Not only is PEG a wonderful stabilizer for mRNA vaccines, but PEG is a great wood preservative too!
I can just see the ad now with a pair of CUTE female twins: “PEG is a vaccine! NO, PEG is a wood preservative! Wait! PEG is both a vaccine AND a wood preservative!”

PEG is also used for colonoscopy lavage. You drink it and your intestine/colon contents are flushed out after a while. It is a real fun experience. /s
