An unsolicited AE covers any untoward medical occurrence in a 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 = occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to vaccination.	During the 28-day follow-up period (Days 0 to 27) after vaccination
Number of Subjects With Any and Related Serious Adverse Events (SAEs).	Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity. Any was defined as occurrence of any symptom regardless of intensity grade and related was an event assessed by the investigator as causally related to the study vaccination.
