Nearly half of Americans think flu shot can make you sick

More than 40 percent of a sample of U.S. adults believe 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.
