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, البيولوجيا, الأنسولين, monoclonal antibodies and advanced gene therapies. Most products are kept between 2 درجة مئوية و 8 درجة مئوية; some require freezing below -20 درجة مئوية or even –80 °C. Maintaining these conditions preserves potency and prevents degradation. A single temperature excursion can denature proteins, cause aggregation and lead to استدعاء المنتج. With biologics accounting for roughly 30 % من جميع المخدرات 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. الأنسولين, على سبيل المثال, loses potency if frozen. خلال 2021 Covid 19 rollout, فقط 14 % of doses reached poorer countries because of manufacturing and logistics issues. The World Health Organization estimates up to 50 % من اللقاحات تضيع in low resource settings due to temperature control failures. بوضوح, a well designed cold chain isn’t just about compliance—it protects global health and public trust.
