Outcome Measures

Primary Outcomes (1)

  • Protectivity

    Number \& percentage of subjects with anti HBsAg \> 10mIU/ml

    28 days after the primary series of Hepatitis B vaccination

Secondary Outcomes (7)

  • Immunogenicity: Serological response

    28 days after the primary series of Hepatitis B vaccination

  • Immunogenicity: comparison between IP & control

    28 days after the primary series of Hepatitis B vaccination

  • Immunogenicity: comparison among each batch of IP

    28 days after the primary series of Hepatitis B vaccination

  • Safety: Immediate reaction, Local and systemic events

    within the first 30 minutes, after 30 minutes to 7 days, after 7 days to 28 days after each injection

  • Safety: Serious adverse event

    from inclusion until 28 days after the last injection

  • +2 more secondary outcomes

Eligibility Criteria

Age10 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Healthy individual aged 10 - 50 years old, as determined by clinical judgment, including a medical history and physical exam which confirms the absence of a current or past disease state considered significant by the investigator.
  • Subjects/parents/guardian(s) have been informed properly regarding the study and signed the informed consent form/ informed assent form.
  • Subject/parents/guardian(s) will commit to comply with the instructions of the investigator and the schedule of the trial.

You may not qualify if:

  • Subject concomitantly enrolled or scheduled to be enrolled in another trial.
  • Subjects with known history of Hepatitis B contained vaccination in the last 10 years.
  • Evolving severe illness and/or chronic disease and fever (axillary temperature \>= 37.5 C) within the 48 hours preceding enrollment.
  • Known history of allergy to any component of the vaccines (based on anamnesis).
  • HBsAg positive.
  • Known history of immunodeficiency disorder (HIV infection, leukemia, lymphoma, or malignancy).
  • History of uncontrolled coagulopathy or blood disorders contraindicating intramuscular injection.
  • Subject who has received in the previous 4 weeks a treatment likely to alter the immune response (intravenous immunoglobulins, blood-derived products or corticosteroid therapy and other immunosuppressant.
  • Pregnancy \& Lactation (Adult).
  • Subject already immunized with any vaccine within 4 weeks prior and expects to receive other vaccines within 4 weeks following immunization.

Masking Details
The subject will be randomized and vaccinated per treatment group by unblinded team. The randomization list will be provided by unblinded personel of study team. This unblinded team will keep the list until Bio Farma formally issue the result of the study. Treatment will be allocated in accordance with a randomization list, so that to each randomization number, corresponds only one strictly randomly assigned treatment group (A/B/C/D).
