SAN DIEGO (KGTV) -- The Centers for Disease Control and Prevention Wednesday confirmed a second case of the novel coronavirus in San Diego County. According to CDC, the patient was aboard a flight from Wuhan, China that arrived at MCAS Miramar last week. UC San Diego Health confirmed the individual is being treated by the hospital. Their condition is unknown at this time. This is the 14th confirmed case of the virus in the U.S. RELATED: Mislabeled sample led to release of San Diego coronavirus patientRead the full statement from the hospital below: 563

SAN DIEGO (KGTV) - The California Highway Patrol said a person arrested at gunpoint on Interstate 15 in San Diego Thursday was suspected of driving illegally in the HOV lane and leading an officer on a pursuit.The chase happened on southbound I-15 just south of Aero Dr. at 5:30 p.m.Officers said the driver was in the high-occupancy vehicle lane and failed to pull over, leading to the brief pursuit.There are no reports of any injuries or a reason why the driver did not yield for the traffic stop. 508

SAN DIEGO (KGTV) -- The Navy is trying to find the owner of a boat that washed ashore at the Naval Base Coronado.The boat washed up and came to a rest against the fence that separated Coronado’s dog beach from the base.The Navy is asking the owner to come forward immediately to have the boat removed. The problem can get costly for the Navy.Several boats have already washed ashore this year. If the Navy can’t locate the owner, they have to cover the removal cost.Anyone with information on the boat’s owner is asked to call the Navy legal office at 619-545-8141. 573

SAN DIEGO (KGTV) – The Fleet Science Center is offering a program that helps San Diego students navigate their way through any challenges they face while distance learning.Participating students will have to go through a health screening before entering the building at Balboa Park.Once inside, classrooms are transformed into individual hubs. Students each have a workspace where they use their own electronic device to connect to their distance learning classrooms. Educators are there helping with any issues that may come up.Andia Pebdani, the Youth Engagement Manager for the Fleet Science Center, said the idea of the hubs came from families who needed help juggling the work life with schools being closed.“Some families don’t have the option at home, or it’s like, ‘I needed to do this so I can do my job, but I can also make sure my student is on the computer,’” said Pebdani.During breaks, educators work on different science activities with the kids or they get tours of different parts of their museum since their doors are still closed to the public.The cost for this program is 0-0 a week depending on whether you have a membership with the center. Scholarships are also available.The program’s hours are from 9 a.m.-4 p.m.To sign up or for more information go to www.fleetscience.org. 1313

SAN DIEGO (KGTV) — The back-to-back announcements of promising clinical trial results from Pfizer and Moderna may usher in a new era for vaccine technology.Both companies have candidates that rely on a new kind of vaccine strategy: RNA. Preliminary data show both candidates are more than 90 percent effective.On the surface, the vaccine candidates look like any other you’ve taken. They work by training your body to build up defensive weapons against a virus, like antibodies and T-cells.But instead of training your body by introducing a killed virus or a fragment of a virus, the vaccines from Moderna and Pfizer introduce a set of instructions called messenger RNA enclosed in a little blob of fat.“The key concept of RNA is that they’re messages, and they’re meant as short-term messages,” said Dr. Shane Crotty of the La Jolla Institute for Immunology.Crotty said there are 5,000 to 10,000 messages within a cell at any given time.Once administered, the mRNA in the vaccine instructs some of your cells to make the coronavirus’ signature spike protein. The spike protein on the surface of the coronavirus allows it to infiltrate and hijack cells.Even though the spike protein is just one of about 25 genes the virus has, preliminary results from the clinical trials suggest it is enough material to train the immune system without making the recipient sick.Crotty likened the process of training the immune system to spotting a sedan. If the coronavirus is a car, the spike protein might be the door.“There's no way that car door could turn into a whole car, but it's enough of a piece of a car for your immune system to recognize that car if it saw it again,” he said.Scientists started by sequencing the virus’ DNA from a sick patient, then encoding that genetic sequence into an mRNA instruction molecule that can be read by the manufacturing part of cells.From there, Dr. Crotty said it’s a bit like the messenger app Snapchat.The mRNA gets injected into the body, sending temporary instructions to your cells that last for a while, then disappear. mRNA does not genetically modify cells, he stressed.“They’re around as messages for some period of time and then they go away, and the cells get back to their normal job of reading their own messages instead of reading the messages you’re injecting in the vaccine,” he said.The concept has been around since the 1990s, but there are currently no RNA vaccines on the market for any pathogen, so Dr. Crotty said it’s hard to estimate how long their protective effects will last.Some vaccines offer a lifetime of protection, like the measles vaccine. Others offer decades of protection. The flu vaccine only lasts about six months.Dr. Crotty said the length of protection depends on how fast the virus mutates and how long the immune cells survive in the body.But even if the COVID-19 vaccine turns out to need an annual update, he’s optimistic. The best feature of RNA vaccines is that they can be quickly reprogrammed.Both Moderna and Pfizer are still in their Phase 3 trials, but they expect to finish them by December. Together, they estimate they’ll have enough doses for about 35 million people by the end of this year, primarily for healthcare workers and high-risk individuals. 3250
