Inclusion criteria

  1. Children previously enrolled in V37_07E1 study and who received the appropriate vaccination.
  2. 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.

Exclusion criteria

Exclusion Criteria:

  1. 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).
  2. 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

  3. Administration of immunoglobulins and/or any blood products up to 3 months before enrollment.
  4. Use of any investigational or non-registered product (drug or vaccine) within 30 days preceding the blood sampling.
  5. Any condition, which, in the opinion of the investigator, might be a contraindication to the execution of the blood draw.

  • Experimental
    Hib CRM197

    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

What researchers measure

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.

    Time frame: 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)

    Immunogenicity was measured as the percentages of subjects with Anti-PRP Concentrations ≥1.0 μg/mL and ≥0.15 μg/mL approximately 4 years after booster vaccination with either Hib-CRM197 or Hib-TT in V37\_07E1 trial.

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