Cold Chain Management in Your Pharmacy

The vaccine fridge is one of the most valuable cupboards in the pharmacy and usually the least managed. Stock sits in it that cost real money to buy, cannot be visually inspected for damage, and becomes worthless if the temperature moves for long enough. Unlike most inventory problems, you cannot see this one going wrong.

Key facts: vaccines must be stored between +2°C and +8°C, with +5°C as the target. The temperature has to be read and recorded twice a day, not simply monitored by a logger. A Western Australian audit found most providers reported high compliance overall, but 58 percent still needed follow-up support, most of it about equipment.

What the standard actually requires

The national reference is the Department of Health’s National Vaccine Storage Guidelines. The publication’s title refers to strive for 5 degrees Celsius, the midway point between +2°C and +8°C. Vaccines must always be stored and transported within that range, with an aim to store at +5°C, because many vaccines are compromised or destroyed outside it.

Three requirements do most of the work.

A purpose-built vaccine refrigerator. Domestic refrigerators, including bar fridges, are not built or designed to store vaccines and are not suitable for vaccine storage.

Twice-daily manual recording. Read and record the fridge temperature twice daily on the Strive for 5 temperature chart and reset the thermometer. A data logger does not replace this. It supplements it.

A documented breach protocol. Everyone on the roster should know what to do before it happens, not be working it out at 8am with a fridge reading +11°C.

The cold chain routine, in the order it happens

When	What	Why it matters
Twice daily	Read and record current, minimum and maximum temperatures, then reset	The only record that proves the chain held
Daily	Check stock rotation, shortest expiry to the front	Cold chain and expiry losses compound
Weekly	Review data logger output	Catches drift a twice-daily reading misses
On delivery	Check the cold chain was maintained in transit before accepting	Once accepted, the problem is yours
Annually	Service the fridge, verify the thermometer	Equipment was the most common audit gap

What an audit actually finds

This is the useful part, because it shows where confident pharmacies still come unstuck.

A public health audit in Western Australia surveyed general practices and community pharmacies against the national guidelines. Of 818 providers invited, 276 pharmacies responded, an 82 percent response rate. Over 70 percent met all procedural and emergency storage criteria, and 97.0 percent of pharmacies used a data logger.

Then the detail. The proportion measuring at 5-minute intervals, reviewing logger printouts weekly and manually recording minimum and maximum temperatures was lower. In total, 58 percent of providers required follow-up by a clinical nurse specialist, most regarding the need for equipment.

The pattern is worth sitting with. Almost everyone has a logger. Considerably fewer are doing the routine that turns a logger into evidence. Owning the equipment is not the same as running the process.

When the temperature goes out of range

The instinct is to throw the stock out. That instinct is wrong and expensive.

Do not use and do not discard vaccines exposed to temperatures outside the range without advice. Isolate them, label them so nobody administers them by accident, and report the incident. For National Immunisation Program vaccines, contact your state or territory health authority. For privately purchased vaccines, contact the manufacturer or supplier.

One nuance worth knowing, because it prevents needless panic. The guidelines note an exception for single temperature excursions up to +12°C lasting 15 minutes or less, such as when restocking the fridge. Those do not constitute a cold chain breach. That exemption does not cover excursions below +2°C. Freezing is treated more strictly than brief warming, because many vaccines are destroyed by freezing without any visible sign.

This is an inventory problem too

Cold chain gets filed under compliance, and that framing costs money. It is also stock control, with the same failure modes as the rest of your inventory.

Vaccine stock carries batch numbers and expiry dates, moves in and out seasonally, and is expensive per unit. The same discipline that stops expired and dead stock elsewhere applies here. One constraint is added: a temperature event can write off a batch that has not expired at all.

If you are growing a vaccination program, the fridge stops being a background cost and becomes a capacity constraint. We worked through the economics of that in what vaccination services actually pay a pharmacy.

Where Krepko fits

We build Emily, an AI voice agent for Australian pharmacies. She answers routine calls using your pharmacy’s own data and passes clinical or complex calls to a pharmacist. That keeps interruptions away from people doing checks that must be right first time.

We are also building an inventory platform for pharmacies. It tracks stock by batch, expiry and shelf, with low-stock and near-expiry alerts. Batch-level tracking is what a cold chain incident demands, when you need to know which stock was in the fridge and where it went. That platform is in development rather than released, so treat it as where we are heading rather than something you can buy today.
