Study of a Respiratory Syncytial Virus/Human Metapneumovirus/Parainfluenza Virus Type 3 Vaccine Candidate in Adults Aged 60 Years and Older

Phase 1
Active, not recruiting
Conditions
Respiratory Syncytial Virus Infection
Metapneumovirus Infection
Parainfluenzae Virus Infection
Interventions
Biological: RSV/hMPV vaccine
Biological: RSV/hMPV/PIV3 vaccine
Biological: parainfluenza virus type 3 vaccine (PIV3)
Biological: RSV vaccine 1
Biological: RSV vaccine 2
Registration Number
NCT06604767
Lead Sponsor
Sanofi Pasteur, a Sanofi Company
Brief Summary

The purpose of this phase 1 study is to evaluate whether the vaccine is safe and can help the body to develop germ fighting agents called "antibodies" (immunogenicity) against the respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and parainfluenza virus type 3 (PIV3). The study will use different doses of PIV3 only and different combinations of RSV/hMPV/PIV3 or RSV/hMPV or only RSV vaccine in adults aged 60 years and older.

Detailed Description

The study duration will be up to approximately 12 months minus the screening period.
