That was my initial suspicion, but it’s nonsensical when dealing with temperatures of -94ºF (Pfizer) and -4ºF (Moderna) and small volumes in vials.
In short, mRNA is so unstable (currently) that it’s frozen solid to thaw for use and uses PEG-2000 nanoparticles to both help protect the mRNA and assist the mRNA in cell penetration.
Thawed, those only last 6 hours. Those are so unstable who knows what the slightest temp change in the room could mean. Would they become useless in a warm room quicker than a cooler room and how would that affect someone getting jabbed at hour 5 vs. hour 6.25.
You know they’d stretch the time if they had a lot of vaccines just sitting around toward the end of the recommended time limit. Remember they were getting social outrage for giving it to those farther down the risk level.
Moderna is Gates’ and Fauci’s vax. No thanks.
