Number of Subjects With Any Solicited Local AEs.
Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.
Time frame: During a 7-day follow-up period (from Day 60 to Day 66) after second dose.
Number of Subjects With Any Solicited General AEs.
Assessed solicited general symptoms are fatigue, gastrointestinal symptoms (included nausea, vomiting, diarrhoea and/or abdominal pain), headache, fever \[defined as oral temperature equal to or above 37.5 degrees Celsius (°C)\]. Any = occurrence of the symptom regardless of intensity grade.
Time frame: During a 7-day follow-up period (from Day 0 to Day 6) following the first dose.

Assessed solicited general symptoms are fatigue, gastrointestinal symptoms (included nausea, vomiting, diarrhoea and/or abdominal pain), headache, fever (defined as oral temperature equal to or above 37.5 °C). Any = occurrence of the symptom regardless of intensity grade.
Time frame: During a 7-day follow-up period (from Day 60 to Day 66) following the second dose.
Number of Subjects With Any Unsolicited AEs.
Assessed unsolicited AEs covered 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. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. Any = occurrence of the symptom regardless of intensity grade or relation to vaccination.
