Clinical trial for Respiratory Syncytial Virus Infections+Metapneumovirus
Official title A Study of Investigational RSV/hMPV Combination and Investigational hMPV Vaccines in Younger and Older Adults
ClinicalTrials.gov ID: NCT07628049
What this study is testing
What is RSV/hMPV_V low dose vaccine?
An investigational injectable vaccine being studied to prevent respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) infections in younger and older adults. It is designed to stimulate the immune system to produce antibodies against RSV and hMPV.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see if the experimental RSV/hMPV combination vaccine and the experimental hMPV vaccine are safe and trigger an immune response in younger and older adults.
- Who it's for
- Adults who are either younger or older and have not been infected with RSV or hMPV recently.
- What's involved
- Participants will receive one of the study vaccines and will have blood draws and other safety checks to monitor reactions and immune response.
- Time commitment
- The trial lasts for several weeks with a few clinic visits for vaccinations and follow‑up tests.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
