Study Summary

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.

Primary Outcome

Assessed solicited administration site events include pain, erythema and swelling. This objective analyzed the safety and reactogenicity of RSV MAT vaccine when given alone (pooled lots) or co-administered with Flu D-QIV. As pre-specified in protocol, data reported in this outcome measure was presented for the pooled RSV and RSV+Flu groups and Flu+Placebo Group, since minimal differences were expected between participants who received different RSV lots of the vaccine.
