Primary Objective: To describe the antibody long term persistence at 3.5 and 4.5 years of age following a 3 dose primary series vaccination of either DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + Oral poliovirus vaccine (OPV) + Engerix™ B vaccination at 6, 10 and 14 weeks of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + OPV at 15-18 months
Read the detailed description
All participants must have received the primary series of vaccinations and a booster vaccination in Study A3L15 (NCT 00362336).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Group 1 | Participants previously received 3 doses and a booster dose of the investigational vaccine DTaP IPV Hep B PRP-T. | |
| Group 2 | Participants previously received 3 doses CombAct-Hib™ + Engerix™ B + OPV and a booster dose of CombAct-Hib™ + Oral poliovirus vaccine (OPV) vaccine. | |
| Group 3 | Participants previously received 3 doses DTaP IPV Hep B PRP-T; a dose of Engerix™ B at birth, and a booster dose of DTaP IPV Hep B PRP-T vaccine. |
What is being measured
The primary outcome is the main question the study is designed to answer.
The antibody titers for each valence of DTaP-IPV-Hep B-PRP-T vaccine (except poliovirus) post-primary and booster vaccination.
Measured: Age 3.5 and 4.5 years after infant and booster vaccination

Questions about this trial
What is this clinical trial studying?
An observational study of Diphtheria and Tetanus, run by Sanofi at 2 sites in South Africa.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 13 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in South Africa. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The antibody titers for each valence of DTaP-IPV-Hep B-PRP-T vaccine (except poliovirus) post-primary and booster vaccination. (time frame: Age 3.5 and 4.5 years after infant and booster vaccination). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Dec 2011.
