How Do You Keep Vaccines Cool? Try Spacecraft Insulation
If you’ve ever been vaccinated, you may have seen the nurse head out of the room to go to the refrigerator to retrieve your injection. That’s because most vaccines must be refrigerated during travel and storage or they lose their effectiveness.
Vaccines typically need what’s known as a “cold chain.” From the point of manufacture to the place where they’re used, they need to be kept within a narrow temperature range, typically between 35 and 46 degrees Fahrenheit.
When a vaccine heads out into regions where the power supply is spotty at best, that “cold chain” can be hard to achieve. From places deep in the Himalayas of Nepal to remote villages in Benin, the refrigeration services needed to store vaccines cannot be maintained.
