Messenger ribonucleic acid (mRNA):
Nucleoside-modified mRNA encoding the viral spike (S) glycoprotein of SARS-CoV-2
Purpose
Provides instructions 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):
- 2[(polyethylene glycol (PEG))-2000]-N,N-ditetradecylacetamide
- 1,2-distearoyl-sn-glycero-3-phosphocholine
- Cholesterol (plant derived)
- ((4-hydroxybutyl)azanediyl)bis(hexane-6,1-diyl)bis(2-hexyldecanoate)
Purpose
Work together to help the mRNA enter cells.
Sugar and acid stabilizers:
- Sucrose (table sugar)
- Tromethamine
- Tromethamine hydrochloride
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.
