Each winter, many people wonder whether its worth getting a flu shot while health officials repeatedly warn against not getting one.Now a new study sheds light on the benefit of doing so. Even when the flu shot is just 20% effective it can still reduce US doctor visits due to illness by an estimated 20 million in a single year, the new report published in the scientific journal PNAS (Proceedings of the National Academy of Sciences of the United States) finds.In addition, vaccination also can prevent thousands of hospitalizations and deaths, the study authors estimated based on the average vaccination coverage rate in the United States."Getting vaccinated against influenza is beneficial to the individual and to the community even when the vaccine is of relatively low efficacy," said Burton H. Singer, co-author of the study and an adjunct professor for the Emerging Pathogens Institute at University of Florida in Gainesville.Caused by viruses, flu is a contagious respiratory illness with mild to severe symptoms that can sometimes lead to death. The flu virus evolves rapidly and new viruses circulate in different parts of the world, so each year scientists must reformulate the vaccine. Add to that an imperfect manufacturing process and even a 'good match' formulation may not be as effective as scientists would like.In fact, the Centers for Disease Control and Prevention estimated just 36% effectiveness for the 2017-18 seasonal vaccine as of February 3. (The season ends in May.)For the new study, Singer and his colleagues created a mathematical model of flu transmission and vaccination to evaluate how much illness is prevented by even a very low effectiveness flu vaccine. The research team found that at the average rate of US coverage even a poor vaccine would prevent a significant amount of illnesses, hospitalizations and deaths.For example, at just 43% coverage (the average rate of Americans who received a flu shot for the years 2012 through 2017), a vaccine with just 20% effectiveness could avert more than 20 million infections or illnesses as compared to not getting the vaccine. In addition, 129,000 hospitalizations and 61,000 deaths could be prevented.Based on the model, if more people got a flu shot, say half of the US population, the same 20% effective flu shot would prevent an additional 3.63 million infections, 21,987 hospitalizations and 8,479 deaths."When a vaccine is fully effective on 50% or more of the people who are vaccinated, you need to primarily focus on vaccinating young children," said Singer. The reason? Children are still building immunity and they pass germs around at school."As efficacy of the vaccine decreases, it becomes increasingly important for the elderly to be vaccinated in addition to young children," said Singer, since the elderly are more likely to develop complications from the flu, such as pneumonia, which can be deadly.The CDC reported a total of 160 flu-related deaths in children and 30,064 flu-related hospitalizations overall?between October 1, 2017 and April 21, 2018. The highest rate of hospitalization occurred among adults 65 years old and older.Richard Webby, a flu scientist who is part of the World Health Organization's advisory board and a member of St. Jude Children's Research Hospital's Department of Infectious Diseases, said "effectiveness estimates go up and down based on a number of factors including match of vaccine and circulating strain and probably other factors we don't fully understand.""The take home message from the past few seasons is that there is much room for improvement," said Webby, who was not involved in the research.Still, more people, particularly the elderly, need to get vaccinated even when the vaccine effectiveness is lower than hoped, Webby said: "This study suggests that even with a less than optimal vaccine there is still much public health benefit that can be achieved if these are used properly and widely." 3992

EL CAJON, Calif. (KGTV) -- Two firefighters were injured fighting a blaze that sparked near El Cajon Wednesday afternoon according to Cal Fire. Cal Fire says the blaze started on the 5500 block of Dehesa Road around 4 p.m. and burned 25 acres. As of 6:40 p.m. Wednesday, the fire is 50 percent contained. An incident report shows that two firefighters were injured, though the extent of their injuries was unclear. The blaze did for a brief time threaten structures, but none were damaged. Due to the blaze, the San Diego County Sheriff's Department evacuated Vista De La Montana east of Dehesa Road. Evacuation warnings were also issued for Trafalgar Road, Calle De Nicole, and Vista De La Montana. The agency tweeted just before 7 p.m. that all evacuation orders and warnings had been lifted. #VistaFire [update] All evacuation warnings have been lifted for Vista De La Montana, Trasalger Rd, and Calle De Nicole. There are no more evacuation warnings or orders in place for this fire. pic.twitter.com/r1LB8UkMNI— CAL FIRE/SAN DIEGO COUNTY FIRE (@CALFIRESANDIEGO) July 18, 2019 1088

EL CAJON, Calif., (KGTV)-- San Diego Gas and Electric (SDGE) unveiled their new line of firefighting tools Wednesday afternoon, including a helicopter and a new tactical command vehicle. A little spark can transform into a violent rage. That is the fear and reality of a wildfire. "Californians were devastated and had the most destructive and deadliest wildfire season last year," SDGE Chief Operating Officer, Caroline Winn said. In 2018, there were 8,000 fires in the state that scorched more than one million acres. While no one can predict mother nature, SDGE says they are more prepared than ever. Meet Bruce Pulgencio's newest ride, the UH-60 Blackhawk. The aircraft is SDGE's newest member of their fire fighting arsenal. It can reach up to 140 mph, carry 860 gallons of water, and fills up in only 45 seconds. "It will dip the bucket into the water and pull out then we will go to the fire and be able to release the water to the fire," pilot Bruce Pulgencio said. "We just keep rotating to dip site to drop site."The copter and the pilot share a similar story. The aircraft came from the Army Surplus. Pulgencio just retired from the Army National Guard. After their military careers, the two joined together to fight fires from the sky."it's like driving a smaller sports car and then driving a semi-truck," Pulgencio said. The semi-truck he is referring to is SDGE's premiere firefighting helicopter, the Erickson Aircrane. Its 2,650-gallon tank has been assisting San Diego fire agencies for a decade."It can get into smaller places," Pulgencio said about the new Blackhawk. "We all have our specialties, where they have their snorkels, and we have our bucket. It's just a different way to approach the water and to fight the fire."Since its debut in June, the Blackhawk has already proven its value. It flew over last week's Caliente fire in Otay Mesa. Surrounded by terrain that ground crews had a difficult time accessing, the brand new UH-60 Blackhawk dropped thousands of gallons of water atop the pallet yard. Also joining the team this season is the new SDGE Tactical command vehicle. The mobile electrical hub is a place where scientists can gather and send the latest weather mapping information to ground crews on the fire line."It allows our teams to deploy quickly, and we can establish full internet and satellite phone capabilities in any location," Winn said. On the ground and in the air, the community can rest assured that their firefighting arsenal is stronger than ever. "It's another tool in our toolbox to support the firefighters," CAL FIRE San Diego Deputy Chief Nick Schuler said. 2661

EL CAJON, Calif. (KGTV) - Starting Monday morning, Cal Fire San Diego is suspending all burn permits for outdoor residential burning.The announcement comes after a dry winter and warming temperatures dried out the annual grass crop.The suspension bans residential outdoor burning of landscape debris like branches and leaves.“We are reminding the public that this last winter was drier than last year,” said Chief Tony Mecham, Cal Fire San Diego/San Diego County Fire Chief. “The abundant dry grass will only serve as a fuse to the heavier vegetation that still covers our local open spaces.”RELATED: Volcan Mountain brush fire preventing officials from reaching reported crash siteSince the beginning of January, Cal Fire has responded to 920 wildfires across the state.Mecham is also asking residents to ensure they are prepared for wildfires by maintaining a minimum of 100 feet of defensible space around homes and buildings.“The importance of defensible space cannot be over-emphasized, but just as important is that residents conduct their clearance activities in a safe and responsible manner," Mecham said. “This includes using the proper tools and limiting clearance activities to the early morning hours when the humidity is up and the temperatures are down.”RELATED: Firefighter battling Barrio Logan fire shocked by electrified fenceBelow are some tips to help prepare homes and property: 1423
