An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant or results in abnormal pregnancy outcomes. Any is defined as the occurrence of the symptom regardless of intensity grade or relationship to vaccination.
An AE is any untoward medical occurrence, symptom, or disease in a clinical study participant that is temporally associated with the study intervention. The AE may or may not be considered related to the study intervention. An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant or results in abnormal pregnancy outcomes. A participant is considered to have withdrawn from the study if no new study procedure has been performed or no new information has been collected for him/her since the date of withdrawal/last contact.
Assessed solicited administration site events include pain, erythema and swelling. Any pain = occurrence of the symptom regardless of intensity grade. Any erythema and swelling = symptom reported with a surface diameter lower than or equal to 20 millimeters.
Assessed solicited systemic events include fatigue, headache, gastrointestinal (GI) symptoms (nausea, vomiting, diarrhea, abdominal pain) and fever. The preferred location for measuring temperature is the oral cavity. Fever is defined as temperature equal to or above (≥) 38.0 °C/100.4°F. Any is defined as the occurrence of the symptom regardless of intensity grade.
An unsolicited AE is an event reported in addition to those solicited during the clinical study. Also, any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms is reported as an unsolicited adverse event. Any is defined as the occurrence of the unsolicited AE regardless of intensity grade or relationship to vaccination.
An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect in the offspring of a study participant or results in abnormal pregnancy outcomes. An MAE is an unsolicited AE for which the participants receive medical attention, defined as symptoms or illnesses requiring a hospitalization, or an emergency room visit, or visit to/by a health care provider.

| RSV_dTpa-P Group | EXPERIMENTAL | Healthy non-pregnant girls 9-17 years of age received a single dose of RSV MAT vaccine at Day 1 and were scheduled to receive a single dose of dTpa vaccine at Day 31 and to be followed-up until end of study (180 days post-vaccine administration). Participants who were enrolled and were due to receive the dTpa vaccine at Day 31, did no longer receive the dTpa as part of this study, but they were provided with an option to decide to receive dTpa vaccination as part of standard of care/local recommendation on immunization. |
| dTpa_RSV-P Group | EXPERIMENTAL | Healthy non-pregnant girls 9-17 years of age were scheduled to receive a single dose of dTpa vaccine at Day 1 and a single dose of RSV MAT vaccine at Day 31 and to be followed-up until end of study (180 days post-vaccine administration), but there were no participants assigned to this study group, and hence, there was no vaccine administered in this study group. |
| RSV_dTpa-A Group | EXPERIMENTAL | Healthy non-pregnant adult women 18-49 years of age received a single dose of RSV MAT vaccine at Day 1 and were scheduled to receive a single dose of dTpa vaccine at Day 31 and to be followed-up until end of study (180 days post-vaccine administration). Participants who were enrolled and were due to receive the dTpa vaccine at Day 31, did no longer receive the dTpa as part of this study, but they were provided with an option to decide to receive dTpa vaccination as part of standard of care/local recommendation on immunization. |
| dTpa_RSV-A Group | EXPERIMENTAL | Healthy non-pregnant adult women 18-49 years of age received a single dose of dTpa vaccine at Day 1 and were scheduled to receive a single dose of RSV MAT vaccine at Day 31 and to be followed-up until end of study (180 days post-vaccine administration). RSV MAT vaccine was no longer administered to participants at Day 31. |

| RSV MAT vaccine | COMBINATION_PRODUCT | Single dose of the RSV MAT vaccine reconstituted with NaCl solution was planned to be administered intramuscularly, in the non-dominant arm, at Day 1 or at Day 31, depending on the vaccination schedule. RSV MAT vaccine was no longer administered to participants at Day 31. No vaccine was administered in the dTpa\_RSV-P Group, since there were no participants assigned to it. |
| 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. |
