How Covid-19 Drove New Polio Cases in Afghanistan

Due to the pandemic, a total of 50 million children did not receive the polio vaccine in Afghanistan and Pakistan

Public health experts worry that vaccine availability will be further stalled by the Covid-19 pandemic

The vaccine candidate produced by Pfizer and BioNTech is stable at minus 94 degrees Fahrenheit, so Pfizer developed a suitcase-sized box that uses dry ice to keep between 1,000 and 5,000 doses that cold for 10 days.

Why the Most Promising Covid-19 Vaccines Require Super-Cold Storage

Both Moderna and Pfizer’s vaccines contain mRNA, which must be stored in frigid conditions
