What Temperature Ranges Do RNA Based Drugs Require for Safe Storage?
Ultra cold versus refrigerated storage. RNA based drugs fall into distinct temperature bands that dictate the equipment and protocols you need. mRNA vaccines are among the most demanding. Pfizer BioNTech’s COVID 19 vaccine originally required storage at around –80 °C, while Moderna’s vaccine needs –20 ºC; both maintain potency for up to six months. Newer formulations like SpikeVax and Comirnaty remain stable at room temperature for only 12 horas y 6 hours respectively. En contraste, siRNA and other RNA interference drugs such as Onpattro can be stored at 2–8 °C for three years. Gene and cell therapies often require –80 °C a –150 °C cryogenic conditions, making specialised freezers or liquid nitrogen vapour storage essential.
These differences originate from the inherent instability of mRNA molecules. They are prone to hydrolysis and chemical degradation when exposed to moisture or elevated temperatures. Lipid nanoparticles (LNPs) provide some protection but cannot eliminate the need for cold storage. Mientras tanto, siRNA molecules are smaller and more chemically stable, enabling longer shelf life at refrigerator temperatures.
Ultra Cold vs Refrigerated: Specific Temperature Bands
| RNA product type | Typical storage range | Ejemplo & significance | Your takeaways |
| Vacunas de ARNm | −80 °C (Pfizer BioNTech) o −20 °C (Moderna) a hasta 6 meses | SpikeVax and Comirnaty are stable at ambient temperature for only 6–12 hours. Temperature excursions can degrade the mRNA quickly. | Invest in ultra low temperature freezers, dry ice shipping and rapid distribution. Incorporate real time monitoring to catch excursions immediately. |
| siRNA drugs (p.ej., Onpattro) | 2–8 °C refrigerated; shelf life up to 36 meses | Onpattro shows that LNP formulations can be stable without cryogenic storage. | Standard medical refrigerators and validated packaging can maintain potency. Ensure long term monitoring for regulatory compliance. |
| Gene and cell therapies | –80 °C a –150 °C (criogénico) | CAR T cells and other gene therapies require liquid nitrogen or portable cryogenic freezers. | Use cryogenic freezers, liquid nitrogen vapour or portable ULT containers with alarm systems. |
| Freeze dried mRNA vaccines | 4 °C a 25 °C after lyophilisation; stability from weeks to 12 meses | Formulations with sucrose or trehalose can remain stable for up to one year at 4 °C. | Explore lyophilised formulations to reduce dependence on ultra cold storage; ensure reconstitution training and quality control. |
Practical Temperature Planning
Mapee su cartera de productos. Classify products into refrigerated, frozen and cryogenic categories. This ensures that each therapy is matched to appropriate freezers and packaging.
Build redundancy. Use backup generators and secondary freezers to prevent loss during power outages.
Validate packaging. Test insulated shippers and phase change materials for each temperature range. Dry ice and gel packs can maintain stable conditions for days.
Entrena a tu equipo. Many cold chain failures stem from human error. Establish clear handling protocols, labelling and contingency plans.
Ejemplo del mundo real: During the COVID 19 vaccine rollout, logistic providers scrambled to procure ultra low temperature freezers and dry ice shipping. In one instance, a shipment of mRNA vaccines to a remote clinic was saved when an IoT equipped cryogenic container automatically replenished dry ice mid journey, preventing a temperature excursion and ensuring the vaccines remained potent.
How Can Controlled Freezing, Thawing and Freeze Drying Extend RNA Shelf Life?
Avoiding cryoconcentration. Freezing and thawing RNA based medicines are not trivial. Slow freezing in conventional −40 °C freezers can lead to cryoconcentration—where water forms ice crystals that concentrate solutes, causing pH shifts and structural damage. Single Use Support notes that plate freeze–thaw systems enable controlled freezing rates, minimising concentration gradients and maintaining product quality. These systems freeze drug substance uniformly from both sides, reducing the risk of cryoprotectant segregation. Después de descongelar, controlled heating prevents temperature shocks and preserves LNP integrity.
Packaging and transport. Protective packaging is critical; heavy insulation, shock absorption and secondary containment prevent breakage and temperature excursions during transit. Use validated containers that withstand shipping hazards while maintaining internal temperatures. Cryogenic shippers and dry ice boxes must be correctly vented to avoid pressure build up.
Monitoring in real time. Advanced data loggers and IoT sensors provide continuous temperature, datos de humedad y ubicación. These devices alert you instantly when temperatures deviate from set thresholds, allowing corrective action. Many modern cryogenic containers incorporate built in sensors and GPS tracking, enabling remote control towers to oversee shipments and intervene before temperatures drift.
Freeze Drying and Cryoprotectants: Ampliación de la vida útil
Lyophilisation (freeze drying) removes water under vacuum and immobilises mRNA molecules in a solid matrix. This process drastically slows down hydrolysis and oxidation reactions, enhancing stability. Various excipients act as cryoprotectants and bulking agents to preserve LNP structure during drying and storage:
| Cryoprotectant formulation | Stability outcome | Beneficio práctico |
| 10% sucrose + 10% maltose (5 mM Tris buffer) | Physicochemical properties remain unchanged for 12 weeks at room temperature and at least 24 weeks at 4 °C. | Suitable for shipping where refrigeration is limited; ensures potency through distribution cycles. |
| 20% maltose (Tris buffer) | Lyophilised LNPs retain bioactivity for one year at 4 °C and stay stable at 25 °C for four weeks. | Extends shelf life dramatically, reducing reliance on ultra cold storage and enabling larger stockpiles. |
| 9% trehalose + 1% polyvinylpyrrolidone (PVP) | Minimal size increase over six months at 25 °C, maintaining encapsulation efficiency. | Ideal for high temperature environments; reduces risk during long transit or unexpected delays. |
| 10% sucrose + 5% trehalose | Stable at 4 °C for at least 12 meses and retains quality for 8 hours at room temperature after reconstitution. | Provides flexibility during last mile administration when mixing and dosing occur outside cold rooms. |
| 10% sucrose (PBS) | mRNA vaccines stored at −20 °C for at least 30 días with sucrose maintain transfection efficiency. | Offers an intermediate step for vaccines that cannot be fully lyophilised but require moderate sub zero storage. |
These findings highlight that lyophilised mRNA vaccines can remain stable for months in refrigerated conditions and weeks at room temperature. Sin embargo, reconstitution practices must be meticulous to avoid contamination or mechanical stress; training and standard operating procedures are essential.
Actionable Tips for Freezing, Thawing and Freeze Drying
Choose the right freezer: For ultra cold needs, invest in ULT freezers reaching −80 °C or −100 °C. Portable cryogenic freezers with battery backup are increasingly available.

Incorporate dry ice responsibly: Dry ice at −78.5 °C provides portable cooling and is widely used for shipping vaccines. Ensure proper ventilation and replenishment schedules; some containers now automatically replenish dry ice when sensors detect warming.
Use cryoprotectants wisely: Formulations like sucrose, trehalose and maltose protect LNPs during freeze drying, but concentrations must be optimized to avoid reconstitution difficulties.
Monitorear continuamente: Deploy IoT data loggers that transmit temperature and location data in real time. Integration with AI systems helps predict excursions and maintain compliance.
Estudio de caso: A biotech company preparing mRNA vaccines for a tropical region adopted plate freezing and lyophilisation with a 9 % trehalose + 1 % PVP formulation. The vaccines were stored at 25 °C for six months, dramatically reducing energy costs and enabling distribution without specialized freezers. Real time monitoring via IoT sensors alerted staff to one temperature spike during customs clearance. A portable cryogenic freezer was deployed for a few hours, preventing spoilage and ensuring the vaccines reached patients intact.
