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.

Out of the 9 participants enrolled in the study, 1 participant withdrew consent before being assigned to any of the groups and was not vaccinated. 8 participants were vaccinated and were included in the Exposed set.
The study was planned to enroll 252 participants in 4 groups as per Protocol. However, due to early stoppage of enrolment and further vaccination, only 9 participants were enrolled in the study, out of which 8 participants were assigned to individual groups, except for the dTpa_RSV-P group, hence this group was not included in the results record.

| dTpa vaccine | Combination Product | Single dose of the dTpa vaccine was planned to be administered intramuscularly, in the non-dominant arm, at Day 1 or at Day 31, depending on the vaccination schedule. Two formulations of dTpa vaccine are licensed in the US and outside of the US (ex-US), respectively. dTpa-US formulation was administered to participants in centers located in the US, while dTpa-ex-US formulation was planned to be administered to participants in centers ex-US. The dTpa-ex-US formulation was not applicable in this study anymore as no non-US sites were initiated before the decision to stop the study. The participants in RSV_dTpa-P and RSV_dTpa-A study groups were provided with an option to decide to receive dTpa vaccination as part of standard of care/local recommendation on immunization. No vaccine was administered in the dTpa_RSV-P Group, since there were no participants assigned to it. |
