https://www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines.html has lots of links to information about the three Covid-19 vaccines available in the USA.
https://www.fda.gov/media/144638/download#page=2 says the following:
"WHAT ARE THE INGREDIENTS IN THE MODERNA COVID-19 VACCINE?
The Moderna COVID-19 Vaccine contains the following ingredients: messenger ribonucleic acid
(mRNA), lipids (SM-102, polyethylene glycol [PEG] 2000 dimyristoyl glycerol [DMG],
cholesterol, and 1,2-distearoyl-sn-glycero-3-phosphocholine [DSPC]), tromethamine,
tromethamine hydrochloride, acetic acid, sodium acetate trihydrate, and sucrose."
Notice that the Moderna vaccine does not include ethanol and it appears (as far as I can tell) to not include any other alcohol. I received the Moderna vaccine - I chose that one specifically, because I had the impression it is likely the safest of the three vaccines, as well as being highly effective.
