Study Summary

The purpose of this study is to assess the safety, reactogenicity, immunogenicity and long-term persistence of immune response up to 5 years following a single dose vaccination of GSK's investigational vaccine RSVPreF3 OA, in adults aged 60 years and above. The study will also evaluate the immunogenicity, safety and reactogenicity of additional vaccine doses given according to different revaccination schedules.

Primary Outcome

RSV-A neutralizing antibodies were given as GMTs and expressed as Estimated Dose: serum dilution giving a 60% reduction of the RSV plaques compared to a control without serum (ED60).
