Vaccine storage,

[hawkdon]

can anyone tell me why one of the vaccines has to be stored at
75 BELOW zero?? Or maybe it's lower than that, not sure...but I do
not know why and would like to understand.

I think the latest vaccine that was announced does not have to be stored in such extremely cold conditions. It just needs ordinary refrigeration.

It's because the vaccines are freeze dried into powder form and they're kept frozen as the way to preserve them. They will add sterile water to liquify it right before the injection.
