SAN DIEGO (KGTV) -- We’ve known for a while that COVID-19 hits people over 65 especially hard, but a study published Wednesday from researchers in San Diego offers new insight into why that happens.The numbers are staggering: if you’re 65 or older, your risk of winding up in the hospital from COVID-19 is five to 11 times higher than someone under 30. Your risk of death is at least 90 times higher, according to data from the Centers for Disease Control and Prevention.Researchers at the La Jolla Institute for Immunology say the reason why older people fare so much worse appears to be from a lack of T-cells, a type of white blood cell that can decline with age.“Some viruses get controlled by one part of the immune system. Some viruses get controlled by another. In this case it seems that T-cells really do a lot of the work,” said Dr. Shane Crotty, one of the authors of the study published Wednesday in the journal Cell.Dr. Crotty and his colleagues looked at 50 people infected with the virus, and they measured the three elements of the adaptive immune system in detail: antibodies, helper T-cells and killer T-cells.Then they compared the measurements to how people fared against the virus. Some patients in the study group had severe cases, others had mild infections.The researchers found that people with all three branches of the adaptive immune system tended to fully recover. People with severe cases of the virus often lacked one or more of the immune branches, and it was particularly evident in older people.“Our data indicated that of the older individuals, it was particularly the ones that had fewer T-cells to start that look like they really struggled to control this virus,” Dr. Crotty said.As we age, we have fewer T-cells to send after invading pathogens. “That collection of T-cells gets smaller. So it’s harder to recognize a new virus,” Crotty said.Among the 748 deaths in San Diego County reported as of Wednesday, 87% were people aged 60 and older.The findings from LJI may have implications in the search for a vaccine against COVID-19. The data suggests that vaccine-makers may want to target a drug that elicits all three branches of the immune response, Dr. Crotty said. Some vaccine approaches, such as inactivated virus vaccines, only elicit two of three branches, not killer T-cells. However, Crotty said it was too soon to rule any candidates. Two strong branches produced by a vaccine could potentially cover for the lack of a third, he said.Crotty said the findings could help vaccine-makers interpret results from the clinical trials and find the right dosing.“Is a given vaccine a good vaccine, and you just need a booster immunization?” he said. “Does it work well in one population but it doesn’t help in the elderly because it doesn’t generate a T-cell response, for example? Those are the scenarios when this type of knowledge will come into play.” 2906

SAN DIEGO (KGTV)- After a rise in COVID- 19 cases, the governor closed many indoor activities, including places of worship. Churches around the county were forced to make changes to their services, but some embrace the new scenery.Sunday morning mass was held outdoors for parishioners at Saint Agnes Catholic Church. Members brought their beach chairs to worship in the church’s parking lot.“I love being able to see people here, gathered together, and worship together,” says Father Bill Marquis.The changes came after the governor’s announcement to stop indoor activities due to the rise in COVID-19 cases across the state. San Diego county is one a few dozen on the state’s watchlist.Saint Agnes Catholic Church says it is still offering virtual services, but it was the members who requested to have the “beach chair mass” on Sunday morning.“Parishioners asked me if we were going to have mass on Sunday, I said we were going to live stream it,” says Father Marquis. “She says we would still like to have an outdoor mass on Sunday, if possible. I said why, and she said because we want to receive communion. That was the deciding factor for me.”As many churches around the county make changes to their services, some places of worship are working with city leaders to hold outdoor services. Poway officials approved a plan to share park space with places of worship and fitness centers. The City of El Cajon is looking into a similar idea. 1452

SAN DIEGO (KGTV) -- With just weeks to go before the first day of school, parents across California are trying to figure out the best way to ensure their kids get a quality education.For some families, that means pulling their kids from a traditional district school."We're going to be homeschooling them," said parent Sarah Farsian.The Farsians have two kids, a first- and second-grader."In the pandemic, we are really afraid of sending them back to a campus," Farsian said. "Even though they're disinfected, what if they get sick."Her family is not the only one across the state making the same decision. Along with setting up their home school, some families are looking into micro-schooling or a small school. It could have regular classroom space or operate out of someone's home, using remote curriculums."First, it's going to be just us, but we are a member of a Facebook co-op group that also has accredited tutors, accredited teachers all different grades," Farsian said.Parents' decisions on where and how to educate their children could have impacts on the schools they leave."The overwhelming majority of the money to the overwhelming majority of districts from the LCFF, Local Control Funding Formula, which comes from the state, the dollars come from the state and go to the school districts based on the number of students they've got and also the distribution, the demographics of those students," said Bob Blattner with Blattner and Associates, an education lobbying and consulting firm.In a May revision to the governor's budget, the Local Control Funding Formula took a significant hit. The proposal states, "Absent additional federal funds, the COVID-19 Recession requires a 10 percent (.5 billion) reduction to LCFF."Lawmakers pushed back and passed a budget that kept school funding at current levels. Schools will get the same amount of state funding as they did this past school year. However, billions of dollars will be deferred, and schools won't be able to get it until the next school year."If we don't get federal dollars, the final budget deal starts borrowing from the next year," Blattner said."Districts are either going to have to go into their savings, and many have enough, or they're going to have to borrow. If they can't do either, the budget does have a provision giving support for districts that can't access the borrowing tools they need."Deferrals will impact districts and public charter schools a bit differently."Everybody is going to be subject to deferrals, and what that means basically is you will be reimbursed at a later date," said Myrna Castrejón, president and CEO of the California Charter Schools Association.Castrejón said in the last recession when they saw a lot of deferrals impacting the charter school sector, many of their school networks had to file for bankruptcy or borrow at commercial interest rates."Charter schools can't levy taxes, they can't pass bonds," Castrejón said."It's creating a particularly precarious perfect storm of fiscal challenge for charter schools when you can't get reimbursed for the students that are coming. You have limited access to borrowing capital to withstand the impact of deferrals," she said.Castrejón said there is a concern for some school entities when it comes to average daily attendance.The budget made it so growing schools and schools that have seen enrollment drop still get funded at the same level."Which means that for our charter schools that are growing and for district schools also that are experiencing enrollment growth, which is about 30 percent of districts across California, we're not going to be reimbursed for those students that we're serving," she explained.Castrejón said the governor did ask lawmakers to pursue solutions to fix the issue.As for Sarah Farsian, she said her kids will go back to a physical school location when they think it's safe."This is only for right now," she said. "If they can get this under control, yes (they will go back). They need to be with their friends." 4029
