although testing for COVID-19 may be free, treatment is not.10News asked health officials at a San Diego County press conference about what's being done to reassure uninsured San Diegans that they won't be turned away like the 17-year-old in Lancaster."In general if individuals do not have insurance, there is the county's phone number, or they can call 211. That's probably the easiest thing to do, is call 211," said San Diego County Public Health Officer Dr. Wilma Wooten.RELATED: Unemployment benefits could take weeksWe asked if someone would be turned away if they tried to get help at an urgent care clinic with COVID-19 symptoms, but did not have insurance."When somebody presents to a specific facility for care and it's not emergent there is usually a process for them to determine whether that is an appropriate place for them to be cared for," explained Dr. Eric McDonald, the Medical Director for the County Epidemiology and Immunization Branch. "For example if it's an insurance related thing and they don't have insurance for that facility, they may be asked to go to another facility, the good news is in San Diego we have a very good mechanism through 211 for individuals who don't have insurance to be able to access clinics where they will be accepted for care."RELATED: California Gov.

SAN DIEGO (KGTV) — If Pfizer's coronavirus vaccine is approved this week, UC San Diego Health anticipates receiving its first allocation of the vaccine next week.The vaccine will be considered on Thursday by the Food and Drug Administration. Once it receives the vaccine, UC San Diego Health says its first vaccinations could occur shortly after."Assuming the U.S. Food and Drug Administration issues an Emergency Use Authorization tomorrow or Friday, we would anticipate arrival of the first allocation of the Pfizer vaccine to UC San Diego Health next week, with the first vaccinations occurring shortly thereafter," a statement from the hospital system said. RELATED: What phased vaccine distribution will look like in San Diego CountyThe hospital system says the process of receiving and distributing the vaccine remains fluid and details still need to be finalized.Who will receive the vaccine first will be based on the CDC's Advisory Committee on Immunization Practices, which recommends health care workers receive the vaccination first, along with residents and workers of nursing homes and long-term care facilities.RELATED: What the FDA's review reveals about Pfizer's COVID-19 vaccinePrioritization of who in those first groups receives a vaccination first will also depend on doses available. But those health care workers who face the greatest exposure to COVID-19 patients will be prioritized.This week, an outside group of vaccine experts will advise the FDA and vote on whether to recommend an emergency use authorization for the drug.FDA scientists independently confirmed Pfizer’s claim that its vaccine is 95% effective after two doses and said they found no serious safety concerns, according to documents released Tuesday.Upon approval, California is set to receive 327,000 doses of the vaccine in the first round of allocation. Of those San Diego County is scheduled to receive 28,275 doses. The second round of vaccine allocation is expected within 3-4 weeks. 1991
