I read that the Pfizer vaccine needs to be stored at - 80 C but is still viable for a couple of days at "higher", although still very cold, temperatures. According to the article I read they've designed a case which can keep it cold for 10 days as long as its not opened. I've recycled all the newspapers ( recycling was collected today ) so I can't check which one I read about the vaccine in but I
think
it was The Sunday Times (UK) 8th November.
