- PRIMARY
- Title
- Number of Participants With Laboratory Adverse Experiences
- Description
Number of participants with laboratory adverse experiences with an incidence cut-off of 5% (events occurring \> 5% in at least one treatment group) following administration of the first dose of study vaccine.~Laboratory AEs were based on a grading system considering the severity of abnormal laboratory values in participants and reflect any unfavorable and unintentional change in function, or chemistry of the body.~All laboratory AEs were collected up to 14 days after any vaccine dose.
