About this study

OBJECTIVES: I. Compare the safety and efficacy of acellular 2-component vs. acellular multicomponent vs. whole-cell pertussis vaccine vs. placebo in infants living in Sweden.

II. Compare the relative protection of each vaccine against atypical or subclinical pertussis infection.

III. Analyze possible laboratory correlates to vaccine protection.

Read the detailed description

PROTOCOL OUTLINE: This is a randomized, double-blind study. Patients are stratified by participating institution.

The first group of infants receives a vaccine composed of inactivated pertussis toxin (iPT) and filamentous hemagglutin (FHA).

The second group receives a vaccine containing iPT, FHA, pertactin, agglutinogen 2, and agglutinogen 3.

The third group receives a whole-cell pertussis vaccine. The fourth group receives a diphtheria-tetanus vaccine as the control. All vaccines are given as an intramuscular injection, at 2-3, 4, and 6 months of age.

Close surveillance of infants and families continues for 2-3 years.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing whole-cell pertussis vaccine and diphtheria-tetanus vaccine in people with Pertussis, run by National Institute of Allergy and Infectious Diseases (NIAID).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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.

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 24 Jun 2005.
