Study Endpoints
Primary Endpoints
The Number of Anti-HBs Seroprotected Participants 1 Month After the Third Dose.
11 months (1 month after the third dose)

The number of participants as measured by the seroprotection rate (anti-hepatitis B surface antibodies greater than or equal to 10 mIU/mL). Anti-HBs (Antibodies against hepatitis B surface antigen) titers were measured from blood samples taken at Month 11 (1 month after the third dose)

The Anti-HBs GMT (Geometric Mean Titer) 1 Month After the Third Dose.
11 months (1 month after the third dose)

Geometric Mean Titer (GMT) - This is an Antibody titer that is measured using a laboratory test to detect the presence and amount of antibodies in a person's blood. Anti-HBs (Antibodies against hepatitis B surface antigen) and Geometric Mean Titers were measured from blood samples taken at Month 11 (1 month after the third dose).

Secondary Endpoints
The Total Number of Participants With Serious Vaccine-Related Clinical Adverse Experiences
0-11 months (recorded from first dose until the participant completes or discontinues)
The Number of Anti-PRP Seroprotected Participants 1 Month After the Third Dose.
11 months (1 month after the third dose)
The Anti-PRP GMT (Geometric Mean Titer) 1 Month After the Third Dose.
