Last year's seasonal flu vaccine effectiveness was just 42%, the US Centers for Disease Control and Prevention estimated. Even if vaccinated, then, people had inadequate protection against the flu.This limited effectiveness was due to a mutation that occurred in the influenza A (H3N2) vaccine strain, according to a new study published Monday in the journal Proceedings of the National Academy of Sciences. This vaccine mutation resulted from an egg-based manufacturing process commonly used today.This year's flu vaccine may also be imperfect, said Scott Hensley, author of the new study and an associate professor at the University of Pennsylvania. Add to that, he said, "this could end up being a pretty bad flu season."Still, he said, "our best protection" against severe illness is getting vaccinated with the flu shot we have today.Finding answersEach year before flu season begins, a vaccine is made based on whichever virus strains are expected to circulate. The selected seed strains are distributed to vaccine manufacturers which then produce their formulations and make them available to health care professionals before the season begins.During the 2015-16 season, vaccine effectiveness was 47%, while for the previous 2014-15 season, effectiveness was just 19%, according to the CDC. While the overall effectiveness of last season's vaccine was 42%, it was only 34% effective against the H3N2 viruses that dominated the season.Vaccine effectiveness varies based on how well it matches the circulating virus strains. Sometimes, a vaccine corresponds to the predominant virus yet its effectiveness is still not what scientists would expect. Trying to understand which element of the vaccine failed is difficult.Hensley and his team began their investigation of last year's vaccine by looking at the seed strains that had been distributed to vaccine manufacturers. These seed strains had been propagated in chicken eggs, the common method used today."The sequences of these viruses are available and when we did an alignment to see what the sequence of these vaccines were compared to the viruses that were circulating, it became very obvious that there was this mutation," said Hensley.To see the effects of the mutation, the team next looked at how the immune systems of both animals and humans who'd been inoculated with an egg-based flu vaccine responded to the actual circulating viruses.The antibodies -- immune system proteins that fight invading pathogens -- elicited in both animals and humans failed to bind to and neutralize the flu viruses, Hensley and his colleagues found.While most vaccines in the United States are made in chicken eggs, a small fraction are produced in insects or mammalian cells, Hensley explained. (These are given to people with egg allergies.) He and his team compared immune responses in animals and humans who had received a cell-based vaccine -- in this case, Flublok made by Protein Sciences Corporation."And we found both animals and humans receiving that (cell-based) vaccine had superior antibody responses that could bind and neutralize these circulating H3N2 strains," said Hensley.Making a better vaccine"Most of the infrastructure to produce vaccines in the US is based on chicken eggs," said Hensley. There are good reasons for this, including the fact that egg-based propagation allows manufacturers to quickly produce large quantities of vaccine.While egg adaptations have always been a problem, beginning last year it had become a "huge problem," said Hensley. "As soon as you try to grow this virus in eggs, within a few hours, the virus will acquire this kind of mutation."This is not an easy problem to fix, he said. To produce vaccines in cells means "a very expensive process for companies to just change their overall manufacturing process," Hensley explained. "You can't really do that on the drop of a dime."Meanwhile, the same seed strains used last year are being used this year to make the current vaccine, said Hensley."This year may be especially difficult because, in addition to this egg adaptive mutation which was present last year, there's indication that the H3N2 viruses are actually evolving," said Hensley.Not only will the vaccine be a mismatch with the actual circulating viruses due to egg adaptation but the vaccine could also be a mismatch due to unexpected viral evolution.What kind of flu season is ahead?It's too early to speculate which viruses will become dominant in the United States over the course of the coming flu season, said Hensley, "but it's starting to look like it will be H3 viruses." H3 viruses are influenza A viruses."There are the A group of viruses and the B groups," said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University. "The A groups are the ones that usually are responsible for large epidemics ... whereas the B flu strains usually smolder along. They always cause illness -- it can be just as severe as the A strains -- but they don't produce large outbreaks."Though last year's vaccine was mostly ineffective in thwarting the flu, it still prevented nearly 30% of hospitalizations that might have resulted, according to CDC calculations. For older adults, that rate was even higher, at 37%. Plus, the vaccine reduced outpatient visits by 42% last season.The CDC advises everyone 6 months and older to get a flu shot, as only injectable flu vaccines are recommended. More than 130 million doses of flu vaccine have been distributed so far this year and flu activity is still low across the nation.It's still early days, but experts believe we may be facing a tough season, and not only because of vaccine concerns.The reason?Australia had a tough flu season this year, with a total of 215,280 laboratory-confirmed cases and 504 flu-associated deaths reported to its National Notifiable Diseases Surveillance System as of October 13, government data show. According to a surveillance system report, adults over the age of 80 and children between 5 and 9 years old have been most affected."In general, we get in our season what the Southern Hemisphere got in the season immediately preceding us," Dr. Anthony Fauci, director of the United States' National Institute of Allergy and Infectious Diseases, said in an interview last month.An "intelligent guess," therefore, is that the Northern Hemisphere, like the Southern Hemisphere, will likely battle more cases of the viral infection, he said, though "with influenza, it is never 100%.""If H3N2 viruses dominate the US flu season again this year, vaccine effectiveness will likely be moderate to low again," said Hensley.Still, he said, everyone should get their annual flu shot."The other components of the vaccine, like H1N1 and influenza B, will likely provide excellent protection," said Hensley. "The vaccine will also likely prevent severe disease and death caused by H3N2 viruses, even though this component of the vaccine is mismatched."  6969

LAKE CHARLES, La. — The holiday decorations are up around Lake Charles. Yet, the most wonderful time of the year just simply isn’t right now for many there, like Renee LeBleu–Booth.For a decade, she and her husband lived in their home, which is now missing a roof and beset by toxic mold because of Hurricane Laura.“It was beautiful. I loved it,” LeBleu-Booth reminisced. “It's depressing, but we're thankful we got a roof over our head.”Their temporary new home is an RV parked on their front lawn. It’s been a tough year for them, with her husband also battling leukemia, as they tried to save money for his treatment.“We cut back on everything,” she said.That included dropping their homeowner’s insurance, a crucial decision that’s now left them with no way to pay for repairs.They’re not alone. Many are having trouble recovering from the one-two punch of Hurricanes Laura and Delta. About 46 percent of the people who live in the affected areas live paycheck to paycheck.Getting government aid can be a long process and nonprofits are trying to fill in the gaps.“We've moved into the long-term recovery phase,” said Denise Durel, with the United Way of Southwest Louisiana. “So, now, we're actually going to be putting homes back together of low-income people who don't have insurance on their homes or their property.”However, she says a more permanent recovery is going to require many helping hands.“We need to continue to let, you know, the rest of the country remember that we're here and we've got this huge challenge ahead of us still,” Durel said. “We're strong people and we take care of each other. But we just need help right now. We really just need help.”Back at Renee LeBleu-Booth’s home, this longtime United Way volunteer now finds herself getting their help.“It’s hard,” she said, adding of those at United Way, “The people were amazing.”She said they are helping her restore her faith that they’ll find a way through.“It's going to get better,” she said.Hurricanes Laura and Delta left more than billion in damages. So far, more than 236,000 insurance claims have been made in Louisiana. A federal judge recently approved a plan to deal with thousands of lawsuits expected to be filed by homeowners against insurers over disputes about damage assessments. 2291

Law enforcement arrested a man in connection with a West Palm Beach-area sledgehammer attack and theft of thousands of dollars?in February.Roady Sanozier, 38, is charged with hitting a courier, employed by Cord Financial Services, with a sledgehammer and stealing 8,000 in a heist at a business center on North Australian Avenue in Mangonia Park.On the day of the attack, the suspect fled the scene in a black Toyota Tundra. Law enforcement searched a neighborhood near the scene the day of the attack and robbery but did not arrest anyone.Sanozier, a former Cord Financial employee who was fired in August 2017 for stealing more than ,000 in cash from the company, was developed as a possible suspect in the robbery.A probable cause affidavit said that Sanozier posted a video on April 21 of himself near a black Toyota that was parked beside his car.Using that video and Google Maps, detectives traced the video to a home in Coral Springs, where they found him and took him into custody on April 25.Sanozier admitted to police that he wired ,000 cash to Haiti on Feb. 17 and bought three vehicles for a total cash value spent of ,500.A friend of Sanozier owned the Toyota Tundra, but investigators believe Sanozier was the getaway driver the day of the robbery.He faces homicide, battery, robbery and larceny charges in connection with the attack.  At a Wednesday morning court hearing, no bond was issued. If convicted, he could spend life in prison.  1564

LA JOLLA, Calif. (KGTV) - Researchers at UC San Diego have developed a new way to field test for Fentanyl, a dangerous opioid that is deadly even in trace amounts.Similar to diabetes testing strips that measure glucose levels, the scientists at the Center for Wearable Sensors created a testing strip that can detect Fentanyl."You simply swipe the surface and collect the sample and analyze it in one or two minutes, on the spot," says Joseph Wang, the Center's Director.The strip uses electrochemical carbon and silver electrodes. The meter runs currents from the electrodes through the sample. Based on how the material reacts, it can tell if Fentanyl is present, down to a nanogram level.They recently published their success in an article in the Chemical and Engineering News.The practical applications of the testing strips are wide-ranging, says Wang. He believes that law enforcement, first responders, border patrol agents and post office workers would use this new technology to test any unknown substance.Recently, law enforcement agencies have been looking for ways to field-test for Fentanyl, since any contact with the drug can lead to an overdose or even death.The San Diego Sheriff's Department bought 15 TruNarc devices this past fall. Those scan materials and tell what kind of drugs are present. But they cost nearly ,000 each.RELATED: New device keeps first responders safe from dangerous drugs at crime scenesWang says his lab's testing strips can be made for pennies, and the meters needed to analyze the sample could cost less than .Addiction advocates also believe this could save lives among drug users, by giving them an easy, cheap way to test the drugs they take and make sure they're not laced with Fentanyl. Wang says his test is simpler to use than current testing strips.RELATED: Drug users can now test if Fentanyl is in the drugs they are using before injection"This could save lives," says Wang. 1943

LA JOLLA, Calif. (KGTV) - People from all over the world come to La Jolla Cove for its beauty, its water and to get an up-close look at the seals and sea lions living on the rocks. The two eyesores they don't come to see, however, are impossible to miss. "I suddenly turned around and saw these two structures and said, 'whoa! How'd that happen?" said Rich Heleniak, who was visiting the Cove on a recent Friday. Heleniak was referring to cottages called Red Roost and Red Rest. Built in 1894, they are the oldest structures still on their original location in La Jolla. At first glance, it's easy to see they have been crumbling for decades."They've been vandalized over the years, bricks have been thrown, there was an arson fire," said Corey Levitan, a journalist for the La Jolla Light newspaper who has tracked the cottages for years. The cottages were designated historic in 1976, meaning former owner Jack Heimburge could not redevelop them into apartments. Instead, he neglected them until his death in 1998. Heimburge also owned the La Jolla Cove Hotel and Suites next door, so his motivation to ignore them was up for debate. "There was never enough money to take care of the cottages properly," Levitan said. "Then again, this guy owned the hotel, I think there was enough money to take care of the cottages properly."In his will, Heimburge split the ownership of the cottage among his heirs.A multi-year legal battle over what to do with them settled in 2018, clearing a key road block to revamping the cottages. "Take the original structure and rebuild the outside, and they've got carte blanche on the inside to do whatever they want, right?" said Catherine Oborne, a tourist who stopped to see the cottages. The parent company of Cove Properties Inc., which also owns the Cove Hotel and Suites next door, did not return messages seeking comment.The group has retained La Jolla architect Alcorn Benton to design the project. The firm declined to comment, saying the owner is currently reviewing the alternatives and that the schedule is not yet finalized. The cottages were originally called the Neptune Bungalows. A Los Angeles attorney named George Leovy designed them and used one as a vacation home in the 1890s. A banker named Joseph Fishburn owned the other. 2287
