The COVID-19 pandemic is unlikely to end the COVID-19 vaccines are rolled out across the globe to curb the spread of the novel coronavirus. Regulators in different countries have already authorised effective COVID-19 vaccines for human use, but their distribution to administration facilities has become a global challenge due to logistics challenges for universal access to vaccines. Generally, vaccines require ultra-cold chains as they have short shelf-lives once they are removed from storage, so the healthcare providers require specially designed biomedical refrigerators and freezers that maintain the efficacy of vaccines and other medical equipment. Inadequate storage and handling can make the vaccine useless and make one susceptible to contagious diseases. Understanding the importance of cold chain storage capacities, government bodies are working with key partners to solve the technical and logistical issue of vaccine storage as a part of worldwide immunization program.

Recently, Blue Star Limited launched a new range commercial refrigeration products and solutions for vaccine storage and transportation of vaccines to remote corners of India since they maintain desired ultra-low temperatures even while in transit. The specifically designed and temperature-controlled refrigerators and transporters introduced by the air conditioning and commercial refrigeration major, is a great move towards building a robust ecosystem for vaccine distribution in India.

What are biomedical refrigerator and freezer?

Biomedical refrigerators and freezers are designed specifically for the storage of biologic material. Unlike conventional refrigerators, medical-grade or biomedical refrigerators and freezers have a microprocessor-based system that accurately measures and maintains temperatures to maintain the potency of material stored. The biomedical refrigerators and freezers use digital sensors such as thermocouples, resistance temperature detectors, thermistors, and fast temperature recovery apparatuses to monitor the interior temperature and respond to out-of-range temperature readings.

Some medical-grade refrigerators and freezers are equipped with alarms that go off when the temperature goes out of pre-set temperature range and thermometers connected to glycol-encased probes to prevent possible temperature leaks.

Benefits of biomedical refrigerators

·         Ensure Reliable Cold-Chain Storage

According to CDC’s Advisory Committee on Immunization, every year healthcare clinics lose USD20 million due to cold-chain failures and put public life in danger. The biomedical refrigerators and freezers maintain a reliable cold chain that protect vaccines, blood transfusion, biologics, and extend the shelf-life of living organisms. Maintaining a tighter and more consistent temperature range, the compressors present in biomedical refrigerators and freezers reach target temperature faster and maintain them. Also, the medical-grade units also seal tighter and better than conventional household refrigerators.   

·         Provide Accurate Temperature Monitoring

Temperature excursions can lead to inappropriate conditions for the vaccine storage and require immediate action. The temperature reading outside of the biomedical refrigerator and freezers prevent any kind of an excursion event and facilitates tracking of internal temperature without opening the door of the appliance. The medical-grade refrigerators come with built-in digital data loggers (DDL), that provide accurate storage unit temperature information.

·         Promote better Air Flow

Biomedical refrigerators and freezers are designed to have a superior airflow as they rely on powerful and fan-forced air circulation systems with air-cooling vents. The internal shelving with perforated ventilation holes also facilitates efficient air circulation and ensure uniform temperatures. However, healthcare providers must avoid overcrowding, keeping the appliance only 30% full and ensure to place the units between the floor, ceilings, and any walls.

·         Prevents Unauthorized Staff Access

Some purpose-built biomedical refrigerators and freezers embed digital locks to restrict access to only authorized staff members. The medical-grade units may also include decals to label equipment for its intended use and prevent mixed storage to maintain potency of vaccines and other biologics.

·         Protects Biological Products from Temperature Excursions

Biomedical refrigerators have backup battery power sources that prevent damage to vaccines during power failures as they are ideal alternatives to generators. In case of temperature excursion, the units keep the doors closed to maintain the internal temperature.

Conclusion

From storage to administration, some of the most promising coronavirus vaccines require non-stop sterile refrigeration to stay efficient and safe. But it is a sad reality that nearly 3 billion people of the world’s population live where cold-chain is insufficient for an immunization campaign to bring COVID-19 pandemic under control. People living in developing countries who were among the hardest hit by pandemic are most to be last to recover from it as maintaining the “cold-chain” for coronavirus vaccines might not be easy even in developed nations due to lack of investment in infrastructure and cooling technology. As per an estimate, India has 30% less storage capacity than it would need for coronavirus vaccine and lack of public transportation presents another obstacle to getting citizens vaccine inoculated.
