Why is it important to get a flu shot?

Flu isn't innocent: The flu shot is highly effective at preventing not only you from getting the flu, but from you spreading it about. Most who get the flu have high fevers, coughing, and vomiting and misery. A large group get pneumonia, and about 36k die in this country every year. Those with infants under 6mo have to get the shot so baby doesn't get it. Infants are especially susceptible to bad consequences.

Prevents death.: The most important point is that the flu shot prevents deaths from flu. It does not prevent to have the flu.
