Description
A serious adverse event (SAE) is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, or is another important medical event. An SAE was considered treatment-emergent if it was aggravated in severity or frequency following the administration of the study vaccine, up to and including the last visit of the study. AE is defined in outcome measure #10.
