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) – Wearing masks and social distancing, churchgoers in Mira Mesa gathered outside of the Good Shepherd Parish Wednesday for a special Veterans Day mass.Under San Diego County's latest move into the purple tier, outdoor mass will be the new normal for the church until we move back into a less restrictive tier.“We want to protect the people,” said Father Michael Pham, a pastor at the Catholic church. “Health is important.”He said since reopening, the church has offered services inside at a limited capacity, outside and online. By Saturday, indoor operations will cease due to the county falling back into the purple tier.“We want to comply with the state and health department,” said Pham. “It’s a challenge, but people seem to adapt very well.”While Pham plans to comply, some others are pushing back.Skyline Church posted a lengthy statement to its website, reacting to news of the purple tier. Part of the message said, “Regardless of what tier the governor assigns to San Diego County, our Board, Trustees, and staff all agree that it is necessary to remain open for the overall health and well-being of our communities.”We saw this happen during the last round of closures. Some churches kept their doors open, saying shutting them any longer would lead to severe problems for people, including mental health issues.The county’s public health officer sent cease and desist letters to a few, but some continued to fight back, arguing that religious services are essential.“Fighting for our religious freedoms and pushing back against government overreach is not only worth the cost, it’s essential,” said the pastors of Awaken Church in a video posted to the church’s website months ago during another closure.Pham said his main goal is to protect his congregants and only reopen once allowed.“We try to do the best we can,” he said. “People are really conscientious about what they need to do, that’s important, that’s the reality that we live in right now.” 1991
