Vacuum Refrigerators are designed to store vaccines and other medical products at stable temperatures to ensure they do not decrease. In a developing country with a sunny climate, solar-powered vaccine refrigerators are common.

Requirements for vaccine cooling
Many vaccines should be stored at low temperatures, some under -15 à ° C, and others between 2 and 8 à ° C. If the vaccine is not stored properly, they can lose their effectiveness.
The ideal temperature for storing vaccines in ILR is 2 degrees to 8 degrees
According to the Centers for Disease Control, failure to comply with the recommended specifications for immunobiological storage and handling can reduce or destroy their potential, resulting in inadequate or absent immune response at the recipient. Maintenance of vaccine quality is the joint responsibility of all vaccine handlers since the vaccine is produced up to the administration.
According to the Immunization Action Coalition, all vaccines should be stored in refrigerators or freezers specially designed for biological storage or, alternatively, in separate special units. The dorm-free cooling-freezer unit with only one exterior door has proven to be unacceptable wherever the vaccine is placed inside the unit. Stand-alone cooling or freezer units are best for storage needs. With retail pharmacies now playing a major role in pneumonia inflammation, influenza and herpes zoster programs, the value of critical vaccines stored in refrigerator pharmacies has reached new heights. In fact, it is not uncommon that many pharmacies now have more than $ 100,000 of products in a single refrigerator during peak season.
It is estimated that $ 20 million is wasted each year from poor cooling, and up to 35% of vaccines are affected by improper storage. Accurate and uniform temperatures in the refrigerator play a key role in ensuring the life of vaccines, reagents and other biologicals. Research has shown that small variations in temperature like in a household refrigerator can harm your biological effectiveness, risking up to thousands of dollars in precious content.
In the refrigerator and freezer, the vaccine is also compromised through the use of inappropriate door gasket to feed the cable from the data recorder and thermometer, allowing deeper warm air, and cold air out of the refrigerator or freezer. Over time this causes the compressor to work harder and eventually lead to failure. This can be fixed by using a probe access port, found in most refrigerators and clinical freezers. It's easy to open and drastically reduces air intake and losses from within the unit.

Solar-powered vaccine refrigerator
In developing countries electricity networks often do not reach rural areas, and are not always reliable. Because keeping the vaccine at the right temperature is very important, the solar-powered refrigerator is a cost-effective alternative that can be very reliable. A typical system will use photovoltaic solar panels to generate electricity from sunlight, and an in-cycle battery to store energy for overnight operations, although new refrigerators that have Sure Chill Technology or Direct Drive technology do not need revolutionary batteries to maintain temperature for some day. without sunlight.
WHO approved products
The World Health Organization maintains a list of products related to vaccines that are approved for use, including refrigerators.
