En '''RNA-vaccine''' eller '''mRNA-vaccine''', dvs. '''messenger RNA-vaccine''', er en type [[vaccine]], der i stedet for at benytte et [[antigen]] til [[vaccination]], bruger en [[nukleinsyre]] ([[DNA]] eller [[RNA]]), i dette tilfælde et [[messenger RNA]] ([[mRNA]]), der koder for antigenet. mRNA’et koder f.eks. for et [[virus]]protein eller et [[kræft]]protein og indgår i cellens normale maskineri for at lave proteiner, se [[proteinbiosyntese]], hvorved der f.eks. produceres virusprotein eller kræftprotein, der inducerer et [[immunsystemet|immunrespons]].
