That's a good question. I didn't research the temp requirements that deep myself yet. Instead I worked from what I read online and in the press. Which is also the way it works in Germany. Now I am intrigued so, I will see what I can find.

EDIT: This really is frustrating. Either I am unable to google stuff or there really is no data sheet on the Biontech vaccine available online. All I found is nice pictures and text without numbers at Pfizer's website and second hand interviews of Biontech CFO saying the vaccine can be stored up to 5 days in a fridge. Real transparency doesn't seem to be a thing with everything Covid-19.

This Pfizer site is intended for healthcare providers in the US so technically not meant for your eyes, but it has all the info: https://www.cvdvaccine-us.com/product-storage-and-dry-ice

The equivalent page for Germany where BioNTech distributes the same vaccine: https://www.comirnatyeducation.de/resources.html
