Messenger ribonucleic acid (mRNA):
Nucleoside-modified mRNA encoding the viral spike (S) glycoprotein of SARS-CoV-2

Purpose
Provides instructions that the body uses to build a harmless piece of a protein from the virus that causes COVID-19. This protein causes an immune response that helps protect the body from getting sick with COVID-19 in the future.

Lipids (fats):

PEG2000-DMG: 1,2-dimyristoyl-rac-glycerol, methoxypolyethylene glycol 1,2-distearoyl-sn-glycero-3-phosphocholine BotaniCholĀ® (non-animal origin cholesterol) SM-102: heptadecane-9-yl 8-((2-hydroxyethyl) (6-oxo-6-(undecyloxy) hexyl) amino) octanoate

Purpose
Work together to help the mRNA enter cells.

Salt, sugar, acid stabilizers, and acid:

Sodium acetate Sucrose (basic table sugar) Tromethamine Tromethamine hydrochloride Acetic acid (the main ingredient in white household vinegar)

Purpose
Work together to help keep the vaccine molecules stable while the vaccine is manufactured, frozen, shipped, and stored until it is ready to be given to a vaccine recipient.
