What is a pharma cold chain system and why does it matter in 2025?
A pharma cold chain system is a temperature controlled supply chain designed specifically for medicines. It includes the storage, handling and transportation of temperature sensitive pharmaceuticals—vaccines, biológicos, insulina, monoclonal antibodies and advanced gene therapies. Most products are kept between 2 °C y 8 °C; some require freezing below –20 ºC o incluso –80 °C. Maintaining these conditions preserves potency and prevents degradation. A single temperature excursion can denature proteins, cause aggregation and lead to retiros de productos. With biologics accounting for roughly 30 % of all drugs and cell and gene therapies growing rapidly, robust cold chains are more critical than ever.
Why an unbroken cold chain matters
If vaccines or biologics are exposed to temperatures outside their designated range, they can become ineffective or even harmful. Insulina, Por ejemplo, loses potency if frozen. Durante el 2021 Covid 19 rollout, solo 14 % of doses reached poorer countries because of manufacturing and logistics issues. The World Health Organization estimates up to 50 % of vaccines are wasted in low resource settings due to temperature control failures. Claramente, a well designed cold chain isn’t just about compliance—it protects global health and public trust.
