One thing I noticed at the beginning of the pandemic, there was a big concern about making sure that the vaccines stayed at very low temperature, or they would lose effectiveness. Hospitals and clinics were concerned because few had the necessary freezers. Suddenly, with no explanation or further discussion, this problem just "disappeared". Molecular destabilization or the thermal degradation of delicate organic molecules isn't a problem that just disappears.
