Assessed solicited general symptoms were drowsiness, fever [defined as axillary, oral, tympanic or rectal temperature equal to or above (≥) 38 degrees Celsius (°C)], irritability and loss of appetite. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever higher than (>) 40.0 °C. Related = symptom assessed by the investigator as related to the vaccination.
Number of Subjects With Any Unsolicited Adverse Events (AEs) [ Time Frame: Up to 1 month post-vaccination ]
An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.
