Refrigeration for clinic and hospital vaccine storage
Vaccines are among the most temperature-sensitive products a clinic handles. Most must be stored between +2 and +8 °C, and many are damaged by freezing as well as by warming, often without any visible change. A clinic or hospital that vaccinates needs refrigeration that holds a stable temperature, is monitored, and has a plan for power cuts. Public immunisation programmes have their own cold-chain equipment and procedures; private clinics, hospitals and paediatric practices choose their own equipment but must still follow manufacturer instructions and their regulator's and programme's guidance. This page explains equipment considerations only; it is not medical advice.
What the equipment has to cope with
- Many vaccines are damaged by freezing, so cold spots near cooling plates and air outlets are as dangerous as warm spots near doors.
- Power cuts and voltage sags can take a refrigerator out of range, sometimes overnight when no one is there.
- Domestic refrigerators have uneven temperatures and are not designed for vaccine storage.
- Temperature records, alarms and procedures for excursions are expected by programmes and regulators.
- Outreach sessions and transfers need ice packs that are conditioned correctly so they do not freeze vaccines.
Typical temperatures
| Most vaccines | +2 to +8 °C, as labelled |
|---|---|
| Freeze-sensitive vaccines | +2 to +8 °C, never freeze |
| Ice packs for transport boxes | Frozen, then conditioned |
| Vaccines labelled for frozen storage | As per manufacturer label |
Equipment
What to buy, and why.
A clinic typically keeps vaccines in a dedicated refrigerator used only for vaccines, set around +5 °C, with an independent calibrated thermometer or data logger and an alarm, checked and recorded at least twice a day. Vaccines are kept in their original packaging, away from the walls and cooling plate, with space for air to circulate. A separate freezer prepares ice packs for outreach and transfers, which are conditioned before use so they do not freeze vaccines. Plan for power cuts: know how long your refrigerator holds temperature, connect it to backup power, and have a written procedure for excursions.

Questions
- What temperature should a vaccine refrigerator be set at?
- Most vaccines are stored between +2 and +8 °C. Setting the refrigerator around +5 °C leaves margin on both sides. Always check each vaccine's label and follow your programme's and the manufacturer's instructions.
- Why should vaccines not be stored in a domestic refrigerator?
- Domestic refrigerators can have large temperature swings and cold spots, especially near the freezer section, that can freeze vaccines. Equipment with stable control and independent monitoring is safer. Follow your regulator's or programme's guidance on approved equipment.
- What should we do after a temperature excursion?
- Record the readings and duration, quarantine the affected vaccines in a working refrigerator, label them not to be used, and contact the manufacturer or your programme for advice. Do not use them until you have been told they are safe.
