The nurse is storing vaccines for future use. What should the nurse do so they are properly stored? Select all that apply.

A: Not all vaccines are refrigerated; some vaccines will be inactivated by refrigeration and freezing. B: Periodic checking for expiration dates is necessary to ensure that outdated vaccines are not administered. C: Not all bulk supplies should be placed in a freezer; some vaccines are inactivated by freezing. D: When refrigeration is required, a main shelf inside the refrigerator is best because a shelf in the door will have frequent temperature changes that will alter the potency of the vaccine. E: Storing food and beverage in the same unit may result in frequent opening of the unit, leading to greater chance of temperature instability and light exposure. Contamination may also result. F: Aluminum foil or packaging can be used to protect light-sensitive vaccines.
