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

Dozens of common breakfast cereals and snack bars have trace amounts of a controversial herbicide found in the weed killer Roundup, according to a report released today by an environmental advocacy group.The Environmental Working Group (EWG) found that 26 of the 28 products it tested had levels of Roundup's main ingredient, glyphosate, that were "higher than what EWG scientists consider protective of children's health." An earlier report found similar results in over thirty oat-based foods.List: The name-brand breakfast cereals and snack bars that contain weed killer chemicalManufacturers say their products are safe, but the EWG report argues that the vast majority of foods tested -- such as Honey Nut Cheerios and Quaker Simply Granola Oats -- have glyphosate levels that might pose a cancer risk with long-term consumption.None of the foods violated EPA limits on the herbicide, but the EWG uses a far more conservative health benchmark. California's proposed glyphosate limit, which would be the most restrictive in the country, still allows for glyphosate levels that are over a hundred times higher than the EWG's threshold.The environmental group says its lower threshold includes an added buffer for children, as "exposure during early life can have more significant effects on development later in life," according to Dr. Alexis Temkin, the lead scientist on EWG report.But manufacturers dispute that threshold. Quaker said in a statement that the "EWG report artificially creates a 'safe level' for glyphosate that is detached from those that have been established by responsible regulatory bodies in an effort to grab headlines." 1656

Devastating wildfires across the Western United States has sent smoke traveling across the country and even into Europe. With that smoke comes bad air quality, not just for those near the fires, but for the entire continent.Satelite images from NASA shows smoke thousands of miles from the fire. NASA says the smoke contains aerosols, a combination of particles which carry harmful things into the air and into your lungs. All the things that are burning, trees, grass, brush, homes, are turned into soot and absorbed by our lungs.“This pollution, nobody knows how badly it will be affected but if we extrapolate from previous air quality it's not good,” Dr. Malik Baz, the medical director at the Baz Allergy and Sius Center, said. “The long-term side effect, we’ll see many, many years down the line.”Baz’s operates 13 locations in California, all of them are busy as Central California is essentially a big bowl surrounded by mountains which trap pollution over the valley. Air quality is always an issue for this part of the state and fires multiply the problem.“People with respiratory, allergy, asthma, ,sinus problem, anytime the air quality goes bad, their symptoms get worse,” Baz said. “It affects them but this air quality, it doesn’t matter whether you have respiratory problems or not, everyone is affected.”It's bad in other western cities too."This is really an unprecedented wildfire season in 2020,” said Jon Klassen, director of air quality science and planning for San Joaquin Valley Air Pollution Control District. “We have fires across most of the states in the western US, Washington, Oregon, California, Seattle. Portland has some of the worst air quality in the world right now, which is shocking because normally they have pretty good air quality."Klassen’s job is to monitor and improve air quality and help reduce emissions.“Those sorts of emissions can come off of wildfires or different industrial sources, the burning of different material, and the challenge and the health challenge is that because it’s so small, it can get into your lungs, your bloodstream, cause damage to internal organs,” Klassen said.A good air quality index score is anywhere from 0 to 50. Some of the cities next to the fires are seeing numbers in the 400s or 500s. California, Klassen says, has had fires burn 3.4 million acres. That's larger than the state of Connecticut as a whole. And that smoke from the western United States isn't just staying local.“Just the enormous amount of emissions that are going into the atmosphere can get caught up in transport flow from the Pacific over to the Atlantic,” Klassen said. “It can slowly cross the content and into different parts of the country, which is what we’re observing right now.”Which means use the "see and smell" rule, and watch the air quality index wherever you are.Sometimes that air can make you feel bad, and doctors advise you watch your symptoms.“[Symptoms include] lethargy, coughing, wheezing, difficulty breathing, irritation of the eyeballs, sneezing, itching, nasal congestion, headaches,” Baz said. These are also the symptoms of COVID-19, which makes some problems hard to diagnose.If your air quality isn't good, Baz suggests staying in, avoiding strenuous exercise outside, changing the filters in your home and car and keeping up on your medications and hydration.And while fires aren't forever, we are unfortunately just starting a season that's shaping up to be unprecedented.“The concern here is we are in the middle of wildfire season,” Baz said. “The past few years, the season has ended in November and we’re in September, so we’ll have a couple months left to go with these fires.” 3678
