Summary
Brief summary
The purpose of this study is to evaluate the ability of a single dose of the investigational
RSV Maternal vaccine, administered intramuscularly (IM) to pregnant women aged 18-49 years,
in good general maternal health, in preventing medically assessed RSV associated Lower
Respiratory Tract Illnesses (LRTIs) in infants born to vaccinated mothers. The study will
also evaluate the safety of the investigational RSV Maternal vaccine both in vaccinated
mothers and in their corresponding infant.

Following a recommendation from the Independent Data Monitoring Committee of NCT04605159 (RSV
MAT 009), GSK made the decision to stop enrolment and vaccination in the study. Ongoing study
participants will continue to be monitored as part of the study.
