PEG in mRNA Vaccines

Of all approved COVID-19 vaccines in the market, the vaccines developed by BioNTech/Pfizer and Moderna represent a new class of vaccine products: they are composed of messenger ribonucleic acid (mRNA) strands encapsulated in lipid nanoparticles (LNPs).

The LNPs in mRNA covid-19 vaccines consist of four main components: a neutral phospholipid, cholesterol, a polyethylene-glycol (PEG)-lipid, and an ionizable cationic lipid, among them, PEG can enhance the stability and lifespan of LNPs.
