Study Endpoints

Primary Endpoints

Number of Subjects With Solicited Local Symptoms
During a 7 day follow-up period after each dose of vaccine and overall.

Assessed solicited local symptoms were ecchymosis, induration, pain, redness and swelling. Any = occurrence of symptom regardless of intensity grade. Grade 3 Pain = pain that prevented normal everyday activities Grade 3 ecchymosis/induration/redness/swelling = redness/swelling spreading beyond (\>) 50 millimeters (mm) in diameter

Number of Subjects With Solicited General Symptoms (Dose 1)
During the 7-day (Days 0-6) after Dose 1

Assessed solicited general symptoms were arthralgia, fatigue, fever \[defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)\], headache, myalgia, shivering, sweating. Any = occurrence of symptom regardless of intensity grade and relationship to vaccination. Grade 3 symptom = symptoms that prevented normal activity. Grade 3 Fever = fever higher than (\>) 39.0 °C. Related = symptom considered by the investigator to be casually related with the study vaccination.

Number of Subjects With Solicited General Symptoms (Dose 2)
During the 7-day (Days 0-6) after Dose 2

Assessed solicited general symptoms were arthralgia, fatigue, fever \[defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)\], headache, myalgia, shivering, sweating. Any = occurrence of symptom regardless of intensity grade and relationship to vaccination. Grade 3 symptom = symptoms that prevented normal activity. Grade 3 Fever = fever higher than (\>) 39.0 °C. Related = symptom considered by the investigator to be casually related with the study vaccination.

Number of Subjects With Solicited General Symptoms (Across Doses)
During the 7-day (Days 0-6) post vaccination across dosses

Assessed solicited general symptoms were arthralgia, fatigue, fever \[defined as axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)\], headache, myalgia, shivering, sweating. Any = occurrence of symptom regardless of intensity grade and relationship to vaccination. Grade 3 symptom = symptoms that prevented normal activity. Grade 3 Fever = fever higher than (\>) 39.0 °C. Related = symptom considered by the investigator to be casually related with the study vaccination.

Number of Subjects With Unsolicited Adverse Events (AEs)
During the 21st Day (Days 0-20) post Dose 1

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. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination. Related symptoms were not available.

Number of Subjects With AEs
During the 30 Day (Days 0-29) post Dose 2

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. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination. Related symptoms were not available.

Number of Subjects With Serious Adverse Events (SAEs)
From Day 0 to Day 180

SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.

Number of Subjects With New Onset Chronic Diseases (NOCDs)
From Day 0 to Day 180

NOCDs include autoimmune disorders, asthma, type I diabetes, allergies.

Number of Subjects With Medically Significant Conditions (MSCs)
From Day 0 to Day 51

MSCs prompting emergency room or physician visits that were not related to common diseases or routine visits. Common diseases included upper respiratory infections, sinusitis, pharyngitis, gastroenteritis, urinary tract infections, cervico-vaginal yeast infections, menstrual cycle abnormalities and injury.
