SAN DIEGO (KGTV) — Longtime San Diego State football coach Rocky Long is stepping down after nine seasons.San Diego State officials announced Wednesday that Long will be replaced by Aztecs defensive line coach Brady Hoke.Hoke was SDSU's head coach in 2009 and 2010 before leaving to become head coach at Michigan. Long served as defensive coordinator under Hoke and replaced him when he left in 2010.RELATED: San Diego State basketball reaches top ten in polls for first time since 2014During his nine seasons as head coach, Long lead the team to a 81-38 record, three Mountain West Conference championships, and four 10-win seasons since 2015. Combined with previous head coach positions, he is 146-107 in his career."It's time. It's time," Long said. "I love coaching but I don't necessarily love all the things head coaches do."Long said it's time for a "new face" and "new voice.""It doesn't mean the message will be different it just means it will be presented in a different way ... as you grow older you know when it's time," Long said.RELATED: San Diego State's stadium effort gets -million donationLong never saw a losing season at the helm in San Diego, his team's best performances coming in 2015 and 2016 with back-to-back 11-3 records. He was named Mountain West Conference coach of the year in 2012 and 2015 and led SDSU to a bowl appearance all nine years, with four bowl wins.SDSU's most recent season saw the team end with a 10-3 record and dominant 48-11 win over Central Michigan University in the New Mexico Bowl.Since taking over as head coach, Long has led San Diego to rank 11th in rush defense and interceptions, 14th in total defense, 20th in scoring defense, 22nd in turnovers caused, and 26h in defensive pass efficiency, according to the school.It's unclear what Long intends to do next, but sources tell ESPN he spoke with Syracuse about a defensive coordinator position recently and intends to keep working. To that point, Long remained coy on those rumors, saying only that he's been contacted by programs and "as of this moment I'm retired. That doesn't mean I'm not going to listen to what they have to say.""I was smart enough to listen. And a couple of those places I visited," Long said. "I mentioned it before, I'm tired of being head coach but I love coaching."RELATED: Holiday Bowl kicks off amid uncertain futureHoke posted a 13-12 record during his first two seasons with San Diego, going 4-8 in his first year and turning the program around to a 9-4 record and Poinsettia Bowl win the next season. As head coach at Ball State, SDSU, Michigan, and Tennessee, he's recorded an overall record of 78-72. "When Brady decided to come back I told everybody he's the best defensive line coach around," Long said of his replacement. "He's a great guy and a great head coach."Hoke thanked Long and the program officials that looked to bring him back into the Aztec fold."It's great to be back," Hoke told reporters Wednesday. "You never get to do something twice that you really want to do in life ... I can assure you, we are going to keep going in the direction that we're going."Hoke said he'll next be looking at how he'll put together his coaching staff, saying "I think the guys here are a privilege to work with and are good men."In his time away from San Diego State, Hoke says he plans to continue the trends and successes already in place."I think philosophically, that hasn't changed much," Hoke said. "You always grow, if not, you won't get to where you want to go." 3521

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) — 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
