I thought I heard something that it only needs to be stored at that temp if you want to keep it more than a week. Although that just leads to more questions, can it be stored at that temp until arrival at the GP's then left out in a lesser temp, as long has it is used within a week. Ie drip feed the GP's with supplies a week at a time. What happens to the dose after a week, does it become less effective, non effective. How do we know if the dose has protected us and the batch given was fit for purpose.
