Here we highlight a few common misconceptions that we hope will make you better informed this flu season.
36,000 Americans die of flu-related illnesses during a typical flu season
CLOSER LOOK: It is very hard to know how many people die from any given disease because there is often much uncertainty in determining the cause of death. This is particularly true for the flu. That's because it shares symptoms with so many other diseases, and because people most likely to die a flu-related death are also at high risk for many other causes of death.

Those most at risk are people age 50 years and older
CLOSER LOOK: Ninety percent of what are labeled flu-related deaths occur among people age 65 years and older. For people younger than 65 (including children), the chance of a flu-related death is much smaller - about 1 in 100,000.
The flu vaccine will prevent me from getting sick
CLOSER LOOK: Getting the vaccine does not guarantee you will not get sick from the flu or die from it. Despite a dramatic increase in vaccination among the elderly, deaths from the flu and pneumonia have hardly budged. Read More: How Well Does the Vaccine Work?
As more people get vaccinated, the flu-related death rate declines
CLOSER LOOK: Despite a dramatic increase in vaccination among the elderly, deaths from the flu and pneumonia have hardly budged.
