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

Donald Trump's personal attorney Michael Cohen also represents Fox News host Sean Hannity, Cohen's attorneys said Monday afternoon.Cohen had told the court earlier he had at least 10 clients between 2017 and 2018, including the President, and the former GOP fundraiser Elliot Broidy who acknowledged paying .6 million to a Playboy model with whom he had an affair.Judge Kimba Wood ordered Cohen to attend and provide information about his clients as she weighs an emergency action by Cohen's attorneys to stop prosecutors from reviewing more than a dozen electronic devices and documents seized during a FBI raid of Cohen's office, home and hotel room last week. 672

Donald Trump Jr. has been temporarily suspended from certain functions on Twitter for violating the website's rules for spreading misinformation regarding the COVID-19 pandemic.According to a screenshot of Trump Jr.'s account shared by Republican strategist Andrew Surabian, Twitter suspended the president's son over a tweet that included a video with dubious COVID-19 information.On Monday, Trump Jr. tweeted a video of a group of people who claimed to be doctors who were touting the effectiveness of hydroxychloroquine, a drug which the president has said is an effective treatment for COVID-19. The video also discouraged the use of masks.Several studies have shown the drug has not been effective in treating the virus, and in June, the FDA removed an Emergency Use Authorization for the drug in connection with COVID-19 treatments.CNN reports that the video was originally published by Breitbart News. Facebook and YouTube reportedly removed the video from their platforms Monday as the video began to go viral.According to Surabian's screenshot, the Trump Jr. has been barred from tweeting, retweeting, "liking" tweets or following other accounts. The president's son still has the ability to send direct messages and view his timeline. 1252

During a stop for his book tour in Missoula, Montana, Monday night, former Vice President Joe Biden discussed his 2020 prospects, saying he believes that he is the "most qualified person" to be president, noting a decision is coming in the next two months, and acknowledging he's a "gaffe machine.""I'll be as straight with you as I can. I think I'm the most qualified person in the country to be president," Biden said to applause at the University of Montana. "The issues that we face as a country today are the issues that have been in my wheelhouse, that I've worked on my whole life.""No one should run for the job unless they believe that they would be qualified doing the job. I've been doing this my whole adult life, and the issues that are the most consequential relating to the plight of the middle class and our foreign policy are things that I have -- even my critics would acknowledge, I may not be right but I know a great deal about it," he added.Biden said his family must now decide as a "unit" whether or not they're prepared for a run -- setting a decision time frame of the next six weeks to two months."I have two young grandchildren my son left who love me and adore me and want me around. I want to be there to take care of them, so we've got to figure out whether or not this is something we can all do as a family," he said. "We're going to make that decision in the next six weeks to two months, and that's the basis of the decision."The moderator, Bruce Feiler, pointed out some of the potential liabilities of a Biden campaign, saying "He's too old. He signed, he cosponsored the crime bill. He was the chairman of the judiciary committee during the Anita Hill hearings, and he's out of touch in the era of Me Too. .5 million ain't gonna cut it anymore, you need 0 million. Who wants to wake up at 6 a.m. for the next two years and get insults from the President of the United States?...You're a gaffe machine. I could go on. Which of these scares you the most?""None of them," Biden said before moving on to defend some of those potential liabilities."I am a gaffe machine, but my God what a wonderful thing compared to a guy who can't tell the truth," he said. "I'm ready to litigate all those things, the question is what kind of nation are we becoming? What are we going to do? Who are we?""Whether or not I run, whoever runs, I'm going to break my neck to make sure they win," he said. "We can't have four more years."Earlier in the night, Biden discussed some of the missteps of his 1988 presidential campaign, including accusations of plagiarism while he was in high school."It all came out in the wash -- I never did plagiarize, I never did -- and it all was proven that that never happened," Biden said.However, in 1987, Biden acknowledged that he had plagiarized part of a law school paper.The-CNN-Wire 2854
