mRNA vaccines

A syringe with a black ribbon-like substance attached to it, set against a blurred background of warm bokeh lights, symbolizes mRNA vaccines.

A class of vaccines that use messenger RNA to instruct host cells to produce a specific viral protein. This triggers an immune response and the creation of memory cells without ever exposing the patient to the actual virus. They were first deployed globally during the COVID-19 pandemic.
