Dating of multidose vials
On April 10, 2015, the Provincial Infectious Diseases Advisory Committee on Infection Prevention and Control (PIDAC-IPC) updated the guidance on the use of multidose vials in Infection Prevention and Control for Clinical Office Practice.
CDC also recommends that you store food and beverages in a separate storage unit from vaccines, which you are technically doing but there may still be an impact on the refrigerator temperature by the opening and closing of the freezer door by staff.
(In most two-compartment units, cold air from the freezer is circulated for cooling the refrigerator.)The ideal situation would be to get a stand-alone pharmaceutical/purpose-built refrigerator unit for your vaccines, and use your refrigerator/freezer combination unit for your food and drinks.
Please refer to page 8 of the "Vaccine Storage and Handling Toolkit" available at https://gov/vaccines/hcp/admin/storage/toolkit/
Combination refrigerator/freezer units are less capable of simultaneously maintaining proper storage temperatures in both compartments.
If a combination refrigerator/freezer must be used, only refrigerated vaccines should be stored in the unit, and a separate stand-alone freezer should be used for frozen vaccines.

In general, the unit must be large enough to store the year's largest vaccine inventory without crowding and to store water bottles (in a refrigerator) and frozen coolant packs (in a freezer) to stabilize the temperatures and minimize fluctuations.
