Vaccine storage

Ultra-low temperatures are essential for the safe and effective storage of vaccines, particularly those that are biologically sensitive or rely on delicate components like mRNA or live-attenuated viruses. By preserving the stability of vaccines, inhibiting microbial growth, and ensuring long-term storage, ultra-low temperature freezers play a pivotal role in maintaining the potency and safety of vaccines. 

This technology also supports the global distribution of vaccines, especially in emergency situations or regions with limited cold storage infrastructure. Ultra-low temperature storage is therefore indispensable in modern immunization efforts, ensuring vaccines remain effective from production to administration.

Many vaccines contain proteins, such as antigens, which can degrade at higher temperatures. Freezing these components at ultra-low temperatures prevents the proteins from unfolding, aggregating, or denaturing, thus preserving the vaccine's effectiveness. For vaccines that use messenger RNA (mRNA) or DNA (such as COVID-19 vaccines), ultra-low temperature storage is essential. Freezing them at -70°C maintaining the vaccine's ability to trigger the immune response when administered.
