Description

mRNA-1647 is a vaccine candidate combining six mRNAs in a single vial, which encode for two antigens on the surface of CMV: five mRNAs encoding the subunits that form the membrane-bound pentamer complex and one mRNA encoding the full-length membrane-bound glycoprotein B (gB)

Indication

mRNA-1647 is designed to produce an immune response against both the pentamer and gB for the prevention of CMV infection.

Dosage

Studies are on-going to determine the proper dosage
