This Swedish startup is making powdered vaccines that don’t need to be kept cold

Pfizer’s COVID-1 9 inoculation needs to be stored at minus 94 degrees Fahrenheit. A pulverized vaccine wouldn’t need refrigeration at all.
When Pfizer’s new COVID-1 9 inoculation is approved for use–which might happen as soon as December–it’s not going to show up at your neighbourhood pharmacy. That’s partly because it needs to stay incredibly freezing to work: It must be stored at minus 94 magnitudes Fahrenheit, far colder than is possible in an regular freezer. In the developing countries, even vaccines that can be stored in refrigerators present a huge logistical challenge. A Swedish startup is working on an alternative: engineering that can convert any vaccine to a pulverized version that can survive without refrigeration.
