Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the clinical lot-to-lot consistency of the respiratory syncytial virus (RSV) maternal (RSV MAT) vaccine administered to healthy non-pregnant women 18-49 years of age (YOA). In addition, this study will evaluate immunogenicity, safety and reactogenicity from co-administration of RSV MAT vaccine and GSK's quadrivalent seasonal influenza (Flu D-QIV) vaccine.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

RSV lot1 Group

Participants randomized to the RSV lot1 Group received one dose of RSV MAT Lot 1 vaccine intramuscularly at Day 1. Participants were also provided with an option of receiving Flu D-QIV vaccine at Day 31 to allow the participants receive the standard of care.

Group Type EXPERIMENTAL

RSVPreF3(120 μg)

Intervention Type COMBINATION_PRODUCT

A single dose of RSVPreF3(120 μg) combined with Sodium Chloride (NaCl) was administrated intramuscular (IM). There were used 3 different lots of RSVPreF3(120 μg), one for each individual group (RSV lot1 Group, RSV lot2 Group and RSV lot3 Group) considered under RSV pooled Group.

RSV lot2 Group

Participants randomized to the RSV lot2 Group received one dose of RSV MAT Lot 2 vaccine intramuscularly at Day 1. Participants were also provided with an option of receiving Flu D-QIV vaccine at Day 31 to allow the participants receive the standard of care.

Group Type EXPERIMENTAL

RSVPreF3(120 μg)

Intervention Type COMBINATION_PRODUCT

A single dose of RSVPreF3(120 μg) combined with Sodium Chloride (NaCl) was administrated intramuscular (IM). There were used 3 different lots of RSVPreF3(120 μg), one for each individual group (RSV lot1 Group, RSV lot2 Group and RSV lot3 Group) considered under RSV pooled Group.

RSV lot3 Group

Participants randomized to the RSV lot3 Group received one dose of RSV MAT Lot 3 vaccine intramuscularly at Day 1. Participants were also provided with an option of receiving Flu D-QIV vaccine at Day 31 to allow the participants receive the standard of care.

Group Type EXPERIMENTAL

RSVPreF3(120 μg)

Intervention Type COMBINATION_PRODUCT

A single dose of RSVPreF3(120 μg) combined with Sodium Chloride (NaCl) was administrated intramuscular (IM). There were used 3 different lots of RSVPreF3(120 μg), one for each individual group (RSV lot1 Group, RSV lot2 Group and RSV lot3 Group) considered under RSV pooled Group.

RSV+Flu pooled Group

Participants randomized in this group received one dose of RSVPreF3 vaccine (RSV MAT vaccine) from one of the three lots used (Lot 1, Lot 2 or Lot 3 of same formulation of RSVPreF3 vaccine) and one dose of the Flu D-QIV vaccine on Day 1, and were followed up until the end of the study (Day 181).

The participants in this group were considered for the immunogenicity and safety analyses of the RSV MAT and Flu D-QIV vaccines.

Group Type EXPERIMENTAL

Flu Quadrivalent influenza vaccine (15 μg HA)

Intervention Type COMBINATION_PRODUCT

A single dose of Flu Quadrivalent influenza (15 μg HA) vaccine was administrated intramuscular (IM).

Flu+Placebo Group

Participants randomized in this group received one dose of Flu D-QIV vaccine co-administered with one dose of placebo at Day 1, and were followed up until the end of the study (Day 181).

This group was considered comparator for immunogenicity and safety analyses for RSV+ Flu Pooled group.

Group Type ACTIVE_COMPARATOR

Flu Quadrivalent influenza vaccine (15 μg HA)

Intervention Type COMBINATION_PRODUCT

A single dose of Flu Quadrivalent influenza (15 μg HA) vaccine was administrated intramuscular (IM).

Placebo

Intervention Type COMBINATION_PRODUCT

* has practiced adequate contraception for 1 month prior to study intervention administration, and
* has a negative pregnancy test on the day of study intervention administration, and
* has agreed to continue adequate contraception during the entire treatment period and for 1 month after completion of the study intervention administration.
* No local condition precluding injection in both left and right deltoid muscles.

Exclusion Criteria

Medical conditions

* History of any reaction or hypersensitivity likely to be exacerbated by any component of the study interventions;

* Significant or uncontrolled psychiatric illness;
* Recurrent history or uncontrolled neurological disorders or seizures;
* Documented HIV-positive participant;
* Body mass index \> 40 kg/m\^2;
