U.S. Air Force Staff Sgt. Cherie Gregory, an allergy

U.S. Air Force Staff Sgt. Cherie Gregory, an allergy and immunization technician with the 35th Medical Operations Squadron, annotates in a patient’s medical record of their immunotherapy visit at Misawa Air Base, Japan, Jan. 14, 2016. The allergen is kept in a Styrofoam container and cooled in the immunization clinic’s refrigerator for each step of their prescribed therapy. Most vaccines are kept between 35 and 46 degrees Fahrenheit, while live vaccines, for instance the flu vaccine, must be kept frozen at 5 degrees Fahrenheit or cooler. Gregory is a Tampa Bay, Fla., native. (U.S. Air Force photo by Staff Sgt. Benjamin W. Stratton)
