Preservation of recombinant human interferon a2b vaginal effervescent capsules

Hello! I have used ointment, recombinant human interferon a2b, etc. They are all in the university, and there is no refrigerator. When the outdoor temperature is MINUS 5 or 6 degrees, it will be 4 or 5 degrees at high temperature. My mother is a doctor, and she told me that recombinant human interferon a2b can be stored at 2-8 degrees, with the best curative effect! Storage temperature of 2-8 degrees will reduce the efficacy, and the greater the deviation of storage temperature, the worse the efficacy.
