A Study on the Safety and Immunogenicity of Influenza, Respiratory Syncytial Virus, Human Metapneumovirus and Parainfluenza Vaccines in Adults 18 to 49 Years of Age.
Investigating the Safety and How the Body Defends Against Viruses with Respiratory Vaccines in Adults
Study Overview
The objective of this study is to evaluate the safety and immunogenicity of different vaccines of hemagglutinin formulations of trivalent influenza vaccine or of a combined respiratory syncytial virus / human metapneumovirus / parainfluenza virus type 3 vaccine in healthy participants 18 to 49 years of age. A lipid nanoparticle will be used in this study.
Overall, the study is designed to:
- Assess the safety profile of the candidate formulations
- Describe the immunogenicity profile of the candidate formulations
- Eligible participants will be randomized to receive a single intramuscular injection of either one of the vaccine formulations.
Participants will be provided with a diary to solicit reporting of injection site reactions and systemic reactions, unsolicited Adverse Events (AEs), Serious Adverse Events (SAEs) and Adverse Events of Special Interest AESIs).
Participants will also be required to record their daily temperature on the diary.
Study Details
The duration of study participation will be approximately 6 months for each participant.

This study investigates the safety and immune response of different vaccines for influenza, respiratory syncytial virus, human metapneumovirus, and parainfluenza virus in healthy adults aged 18 to 49. The purpose is to evaluate how well these vaccines work and their safety when administered to participants. A lipid nanoparticle is used in this study to deliver the vaccine formulations.
Participants will receive a single intramuscular injection of one of the vaccine formulations. They will be given a diary to record any reactions at the injection site, systemic reactions, and any adverse events. Participants are also required to track their daily temperature in the diary.
- Who can participate: Healthy adults aged 18 to 49. Female participants must not be pregnant or breastfeeding and must use effective contraception if of childbearing potential.
- Study details: Participants will receive one intramuscular injection of a vaccine formulation and will record any reactions or adverse events in a diary. Daily temperature recordings are also required.
- Study timelines: The study will last approximately 6 months for each participant.
