Why this answer
35 to 46 °F (2 to 8 °C) is the refrigerated storage range in the joint-service immunization regulation. The question puts the vaccine in a working refrigerator, so the refrigerated range is the one that applies, and the same paragraph says it must not be allowed to freeze. The 5 °F line is for vaccines that are stored frozen.
