Study Summary

The purpose of this study was to evaluate the reactogenicity, safety and immune response of a single intramuscular dose of the respiratory syncytial virus maternal (RSV MAT) vaccine in healthy non-pregnant girls 9-17 years of age (YOA) compared to non-pregnant adult women 18-49 YOA. The combined reduced-antigen-content diphtheria, tetanus and acellular pertussis (dTpa) vaccine was planned to be used as an active control for safety and reactogenicity evaluation. Following a recommendation from the Independent Data Monitoring Committee of NCT04605159 (RSV MAT 009), GSK made the decision to stop enrolment and vaccination in this study. Enrolled study participants were monitored as part of the study until study completion.
