Safety and Immunogenicity of mRNA-1653, a Combined Human Metapneumovirus (hMPV) and Parainfluenza Virus Type 3 (PIV3) Vaccine, in Healthy Adults, and Children 12-36 Months of Age With Serologic Evidence of Prior Exposure

Study Purpose

This clinical study will assess the safety and immunogenicity of 2 dose levels of mRNA-1653, a combined human metapneumovirus and human parainfluenza virus type 3 vaccine, in healthy adults (18-49 years of age) and 3 dose levels in children (12-36 months of age) with serologic evidence of prior exposure. The safety profile of the adult cohort will permit enrollment of the pediatric cohort.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

NCT04144348
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
