PHILADELPHIA (KYW Newsradio) — We always talk about the importance of getting flu shots, and there is good reason for it. 

A CDC study looking at a six-year period has found that approximately 13 million illnesses and over 110,000 hospitalizations may have been averted by the flu vaccine being given in the United States. 

Scientists are able to measure the impact quite reliably. 

The CDC researchers regularly use surveillance data and look at vaccination coverage, vaccine efficacy and disease occurrence. 

Studies designed to assess illness and hospitalizations prevented by the vaccine are extremely important because each year, there is a need to market to the public the importance of getting flu shots.
