Principles of Vaccine Storage and Handling
• Success against vaccine-preventable diseases is impacted by proper storage and handling of vaccines
• Errors result in reduced potency and effectiveness
• It is better NOT to vaccinate than to administer a dose that has been mishandled
• Why worry about this?
![Page 7: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/7.jpg)
National Survey of Practices
• Survey of APIC Infection Preventionists • IRB approval University of Louisville• Web-based survey 38 questions 93 response items
Aims– Evaluate current healthcare worker immunization practices
in US healthcare facilities– Evaluate current vaccine handling and management
practices in employee/occupational health departments in US healthcare facilities

Significant Findings:Vaccine Handling
• 51% use a refrigerator type specifically contraindicated by CDC guidance
• 20% use calibrated thermometers• 28% report having to discard vaccine due to unsuitable
storage temperature events• 58% maintain redundant power to the vaccine
refrigerator• 31% use temperature-stabilizing strategies• 2% use a vaccine refrigerator to maintain cold chain
when vaccines administered outside the office (e.g., mobile carts)
![Page 10: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/10.jpg)
Significant Findings:Program Management
• 40.2% CIC• 2.4% COHN/COHN-S• 95% either completely or partially responsible for the
immunization program in their facility• 45.9% indicated they developed vaccine policy with
assistance of others (not physician)• 27.2% develop vaccine policy with assistance of
physician• 86.1% listed CDC/ACIP/Public Health as resources for
their programs
![Page 11: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/11.jpg)
Cold Chain
• From manufacturer to administration• Proper maintenance of vaccines during
transport and storage up to the time of administration
• Vaccines are fragile and subject to damage by exposure to temperature fluctuations
• Cumulative effect of temperature changes
![Page 12: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/12.jpg)
Frozen Vaccines
• Between -58°F and +5°F (-50°C to -15°C) • Varicella MUST be frozen and MMR MAY be frozen• Remove from frozen environment immediately before
reconstituting in preparation for administration• If necessary, non-reconstituted varicella vaccine may be
stored at refrigerated temperatures [35°F and 46°F (-2°C to 8°C)] for up to 72 continuous hours. Must be discarded after that time
• Must use diluent provided by the manufacturer• Diluent does not need to be refrigerated
![Page 13: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/13.jpg)
Refrigerated Vaccines
• Between 35°F and 46°F (-2°C to 8°C) • Desired average temperature of 40°F (5°C)• Proper environment for all inactivated
vaccines as well as some of the live attenuated vaccines– FluMist– Rotavirus– Typhoid (oral and injectable)– Yellow Fever
![Page 14: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/14.jpg)
Storage and Handling Plans
• Ordering and accepting vaccine deliveries• Storing vaccines• Handling vaccines• Managing inventory• Managing potentially compromised vaccines• Emergency retrieval and storage plan with
designated backup location
![Page 15: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/15.jpg)
Personnel Training and Education
• Where and how to order vaccine• How to receive, check, log, and store vaccine• Organizing within the refrigerator/freezer• Temperature monitoring• Daily physical inspection• Stock rotation• Expiration date monitoring• Response to temperature fluctuations• Overseeing proper vaccine transport• Documentation
![Page 16: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/16.jpg)
Refrigerator
• CC strongly recommends stand-alone freezers and refrigerators without freezers
• If a combination unit sold for home use is used, it must have separate exterior doors and thermostat controls for each compartment. This is acceptable but NOT recommended
• Dormitory style units are NOT acceptable• At least 4 inches between unit and a wall• 1-2 inches between bottom of unit and floor• No other use except vaccine storage
![Page 17: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/17.jpg)

Refrigerator
• Do not store vaccine in the door• Remove drawers, bins and shelves as they
impede air circulation• Do not store food in with vaccines• Daily physical inspection– Temperature– Proper placement of vaccines– Opportunity for air circulation
![Page 22: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/22.jpg)
Freezer
• Stand alone unit, or a combination unit designed to house vaccines
• Each refrigerated and frozen compartment must have own temperature monitoring process
• Check door seals and frost regularly. Should be frost-free unit
![Page 23: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/23.jpg)

Thermometers
• Calibrated thermometer• Certificate of Traceability and Calibration from an ISO 17025
accredited testing lab or another recognized standards agency– Digital– Bio-safe liquid– Continuous graphic
• Locate ideal thermometer placement by measuring in various locations to identify cold or hot spots
• Currently, temperatures must be monitored twice a day, but continuous monitoring recommendations are forthcoming
![Page 26: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/26.jpg)
Manual Temperature Log

Compromised Vaccine
• Rapid identification• Sequester in a refrigerated or frozen
environment• Label “Do Not Use”• Contact manufacturers for guidance• If identified after administration, contact
medical oversight and other experts to help determine plan of action. Patient safety first
![Page 28: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/28.jpg)
Error Proofing
• Store vaccines in labeled bins (uncovered)• Allow space between bins for air to circulate• Separate vaccines that may be confused (e.g., Td and
Tdap; Hepatitis vaccines)• Keep vaccines in their packages until ready to use.
May unpackage small numbers of vaccines that are expected to be used regularly.
• May keep diluents with refrigerated vaccines (check label requirements), but do not store diluents in freezer
![Page 29: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/29.jpg)

Error Proofing
• Plug unit directly into wall, not into power strip• Use plug guard• Label wall plug with a “Do Not Unplug” sign• Temperature alarm• Emergency generator/backup power• May keep bottled water in refrigerator and ice
packs in freezer to assist with temperature maintenance
![Page 31: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/31.jpg)

Expiration Dates
• Monitor vaccine and diluents• Rotate stock• Can use through end of day on the expiration
date. If expiration listed by month (e.g., 12/13), can use through end of last day of that month
• Multidose vial can be used until expiration date unless otherwise specified by manufacturer
• Date when opened• Never use expired vaccine or diluent
![Page 35: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/35.jpg)
Vaccine Transport to Off Site Clinics
• Minimize the number of times the vaccine is transported
• Multidose vial must be used by same user (office) as the one who opened it
• Maintenance of cold chain is critical• If in a cooler, monitor temperature hourly• Storage of diluent (room temperature) in cooler will
adversely impact the temperature inside the cooler• Patients should NEVER transport their own (or anyone
else’s) vaccine
![Page 36: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/36.jpg)

Vaccine Preparation
• Filling syringes in advance is discouraged• If done, any unused must be discarded at the
end of the clinic• If filling in advance, limit the number prepared
to prevent error and facilitate rapid use• Any prefilled syringe that has been “activated”
(needle applied) must be used or discarded by the end of the clinic
![Page 40: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/40.jpg)
Vaccine Disposal
• Expired or compromised vaccine may be returnable to the manufacturer
• Open files or activated pre-filled syringes are likely not returnable
• For return questions, contact manufacturer• For disposal, request guidance from pharmacy
partner. Disposal may require placement in accordance with new standards
![Page 41: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/41.jpg)
Performance Improvement
• Know existing processes• Evaluate your team’s understanding of the
policies/procedures• Observe practice• When deviation identified, promptly take
action• Engage others in the process so they can
identify defects in the system and correct
![Page 42: Approaches for Safe Vaccine Handling and Management Ruth Carrico PhD RN FSHEA CIC Associate Professor Division of Infectious Diseases University of Louisville.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649ebc5503460f94bc5c16/html5/thumbnails/42.jpg)
