GOODFELLOW AIR FORCE BASE, Texas -- Chief Master Sgt. Robert Puhl, 17th Training Group chief enlisted manager, receives the FluMist from Tech Sgt. Nicole Melius, 17th Medical Group, Sept. 29, 2009. The FluMist is a live, but weakened, influenza virus that is sprayed into the nostrils as opposed to the flu shot, a dead virus, that is injected into the muscle. (U.S. Air Force photo/Staff Sgt.
