People over 65 who contract the flu are more likely to have serious complications like pneumonia. Many Americans die each year from pneumonia and other health problems caused by the flu. Flu shots are safe and effective. You can't get the flu from the flu shot. Medicare pays for the flu shot and its administration at 100 percent of the Medicare allowance.
Influenza is just another name for the flu.
Many coughs, colds and upset stomachs are commonly called the flu. But, the flu itself is an infection caused by a special kind of virus. With the flu, you usually get sick suddenly and have a fever, dry cough, sore throat and body aches. While flu shots don't prevent every little cough and cold, they can keep you from getting the flu. If you've had a flu shot and still happen to catch the flu, chances are you won't get as sick.
