SAN DIEGO (KGTV) — In the race for a coronavirus vaccine, scientists often say we need more than one winner.That’s in part because different vaccines use different strategies to provoke the immune system, and each strategy has different strengths.Take the inactivated virus vaccine, an approach currently used in the vaccine against the poliovirus. In this approach, scientists take a live virus, kill it with chemicals or heat, and then introduce that viral corpse into a person.There are three groups in the final phase of human trials using inactivated coronavirus, primarily in China, according to a tracker from the Milken Institute.“The immune system can tell the difference between something that's a real threat and something that's not a threat, and so if you get injected with a dead virus your immune system has the tendency to not pay a lot of attention to that,” said Dr. Shane Crotty of the La Jolla Institute for Immunology.The downside of the inactivated virus approach is that it only elicits two out of the three of the parts of the immune system, Dr. Crotty said. It’s capable of producing antibodies and helper T-cells, but not killer T-cells.The modern take on the inactivated virus approach is called a viral vector vaccine.In this strategy, scientists combine elements of the coronavirus with a common cold virus called an adenovirus that won’t make you sick. Since the virus is alive, it can elicit all three kinds of immune responses, Dr. Crotty said.“There are no licensed vaccines right now that use that strategy, but there are all kinds of vaccine trials that have been done around the world with those types [of vaccines] showing that they're straightforward to manufacture. They're very safe,” he said.The University of Oxford is testing a viral vector vaccine for COVID-19 in a Phase 3 clinical trial.Then there are subunit vaccines. These include just a section -- or subunit -- of the virus’ protein.UC San Diego is working on a coronavirus candidate vaccine using this approach.There are subunit vaccines currently on the market for tetanus and other viruses.“Working with proteins is more challenging, just from a laboratory and manufacturing perspective,” Dr. Crotty said.Enter the next phase of vaccine development. Instead of using the virus itself or fragments of it, Inovio Pharmaceuticals is working on a vaccine strategy using just the virus’ genetic information.DNA-based vaccines simply introduce a genetically engineered blueprint of the virus into a person, and the cells do the rest.“Some people get confused about this. They think it’s a genetic vaccine that changes their DNA and becomes part of them, and that’s definitely not the case.” Dr. Crotty said. “They don’t become part of you. Your body chews them up.”Researchers have been working on DNA-based vaccines for about 20 years, Crotty said, but none are currently licensed for use.San Diego-based Arcturus Therapeutics is using an RNA-based approach, along with other companies like Pfizer and Moderna that have entered Phase 3 trials.Messenger RNA reads the DNA instructions and helps translate them into proteins.Dr. Crotty said the DNA and RNA approaches have similar drawbacks and benefits: they’ve never been approved for us, but both can be developed rapidly because they don’t require access to the physical virus.Around the world, there are more than 200 coronavirus vaccines currently in development, according to the Milken Institute. 3459

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) -- Many Black female voters in San Diego voters are celebrating Joe Biden’s decision to choose California Sen. Kamala Harris as his running mate.“This is a historic moment. I’m excited that I’m alive to see this happen,” said Ellen Nash, the chair of the San Diego chapter of the Black American Political Association of California.“All along that was the right choice,” Nash told ABC 10News. “I’m honored that she’s there to represent Black women and the Black vote. For Joe Biden to honor us by selecting her as his VP is the greatest historic moment.”Many Black voters wrote to Biden, urging him to choose Harris.Nash said having Harris as the first Black and Asian American woman to appear on a major party’s presidential ticket gives women of color a voice.“It was just a moment of relaxation and celebration,” said Nash. “She is prepared, skilled, and credentialed.”But does this choice possible boost Biden’s chances of winning this election? Dr. Kyra Greene, the executive director at the Center on Policy Initiatives, said Harris would bring new life to this race while appealing to a wide range of voters.“She’s young enough to attract young folks but old enough to show experience and to be taken seriously,” said Greene. “I think it will help with women who were disappointed not to see other women advance further in this race, and I also think it will help with Black voters.”“I think Senator Harris speaks to people who are interested in change because she herself has gone through an evolution on these issues,” she said.Greene said the decision not only makes history but will reenergize some of the most politically engaged San Diegans. 1678

SAN DIEGO (KGTV) — It's been 25 years since President Bill Clinton approved Operation Gatekeeper, the measure focused on the issue of immigrants crossing the border illegally — specifically the San Diego sector.Two key parts of Operation Gatekeeper were surveillance equipment and enforcement infrastructure, like walls and fences. Twenty-five years later, Border Patrol Agent Theron Francisco tells 10News, "Before Gatekeeper this area was in utter chaos, agents were apprehending 1,000 per shift. We had hundred of thousands of apprehensions a year." It's a measure that Francisco says paved the way for Border Patrol today."It's absolutely night and day from where we were back then," Francisco said.Tuesday, those against Operation Gatekeeper held a rally. Former Border Patrol agent Jenn Budd tells 10News, "That was the whole purpose, to push them out here to make it more difficult and dangerous for them to cross. I didn't want to be a part of it but its something I have to admit I was a part of."Budd tells 10News, it's partly why she left Border Patrol, "I left because I felt the policies we were enacting were killing people and what we were representing to the public wasn't the truth." Meantime, Border Patrol agents say it's only helped increase San Diego safety."The days are gone where illegal aliens are running through people's backyards trying to hide from Border Patrol," Francisco added. Budd says, "We need them to work for us, we need them to protect our borders we need them to keep drug smugglers out, but we don't need children dying in their custody and all sorts of things they're doing right now." 1637
