Temperature Monitoring Deep Frozen Vaccines

Many vaccines contain living cells, and so when stored for any length of time they must be kept within a suitable temperature range to prevent degradation. Vaccine shots that are allowed to fall outside the safe storage range quickly lose their potency, meaning patients may be poorly immunised or even gain no protection at all.

This requirement to control vaccine temperatures at all times has led to the development of the cold chain: storage, transport and monitoring procedures that ensure potency is protected from the manufacturer all the way to each individual patient. But existing cold chain storage and monitoring measures may not cope with the extremely low temperatures required for some recently developed vaccines.
