Outcome
- Type
- PRIMARY
- Title
- Number of Participants With Vaccine-Related SAEs After Vaccine Administration
- Description
An adverse event (AE) is any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study vaccine. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an adverse event. A serious adverse event (SAE) is an AE that results in death, is life threatening, results in persistent or significant disability or incapacity, results in or prolongs a hospitalization, is a congenital anomaly or birth defect, is a cancer, or is an overdose. Vaccine-related SAEs are those deemed by the investigator to be definitely, probably, or possibly related to study vaccine.
- Time frame
- qHPV in Base Study: Up to Month 120; Placebo in Base Study: approximately Month 60 up to Month 120
- Population
- Participants who received \>=1 qHPV vaccination in the Base Study or EXT1 and had safety follow-up
