More than 40 percent of a sample of U.S. adults believes the myth that flu vaccines can give you the flu, and even correcting that misconception might not convince them to get the vaccine, a new survey suggests. “It is absolutely biologically impossible to get the flu from the vaccine,” said Dr. Gregory A. Poland, a professor of medicine at the Mayo Clinic in Rochester, Minnesota, who studies the immunogenetics of vaccine response. He was not involved with the new study. It seems logical that dispelling this myth would lead to more people getting the shot, but it may not work that way in real life, Poland told Reuters Health by phone. “Things that seem logical and intuitive can have perverse effects that we don’t always understand or expect,” he said. The new results show that teaching patients about the safety and efficacy of the vaccine shouldn’t be ‘one size fits all,’ he said. “I think we have to move toward a model where I as a physician have to change my style of educating based on my listening and understanding what your educational needs are,” he said.
