Overview
The purpose of this study is to evaluate the safety and immunogenicity an investigational messenger ribonucleic acid (mRN)A vaccine for the prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) and/or human metapneumovirus (hMPV) in older adults. A single intramuscular (IM) injection of 3 to 4 different doses of the RSV/hMPV mRNA vaccine candidate formulated with 2 different lipid nanoparticles (LNP) will be administered to healthy participants aged 18 to 49 years and 60 years and older.
- Treatment
-
- RSV/hMPV mRNA / LNP 1 at 3-4 different doses or,
- RSV/hMPV mRNA / LNP 2 at 3-4 difference doses or,
- RSV mRNA / LNP 1 at 1 dose or,
- hMPV mRNA / LNP 1 at 1 dose
