Propylene glycol is also found in ice cream, liquid sweeteners, and soda. Very common in pharmaceuticals, including OTCs like Tylenol and Ibuprofen.Actually, the antifreeze suspicion is understandable. In post #24,132, the listed components for the Moderna vaccine includes propylene glycol. An internet search of antifreeze ingredients lists propylene glycol.
Easy to see how that would be interpreted as the vaccine contains antifreeze, even though it would be more correct to say the vaccine and antifreeze contain some of the same chemicals.
I find it interesting that some who would refuse to consume (for example) hot dogs because of the chemical preservatives have no problem injecting chemical preservatives as part of a vaccine (any vaccine, as I’m sure they all contain them).
Cherry picking + social media = uninformed righteous indignation
