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) - Local activists spoke out in Escondido Wednesday denouncing a recent ICE sweep in San Diego County that resulted in the arrest of 115 people. While agents say the raids targeted convicted criminals and people who'd been previously deported or ordered deported, those holding the protest say the tactics used are unfair and unnecessary.They urged the immigrant community to know their rights and reach out for help from experienced immigration attorneys.  496

SAN DIEGO (KGTV) — Low-lying parts of San Diego are dealing with the possibility of more coastal flooding Saturday and Sunday morning because of "King Tides." The high tide event is expected to occur the mornings of December 22 and 23, according to tidal charts. King tides occur when there is an alignment of the gravitational pull of the sun and the moon. RELATED: Sandbags available in San Diego CountySome parts of Imperial Beach already experienced tidal flooding Friday morning as several homeowners reported water entered their homes. Wow! Really high tide here in Imperial beach. Water soaking the area. @10News pic.twitter.com/F3P6dNr7HS— Mimi Elkalla (@10NewsMimi) December 21, 2018 700

SAN DIEGO (KGTV) - In just a few weeks, voters will decide the fate of the San Diego Chargers' former home, now known as SDCCU Stadium.In a recent 10News/Union-Tribune poll, Measure G, known as SDSU West, is the clear front-runner.With the clock winding down, backers of both Soccer City and SDSU West are blanketing the airwaves in hopes of winning over voters.10News analyzed two advertisements currently airing on our station and put their messages to the test, separating fact from fiction.The first ad we looked at deals with Measure E, better known as Soccer City. The ad features soccer star Landon Donovan asking two people if they want to see the future. After showing one of them a video of the design planned for the location, one of the people asks Donovan how much it will cost for what he saw. Donovan says, "It won't cost you a dime."10News analyzed that statement and found it to be in a grey area.According to a San Diego City Attorney analysis, a private developer would normally pay the city for staff time spent processing its development. It’s unclear whether any city staff time will be reimbursed.Also, the City Attorney analysis noted the initiative does not establish the actual amount of rent the city would be paid for a 99-year lease of the property.The ad goes on to claim taxpayers get the same stadium that's currently there for the next ten years and it's going to cost six million dollars a year. Team 10 can’t verify timing but according to the City Attorney analysis, Measure G provides for the sale of approximately 132 acres.The measure doesn't talk about time frames and does not guarantee that the property would be sold or that any specific development would be built.Team 10 also read through the City of San Diego Office of the Independent Budget about stadium costs. The report says the stadium historically operated at a deficit.Officials with Soccer City disagreed with some points of our analysis saying the initiative pays fair market value. They also pointed to provisions in the ballot language saying it shows city costs will be covered.Team 10 also took a look at a Measure G ad starring former San Diego Mayor Jerry Sanders.The ad starts with Sanders saying “Voters have a big decision in November. The choice is clear, SDSU West, Measure G on the ballot is a once in a lifetime chance to grow the university to meet the needs of future students.”The ad says Measure G will create a western campus for SDSU with a research center, a beautiful public park along the restored San Diego river, affordable housing and a home for SDSU football and soccer.A 10News analysis found those statements to also be in a grey area.All of that could happen, but the city attorney's analysis says voter approval of this measure does not guarantee that the property would be sold or that any specific development would be built. It goes on to say if the property is sold to SDSU, the Board of Trustees of the California State University will determine the use of the property in its sole discretion - through a Campus Master Plan revision process. A Campus Master Plan revision does not require City approval.The review also notes the initiative does not address who would plan, build and maintain the river park.An official with Measure G sent 10News a statement saying: 3334
