- Conditions
- Respiratory Syncytial Virus Infections
- Interventions
- Biological: RSVPreF3 vaccineOther: Control
- Registration Number
- NCT05705440
- Lead Sponsor

- Brief Summary
The purpose of this follow-up study is to describe the safety in subsequent pregnancies in participants who were previously administered the RSVPreF3 maternal vaccine or control during any prior RSV MAT study.
The study participants enrolled in this follow-up study received RSVPreF3 maternal vaccination (any dose) or controls during the following prior RSV MAT studies: RSV MAT-001 (NCT03674177), RSV MAT-004 (NCT04126213), RSV MAT-010 (NCT05045144), RSV MAT-011 (NCT04138056), RSV MAT-009 (NCT04605159), RSV MAT-012 (NCT04980391) and RSV MAT-039 (NCT05169905).
