FORMULATIONS: 5 Years of Age and Older 

Pfizer-BioNTech COVID-19 Vaccine

Temperature Log for Ultra-Cold Vaccine Storage (Celsius) Days 1–15

Store COVID-19 vaccine (Pfizer) between -90°C and -60°C. Using a digital data logger (DDL), check and record the temperature daily using one of the options below. Save this 

record for 3 years, unless your state/local jurisdiction requires a longer time period. See CDC’s Vaccine Storage and Handling Toolkit, COVID-19 Addendum, for additional information.

Option 1: Minimum/Maximum (Min/

Max) Temperatures (preferred)

1. Most DDLs display minimum and maximum 

temperatures. Check and record the min/max 

temperatures at the start of each workday.

2. Document these temperatures in the min/max 

temperature row under the appropriate date.

Option 2: Current Temperature

1. If the DDL does not display min/max temperatures, check and 

record the current temperature at the start and end of the workday.

2. Document these temperatures by writing an "X" in the row that 

corresponds to the freezer temperature under the appropriate day 

of the month. 

3. Review the continuous DDL temperature data daily.

If the temperature is out of range, 

TAKE ACTION!

1. Do NOT discard the vaccine.

2. Label the vaccine “Do Not Use.”

3. Complete the Vaccine Troubleshooting Record. 

4. Contact the manufacturer to determine under

what conditions (frozen or refrigerated) to store

the vaccine as quickly as possible.
