For maximum effectiveness, vaccines need to be maintained at the appropriate temperature. Most vaccines should be stored between 35 and 45 Fahrenheit. However, it is always important to double check the label because some vaccines have other temperature storage requirements.
Temperatures in refrigerators can vary, especially from top to bottom. Be careful of placing vaccines in the bottom of the refrigerator where they may have an increased chance of freezing. Freezing can be very detrimental to the effectiveness of some vaccines. When purchasing vaccines, make sure they have been handled appropriately by the local supplier or during shipment if ordered online.
