Dating of multidose vials
The toolkit was extensively revised in 2019 to provide more concise and updated information. Dormitory-style (bar-style) units pose a significant risk of freezing vaccine even when used only for temporary storage.During testing, dormitory-style refrigerators demonstrated consistently unacceptable performance, regardless of where the vaccine was placed inside the unit.The use of multidose vials for injectable medications and vaccines increases the risk of transmission of blood-borne pathogens and bacterial contamination of the vial and should be avoided.Patient safety should be prioritized over cost when choosing between multidose and single-use medication 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.This guidance was revised as a result of inquiries from health care providers from outpatient and inpatient settings to clarify when opened multidose vials should be discarded.(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.
Always store them below vaccines and on a different shelf.Inactivated vaccines must be kept between 2 and 8C (between 36 and 46F) and not frozen.Generally speaking, CDC recommends avoiding the top shelf and the areas near vents due to temperature fluctuations.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.
