Considerations When Storing Vaccine in a Freezer    

Before mixing, the vaccine may be stored in the freezer between -25°C and -15°C (-13°F and 5°F) for up to 2 weeks.

• These temperatures are within the appropriate range for routinely recommended vaccines, BUT the temperature range for this vaccine is tighter.
• If storing the vaccine in a freezer with routinely recommended vaccines, carefully adjust the freezer temperature to the correct temperature range for this vaccine.
  

Use CDC’s freezer storage temperature log for COVID-19 vaccine to document storage unit temperatures.

Monitor the how long the vaccine has been in the freezer using CDC’s Beyond-Use Labels for Pfizer-BioNTech COVID-19 Vaccine.

• Vaccine stored in the freezer can be transferred to refrigerator storage for an additional 1 month (31 days).
  

Store the vaccine in the tray.

Protect from light.

Do not use dry ice for freezer storage
