Results
• What happened to the vaccine? Was it able to be used? If not, was it returned to the distributor? (Note: For public-purchase vaccine, follow your state/local health department instructions for vaccine disposition.)
After fridge thermostat repaired, monitored temps in empty fridge for 1 week, per state requirements. Fridge maintained 38 º-40ºF temps for entire
week. Submitted repair documentation and data logger readings to Victor Vaccine for approval and ordered replacement vaccines. Victor had checked
with manufacturers who confirmed that all vaccines in fridge EXCEPT MMR were no longer viable and should be returned per state policy
guidelines. MMR may be used because pkg insert allows storage down to -58ºF. Discussed entire situation with Susie Supervisor and clinic
director, Dr. Director, who agreed on continued use of MMR . Will continue to monitor fridge closely to watch for pattern of temp fluctuations
indicating potential problem with thermostat. If problems, contact Victor Vaccine for advice on purchasing new fridge meeting criteria for
appropriate vaccine storage.

When checked main clinic fridge (in lab) at 8:00 am on Tuesday, 7/16/2013, digital readout on data logger read 28ºF. Data logger located in
center of fridge with probe in glycol . Review of computer readings (taken every 15 minutes) showed steady drop in temps from 42ºF at 8:15 pm
(7/15/2013) to 28ºF reading discovered when arrived at clinic on Tuesday morning (7/16/2013). Readings hit 34 ºF at 11 pm (7/15) and 32 ºF
at 2 am (7/16). Total time out of recommended storage temps = 9 hours, with 6 hours at freezing or below (see attached document of continuous
temp readings). Inventory of vaccines attached.
Water bottles in refrigerator door and crisper area. No vaccines stored in freezer. No recent adjustments to temp controls and no previous temp ex-
cursions noted with this refrigerator before 7/15.
Upon discovery, vaccines marked “Do Not Use” and stored in 2nd clinic fridge (in exam room #3 at 41 ºF). Also placed “Do Not Use” note on main
fridge in lab. Notified Susie Supervisor about the issue. Contacted Victor Vaccine at My State Immunization Program at 8:30 am. Provided Victor
with details of event and list of vaccines in fridge. Victor said to maintain vaccines in 2nd fridge and that he would check with manufacturers to
determine next steps.
Called Jim’s Appliance Repair to examine fridge. Repairman found and replaced faulty thermostat in unit.
Reset data logger on center shelf in fridge with probe in glycol .
Description of Event
(If multiple, related events occurred, list each date, time, and length of time out of storage.)
• General description (i.e., what happened?)
• Estimated length of time between event & last documented reading of storage temperature in acceptable range (35

to 46
o
F [2

• Inventory of affected vaccines, including (1) lot #s and (2) whether purchased with public (for example, VFC) or private funds (Use separate sheet if needed, but maintain the inventory with this troubleshooting record)
• At the time of the event, what else was in the storage unit? For example, were there water bottles in the refrigerator and/or frozen coolant packs in the freezer?
• Prior to this event, have there been any storage problems with this unit and/or with the affected vaccine?
• Include any other information you feel might be relevant to understanding the event.
Action Taken
(Document thoroughly. This information is critical to determining whether the vaccine might still be viable!)
• When were the affected vaccines placed in proper storage conditions? (Note: Do not discard the vaccine. Store exposed vaccine in proper conditions and label it “do not use” until after you can discuss with your
state/local health department and/or the manufacturer[s].)
• Who was contacted regarding the incident? (For example, supervisor, state/local health department, manufacturer—list all.)
• IMPORTANT: What did you do to prevent a similar problem from occurring in the future?
