Official title

Phase I/II, Observer-blind, Safety, Reactogenicity and Immunogenicity Study of GSK Biologicals' Respiratory Syncytial Virus (RSV) Vaccine GSK3844766A in Subjects Aged 18-40 or 60-80 Years

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to assess the safety, reactogenicity and immune responses of two doses of the investigational RSV vaccines (with different formulations), when administered intramuscularly (IM) according to a 0, 2 month schedule, in older adults aged 60 to 80 years. As the investigational vaccines have not yet been tested in humans before, the study will first assess the safety, reactogenicity and immune responses in young adults aged 18 to 40 years. The study will thus be conducted in 2 parts (Part A and Part B).
