Temperature Log for Vaccines (Celsius) 

Completing this temperature log: Check the temperatures in both the freezer and the refrigerator compartments 
of your vaccine storage units at least twice each working day. Place an “X” in the box that corresponds with 
the temperature and record the ambient (room) temperature, the time of the temperature readings, and your 
initials. Once the month has ended, save each month’s completed form for 3 years, unless state or local 
jurisdictions require a longer time period. 

If the recorded temperature is in the shaded zone: This represents an unacceptable temperature range. Follow 
these steps: 1. Store the vaccine under proper conditions as quickly as possible. 2. Call the vaccine 
manufacturer(s) to determine whether the potency of the vaccine(s) has been affected. 3. Call the immunization 
program at your local health department for further assistance: (_____) _________________. 4. Document the 
action taken on the reverse side of this log.
