Outcome Measures

Primary Outcomes (1)

  • Geometric Mean Anti-PRP (Polyribosyl Ribitol Phosphate) Concentrations at Day 1 (4 Years Post Booster Dose Administered in Study V37_07E1)

    Immunogenicity was measured as geometric mean of Anti- PRP Concentrations, approximately 4 years after booster vaccination with either Hib-CRM197 or Hib-TT in children participating in previous V37\_07E1 trial.

    At Day 1 (4 years post booster dose administered in study V37_07E1)

Secondary Outcomes (1)

  • Percentages of Subjects With Anti-PRP Concentrations ≥1.0 μg/mL and ≥0.15 μg/mL at Day 1 (4 Years Post Booster Dose Administered in Study V37_07E1)

    At Day 1 (4 years post booster dose administered in study V37_07E1)

Study Arms (2)

Hib CRM197

EXPERIMENTAL

Subjects treated with 3 doses of CRM 197 -conjugate Haemophilus influenzae type b vaccine (study vaccine): 2 doses given one month apart during study V37\_07 (NCT01044316) and a booster dose of the same vaccine six months after, during study V37\_07E1 (NCT01226953). No vaccine was administered during this trial

Biological: Hib-CRM197

Hib TT

ACTIVE COMPARATOR

Subjects treated with 3 doses of Tetanus Toxoid-conjugate Haemophilus influenzae type b vaccine (comparator vaccine): 2 doses given one month apart during study V37\_07 (NCT01044316) and a booster dose of the same vaccine six months after, during study V37\_07E1 (NCT01226953). No vaccine was administered during this trial

Biological: Hib-TT

Eligibility Criteria

Age5 Years - 6 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Children previously enrolled in V37\_07E1 study and who received the appropriate vaccination.
  • Children whose parent(s) or legal guardian(s) had given written consent after the nature of the study was explained according to local regulatory requirements.

You may not qualify if:

  • Any confirmed or suspected current immunosuppressive or immunodeficient condition since the end of V37\_07E1 study, based on medical history and physical examination (no laboratory testing required).
  • Treatment with corticosteroids or other immunosuppressive/immunostimulant drugs as defined below:
  • i) chronic use of oral and parenteral immunosuppressants (\>= 15 days of use) or other immune-modifying drugs within 60 days prior to the blood sampling (short term usage of topical, inhaled and/or intranasal corticosteroids were allowed) ii) receipt of immunostimulants within 60 days prior to Visit 1
  • Administration of immunoglobulins and/or any blood products up to 3 months before enrollment.
  • Use of any investigational or non-registered product (drug or vaccine) within 30 days preceding the blood sampling.
  • Any condition, which, in the opinion of the investigator, might be a contraindication to the execution of the blood draw.
