Outcome
- Type
- SECONDARY
- Title
- Number of Maternal Participants With at Least One AE Leading to Study Withdrawal From Day 1 to Day 181 Post-delivery
- Description
A participant was considered a 'withdrawal' from the study when no study procedure has occurred, no follow-up has been performed and no further information has been collected for this participant from the date of withdrawal/last contact. Participants who were withdrawn from the study because of AEs were clearly distinguished from participants who were withdrawn for other reasons. Investigators followed participants who were withdrawn from the study as a result of an AE until the event was resolved. At least one AE leading to study withdrawal = occurrence of at least one AE leading to study withdrawal regardless of intensity grade or relation to vaccination.
- Time frame
- From Day 1 to Day 181 post-delivery
- Population
- The analysis was performed on the Exposed Set for maternal participants, which included all maternal participants who received the study intervention.
