The Cold Chain is a system of transporting and storing vaccines within the safe temperature range of +2C to +8C.
The cold chain begins from the time the vaccine is manufactured, continues through to the state or territory vaccine distribution centre and immunisation service provider and ends when the vaccine is administered.
Immunisation providers must understand the principles of:
At the bottom of this page is a consolidated list of resources.
All immunisation providers responsible for ordering, storing, receiving and administering vaccines must understand the principles of vaccine storage.
The NSW Health Vaccine Storage and Cold Chain Management Policy provides mandatory requirements for the storage and management of vaccines in NSW public facilities.

Cold Chain Management
All vaccines MUST be stored within the recommended temperature range of +2°C to +8°C at all times. Maintaining the cold chain is important to ensure that effective and potent vaccines are administered to patients.
- A certificate of completion is awarded at the end of the module and should be saved for record keeping.
- All staff responsible for cold chain management in private facilities are encouraged to complete the module. This includes staff that manage, transport or administer vaccines and may include admin staff, cleaners, GPs and nurses.
- Staff working in NSW public facilities should refer to the Vaccine Storage and Cold Chain Management Policy for mandatory training requirements

Vaccine Storage self-audit
A vaccine storage self-audit must be completed every 12 months and more frequently where there have been problems with:
- Equipment or
- Cold chain breaches
The following tools are available to complete the audit:
Please contact your local public health unit on 1300 066 055 to discuss any concerns following the audit.

Managing a Cold Chain Breach
A cold chain breach occurs when vaccine storage temperatures have been outside of the recommended range of +2°C to +8°C during storage or transport. Excursions of >8°C to up to 12°C for no longer than 15 minutes may occur whilst restocking the refrigerator and are acceptable.
Immunisation providers must report all cold chain breaches to their local public health unit.
- Isolate vaccines and place a ‘DO NOT USE’ sign on the fridge.
- Continue to store vaccines between +2°C to +8°C. The vaccines may need to be transferred to an alternate purpose built vaccine refrigerator or cooler if available, see below.
- DO NOT DISCARD any vaccines.
- Download and review the data logging report to assess the duration of the breach and temperature the refrigerator reached.
- Complete the Cold Chain Breach Reporting Form and contact your local public health unit on 1300 066 055 as soon as possible during business hours to report the breach. If the breach occurs after hours, keep vaccines isolated until the next business day.
- If transferring vaccines to a vaccine cooler (eg Esky), record temperatures on the Vaccine Cooler Temperature Chart.
- Refer to the NSW Cold Chain Breach Protocol.

Ordering and receiving vaccines
Immunisation providers are responsible for:
- Ordering vaccines and maintaining appropriate levels of stock to meet practice vaccination program requirements while not exceeding the capacity of the refrigerator. (Immunisation providers should aim for one routine vaccine order per practice per month.)
- Ensuring that stock is rotated when receiving new stock to prevent wastage of vaccines nearing expiry.
When receiving a vaccine delivery it is important to confirm that the cold chain has been maintained during transport and the integrity of the vaccines has not been compromised.
Before accepting the delivery and transferring the vaccines to a dedicated vaccine refrigerator, check the cold chain monitors and record the check on the vaccine minimum/maximum temperature chart.
If the cold chain monitor(s) has activated contact the NSW Vaccine Centre immediately on 1300 066 055.
While awaiting advice, the vaccines must be:
- placed in the refrigerator
- isolated and
- labelled ‘DO NOT USE’
