SAN DIEGO (KGTV) -- The cost of living in San Diego has become more burdensome over the last year, according to a new report from the Bureau of Labor Statistics. The bureau says that while prices fell 0.3 percent between May and July of this year, prices for consumer goods have risen 1.4 percent over the last 12 months. The cost of housing is up more than three percent since this time last year while food prices rose by a little more than one percent. Nationally, prices for consumer goods are up nearly 2 percent year-over-year. Also year-over-year, the price for fuel and utilities has risen by more than 6 percent, according to the bureau. 656

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

SAN DIEGO (KGTV) — The man accused of fatally stabbing a motorist seven times in the South Bay during a road rage dispute was convicted of second-degree murder Friday.Jurors found Rickey Vernon Smith, 60, guilty after only one day of deliberations in the Nov. 27, 2018, slaying of 36-year-old Horace Williams Jr.Smith is set to be sentenced on Dec. 11.RELATED: Local man brings families light in times of needThe road rage confrontation between Smith and Williams came to a head near Chula Vista Golf Course, after the two argued along several roadways last November. Williams reportedly threw a soda cup at Smith's vehicle before Smith struck Williams' minivan.Prosecutors say Smith then got out of his truck after cutting Williams off, walked over to his driver's side window, punched Williams in the face and walked away, until walking back and stabbing Williams several times with a knife.Witnesses said Williams got out of his van and collapsed in the roadway, bleeding heavily. The father of five was pronounced dead at Scripps Mercy Hospital in San Diego.RELATED: Father of five killed in Chula Vista road rage stabbingSmith's attorney argued Williams was the aggressor in the case. During a 911 call after the stabbing, Smith told a dispatcher Williams had cut him off and threw a drink at his truck. He added that he followed Williams and later punched and stabbed him out of self-defense after Williams punched him.Smith claimed Williams had lunged at something near the center console of his van and Smith produced his knife "as a last resort," defense attorney Brian Watkins said in court.Prosecutors argued against those claims, citing physical evidence that Smith had forcefully stabbed Williams and was not harmed in the altercation.City News Service contributed to this report. 1801

SAN DIEGO (KGTV) — The Navy has called off search and rescue efforts to find a Sailor from the USS Theodore Roosevelt who reportedly went overboard.Navy crews from the San Diego-based carrier and five other vessels ended the search at sunset on Saturday. Crews and the U.S. Coast Guard searched more than 607 square nautical miles for more than 55 hours off the coast of Southern California.Ships began rescue efforts after a lookout spotted what they believed to be a person in the water at about 7:30 a.m. on Thursday, according to the Navy.RELATED: San Diego-based USS Theodore Roosevelt searching for Sailor overboardThe Navy ad the Sailor's family identified him as 20-year-old Aviation Ordnanceman Airman Apprentice Ethan Garrett Goolsby of Texas.Goolsby reported to the USS Theodore Roosevelt in July after his initial training as an aviation ordnanceman in Pensacola, Fla. He was promoted to his current rank on Sept. 16. "The loss of our Sailor is felt deeply by all on board," said Capt. Eric Anduze, commanding officer of Theodore Roosevelt. "The entire Theodore Roosevelt team sends our deepest condolences to the family of our missing shipmate."The Sailor's family was notified before the search stopped. The Navy said it has changed the Sailor's status to "deceased."Rear Admiral Doug Verissimo, commander of Carrier Strike Group Nine, added that the strike group, "sends our thoughts and prayers to the family and loved ones of our missing shipmate. I offer my thanks to all the Sailors and Coast Guardsmen who were involved in the search."The USS Theodore Roosevelt departed San Diego several days ago for an exercise at sea ahead of its second deployment of the year, according to USNI News. The ship is set to change its homeport from San Diego to Bremerton, Wash., for an overhaul in 2021. 1816
