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 battle over the Crossroads of the West Gun Show continued Tuesday in Del Mar.The Board that oversees the fairgrounds is reviewing the show that has been hosted at the fairgrounds for the last 28 years.A pro-gun, second-amendment political action committee collected more than 3,100 letters in support of continuing the show in Del Mar.The letters were given to the board for review and consideration. Michael Schwartz, Executive Director of the San Diego County Gun Owners is pushing is pushing for the board to renew the shows contract with no restrictions or limitations."It took us less than a week to collect all these signatures, we could have gotten more. Some are written by entire families who come to the show every year. It is a family event with almost a 30 year history with Del Mar," said Schwartz. Protesters also made an appearance at the board meeting dressed in orange and asking the board to cancel the shows current contract.The Del Mar, Solanna Beach and Encinitas city councils have approved resolutions calling for a ban on the gun shows at the fairgrounds.Guns can be purchased at the show, but California law requires extensive background checks and a waiting period.The board will make a decision to cancel or continue the gun show at it's board meeting in September. 1329

SAN DIEGO (KGTV) -- The message from nurses and caregivers Tuesday morning was clear, "it's a question of priorities for entire healthcare system." Frustration and anger built after a 27-month contract renewal was signed by Palomar Health's CEO, Diane Hansen. The contract details a base salary close to million, with potential of earning bonuses, increasing that amount. Frontline workers argue that because COVID-19 led to an increase of patients, and layoffs of caregivers and nurses, "the board should have invested in resources and more protective equipment. Some of the PPE is not even medical grade, and everyone who's been laid off should be brought back," said representative for California's nurses association, Sarah Gurling. Gurling joined other reps and nurses in a protest at Palomar Medical Center, arguing funds should have been allocated towards other resources within their facilities."Caregivers and nurses are the heart of the hospital. We know what's best for patients and each other. The hospital executives and the Palomar board has lost sight of that." Meahwhile, Palomar's health board chair, Richard Engel, stands behind his decision. He said Hansen has done a tremendous job and credits much of the hospital's success through her work. Engel added her salary is comparable to other hospital's CEO's.Registered nurse, Sue Phillips, said their efforts will continue no matter what. "We want the community to know we're here, we're going to keep fighting for them." 1501
