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)- As elections are quickly approaching, a San Diego man is expressing concerns after discovering what appeared to be undelivered mail ballots and voter guides in City Heights.“I was out walking the dogs, and I found this stack of voter ballots; it was mixed in with ballot envelopes and voter guides,” said Jeremy Alaynick. “Just kept finding them the more I walked.”He sent ABC10News pictures that appeared to show a combination of approximately two dozen unvoted ballots and sample ballot/voter information pamphlets.Alaynick, a professional dog walker, said he did not report the incident immediately because he was walking dogs for a client.“I would have picked them all up and taken them to the post office, but I’m thinking about the dogs, and that just wasn’t running through my mind at that moment,” he said.He was working to report the incident Wednesday.Registrar of Voters, Michael Vu, tells ABC 10News, situations like this are uncommon, and investigations are launched as soon as his office is aware.“What we generally do is we touch base with the US Postal Service. It would have been great to receive this information at the time rather than a week later, particularly for those respective voters but also for us to be able to manage it,” he said.Vu said if voters have concerns or haven’t received their ballots by mail, options are available.“We are tracking every single one of these ballots, so when a voter says they have not received their mail ballot, we have the ability to suspend that ballot and reissue them another one,” he said. “If there are voted mail ballots that come back to our office, we compare the signature off of the envelope against the signature on file. So every single one of these is validated.”If you are voting by mail, Vu recommends tracking your ballot here.“Voters themselves, they have the ability to track their mail ballot as it’s traveling to them or traveling back to us after they voted,” he said.If you across a situation like this, Vu said to report it to his office right away.A spokesperson for the United States Postal Inspection Service tells ABC 10News they cannot comment on this matter. 2174

SAN DIEGO (KGTV) -  A world-famous artist known for his marine life artwork and conservation stopped by his own gallery in Seaport Village Tuesday.Wyland spoke with 10News about his connection to Southern California and the lives he's changing through his artwork.Peggy Williams was visiting San Diego from Idaho this week. She said she bought her first Wyland about 30 years ago."His drawings and his work of the marine life is so real," Williams said. "It's kinda cool to pop in here today and run into him. How neat is that?"RELATED: Wonderspaces 360: An extraordinary art experienceWyland said his art reflects calls for environmental consciousness."It really reflects what people are thinking about. Hey, maybe we need to protect our ocean, our environment," Wyland said.He's painted 100 ocean murals, including one still in downtown San Diego."I was inspired by Jaques Cousteau. He was like my hero," Wyland said. "I think I'm a better sculptor than painter."But he's also working on a theme called "Starry Seas," which he brought to life in front of our 10News cameras."I thought, what if Vincent van Gogh, what if he painted underwater?" Wyland said as he plopped paint directly from the tube to the canvas. "It just gives it a really organic, really nice impressionist type feel."He said his childhood helped shaped his attitude toward conservation."It was the first Earth Day. Of course, Green Peace was coming along," Wyland recalled. "When I came to California and I saw the Pacific Ocean and I saw a grey whale on that I day, I knew that was my place, that was my role."To educate and inspire the next generation of artists, Wyland is leading a national challenge."We're doing a national Wyland art challenge. It's free to every school, every student," the artist said. "With all the crazy stuff going on in the world, we need more heart and more art and I'm going to always brings that."Wyland's galleries will celebrate their 40th anniversary next year. His next big project will be 100 monuments in 100 cities - and he said San Diego is high on that list. 2124
