    Measured: During the 9-year period (January 2005- December 2014)

  2. Occurrence of ALRTI in infants ≤6 weeks of age and 7 weeks to ≤12 months of age, following the introduction of pertussis maternal immunisation in Bogota, Colombia

    Measured: During the 9-year period (January 2005- December 2014)

  3. Description of the total number of doses of Boostrix administered in pregnant women, after its introduction into the UMV program in Bogota

What are the possible benefits and risks?

Are results available for this study?

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?

It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02569879, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?
