Requirements necessary to ensure proper vaccine storage:
Appropriate refrigerators and freezers must be used. Dormitory style refrigerators are not acceptable.
Vaccines must be stored at the appropriate temperatures.
Vaccines intended for refrigeration are to be stored between 35 and 46 degrees Fahrenheit (2–8 degrees Celsius). Temperatures outside this range can destroy the potency of vaccines, rendering them ineffective.
- Zoster (shingles) vaccine and all varicella-containing vaccines must be stored frozen. Potency of varicella-containing vaccines is particularly temperature sensitive and these vaccines must be maintained at or below 5 degrees Fahrenheit (-15 degrees Celsius).
- Measles-mumps-rubella, human papillomavirus, rotavirus, varicella, and certain influenza vaccines must be protected from light at all times, since such exposure may inactivate the vaccine viruses.
Temperatures must be monitored and recorded daily.
- Accurate thermometers should be placed next to the vaccines in the middle of the freezer and refrigerator.
- Adjust the thermostat if temperature is recorded outside the recommended range and contact the vaccine manufacturer.
- Temperatures should be recorded at least twice each day on a temperature log posted on or next to the refrigerator.
