Answer: A. On any shelf below the top shelf.
In addition, vaccines should be stored at least 2-3 inches from rear and side walls. All of a sudden, the refrigerator that looked like it had a lot of storage space when you bought it is having a hard time handling the multitude of vaccines you need. Domestic refrigerators are usually cooled with air below the freezing point blowing onto the top shelf. Not a problem for foods resistant to freezing, but a big problem for liquid vaccines whose potency can be destroyed by freezing.
The opposite problem occurs with vaccines stored in the door as the temperature goes above the recommend top temperature of 8°C as the door is opened. Biologic-grade and freezerless refrigerators have evaporator coils designed to not produce freezing conditions, making them much safer. Another advantage of biologic-grade refrigerators is the presence of internal circulation fans that keep the temperature more even throughout the refrigerator. In these fridges, all the shelves can be used and vaccines can be stored right next to walls.
2. Can you store frozen vaccines (MMR, Varivax, ProQuad, and Zostavax) in the freezer compartment of a domestic refrigerator?
A. Per recent CDC guidelines, this is now forbidden for VFC vaccines but OK for privately purchased vaccines.
B. Per recent CDC guidelines, it is forbidden for all stored vaccines.
C. Per recent CDC guidelines, it is allowed but “discouraged” for all vaccines.
